I'm Just Sayin' #58

So supposedly this crazy whacko astronaut chick drove from Houston to Orlando wearing a diaper so she wouldn't have to stop? I wanna know what kinda car she drove, that can go 950 miles without a fillup.

950 miles (~1,500km) without stopping, hmm.

Assuming a really fuel-efficient (and for European, not US, values of) car, say 5lt/100km (47mpg), it would need 75lt (19 gallons) of fuel. Now the only problem is that cars that fuel-efficient tend to be rather tiny and need to be light, thus usually have 45lt tanks (sometimes upgradable to 55lt).

But ok, we Europeans can get even weirder, f'rex Volkswagen built the VW Lupo 3L, the "3L" meaning a fuel-consumption of 3lt/100km (diesel, of course, as that holds about 13 % more energy than regular petrol), which should be about 78mpg. The downside being that the tank only holds 32lt, with tricks you can get in up to 40 - still not possible to drive 950 miles with that, that'd need 45lt of (diesel) fuel.

There was even a prototype of a 1lt/100km car (IIRC also from Volkswagen), but it never made it into production because of the downsides (expensive, carries only a single person, and only reaches the 1lt/100km mark at a steady 90kph). And it had a, IIRC, 8 or 12lt tank.

So I say: bullshit, not doable. At least not in a standard vehicle.
