What’s the most unexpectedly fuel efficient car you’ve ever had?
Posted by ChangeForAParadigm@reddit | cars | View on Reddit | 515 comments
My 2005 Ranger Ext. Cab 2WD 3L V6 Manual (Edge Trim: 4WD Ride Height) got 23 at 65 mph. I was poor back then and gas hit $5/gallon around 2008 so I couldn’t afford to drive faster.
thumpetto007@reddit
4 speed manual 1995 toyota tercel. That bitch got 42mpg NO MATTER WHAT. I tried hypermiling it... 42. Speeding on the highway for hours at a time? 42.
I still don't understand it.
unmanipinfo@reddit
Was it an E series engine? I swear those are one of Toyota's best. I have a 4e Starlet with a Weber 32/36 which puts it somewhere between 90-100bhp that I absolutely rip on and never drop below 35mpg, and that's with at least half city driving. Not to mention it's completely unkillable, perfect compression at 250k miles.
thumpetto007@reddit
I'm not sure what the engine was, it had vicious one wheel hop if I tried to take off in anger
It had a lot of space in the small engine bay, if that helps identify
Apparently it was a 1.5L in the DX model which is what I had. hven't found wht the engine code was though
unmanipinfo@reddit
Guessing it'll be the 5efe (unless it was a diesel lol)
I've always wanted a 2 door Tercel hatchback from that era (also called the Corolla II, weirdly) they look really fun
thumpetto007@reddit
Yeah, it was a 2 door, and the previous owner had cut out the rear bulkhead and installed a carpetted, wooden floor. It was like a mini pickup truck! i could fit three or four (i dont recall exactly) large beergas canisters in there!
unmanipinfo@reddit
Oh wow that's iconic. Japanese kei car kind of vibe, especially with the kegs haha
xqk13@reddit
42 really is the answer
auerz@reddit
Alfa Romeo Giulietta 2.0 JTDm, 220.000 km, 14 years old, the trip computer says the overall average is 5,3 l/100 km, so 44,4 mpg.
No_Skirt_6002@reddit
In our modern days of hybrids it’s easy to forget how fuel efficient diesels are.
auerz@reddit
My dad was really dissapointed when his brand new Opel Grandland X, with the 1,2l turbo, barely gets 7 l/100km, which is basically what his 2000 Nissan Primera was doing.
No_Skirt_6002@reddit
I think Europe jumped the gun a little bit when trying to get off diesel after dieselgate a few years ago. They had a good thing going, several of those diesel hatchbacks could do 60 mpg+ and the cost to fill up diesels is lower in the EU than gas because diesel is generally cheaper than gas. Diesel especially makes sense in the crossover SUVs that are taking over the old continent, much like the US, but most have ditched their diesel engines for plug in hybrid and mild hybrid systems.
RafaelSeco@reddit
Europe is still on diesel. The problem is that modern diesel cars are not good for short distances, and plug-ins/evs are great for that. For long distance driving, diesel is still king.
psoliakos17@reddit
We mostly abandoned them, right now diesel options are fewer compared to 10 years ago
auerz@reddit
Yeah I agree, and I feel it's becoming obvious especially to budget consumers. There is a real lack of good reliable cheap cars like you had 10 years ago - most of the entry level brands use 0,9-1,2 liter turbo gasoline engines, with many of them having horrible reliability, especially Fords and Stellantis groups wet-belt engines.
freddurstsnurstburst@reddit
Wet belts are indeed a nightmare over here. Many of the Fords have them and they're time bombs. For me it has always been chain or nothing. One less thing to worry about.
hutacars@reddit
They didn’t jump the gun— particulate emissions/NOx are particularly bad in diesels. MPG isn’t everything.
No_Skirt_6002@reddit
Many city centers in Europe have banned ICE cars from being there- as they should have a long time ago IMO, especially with how good their public transit is. The smog and particulate emissions created by diesels are less of an issue outside of cities, which trap the bad air in- but it's not like it's that huge an issue anymore, with how effective diesel aftertreatment equipment is these days. You want to know what has a real NOx problem? Direct injected gasoline engines produce extremely high NOx, with no AdBlue trap.
At this point in our planet's changing climate it really should be, especially when you can scrub out a lot of the bad stuff like NOx and particulates that's in diesel exhaust. Diesels have an undeniable advantage when it comes to CO2 compared to their gas counterparts, especially when you run them on the R99 Renewable Diesel that's already available in states like CA. R99 contains no aromatics, and therefore even untreated diesel exhaust running on R99 contains far less carcinogens compared to standard fossil fuel diesel- eliminating one concern there, and because it's renewable, net carbon emissions are substantially reduced. Studies have even shown that truck fleets running on R99 have significantly lower net carbon emissions over the truck's lifetime than even electric heavy duty trucks.
Obviously, electric is the way to go for small city cars, hatchbacks, sedans and crossovers. But for larger vehicles, or longer-ranged vehicles? Bring on the R99-running diesel hybrids!
FrenchyMcfrog@reddit
Why not more diesel hybrids 😢 only Mercedes and DS seem to make them
No_Skirt_6002@reddit
While I do think overall diesel hybrids would be a great idea, there are two things I can think of from stopping them from becoming popular.
1) Cost- diesel engines have to be built much stronger than equivalent gasoline motors, due to their higher compression ratios, therefore they cost more to make. Also for all practical purposes all new diesels are turbocharged, making them only more expensive to produce. Most hybrids use n/a Atkinson cycle gasoline engines; a diesel hybrid would have to have a stronger, turbocharged motor that would cost a bit more to produce, and combine that with the added cost of a hybrid system, it may not be worth the added MPGs over just a regular diesel or gas hybrid model.
2)Auto stop-start. From what I've seen, most diesels don't do auto-stop-start because it's generally a pain in the ass to get any diesel to start, particularly in colder temperatures. Because diesels operate at compression ratios around 1.5-2x that of gasoline engines, they're that much harder to turn over, and that much harder on the starter motor. I say most, because some, like GM's 3.0L Duramax motor, do use it, depending on load conditions and the temperature outside. Like, if your A/C is on full-blast or if it's 30 degrees outside it won't, but if it's 72 degrees and sunny with the windows down it will shut off at stop lights. I consider it a questionable design choice, but I'm not a GM engineer so what do I know. However, most if not all hybrid vehicles rely on auto stop-start to save fuel, generally shutting off if they're stopped for more than 30 seconds. It might be hard to achieve significantly better mpgs on a diesel hybrid when the engine is on and consuming fuel more often than an equivalent gasoline hybrid.
Przedrzag@reddit
Regarding your first point, Mercedes and DS have a better cost base for diesel hybrids as their petrol engines (including hybrids) are all turbocharged anyway.
ConfusedTapeworm@reddit
The auto stop-start of an ICE engine in a hybrid configurations is a different story than a purely ICE vehicle. Hybrids very often use the electric engines to start up the car and get it moving. Once that's done, you don't really need a starter motor because you've already got plenty of rotation you can use to get the engine started.
FrenchyMcfrog@reddit
Mercedes and ds do it, they must have found a way to optimize it I guess?
Regarding start stop, diesels are fine with it, any modern diesel will have start / stop at least here in Europe ( having to turn it off every single time you start the car is the pain tho)
