The 2010 X6 M represents the most dramatic shift in BMW’s Motorsport division since its inception – and it’s not because they’re the first crossovers branded with the tri-tone “M” badge. This high-riding duo are the first M machines ever to be equipped with all-wheel drive. The first fitted exclusively with an automatic transmission.

The X6 M is a high-performance variant of BMW’s controversial head-turning crossover. Unveiled at the New York Auto Show in 2009, the X6 M uses a potent version of BMW’s twin-turbocharged 4.4-liter V8. Output is pegged at 555 horsepower at 5,750 rpm and peak torque is 501 pound-feet, available between 1,500 and 5,650 rpm. The car can accelerate from zero to 60 mph in 4.7 seconds, according to the automaker.

Pros:

* Ferocious power
* Dynamic BMW handling
* Merino leather seats cradle the passengers in luxurious comfort
* Appeals to a niche market

Cons:

* Barely acceptable rear cargo space
* Limited view looking back through hatchback window
* Head-up display is marginally useful
