BMW is currently mulling a range of four-cylinder engines for the U.S. market, but the German automaker could be downsizing its powerplant offerings even further in the coming years. BMW is reportedly mulling a new three-cylinder powerplant for its entry-level models.
Sources familiar with the situation revealed to Auto Motor und Sport that BMW is currently testing a new three-cylinder engine for its next-generation 1-Series, due out in 2011. The new three-pot displaces 1.35L and can generate between 120 and 180 horsepower, depending on tuning.
Although the new three-cylinder is being designed with the 1-Series in mind, it could eventually find its way under the hood of the larger 3-Series. However, BMW has yet to confirm a three-cylinder engine is even under development.
The reports seem to coincide with BMW’s plan for a greener future. BMW will replace many of its six-cylinder engines over the next few years with four-cylinder units, with direct-injection and turbo charging more than making up for any losses in displacement. And with the next-gen 1-Series expected to shed some weight, a high-output three-cylinder could be just the ticket for excellent fuel economy and BMW performance.
