Edmunds.com tests hundreds of vehicles a year, but not every vehicle gets a full write-up. The numbers still tell a story, though, so we present "Track Tested." It's a quick rundown of all the data we collected at the track, along with comments direct from the test-drivers. Enjoy.
When BMW introduced the idea of the SAV (Sport Activity Vehicle) with the original X5, we scoffed appropriately. Then we drove it and were shocked that the ungainly beast was not ungainly at all. Then BMW took it a bit further and rolled out the X6. It appeared even more useless, yet it, too, was a surprisingly entertaining drive.
BMW didn't stop there, of course, as it rolled out Motorsport versions of both the X5 and the X6 earlier this year. There was no good reason for them to exist, but BMW went ahead and built them anyway. After testing the X6 M, we're glad BMW took the time.
You see, this X6 is so fast that its odd looks, big sticker and pointless existence don't really matter. You simply have to respect it for what it can do. And we're not just talking about going fast in a straight line. It stops and turns amazingly well, too. It's a triumph of engineering over design and marketing. Just take a look at the numbers if you don't believe us.

Handling Rating: Very Good
Db @ Idle: 43.3
Db @ Full Throttle: 70.4
Db @ 70 mph Cruise: 66.0
Acceleration Comments: Very quick in default mode. Few will ever need to use "M" mode. Still, this thing absolutely honks with all the limiters turned off. Best run with minimal brake torque -- all while ignoring launch control "flag" indicator.
Braking Comments: First run was the shortest (107 feet!). Consistent pedal, but distances got longer with every stop (up to 112 feet).
Handling Comments: Skid pad: Truly an impressive-handling SUV. Corners dead flat, offers incredible feedback and has enough power to influence chassis. But why can't I disable stability control? Slalom: Stability control never is truly off, which is why "on" number is faster than "off" number -- get aggressive with it off and it will punish you.