Only real issues I’d say are engine cost, and dpf clogging that could be fixed if you changed the way the engine behaves I believe. I’m no expert obviously but I’m sure there’s a solution for that. About the turbo, it isn’t really necessary imho, na diesels are fine without one especially if you don’t rely all the time on them. But I guess it all comes down to emission standards that are really rough on diesel emissions here in Europe. Diesels have a bad reputation, but they are a lot cleaner than they used to be ! people should realize this
Elvis1404@reddit
Diesels can easily do auto stop-start since the common rail was invented (30 years ago), the problem is that running the engine only for short periods of time clogs the dpf filters. If you are sure to use the ICE part of a hybrid diesel pretty often it's not a problem (because the engine has time to hear up and burn the soot inside the filters), but if you drive mainly in electric mode the engine isn't able to clean the filters that will eventually get clogged
cbf1232@reddit
Diesels are great on long highway trips, not so great in city driving.
Also diesel has ~20% more energy per volume, so it should be giving at least 20% higher mpg than gasoline.
Elvis1404@reddit
Diesels are great in city driving, much better fuel consumption than gasoline (only surpassed by full hybrids) and the torque makes it almost impossible to stall them. The problem is that (especially the older models) they are not great on the lungs, but they at least produce less CO2 than gasoline engines (that's why EU incentivized them for decades)
cbf1232@reddit
According to Renault's comparison tool, the diesel Renault Clio gets around 5.6 L/100km in city driving, while the gas version gets around 7 L/100km. This maps closely to the ~20% more energy per volume contained in diesel fuel, which implies that (for this vehicle at least) there is relatively little inherent advantage in the diesel engine.
auerz@reddit
I mean it's a weird argument when in essence diesel engines are significantly different in their design due to using diesel fuel.
SupraMK4@reddit
My E46 320d did 4.5L/100km average and 3.5L/100km on the highway, that's 67 mpg
ConfusedTapeworm@reddit
Tbf that's not a crazy number for a 2.0l diesel. The most unexpected thing about it is that it's only 0.6l/100km higher than the official number.
jeremy26@reddit
My 911 can easily get high 20s, even low 30s on the highway. Newer turbo ones are probably even better
Vorcia@reddit
718 S, so it's kinda cheating bc it's a 4 cyl but on the highways, if you're literally just cruising is like 40mpg, more realistically if you're in the left lane and have to speed to pass people or not be a nuisance in the lane, it's also low 30s
Newflyer3@reddit
Late but any difference highway wise between the PDK and 6MT?
epsiblivion@reddit
but it's a 718 so i usually get 20-24 mpg avg. lower on fun drives of course
ucancallmevicky@reddit
same with mine
mr_lab_rat@reddit
I didn’t expect 30mpg from my 2017 BMW M2.
3.0L turbo 6 cylinder with 365hp, 0-60 in 4.1s
Obviously I can only get good fuel economy if I take it easy on the highway. City is around 20 and I can easily get into single digits on a racetrack.
jay_paj@reddit
Same, I was blown away by mine tbh.
It’s Stage 1 tuned and regularly get 35-37mpg on a motorway run at ~74mph, on 97 Fuel. I even did the maths on a whole tank once to check BMW weren’t inflating the numbers, and it was almost bang on.
That’s while running 410bhp too - awesome machine.
W9967@reddit
With a comp I get 21-22 mpg (10,5-11 L/100km) on the highway, crusing at 150-160 kmh.
It’s worse than I expected tbh. Combined with the small tank, I have fuel up every 380-400 kms.
mr_lab_rat@reddit
Yes, S55 is a bit more thirsty. But you get more power 😄
Skensis@reddit
Same with the B58 vs S58, the S engine gets like 7-8mpg worse.
Best I've ever gotten 24.5mpg on a highway only trip... Worse was like 5mpg on a track.
W9967@reddit
Yeah, I don’t have the patience for sitting at 120. Previous owner had 10,5 lifetime average. Not sure how he managed that when we have 140 speedlimit on highways. My curiosity of how fuel efficient this car can be went out the window after a week.
It’s gonna be contraversial with some S code engine nuts but N55 might be the better objective choice. Horse power difference is not that significant while N55s just sound better. Suspension components are the more important improvement over og/lci vs comps imho.
mr_lab_rat@reddit
I intentionally chose the N55, I bought it after the competition model came out. I didn’t like the S55 sound, the extra power wasn’t a deal breaker. The suspension is identical other than the front strut brace which I added. The comp seats look nicer but to be honest they are not that much better if you want to track the car.
Astramael@reddit
BMW has extremely good powertrain tuning. Pretty much always has.
Far_Helicopter385@reddit
My cammed ,built top end and tuned 2005 gmc Sierra crew cab 1500 4x4 6"lift on 35/12.50/22 I get 14-16 mpg
MQA_@reddit
Ok bear with me, but I've been getting 32MPG on my ND2 Miata. This is with plenty of stop and go traffic, and redlining it at least once per drive.
c53x12@reddit
I get over 36 in mine in mixed driving. In constant highway driving it routinely tops 40.
asad137@reddit
That is completely unsurprising for a lightweight car with a 2L 4cylinder.
MQA_@reddit
Agreed, but I was cross shopping with a GR86 which is rated at 24MPG combined.
My other option was a base cayman (27 MPG highway).
dylanv1c@reddit
I bought a 1996 Ford escort to deliver pizzas in a couple years ago. I was so shocked it got 28+ miles per gallon from the most outrageous suburban neighborhood driving, I was rarely cruising with it!
ThrowAndHit@reddit
C6 Corvette. In the fall/winter, no AC, 75mph on the highway, 6th gear, ~1700rpm, and 35-38mpg on wasn’t uncommon at all.
jrileyy229@reddit
35-38 mpg? No. Maybe if you are on the top of a mountain and reset the DIC then only measure while going down the other side of the mountain
maveric101@reddit
It's possible if you trail a semi the whole time. I've done 33/34 without getting extreme on the hypermiling techniques.
jrileyy229@reddit
Sure, downhill, tailwind, using a semi as a DRS device, going only 65mph... Put all those together and they'll add up for sure. But to say you get 35-38mpg highway regularly in your Corvette at 75mph is rubbish
ZannX@reddit
I own a C8... and there are so many MPG anecdotes lol.
My real stat is... 6500 mile road trip. Average 59.2 mph. 25.6 mpg. I can maybe flirt with 30 mpg in ideal conditions - but typically see around 26 when cruising. Everything stock.
jrileyy229@reddit
Yes, it's been going on a long time... It is the one stereotype that doesn't ever get talked about but is absolutely true in the c5/6 world:
You have the new balances, and the stupid 1 of 1 car show plaques, and the gaudy JC Whitney vent trims and fake brake calipers, and then the gross over exaggerating of MPG.
It's "that guy" that will tell you his '450hp Corvette (it's 350hp with an exhaust and intake that he believes adds 100hp) goes 0-60 in 3 seconds ALL while getting 35mph'
TappedOut182@reddit
I hated those guys when I had my C5. It was a 20+ year old Chevy that they made 250,000 of, not a bespoke supercar. Their beige automatic convertible with 2.73 gears wasn’t powerful enough to be “scary to drive”.
That said, when I would visit my friend which was a 300 mile round trip that was 95% highway I could easily get 32-35 MPG when I would reset the DIC and it typically proved out pretty close to a hand calc.
Around town it was closer to 21-22 MPG, but with the six speed you could easily get mid-30s on the highway as you weren’t much above idle.
jrileyy229@reddit
Not at 75mph you're not getting anywhere near 35mpg
TappedOut182@reddit
What did your C5 get for fuel economy?
jrileyy229@reddit
Under 10mpg
TappedOut182@reddit
Impressive!
Track only or constant stop and go? Even when I was on the loud pedal a bunch I rarely saw my cumulative economy drop below 20 in mixed use.
