The hulking and incredibly fast red aberration you see here provides a rolling look into BMW madness. The engine, for example. BMW has a twin-turbo 4.4-liter V-8, but these engineers figured 400 horsepower simply wouldn’t do. So on went new pistons, camshafts, turbochargers, and a modified cooling system, amongst other things. The engineers finally settled on 555 horsepower, a number so convenient they might as well have called it “enough.” They then programmed in a launch control system, because what good is a 5181-pound SUV if it can’t accelerate?
This BMW reaches 60 mph in 4.0 seconds and the quarter mile in 12.5 seconds at 110.8 mph. How? With the transmission in manual mode, all that’s required from the BMW driver is that they press the inconspicuous “M” button on the steering wheel and flatfoot both pedals. And when the checkered flag appears on the dash, they sidestep the brake. As the all-wheel drive jettisons the X6 M from its place of rest, the transmission takes care of the upshifts — the driver is merely along for the ride.
The trouble now is you’re going rather fast, and the X6 M still weighs 5181 pounds. Fortunately, BMW engineers realized that with that kind of power to weight, the X6 M will need to stop at some point, preferably before anyone gets hurt. On went rotors measuring 15.6 inches up front and 15.2 inches out back. Tires, they also decided, might as well match the preposterous brakes.
Utterly capable and continually surprising, the X6 M earns the interest of very serious enthusiasts.
