“What we’d like is more focus on lightweight engineering,” says Collins. “The philosophy will be around delivering performance through improved use of materials – lightweight alloys, lots of carbon fiber etc – rather than simply trying to make the engine more powerful to move the same kind of car, or scaling it back too far so that it loses its M3 roots.” BMW M CEO, Dr. Friedrich Nitschke himself confirms that they are indeed working on weight reduction efforts for the new M3/M4.
Collins also mentions that the experience learned from the i3 and i8 projects involving carbon fiber parts is something that they could use in future BMW vehicles.
When asked about a future M3 CSL, Collins says: “There are no plans at the moment to build a lightweight CSL version of the M4, but there weren’t any plans to do the last-generation CSL either. We have to see what the customers think, and if there’s potential for an even more lightweight version, we’ll do it.”
The new BMW M4 will go on sale next year, powered by a six-cylinder turbocharged engine delivering 440 horsepower.