If you’re all stock and seeing those numbers in daily driving it might be worth doing a once over on your car because that’s half what you should be seeing.
firstorbit@reddit
Cylinder deactivation?
gropingforelmo@reddit
I don't think the C6 ever got cylinder deactivation, but maybe the automatic, if anything.
jrileyy229@reddit
Nope. Nobody has ever gotten a legitimate 35-38mpg in a c6. That's nonsense... Maybe someone once saw a "current mpg" reading flash up for a moment of 35mph when they were going down a 5% grade highway with a tail wind
glizzytwister@reddit
Lol it was not getting 35-38mph. That's what my 2021 4 cylinder Corolla gets.
MyName_isntEarl@reddit
I have an 80s trans am. One of the most aerodynamic production cars made... It looks blocky but that wedge is sleek and efficient.
I put in an LS1 V8 from a 2001 corvette, a t56 6 speed manual, 5th gear is an overdrive, 6th is even deeper. And I have tall rear end gearing.
If I cruised at 120km/hr, so 75mph, I absolutely did get 30 to 35 on the highway, IF I was very nice to the throttle.
More cylinders doesn't mean more wasted fuel. It's the entire package, and drag and weight is a huge part of that. The car is very sleek. You would be surprised by what can cause drag and how big of an effect it has. The car is actually just under 3,000lb... It's in the ballpark of your car.
Your engine is doing more rpm with more throttle to do the same speed. In a perfect world, the exact same car doing the exact same speed, with a perfectly efficient v-8 would burn the same fuel as a car with a perfectly efficient 4 cylinder.
It wasn't uncommon before all of this direct injection tech, for the car models with bigger and smaller engine options, for the cars with the bigger engines to actually be more fuel efficient.
glizzytwister@reddit
Dude, there's zero evidence to back his claim. Absolutely none. C6 Corvettes get 20-25mph at 75mph.
MyName_isntEarl@reddit
And yet, we have multiple people with personal experience giving very similar numbers.
I was very shocked when I made a 3 hour trip, trying to be nice to the car thinking it was going to kill me on gas to realize I was absolutely doing better than 30mpg.
glizzytwister@reddit
No, you have three people who are completely full of shit.
MyName_isntEarl@reddit
It's not fake.
Why would very aerodynamic cars with modern, well tuned EFI engines, with a drivetrain that involves a double overdrive transmission and tall rear end gearing, all on low resistance tires NOT get good mileage?
They are more aerodynamic than your car. Weigh about the same. It takes no extra fuel to push that car through the air just because it has a bigger engine.
I think you don't understand how big an effect drag can make... Or the rest of a car, honestly.
My car now DOESN'T get the mileage it once did because of engine tuning and internal/external parts. But, it's still 25+ mpg.
I literally rest my big toe on the gas to do highway speeds. It's super easy to not realize I've accelerated 20+ mph above my cruise speed because of how little throttle it takes to do that. And in a sleek car like that, you don't notice the change in speed.
Drag goes up in a coefficient. The faster you go, the greater little changes in drag take effect. Once you get in to 70mph territory it really starts to add up.
Years ago some airplane dudes took a regular airplane, did some speed calibrations, landed, quickly washed and waxed/polished it, then did the test over again, adjusted for changes in atmospheric conditions and it gained a few mph. Adding things like a smooth fairing between the wings and fuselage can pick up 10mph+ on a 120mph airplane. Adding those wheel covers over the wheels can add noticeable speed.
Apply that to a car, and it's the same speed.
There is a book on aerodynamics geared towards guys building airplanes in their garages called "speed with efficiency." That's how to get more speed with cleaning up the air, not adding more power... wait, what do you get with more speed and not needing more power? Well, you get more efficient! In airplanes that is rated at fuel burn per hour. For us on land it's distance per fuel.
No, I'm not lying, and neither are these other owners. It's common sense physics dude.
glizzytwister@reddit
So, no real world evidence, then?
Yeah, I thought so.
MyName_isntEarl@reddit
Multiple people here HAVE gotten that mileage. I didn't believe it myself, that I was in the 30 to 35mpg range when nicely cruising on the highway. There was no in town driving on that trip.
It's a very simple concept here, dude.
Take 2 cars of the exact same mass, exact same drivetrain. Shape one to cut through the air. And shape another like a brick. One will be more efficient than the other. The only difference is the shape.
A quick good example is this here: I looked up a 2015 caravan and a 2015 wrangler. Both use the same engine, very different shapes. The city MPG is stated to be the same. But on the highway the van has better mpg... It's almost like all of the things I'm saying are REAL.
Just because it's a v-8 doesn't mean it guzzles gas. If I have two of the exact same cars, one with a small engine and one with a big engine, and have them travel at the same speed, its going to take the same amount of energy to move those cars. Energy is fuel. They will require the same amount of air flow into the engine to burn that fuel. The difference is that the larger engine will have to run less RPM for the same volume of air, and the little engine will run a higher RPM for the same power.
If you can't understand this, you need to go learn a few things about aerodynamics, resistance, and thermodynamics.
glizzytwister@reddit
No, they haven't. No one is getting 38mpg in a stock C6, lol. A C6 getting 38mpg in 2005 would have been international news. It would have literally been the main selling point of the car. Toyota would have been shook. The entire auto industry would have been turned upside down overnight. Hypermilers would be driving Corvettes.
Listen, dude, I understand how aerodynamics and transmission ratios work, but that doesn't change the fact that this is impossible. In testing, they hit 25mpg tops, and around 20 at 75mph.
What you are claiming is ridiculous.
MyName_isntEarl@reddit
I never said 38.
I personally saw better than 30 in my own ls1 powered car. Yes, I was TRYING to get the best mileage possible when I did it. And you have multiple others in here with similar cars claiming to get high 20s to mid/low 30s. No, I don't know exactly 100% what my mpg was, but I do know when I filled up it was extremely close to what our 05 civic got on the same trip. I certainly didn't expect it.
Also, I already mentioned drag increases at such a rate with speed... You're not going to teach me anything I don't already know about fluid dynamics.
Unless you're an aerospace or automotive engineer, you likely don't have more knowledge than I do about this stuff.
A sleek car WILL get better mileage than a van or a jeep with an engine tuned for economy.
I'll never see that mileage again because of my internal engine upgrades and the tuning required to run it.
glizzytwister@reddit
Once again, no.
That dude claimed 35-38, and he's full of shit.
glizzytwister@reddit
Ok, now show me any evidence of that car getting that mileage at that speed.
RIP_Soulja_Slim@reddit
The Covette weighs less than the corolla, has taller gearing, and a much better drag coefficient. Obvs it's overall MPG isn't great, but vettes are known to have great highway MPG for a reason.
glizzytwister@reddit
At 75, C6 Corvettes get a max of 25mpg, and that's with a tail wind. This isn't debatable, he's not getting 35-38mph, not even close.
RIP_Soulja_Slim@reddit
Just making something up and saying "this isn't debatable" doesn't make you right lol. There's mountains of evidence of Corvettes getting low 30s on the highway, it's not unreasonable to think that under the right atmospheric conditions one could do better.

