This is one of the best upscale SUVs, melding SUV utility with luxury car attributes and driving fun. It has precise handling and a composed ride, although the body tends to rock side-to-side on uneven pavement. The 2.0-liter, turbo four-cylinder returned a very good 23 mpg overall and the eight-speed automatic shifts seamlessly. But this engine is a bit short on refinement, with a diesel-like clatter. The six-cylinder in the 35i is silky smooth. The interior is beautifully finished, with firm and supportive front seats, and while the rear seat is roomy, cargo capacity is modest. Once mastered, the iDrive control system proves logical. Despite the X3's price, the must-have rearview camera is optional. A diesel and a rear-drive version are available.
