This is one of the best upscale SUVs, melding 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 though 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 rear-drive versions are available.
