The four-door BMW M8 Gran coupe is coming to America next year, completing the M lineup in the US. Like the M8, the excellent 4.4-liter twin-turbo will be featured under the hood, making 592 horsepower and 553 lb-ft of torque. Coupled to an all-wheel-drive system with a rear bias and subject to driver override, the M8 can hit 0-60 in 3.3 seconds and a top speed of 190 MPH with the optional M Driver's Package. The M8 Competition will net you 616 horsepower and cut a tenth of a second of the 0-60 time, but the top speed remains unchanged. The front and rear suspension utilize new components to keep the extra power on the ground, along with an active differential, electronically-assisted steering, and adaptive suspension. The interior has M-specific seats, along with optional carbon-fiber trim and a 10.25-inch infotainment screen. The M8 Gran will come to dealerships early next year.
