For those who are comfortable driving at the limit, Dynamic Stability Control includes Dynamic Traction Control. A button lets the driver choose a higher threshold of wheel-slip before DSC engages, and though this technique is good for starting off on loose snow, it can also be used to turn the X3 into even more of a driving machine.
The six-speed automatic proved to be smooth and precise in normal, everyday driving. Just put it in Drive and go. When pushing it in the slippery stuff, the automatic frees the driver to focus on braking, accelerating and steering, which can be a lot of fun. When so inclined, the driver can use the Steptronic feature to hold the transmission in a specific gear, manually shifting up or down as the incline or traction dictates or invites.
The six-speed manual transmission, on the other hand, is everything people who know and like BMWs have come to expect and appreciate. Shifts are smooth and precise, clutch engagement predictable and gears properly spaced to keep the engine in the sweet spot of its power band, although it is geared a bit high for relaxed long distance cruising. We prefer the automatic.
Acceleration is silky, linear and quick , thanks to the 3.0-liter inline six-cylinder engine's 260 horsepower. The 3.0si records 0-60 mph times of 6.9 seconds for the manual and 7.1 seconds for the automatic. While not blistering performance figures, considering the vehicle's weight, are no cause for shame.
The optional Servotronic steering is flat-out wonderful. It's speed-sensitive, adding more assist at low speeds, and invisibly altering the steering ratio, so the car turns more with less steering input. Parallel-parking is a breeze, as are quick, mid-block U-turns. As speed increases, assistance diminishes and the ratio slows, making for good on-center feel and sure lane changes. Perhaps the best thing about the Servotronic steering is its transparency; unless a driver moves directly from the X3 to another vehicle without the feature and suddenly has to crank in more steering at slow speeds, it'll likely not be noticed at all.
Braking is smooth and sure, with solid pedal feel allowing linear, gradual stops when desired, unlike many over-assisted systems increasingly popular on high-end cars and SUVs. BMW usually accompanies engine upgrades with improvements to such dynamic elements as braking and handling, and it's just so with the X3 3.0si.