Is that a base LS3 in Florida? I haven't seen much above 30mpg in my grand sport on long interstate drives. But it's my fun car so I have averaged 11 mpg in 3500 miles.
ThrowAndHit@reddit
‘06 LS2. You had to baby it, but was definitely possible.
Kaylee-X@reddit
Highest I ever got was 36 over 100 miles and that was doing extreme hypermiling. Meaning I stayed at around 65mph and was very gentle on the throttle to the point where all traffic was driving around me. It was also 114 outside so that probably helped. Driving at 75 is more like 28-30 on mine. The instant you hit stop and go traffic it's more like 25.... city is 19-20.
Commercial-Ad90@reddit
My 1995 bro I averaged 12 MPG
Bran402@reddit
My 2017 civic got on average 35mpg and wasn’t even a hybrid.
mowleyyy@reddit
Not surprising to me but perhaps to some people, my rather large 25 year old peugeot sedan can easily get 47 mpg if I don't drive it like an idiot (it's a 4 cylinder turbo common rail diesel)
thumpetto007@reddit
some euro peugeot manual turbo diesels have the highest mpg of any ICE car on the planet. People get 90mpg fully loaded passengers and cargo.
xqk13@reddit
Are you sure those are US mpg? Because the UK mpg is significantly higher when converted from US mpg
masterventris@reddit
My first car was a 207, manual with the 1.6 turbo diesel, and it would return north of 65mpg without thinking about it. Who knows what would be possible if it was hypermiled.
Worth noting that any mpg figures for Peugeots will likely be in UK mpg which are bigger gallons.
FrenchyMcfrog@reddit
Old psa diesels are a cheat code when it comes to fuel economy, bonus point is they are bulletproof. Downside is they sound like tractors (the older na diesel that is)
0992673@reddit
I have an Xantia 1.9TD with the XUD9TE. 7.5l/100 city. 5l at 90kmh, 6l at 120kmh.
FrenchyMcfrog@reddit
Perfection.
Elvis1404@reddit
Is it 5 or 6 speed?if it's a 5 speed, with a 6th gear and cruise control you could probably go near 60mpg, diesels are crazy efficient
mowleyyy@reddit
Yes unfortunately it's a 5 speed and yes at 130km/h it's crusing at 3000 rpm lol
dev1anter@reddit
You sure it’s common rail?…
mowleyyy@reddit
Yes. Peugeot's designation for it is HDI (High Pressure Direct Injection), it's written on the back of my car
gumol@reddit
UK gallons or US gallons?
mowleyyy@reddit
US
TappedOut182@reddit
My C5 would do 32-35 MPG on the highway easily.
Around town it was probably 20 MPG, but anytime I could get it into 6th gear it was very fuel efficient.
cam-@reddit
Yeh all the vettes I have owned were like that, probably the best example was I got 40+ mpg from the C7 Corvette when road tripping to San Diego. I used o drive the C5 from VA to NJ for work once a month because it was comfortable and fuel efficient.
RIP_Soulja_Slim@reddit
I guess it's very unexpected among people who aren't familiar with em but yeah the Corvettes all have a reputation for being really fuel efficient on the highway. They've got a super low drag coefficient and a crazy tall 6th gear. IIRC the C5 used to cruise at 75mph at like sub 2k rpm lol.
maveric101@reddit
My C6 with the LS3 and TR6060 does about 1200 rpm at 60 mph... so that's like 1500 rpm for 75 mph, lol.
MyName_isntEarl@reddit
My 3rd gen Trans Am had the best drag coefficient of any production GM car at the time, I believe.
With an ls1 and a 6 speed t56 and the tall rear gear I have, at 75mph I was at 1800 or 1900 rpm. Foot is barely resting on the gas. It was just as good on the highway as my gf's civic.
MadamPardone@reddit
Unless you LS swapped a 3rd Gen, wouldn't that be a 4th generation?
MyName_isntEarl@reddit
It is an LS swapped 3rd gen
MadamPardone@reddit
Super cool man. LS swap the world! The T56 really allows the LS1 to shine.
diamondpredator@reddit
Yes, my C5Z did exactly that. IIRC it was at 1800 RPM at 75mph.
It was also surprisingly comfortable on long drives.
ZachtoseIntolerant@reddit
pedantic: it’s not just the 6th gear ratio it’s the final drive ratio too.
dog_in_da_park@reddit
C7 has a 7th gear, and Eco mode where it can run in 4 cylinders. I used to get 33+ on road trips. Leave eco mode off in town though.

