The X5M is bar none the fastest SUV on the planet. Like every M vehicle BMW builds, this one can be driven comfortable in traffic and can perform with the spirit of a true sports car. The balance and handling were a big surprise, the engine wasn't. Its feels like 555hp, more so in launch control.
The real surprise was the cold weather characteristics of this vehicle. It was the best 'winter beater' I've had the pleasure to drift around the snowy corners of a Wal-Mart parking lot. It certainly gives you a confident feel.

I highly recommend comparing this vehicle to any, because it can't be beat.
