The most relevant announcement to BMW customers, however, will be the return of 4-cylinder engines to the BMW lineup in North America, as well as the debut of the first model to use the new TwinPower Turbo 4-cylinder mill.
In Europe the first car to get such an engine was the X1 xDrive 28i, with a turbocharged 2.0-liter making 245-hp at 5000 rpm and 258 lb-ft of torque at just 1250 rpm. That same engine is expected to replace the current 3.0-liter straight-six in much of the BMW lineup, delivering 13 fewer horsepower, but 30 more ft-lbs of torque. In the X1 model BMW claims an improvement of 0.7 seconds to 62 mph with the manual and 0.3 seconds with the automatic, resulting in a very impressive 6.1 second (or 6.5 second) 0-62 mph time. Also of note is a 4.8 mpg improvement on the Euro test cycle.
