Kalio

From what I saw the motor was still mid-mounted, it was just further up than most other cars, making it probably closer to true center on the car. Still, very cool car.

My suggestion/idea was based on real cars, with the rear wheels being powered by an engine in front of or over the front axle. As someone else mentioned though, not all full size car dynamics scale down to RC cars. I think such an RC car would still be interesting to see though.
