BMW adds four-cylinder twin-scroll turbo power to X3

As a relatively compact crossover, you might expect the BMW X3 to be available – in this climate even in the United States – with a four-cylinder engine. But that wasn't the case until now, as BMW has announced the availability of its TwinPower Turbo four to replace the 3.0-liter six-cylinder mill in the X3 xDrive28i. The N20 engine is the same unit that's already available in the Z4, 528i and new 328i, and joins the X3 along with a raft of upgrades for the 2013 model year.
