Takes all surfaces in its stride.

The BMW xDrive all-wheel drive system on the
BMW 3 Series Sedan.

In the BMW 325xi, 330xi and 330xd, the xDrive all-wheel drive system provides more traction, directional stability and safety. On dry roads, xDrive distributes 40% of the power to the front wheels and 60% to the rear, combining the advantages of four-wheel drive with the agility of a BMW 3 Series. If the system senses the possibility of the car spinning when driving on wintry roads, it redistributes power between the axles within milliseconds, preventing under- or oversteer before it starts.