Yeah, my built up C6 gets around 27mpg cruising @ 75mph. They're not nearly as bad as people think, if anything they get better mileage than the tuned JDM stuff I've previously had.
Seymour_Tamzarian@reddit
Another C5 owner here with similar results.
The other car that surprised me was my B9.5 S5, I get 28-30mpg on the highway thanks to 8sp trans, the car just coasts at ~1.5krpm at 60mph.
2AXP21@reddit
Just picked up a 2025 S5 and was surprised by how low it coasts, beautiful exhaust note too
Imaginary_Act_3956@reddit
Is the diesel version of the Citroën C5 not sold in your country?
Why y'all getting 30 mpg?
Do you only get the 1.2 PureTech and the 1.6 THP?
stoned-autistic-dude@reddit
Yeah, we never got that car. They mean the C5 Vette. C5/6/7/8 usually means the Vette in online discussions with a large U.S. userbase. Rarely do people refer to Audi chassis online with C# but if they do, they usually clarify Audi. I’ve never heard of a Citroen C5.
Beeblebrox237@reddit
They're referring to the C5 Corvette. Most Americans have never even heard of a Citroen C5.
Deathcube18@reddit
Don’t ever assume someone is talking about an Audi when referring to the „C“ platform. It is always a corvette.
The_Ostrich_you_want@reddit
Corvettes are wildly efficient at freeway speeds for the type of power they make. C5/c6s have gotten cheap enough that I’ve considered making one my daily.
TappedOut182@reddit
I would go C6 over C5 just due to parts availability. There are a number of parts (especially early C5) that are NLA that may not make the car undrivable, but make it a pain to live with.
LightlySaltedPeanuts@reddit
Is that with 93 octane?
TappedOut182@reddit
Yes, I only ran 93 in it. I don’t recall if you could drop the octane down but it was an occasional use car so the cost differential wasn’t a big deal.
AudioPi@reddit
I had a Trans Am WS6, so basically an overweight C5, and I had the same experience. Cruising at freeway speeds (~75mph) and it was basically at a high idle in that overdrive 6th gear. Literally maybe 1100 RPM
MyName_isntEarl@reddit
I have a 3rd gen trans am with a C5 LS1 and a T56 in it.
Highway speeds I'm hardly touching the throttle. It was absolutely amazing on fuel considering the performance it had... Just don't use that performance, or your fuel usage goes way up.
It's not as good now with the cam I have in it, and the overly rich tune isn't helping (need to get another one done)
Doubleoh9@reddit
My 2005 C6 was the same, you had to be going 92 to hit 2000 rpm in 6th gear so it just idled down the highway
diamondpredator@reddit
Wow that's even better than the C5's 6th gear. I think my C5Z06 was at 1800rpm around 75mph. But yea basically just hovering above idle on long trips. It was awesome.
diamondpredator@reddit
Came here to say the same thing. Mine was a Z06 so slightly less efficient but I would get 30-32mpg on the highway and around 18 in the city. I do have a bit of a heavy foot though so if I grannied it a bit I'm sure I could've squeezed more out of it.
It was awesome cruising in 6th at 75+ and under 2k rpm haha. With how aerodynamic the car was it was effortless.
Smykster@reddit
Came in here to say C5 as well. Easy 30’s on highway.

