Starting at $73,000, you get a similar, but de-tuned version of the twin-turbo 4.4L V8 used in the M-Cars. You also get AWD and an eight-speed automatic gearbox. It's even capable of doing 0-60 in under four seconds and 165 mph (limited) right out of the box, quicker than the old M5. But what happens when BMW tuner DINAN gets their hands on it? 600 Horsepower and 627 lb/ft of torque, with a factory warranty. learn more at: http://www.dinancars.com DINAN provided the test vehicle, insurance, and a tank of fuel for this review.
