X3 slots below BMW's larger, costlier X5, but has near-identical passenger space, more cargo volume, and is some 600 lb lighter. Like X5, the X3 seats five, has a liftgate with fixed glass, and includes BMW's xDrive all-wheel drive. A 225-hp inline 6-cyl is the only engine. A 6-speed manual transmission is standard; a 5-speed automatic with manual shift gate is a no-cost option. Despite 8 inches of ground clearance, X3 is intended only for light-duty off-roading. Its AWD lacks low-range gearing, but includes hill descent control. ABS and traction/antiskid control are standard. So are front side airbags and head-protecting tubular side airbags; rear torso side airbags are optional. Also available is a Sport Package that includes firmer suspension and sport front seats. A sunroof and rear glass skylight are standard. Options include leather upholstery, navigation system, steering-linked xenon headlamps, and front and rear obstacle detection.