TappedOut182@reddit
Corvette C5, sorry for not being super clear in the OP.
TeamJim@reddit
Same thing in my 4th gen Z28. 0.50:1 6th gear and factory 3.42s meant highway speeds were less than 1500 rpm and it made enough torque to barely be touching the throttle to maintain speed.
Even now with a pretty healthy 370 inch motor and 4.11 gears it still gets mid 20s cruising.
PotatoDrives@reddit
I had a third gen Camaro like that. 5th gear it would just basically idle down the highway.

1991 Toyota Corolla with a 1.6L baby engine. It's slow when accelerating but so reliable and helps me save money on gas monthly. I only spend $20 when I'm 1 line from empty. I've been modifying it but the engine is still the original.

My B9 A5 Sportback gets high 30s on the highway, some people have reported high as mod 50s on the highway.
Of course if you drive it hard, can easily get below 20.
briansmith@reddit
What tires are you running? I found that the original Pirellis had about 3 mpg better fuel economy than my Conti DWS06s give, but I hated everything else about those tires.
6786_007@reddit
Continental DSW06+ so far so good, big fan of them. The previous tires that were installed were garbage. I would slide badly in the rain and they were loud. It's likely those Pirellis were harder tires which got better MPG but it's gonna suffer in performance and noise.
Bourbon_Buckeye@reddit
Similar with my 2022 BMW 430– I regularly average 40+ mpg on my highway commute. BMW sends a monthly report— I averaged 38.2 mpg in August.
6786_007@reddit
Yeah that's really good. Mine has Quattro too so its even more impressive IMO. The B9.5 are slightly better with their Ultra system, but its also basically fwd.
Bourbon_Buckeye@reddit
Yeah, the drivetrain makes a difference. My 430 is RWD. My son drives the older AWD 3-series and it averages about 32mpg
6786_007@reddit
How's the b48 been? Really thinking of goijg bmw next but the 530/540.
Bourbon_Buckeye@reddit
I love it — I don't need big power. It's over 76k miles now—the engine has been great, but I did just recently had to replace the rear diff ($$$!).
I'm considering trading-in the 4 for an X3 and have no qualms going with the B48 again. If I was shopping for a 5-series, I'd probably spring for the B58 since they sell pretty cheap off-lease.
My 3-series is older (2016) and has the hated N26, but I've had luck with it. It's not as smooth as the B48, but the car has 160k miles and still runs strong—never a major repair needed.
6786_007@reddit
Nice. X3 is nice as well, not too big on the new generation though. What happened to the diff?
Bourbon_Buckeye@reddit
Yeah, hate the latest X3 too. I'm not afraid of used though.
The previous owner ran the rear diff low on fluid for a long time. I didn't notice it leaked until I did my first fluid change on it and the diff fluid was super low. I topped it off, and started noticing the drips in my garage... got worse and worse and the diff got noisier. If the previous owner had repaired the seals when they first noticed the leak, the diff probably would've been fine. IDK if they just let it leak until it got low enough that they didn't notice it anymore and thought it fixed itself?
6786_007@reddit
Way too many people ignore simple things like drips and let it turn into a huge issue and then blame the car.
Thats sucks. But its reassuring it wasnt the car but the previous owners laziness/neglect.
Captain_Mazhar@reddit
Is that the B48 with the mild hybrid version? I’ve been looking at a 3 series for a while with that engine and it looks sweet.
Bourbon_Buckeye@reddit
Nope, just the base 430. I just drive a lot of easygoing 60mph speed limit highway miles.
Seymour_Tamzarian@reddit
Agreed, I just posted in a comment above that I was surprised to get around 30mpg is my B9.5 S5 sport back.
ctt713@reddit
Our b9.5 a4 45tfsi gets 35-38mpg on the highway at 80. At least that’s what the gauge cluster reports. I think actual may be closer to 33-35mpg but with a 15 gallon tank we can easily go 450+ miles in between fill ups.
_eg0_@reddit
My B9.5 S4 Avant can do 67mpg(US) or more realistically 50mpg(US) if we exclude short trip and a lead foot. You can say a lot about how controversial the change to the EA897evo2/3 was but it did its job.

I work from home now, so it really doesn't matter anymore, but if I was still commuting, I'd pick up a hybrid front wheel drive boring as hell to drive kinda of car.
No_Echo_1826@reddit
Nice series of cars there, I think you've been through more Subis than I have cars in 18 years by one, lol. I just got an '11 STI and I was seeing if it was the same, but I'd say if it was it'd be an exception to the rule at this point. I'm about 5 thousand miles out from the timing belt change and I'm not looking forward to that one. Just got the spark plugs done though, they were overdue for sure.

The BMW Supra yeah, the mk 4, my god, no. I even had a car with the non turbo 2jz-ge that had absolutely abysmal fuel mileage, like 18mpg with only maybe 1/3 city driving, and it was relatively slow. Can't even imagine the gte.
AromaticWhiskey@reddit
Was about to say, that's kinda mediocre for a Supra until I saw MT in your flair. If I revert back to stock map, I've seen as high as 41mpg when just cruising at 70mph and letting the ZF8 do it's thing. Otherwise on stock map, 36~ @ 75mph is about average.
Tuned, 32-34 @ 75.
shouldahadaflat4@reddit
Wow that's super impressive. Makes sense given the light weight, ZF 8 and B58 combo. I've averaged 24.4 mpg over the life of my supra (3k miles) but when I drive it I drive it hard, so the fuel economy is still pretty impressive to me.
I basically hyper mile my WRX and only get 27 mpg.
RIP_Soulja_Slim@reddit
Almost all of BMW's B58 cars have better gas mileage than you'd expect given the amount of power it can put down on a whim. It's a seriously impressive engine/trans combo.
AromaticWhiskey@reddit
The super tall 8th gear, 3.15 final drive (vs 3.46 in the MT), light weight (relatively) and the drag coefficient all adds up to it being 4 cyl level of fuel economy when it's just cruising on the freeway. 8th @ 80mph is like 2100~ rpm, and 70mph is like 1800~ lmao...
Doesn't really change that much when you can hit near 500wtq at like 2200 rpm on pump gas with a downpipe and an OTS tune.

B58 is amazingly efficient. Just got 38 MPG on a 10 hr road trip through the mountains in my 540i.
HonorableChairman@reddit
I wonder how much of that comes down to the transmission. My 540xi can also do mid 30s highway, which was such a stark difference coming from an E90 with the six speed auto. That thing struggled to get more than 25 mpg with like a hundred fewer horsepower haha.

RIP_Soulja_Slim@reddit
That engine had all sorts of problems, but not tied to cylinder deactivation as an idea. GM has been doing that reliably (well, reliably for GM) for 20+ years.
autisticlettuce@reddit
Oh dang. The dealer that did the repair said the lifters were tied to the deactivation stuff. My bad!
mastawyrm@reddit
Yeah the dod problems have been around since the beginning which is why, I thought, that gm v8s were the best known version of it. I've replaced the pictures with normal ones on my Gen 4 6.2 but I've heard the gen5 is even worse somehow. Wild that they didn't figure it out or at least improve on the new engines. At least the hd trucks offer the 6.6 without dod
RIP_Soulja_Slim@reddit
Yeah, they had it on the old 5.3 v8s going all the way back to the early 00s, maybe even before? I know my friend's parents had a trailblazer that did it back then.

I got a 18' wrx sti that's telling me it gets 40.3 mpg average on trip a which has thousands of miles calculates into it. If I reset to get new numbers on trip b depending on my driving I can get 45 to 50 on there. But do I believe it? Hell no! Lol
TheDirtDude117@reddit
So it's probably not surprising to all but my 5000+ lb 300hp/500tq V6 AWD Touareg that regularly tows over 8000 lbs gets 35 mpg highway often while driving without a load and mid 20's when towing my C5 Corvette.
It's a diesel & has an 8 Speed Auto from a LX570 / Cayenne Turbo so it's stout. Rocking 255/40R20 Michelin Pilot Super Sports on it though makes the numbers more crazy but they were free new tires.

