The 2008 Rinspeed sQuba the world's first "real" submersible car, capable of driving on land, floating on water, and diving up to 10 metres (33 feet) deep.

Unveiled by the Swiss automotive firm Rinspeed at the 2008 Geneva Motor Show, it was directly inspired by the submersible Lotus Esprit seen in the James Bond film The Spy Who Loved Me.
The sQuba is built on a Lotus Elise chassis and utilizes a zero-emission electric powertrain. Unlike military amphibious vehicles that crawl along the bottom, the sQuba "flies" through the water using propellers and jet drives
It uses three electric motors: one for land travel and two dedicated to underwater screws and Seabob jet drives for steering and lift.
For safety, the car is a convertible. This allows occupants to escape easily in an emergency and avoids the massive weight (roughly two tons) that would be required to counteract the buoyancy of a sealed cabin.
Since the cockpit is open to the water, the driver and passenger breathe through an integrated scuba system with on-board compressed air tanks and regulators.
It features a laser-guided sensor system for autonomous operation on land.
The interior is entirely salt-water resistant, featuring non-slip diamond-plated inlays and mother-of-pearl trim.
While a fully functional prototype exists, the sQuba never entered mass production. The single existing unit cost approximately $1.5 million to build.
In recent years, Rinspeed has released a 3D NFT version of the car as part of its explorations into the Metaverse.

And would later be redesigned into finn mcmissle for cars 2.

The open cockpit was a surprise
rotorain@reddit
The description makes a good point about needing 2 extra tons of weight to counteract the buoyancy from having air in the cabin. There's not really a good way to add that much weight to a lotus and would ruin the drivability on land.
xrelaht@reddit
Do it like a submarine: ballast tanks that take on water while you compress the air which takes up that space on land.
rotorain@reddit
Submarines still have enough weight to offset the buoyancy of the interior volume of air. They use compressed air and water tanks to adjust a little above or below neutral buoyancy. Water weighs nothing in water because it's the same density, you need something way heavier than water to offset air being way less dense than water.
Namenloser23@reddit
It's also the safer option (and likely the only feasible one). Even a normal car door is way too complex of a shape to reliably seal, especially if you take into account wear and body flex.
MiraKyoshi@reddit
Speaking of safety, if your enclosed underwater car ends up breaking down, there's no way you're opening that door to escape until the cabin fills with water anyway.
Kichigai@reddit
Or just imagine if the vehicle malfunctions and you need to get out. You either need to have the strength of Hercules or wait until the cabin fills to open a car door in water. That's why they sell those emergency window smashers.
rotorain@reddit
They'd have to seal a lot more than just the doors too. All of the controls, steering wheel, pedals, wiring, buttons, floor, roof, etc would have to all somehow not leak any water. There's not really a feasible way to do that.
Kichigai@reddit
Well it's an EV, they gotta seal a lot of stuff anyway.
schizeckinosy@reddit
It’s the only way to go for performance, but it sure isn’t convenient lol
jimbowesterby@reddit
I mean, how often do you find yourself having to drive your car underwater? Convenience doesn’t really matter when it’s something you do just for fun
jimbowesterby@reddit
Not to mention trying to engineer a compartment like that into a Lotus, might as well just build the car from scratch at that point.
7ofalltrades@reddit
Yeah it totally makes sense in hindsight, but scrolling through the pics and they just drive into the water with the top down was wild.
sllewgh@reddit
Especially underwater...
Downside190@reddit
yeah I was expecting a roof up shot underwater not them just wearing diving gear inside the car lmao
jimbowesterby@reddit
Makes sense if you think about it, can you imagine how much harder it’d be to strengthen every inch of the cockpit to seal it? You’d basically be rebuilding the entire car and it’d probably add a huge amount of weight
Drzhivago138@reddit
Fitting that it's based on a Lotus.
lndianJoe@reddit
Seriously, how many cars were based on the Lotus Elise?
ChevroletKodiakC70@reddit
The original Tesla Roadster is the other i can think of
AhhYahBassa@reddit
Vauxhall vx220/Opel Speedstrer
jimbowesterby@reddit
Iirc there’ve been a bunch of small startups that’ve used the Elise as a base but I could be wrong. The type of company that makes a few super neat cars then goes out of business type of thing, like Weismann

Bond approved.
Paper-street-garage@reddit
I know the other guy dressed like him in there ha. Super cool it’s just too bad. It wasn’t enclosed like a submarine.
Whiteums@reddit
It said in the description that it was open to avoid the problems of too much buoyancy.
Paper-street-garage@reddit
Oh yeah, I thought of that right after I it would have to have some serious ballast weights.
No_Cook2983@reddit
Wouldn’t it be a better submarine if it had a roof?
TouchingTheMirror@reddit
It's like something you'd see in "Venture Twins."
justaBB6@reddit
not because of the Bond submarine, just because as a company they’re constantly underwater
Bigs38l@reddit
Kill the rich by making them go dive. Interesting.
Freak_Engineer@reddit
Kind of wanted one until I saw the interior...

god damn submarine Lotus? I'll take 2

That gauge pod is 100% Jetsons inspired and I love it.

