If Olympus Mons were on Earth, and if it didn't collapse under its own weight, could a wheeled vehicle drive the 230 mile distance up to the summit with an engine setup like the Grob Strato 2C assuming it somehow got past the initial cliffs? How much power is needed to maintain 60,000 feet vs drive on a 10% grade at 72,000 feet and can these engines produce that power at this altitude? How much fuel would it take? What size batteries if it were an EV? The drive back down also needs to be considered.
