BMW's M badge previously was only affixed to sedans and coupes, but now it has been extended to the X5, marking not only first time it goes on an SUV, but also the first time it gets applied to an all-wheel-drive vehicle.
Externally, the X5 M distinguishes itself from the standard X5 mainly through the front body work. On the M version, big vents filled with black honeycomb grilles stand ready to suck in air to feed the twin turbos.
The new iDrive controller includes quick access buttons to call up major cabin tech functions, such as stereo, navigation, and phone. The Option button is a little confusing, as there is a separate settings menu available on the car's LCD.
