In 1990, with an already successful agenda on the track, BMW introduces the Sport Evolution. The Sport is the third and final special edition Evolution M3 and by far, the most radical of the street-going M3's. Production reaches 600 to surpass the 500 models required for homologation in Group A DTM.M Bolaños escribió:Le dejo de tarea revisar cuanto costaba el M3 E30 (creo que se llamaba, el que se dejó de hacer en 1998). ---> S14
Además un carro que lo catalogan como "Best Handling Car In the World" (Car And Driver) no creo que sea tan "basura" como usted lo está decribiendo.
While there are many specific alterations to the Sport Evo which vary from the standard M3, several modifications focus on achieving maximum competitive advantage in Touring Car racing. Rules of the time require that racing models (a) run the same engine and displacement as the homologated car and (b) no sheet metal or aerodynamic aids can vary from the homologated model.
For this reason, the Sport Evolution displaces 2467cc, nearing the 2500cc Group A limit. The Sport Evo is equipped with a multi-position adjustable front splitter and rear lip spoiler so that downforce can be dialed in on a per track basis. Wider fender wells allow clearance of larger 18" racing wheels.
