In an interview with Auto Motor und Sport, Norbert Reithofer spoke about BMW killing the V8 diesel and replacing it with a more efficient twin-turbo inline 6-cylinder engine. BMW’s CEO also said that the automaker is considering using fewer cylinders in its high-performance M lineup.
BMW first launched a 4-cylinder engine in its M cars with the first generation M3. Following that, BMW’s M division started using 6-cylinders and today, the M5 sedan and M6 coupe use V10 engines producing up to 500-hp. In order to improve fuel-efficiency the German automaker is now considering going back to using less-cylinders while cutting down weight.
Reithofer said he would like to see more BMW models downsizing their engines to improve fuel-economy while using twin-turbo technology to increase performance.
