Just ran across this on Drivers' Republic. Obviously not M3-specific, but interesting. Nissan DeltaWing racer gets sideswiped by green Porsche GTC car, immediately flipping the DeltaWing. The driver ends up sliding on his head.
The DeltaWing is a new design that's supposed to revolutionize sports car racing with a lightweight, efficient platform. But seeing this makes me wonder about the inherent stability of the car. The extremely narrow front track, almost like an exaggerated top fuel dragster, would seem to make the car easy to tip over from a side impact. It's like a tricycle.
