The 5-passenger X4 is all-new for 2015. It is based on BMW's X3 SUV platform, but is longer, lower and sportier. There are two engines, a 4-cylinder in the xDrive28i and a 6-cylinder in the xDrive35i, and all X4s come with an 8-speed automatic and all-wheel drive.
About BMW X4
In its ongoing quest to make a vehicle for every buyer no matter how small the niche, BMW has created the all-new 2015 X4, which is sportier than a typical 5-passenger SUV (and not quite as practical). This is a vehicle that is difficult to categorize, but because its underpinnings are based on those of the X3 SUV, it makes sense to think of this as an SUV variant. Its unique coupe-like style sets it apart from the rest of the SUV crowd, and puts it in a group with standout lookers like the Land Rover Range Rover Evoque and, to a lesser extent, the Mercedes-Benz GLK.
