When BMW->ke178 brought the X6->ke2396 to the market, we had some doubt about its ability to succeed, but luckily the model proved us wrong. So when the M version was also dropped, we had no doubts that it will instantly become of the best sold sports SUV on the market. After all, with 555 horsepower under the hood, who can ask for more, right?

Well, the answer is German tuner, Inside Performance, which has unveiled a sweet Stealth package based on the X6 M. The tuner decided the car can pump out much more power than the standard model, so it installed a special exhaust system available in two power levels. Level 1 it gets 3-inch piping and up to 3-inch valves, and level 2 gets new downpipes and new generation 200-cell sports metal catalysts. The result is an output of 700 horsepower and 626 pound-feet of torque.

In order to handle the extra power, the tuner installed new 22-inch alloy wheels and adjustable suspension. The exterior has been wrapped in an army-style foil.

About the standard BMW X6 M

BMW unveiled the X6 M in 2009, just one year after the standard X6 arrived on the market. When compared to a standard X6, the M version received numerous M design elements and an adaptive suspension system. The X6M was revised for the 2013 model year with revised headlamps, a very cool "Power Dome" hood and new taillights.

The X6 M is powered by a 4.4-liter twin-turbo V-8 engine producing 555 horsepower and 501 pound-feet of torque. This amount of power is enough to sprint the SUV from 0 to 60 mph in just 4.5 seconds and up to a top speed of 155 mph.
