After a long wait, BMW has finally unveiled its long-rumored four-cylinder turbocharged gasoline engine on the X1 xDrive28. This four-cylinder engine essentially replaces the automaker's classic naturally aspirated 3.0-liter straight-six, and what's more is that we can expect to see it spread to over to a variety of models. Among the models expected to receive the new engine are the 1-Series, X3 3-Series, Z4 Roadster, and 5-Series.

This engine is the first to employ BMW's TwinPower Turbo technology. With a displacement of 2.0-liter, it can produce an output of 245-horsepower at 5,000 rpm and a peak torque of 258 lb-ft. The 3.0-liter six-cylinder engine in the outgoing X1 xDrive28 was rated at 258-horsepower, so the difference isn't much. A six-speed manual transmission is standard, but there's the option of an eight-speed automatic transmission. The new X1 xDrive28 will have its world premiere at the upcoming Geneva Motor Show in March and will go on sale across Europe this spring. There's still no information regarding U.S. availability.
