All 2012 BMW X5 models are all-wheel drive but shoppers may choose from three available engines. The xDrive35i is powered by a 3.0-liter turbocharged inline-6 that produces 300 hp and 300 pound-feet of torque. The 2012 BMW X5 is one of the best-handling midsize luxury crossovers around. Whether driving on back roads or on an endless expanse of interstate, the X5 is a champ. Some competitors offer more utility and off-road capabilities, but the X5 ably brings BMW's legendary handling prowess to the SUV arena. You'll notice the elevated ride height and considerable curb weight on tight roads, though. Engine performance is strong throughout the lineup, even with the base six-cylinder.
