3. Aerodynamic Enhancements
Numerous aerodynamic enhancements were made in all areas of the bodies for the M3 and M4. The goal of the engineers was “to channel the air around the car to create the best possible platform for dynamic excellence.” Not only that, but cooling was enhanced for the engine, powertrain and brakes, even when operating under heavy loads on the track. Reducing lift by an equal degree at the front and rear axle is the defined Gurney spoiler on the rear of the M3 sedan and the integrated spoiler lip on the M4 coupe. “The way in which we channel the inflowing air through the engine oil cooler creates a Venturi effect, which reduces front axle lift and, in so doing, improves the steering,” explained BMW development boss Albert Biermann.