I recently bought an 06 Camry, immediately deleted the balance shaft assembly, and have been averaging 36-37mpg. I know that may not be surprising to you...but I didnt research the fuel economy before I bought it and just assumed it would probably be in the low 30s, the high 30s for a mid-sized with a fairly large engine (2.4 liter is big for a 4 cyl IMO). But I deleted 30 pounds of unbalanced, rotating mass directly parasiting from the crankshaft so that may be cheating. But I bought it about 5 hours away from where I live and averaged 34 on way home (it has an mpg display)...but again I was still kinda surprised. Never expected these things to get over 32.

I had that pickup as well. It didn’t come with a rear bumper. A key and a heater. Paid a tick under five grand for my 1992, new, thanks to Costco.

2022 Hyundai Elantra: 46 mpg. This was a base model Elantra, not the hybrid. If the regular car is that fuel efficient, then what's the point of the hybrid?

Diesel makes sense. I wonder if the overall operating cost with DEF and regular oil changes is still cheaper.

Def is like $9/box and I use it sparingly when I'm not towing. If I'm towing it's a box every tank pretty much.
Oil services are 180ish bucks.

Commented elsewhere, but my 2000 F-350 7.3L (that was the diesel back then), CC LB 4x4, got 20MPG on a 750 mile trip along the west coast. At the time that seemed insanely good.
23-25 is fantastic. Is that with the 6.7L or the 6.8L?

Individual throttle body, 12.5:1 cr, bored out, ported and polished, DOHC with huge cams, all motor Dodge Neon ACR with a 4.12 fd and quaife LSD. Long tubes, weight reduction, carbon panels, insane suspension and brakes, etc.
Made 235 whp in a 2200 lb autocross/road course machine with all appropriate supporting mods. I could get 45 mpg on the freeway at 3800 rpm. That was the sweet spot for volumetric efficiency for that build. Under that rpm, and it got high 30 mpg. Over that rpm, and it dropped off rapidly. At redline, 9600 rpm, it got like 11mpg.
When it was stock 100whp SOHC with a 3.55 fd open diff, full weight, and a 6800 rpm redline, it got 34 mpg, tops.
Raced it in SCCA SM, then SMF when it came along and usually was top two, only getting beat by awd 400 plus whp STI or Lancers. Anything under 400whp would get walked by it. Usually top 12 PAX too, but the first 10 spots were national champ Lotus Elise, the national champ X class miata, a couple of A mod chassis cars with pikes peak sized wings, a shifter cart who usually went top three at nationals, and surprisingly a highly modded M3 E36.

I had a 2018 Mazda3 with the 2.5 and a 6MT and despite the window sticker claiming 25 mpg city and 32 highway, I had to beat it like it owed me money to get less than 27 in town. On the highway it would easily do 37-38 mpg and if you coddled it, low to mid-40s were not impossible.

My sibling's CLA 45 AMG will do 6.5L/100km in steady state legal 100km/h all day on the freeway. Granted it is a 2.0L I4 turbo, but still pretty amusing since this 375hp rocket can get this kind of mileage. In comparison a WRX with 271hp would struggle to better 10L/100km...

I used to own a 2012 Audi A6 Quattro 3.0TFSI which despite a 19city/28hwy EPA rating would easily outperform that estimate. I would see ~30mpg at 80mph and 34-35mpg at 70mph, Short trips and drive-throughs annihilated fuel economy as it was thirsty at idle though my average was 26.5mpg by the time I replaced it with my current car.
Speaking of.. it doesn't use gasoline but the EPA-city rating for this car of 110MPGe (3.3mi/kWh) is laughably conservative because I easily see 4-5mi/kWh (135-168MPGe) driving it in the city.

My old C5 Z06 got anywhere from 30-35 mpg on the freeway in 6th gear around 75mph.
City was about 18-20mpg due to my lead foot.
Car was light AF from the factory which included a carbon fiber hood. Coupled with the long final gear made for a very nice freeway tripper across the states.

I don't know about unexpected, but my fairly heavily modified 2002 WRX was averaging 27MPG.

To be fair, you'd be getting 25-27 dead stock too. Thats the more impressive thing with turbo Subarus, the mpg doesn't really change unless they're insanely modded.

True. I've been toying around with the idea of getting a VA for a daily so I'd have AWD during the winter commute, but I don't think I can give up the 38MPG my Civic gets... I'd be filling up twice a week.
carmeiser@reddit
Arent the VAs not as bad as the EJ powered cars? Like maybe 30-31 at best, but still. I can see why 38 mpg is in your favor. The Corolla Hybrid appears to have AWD, a coworker got a fwd one as a rental and loved it. It got 50 mpg without trying too.

My Accord sure surprised me. My best ever was 38 mpg on a trip doing \~65 mph, and at 80 mph, I can consistently do 32 - 34 mpg. Not bad for a relatively big V6 making good power.
City mileage isn't great so it evens out, but the highway mileage is fantastic. Crushes the four cylinder trims of that era.

Probably not unexpected but the EPA drastically underrated the CR-Z's potential gas mileage. I've regularly gotten 50+MPG (US).
daxelkurtz@reddit
When I was a park ranger, my base '16 Civic was my work vehicle. About half my driving was off-pavement - sometimes roaring along, sometimes going below walking speeds to dodge rocks and sinkholes. And the driving I did on pavement was generally incorrigible. I basically can't think of a worse recipe for fuel economy.
Still couldn't get it below 34MPG.

35 mpg. At $3.50/gal it costs $0.10 per mile in fuel.
R-rated tires cost $250 each ($1,000 for a full set) and have a rated life of 7,000 miles, so it costs $0.14 per mile in tires. Oh, and 7k miles is being generous; one full track day will burn up a quarter of the tread life.
The car’s tires cost more per mile than gas. And not by a small amount!

