They're planning to use a 1.4L (turbo?) gasoline inline-4 engine as the generator last I heard. That was the death of it for me. Even in a super-lean-green-atkinson-cycle burning machine fashion I can't imagine it getting much better than 100 mpg out of it on gasoline alone. If they'd used something like a 600cc turbo engine, then I may have been more receptive.
Even the VW 1L car used a diesel engine, minimal weight and a 1+1 seating configuration to get the aero to work.
Ah - 230 mpg in city driving WITH charging at home every night. Yeah, that's kind of like saying, "I get 100 mpg in my Civic.
On downhills..."