The manual crank windows lmao
Dorwyn@reddit
Lotus hates any unnecessary weight. Their founder used the philosophy of "Add a pound of power and improve the speed. Reduce a pound of weight and improve everything else". So usually the lighter option is put in, luxury be damned.
JakBos23@reddit
Roll the windows up your messing up my hair.
Idiotwithaphone79@reddit
I am happy knowing it exists. Thanks OP.
Someth1ng_Went_Wr0ng@reddit
What could possibly go wrong?
TastelessDonut@reddit
Oh yea losing your mask while moving, strapped in a car and trying to find it while it’s behind your head underwater. No thanks.
JakBos23@reddit
If I lose my breather I'm just gonna swim up. I think it said rated for 33 feet. I can make it.
jimbowesterby@reddit
Honestly seems like way less of a death trap than being in a sealed compartment and trying to get out
JakBos23@reddit
Yeah when I saw the 1st pic I thought no thanks. Then I saw it was used with the top down and I thought ok now I want one. My auto shop teachers friend made a car that would float. Made some weird handle that made the doors seal. Anyway apparently in the 80s there was no law in KS that said you couldn't drive your car around in the river, but the police made it very clear to him that he has to call and tell 911 he's gonna do it before he did it again. I'm told the first time the cops impounded the car and arrested him for disorderly conduct and the judge laughed at that case. That's when they gave him rules lol.
PCRFan@reddit
The only actually interesting thing Rinspeed has done
DefinitelyNotAxlerod@reddit
-Show super ultra cool car
-Do nothing afterwards
-Repeat
jimbowesterby@reddit
Well they are a coachbuilder, their whole business is basically just fancy one-offs
jimbowesterby@reddit
I mean, have you seen any of their other cars? They’re one of the most consistently creative coachbuilders out there, miles ahead of any other company I know of. They even made a usable amphibious car that can manage normal boat speeds on water, I’ve only seen one other design that’s managed that.
Ryaktshun@reddit
I remember watching the YouTube video when it came out and I was blown away
jimbowesterby@reddit
Rinspeed’s probably my favourite car design company, they’re so reliably imaginative
gr8masturb8@reddit
interested to see how they seal the cabin watertig-
oh.
WolFlow2021@reddit
Feels like that premium hifi gadget you don't actually need and can't afford but really, really want.

What was the target group? Retired spys?
CanonicalbombXVR-626@reddit
I swear between this the old Bond Lotus and the Teslotus, there are a lot of gimmicks baked into Lotuses
kaest@reddit
Why did they Photoshop it instead of doing an actual shoot? Looks awkward af.
matroosoft@reddit
Reminds me of the Gibbs amphibious vehicles. One of my teachers had a poster of the Aquada which I still remember to this day. Amazed me that such a cool looking vehicle could both drive on land as well as on water.
humanstreetview@reddit
my ears hurt just looking at that picture
blacksun_redux@reddit
Last summer a person experienced in freediving told me the correct way to equalize ear pressure. I had always done it every 5 or 10 feet, but the correct way is to almost constantly equalize, every second or so. That way the pressure doesn't build up and the ears equalize easier. Within minutes I was diving deeper.
humanstreetview@reddit
I don't know what that means. I just know my ears start hurting near the bottom of the deep end.
blacksun_redux@reddit
As you dive underwater, pressure increases. This is because water is heavy, and the deep you go, the more water is "on top of you". The increasing pressure of the water against your eardrums can hurt. Equalizing ear pressure is done by holding your nose, keeping your mouth shut and "Blowing". You can try it right now but be gentle, some people have ears that don't do it easily. When you do this underwater, the pressure of the water equalizes with the pressure behind the eardrum allowing you to dive deeper without the ear pain. But if you don't do it constantly, like I mentioned, it becomes harder to make them "pop" because too much pressure has built up.
humanstreetview@reddit
yea I was joking about that first part thanks though

Remember seeing this thing on the Science Channel as a youngin & being absolutely dumbstruck by it

Another car based on the elise chassis! Was it that amazing that companies are still churning out new models 20 years later based on it?
GreatBallsOfFIRE@reddit
I think you might have missed the part where this was from 2008.

The Lotus Elise is the new Pontiac Fiero
Worldly_Possible2925@reddit
Terrifying you say ? Why I totally agree 👍🏻.
gregg2020@reddit
Man that lotus design has been my favourite since I was a kid, they really made the perfect car!
theknyte@reddit
That Lotus Elise chassis was something else.
Used by Lotus for the Elise, Exige, 2-Eleven, and 340R. Used as the basis for the Tesla Roadster. Used as the basis for the Vauxhall VX220. Used as the basis for the Hennessey Venom. And, who knows how many "one-offs" that have never seen the light of day were based around that little chassis that could?
Beaver_Squeezer77@reddit
It’s a cool car although I can’t help but think the folks who would buy it would need vigorous training to operate it properly. I have a vision of a couple getting ready to dive and thinking if they just turn the a/c to Max they will have all the air they need😂
