BMW X5 (E53) M Prototype 1999

[Humungus]

This was an E53 X5, fitted with the engine and gearbox from the E39 M5, and converted to rear wheel drive. The engine had some modifications done to it, resulting in about 440bhp. I don't know much about it's performance figures, but I DO know from a roadtest that the Car is tailhappy as ****.

Looks exactly like a regular E53
