For this new 5th series, the Bavarian manufacturer asked that its subsidiary, Motorsport, improve it further. The fabulous 6-cylinder line engine was pushed to 315 horsepower, giving this bourgeois car a distinct sports car feel. The road handling of the car was completely reviewed, with the car being lowered, equipped with larger anti-roll bars, as well as firmer springs. This BMW became as powerful as a Ferrari, as reliable as a Porsche, and was a unique car in the industry. It paved the way for a new generation of sedan sports cars.
