Doesn't the RX-8 have a 4-cylinder rotary engine? I read a review that said despite producing high output for the engine it kills the gas mileage. I think it was like 18-19 mpg. For a little car like that I would expect more. I have always liked the looks of the RX8 however, though it could probably due to lose the back seat--but in a pinch I guess it would do the job.
