BMW E30 M3
When most people think of BMW performance, they think of the “M” class cars. Among dozens of models that wore the M badge, the M3 E30 is the most iconic. The heart of the E30 M3 was the S14 straight-four engine with 2.3-liters of displacement and 195 and later 215 HP.
Since the car was light, its performance and road-holding was great. In fact, the M3 turned out to be the most successful racing car in touring car racing history.
