After more than two decades away, the BMW 8 Series is finally back. The first to arrive in the US is the M850i xDrive model, which is available as a coupe or convertible. Under the hood is a 4.4-liter twin-turbo V8 producing 523 horsepower and 553 lb-ft of torque going out to all four wheels through an eight-speed automatic. 0-60 mph takes just 3.6 seconds, though there is an even quicker M8 on the way. Pricing starts at $111,900 for the coupe and from behind the wheel, it feels worth every penny.
