Re: I like this VW four-seater..
Cool. Fuel cell cars don't even consume gasoline, so the mpg might not be important. That is unless the hydrogen comes from fossil fuels. But yeah, it has 4-passenger capacity, which hasn't been done with a Supermileage car.
Instead of starting with a massively expensive fully loaded SUV and trying to subtract things to get better economy, they should start with a hydrogen-burning VW One-Liter car, together with a home solar-hydrogen refuelling system. Then they should ADD stuff to it, while trying to maintain the fundamental home-refuel capability.
