Could the next-generation BMW M3 and M4 models return to their four-cylinder roots?
With potent turbocharged four-cylinder engines becoming more common, such as in the Mercedes-Benz CLA 45 AMG, BMW isn’t ruling out the possibility that its next-generation M3 and M4 sports cars may benefit from the technology. Despite not currently having a four-cylinder engine in its entire lineup, BMW M Division Head of Product Management Carsten Pries recently said that it was “foreseeable” that a four-cylinder engine could be found lurking under the hood of the next-gen M3 and M4.
The latest 2015 BMW M3 and M4 are both powered by a 3.0-liter twin-turbo inline-six engine, which is about 25 percent more fuel efficient than the previous V8 engine found in the last M3. Thanks to a pair of turbos, the new engine also offers significantly more performance.
Naturally, the biggest concern BMW faces heading into the future is meeting increasing emissions regulations worldwide, which means a four-cylinder with plenty of power would be a good compromise.