Went 410 km on a bit under 16L of fuel in my wife's 2018 Golf SportWagen on a roadtrip once, when we hit the first pit stop (60mpg?). Very slight tailwind for parts, but the drive was from Calgary to Saskatoon, so also gradual elevation change (to a lower elevation) and IIRC a chunk of the route was on secondary highways, which have a speed limit of 80 kph (89-94 actual) instead of the usual 110 (119-124 actual), which woulda really helped.
Was on the winter tires though, which you'd expect worse fuel economy with

Gasoline engines are most efficient when running at near maximum load, so assuming everything else being equal, a smaller engine working harder is more efficient than a more powerful one that doesn’t have to work as hard.
FSCK_Fascists@reddit
not necessarily. That can be very efficient if you drive it to be. Slow and steady instead of trying to run a Nascar lap. Most are impatient and want max acceleration. pedal to the floor is seldom efficient.

Early 80's Honda Civic, 1.3 L engine. It already had great gas mileage stock but for a while and just for fun, I tried some very basic techniques for increasing gas mileage such as driving with a VERY light foot.
I topped 50 mpg in CITY driving. (Imperial gallons because of where I lived at the time.)
I did not end up pursuing this gas-saving measure because its normal gas mileage was already so good.
I ended up flogging it like the proverbial rented mule on the daily because it was fun to do and because while flogged, it STILL got good gas mileage!

Two:
2022 Pacifica its rated at I think 27 on the highway but if you keep it under 80 and it isn't too windy, it'll get a little over that. On a 2 lane highway around 65, especially if there are lots of trees on the sides of the road to slow down wind, it'll do mid 30s.
2006 Grand Prix GXP: I know AFM/DOD has had problems but mine never did. If you could get it just right where it'd stay in cylidner shutdown mode on the highway, it'd get 28-29. Not bad for a 5.3L engine and 4 speed auto. You'd sometimes have to speed up or slow down a little to get just the right amount of load on the engine per the RPM, and oddly enough going slightly faster sometimes would be better because the engine could tolerate the shutdown with the RPM up a little more. You'd actually get better mileage going 5-6 MPH faster in some cases because of that.

Mixed interstate (75mph) and highway (60mph) I'll consistently pull over 30mpg hand calculated - and that's with at least one regen.
If I stick to the highway for my work commute instead, I'll flirt with 34mpg. Diesel is cheaper than 87 octane where I live as well, so that's an added bonus.
Full size 4x4 truck that outperforms my spouse's non-turbo CX-5 in terms of fuel economy. Blows my mind.

My Ford Escape PHEV gets about 41-45 mpg (ignoring recharging the battery). This is only "unexpected" because a) no one on this sub ever mentions the Escape since it's a pretty invisible crossover and b) this is probably the first car I've ever owned that meets or exceeds its official gas mileage.
Random trivia: the Escape PHEV is possibly the only PHEV (available in the US) that gets better ICE mileage than its non-PHEV hybrid counterpart.

I used to have a Skoda 2.0TDI gives around 24kmpl in highway at 80-90 kmph or 50-55 mph ( 57.3 US mpg / 68.8 UK mpg ) Was pretty efficient
Perpedualmotion@reddit
While overall it wasn't crazy impressive, my '98 E36 M3 would regularly get 28 mpg cruising near the speed limit on the highway. BUT - on December 31st, 1999 I had a ticket to see Jimmy Buffet's Y2K show at Universal Amphitheater. I left the SF Area East Bay just after Noon with a full tank of gas. I-580 out to I-5 South, traffic was amazingly light. I averaged 94 mph (including getting through surface streets in Hayward to I-580) and got 26 mpg for a 297 mile drive in about 3:10. That car was pretty amazing, wish I hadn't sold it.

Interestingly enough I had my best and worst fuel efficiency on the same car!
My Subaru STI would get 28-30 mpg on the highway if I was just cruising and staying out of boost...and then I modified it lmao.

My 2000 F-350 Crewcab, 4WD, Long Bed. 7.3L Diesel. If I drove the highway speed limit I could get a legitimate 20MPG. As an experiment I once drove 750 miles from the bay area to a bit West of Portland, flled up with exactly 37.5 gallons afterward.
Sure, 20MPG isn't efficient compared to many, but for a 7500 pound pickup truck it sure seemed pretty good.

I had a '94 BMW 325i. Best car I ever owned. That thing loved speed, and got 40 mpg sometimes on a road trip. But only if you were going over 80. Keep it reasonable and it got 35 ish...

My 1996 BMW 750iL (with the 5.4L V12) gets about 21 mpg combined. Obviously not amazing but with 12 cylinders I was expecting about half that honestly. Hypermiling it on the highway, coasting as much as possible, with downhills, I've gotten it to 28 mpg!
OldSquid-71@reddit
I know it's technically an econobox and is supposed to get good mileage, but my 2014 Elantra got a hair over 42 MPG when I ran 2 tanks of ethanol free gas through it (back to back). It averaged low to mid 30's with 10% ethanol any other time. And it was a shitty horrible car in pretty much every other aspect.
I've since done similar gas comparisons with my other cars, and none have had that much of an improvement using ethanol free.

2016 Civic EX-L, I bought it hoping to get 37 mpg but ended up averaging more like 42 mpg, once even got 46 for a while tank. Bought an Insight a few years later and was disappointed I couldn't stretch the fuel economy that far over the EPA rating, even though it was even more fuel efficient

My current daily, a 2013 BMW 335i xDrive manual. When I first got it I was averaging 26 mpg with about 60/40 in town / highway. It got low 30s highway using hypermiling tricks. It actually went up a little with the basic mods, tune, catless downpipe, intercooler and charge pipe. Even after going bigger turbo and the mods to support it I'm still averaging about 23, which isnt bad for a 490 awhp 3600 lb AWD sedan rolling on super wide sticky tires.

Back when it still had the factory 2.73 rear end and I was still making more longer distance drives in it, my Mustang routinely got 28 MPG at 75mph on the highway. I hit 30 on one tank where the traffic gods shined their light on me and I was able to cruise for a full tank on the interstate with no stops and hardly any times where I even had to slow down and cancel the cruise control.
City was still 15~18 depending on various factors but a V8 with tall gears and a deep overdrive barely turning any RPMs in a car with, like, a quarter the frontal area of a pickup truck can get surprisingly good highway MPGs, and it’s always hilarious to hear how hilariously bad a lot of the smaller engined sports cars are when they’re having to turn 3500 rpm at speed to get the gearing low enough to be peppy off the line.

For context, a 2024 Toyota 4Runner 4WD with the same powertrain and frame is EPA rated at about 16 city 19 highway. I don’t get it. Maybe they changed the rear axle ratio, or re-tuned the engine to run less lean?
