Sort of. Fuel economy has been a major sales point of cars for decades. It's the main reason that cars are now slipperier than ever before.

I am not limited by these; I am limited by physics.

Not really. You'll be most limited by cost and what you can build.

The physics says that the drag coefficient, frontal area, weight, and engine are the four main variables I can work on minimizing. If I minimize the first three, then I can minimize the last one, and probably still have decent acceleration.

Sure - but a lot easier said than done.

How many miles per gallon did the VW XL1(?) achieve?

How many miles per gallon do you think the BOcruiser would get with an ICE with its 0.135 drag coefficient?
|
I have no idea! What engine? What transmission? etc

How difficult would it be to copy the BOcruiser? Maybe they'd send me the CAD files.

I thought safety was important?

I'm shooting for 100 mpg at 60 mph, in the long run. It'd be something if I achieved 60 mpg at 60 mph.

Those two different figures are light-years apart in diffculty!
