The History of BMW Motorsport and the E90 320d WTCC

BMW has been a leading player in motorsport for decades, with a rich history dating back to the early years of racing. The German brand has made a name for itself with its innovative engineering and groundbreaking performances across various racing categories, including Formula 1, Le Mans, and, of course, the World Touring Car Championship (WTCC).

In 2006, BMW Motorsport introduced a bold and revolutionary race car: the BMW E90 320d WTCC. Based on the then-current 3 Series (E90), this model was one of the first diesel-powered race cars in the WTCC. While other manufacturers stuck with traditional petrol engines, BMW saw an opportunity to harness the efficiency and torque of a diesel engine.

The BMW 320d WTCC was a true technological masterpiece, developed to push the boundaries of diesel technology in motorsport. The car gained worldwide recognition through its success in the WTCC, proving that diesel could not only be efficient and powerful but also capable of winning races at the highest level.

The BMW 320d WTCC in action – victories and racing history

The introduction of the BMW 320d WTCC was a game-changer in the World Touring Car Championship. While most teams ran petrol-powered cars, BMW set a new trend by using a turbo diesel engine. This not only resulted in better fuel efficiency during long races but also provided a significant torque advantage when accelerating out of corners.

One of the most memorable performances came during the 2008 WTCC season, when the BMW 320d WTCC, driven by Andy Priaulx, competed against renowned manufacturers such as SEAT, Chevrolet, and Alfa Romeo. Despite fierce competition, BMW secured multiple race wins, proving that diesel engines could be competitive in motorsport.

Notable achievements:

• 2006-2010: Consistent podium finishes in the WTCC championship
• 2008: Victories against petrol-powered cars, proving BMW’s diesel technology was a force to be reckoned with
• Dominance on technical circuits, where torque and fuel efficiency played a decisive role

What made the 320d WTCC extra special?

• The first successful diesel race car in WTCC
• A unique combination of torque, efficiency, and performance
• A bold move by BMW Motorsport that changed the face of racing
• Unforgettable races and iconic performances in the late 2000s

With this car, BMW demonstrated that innovation and boldness go hand in hand with success. The BMW E90 320d WTCC remains a legendary touring car that left its mark on motorsport history.
