Other than the acceleration and gradability requirements I dont think they are unreasonable. 10 cubic feet is 2x2x2 +1x1x2 worth of space, hardly a lot of room. If you have a good aero design, you should be able to get 100 mph. The range is reasonable, any less and you have put a massive bias to electrics.
We proved 30 years ago we could get 1000mpg if we willing to accept a 1 person tin can that would only do 20 mph, the X prize is about building something that people would actually buy.
