On the edge of your seat waiting for the next-generation M5? BMW is still keeping their new super sedan under wraps, but if you're becoming impatient, the Bavarians have served up a new top-of-the-line model with the new M550i. Under the hood is a turbocharged 4.4L V8 that produces 456 hp and 480 lb-ft of torque, which will get you from 0-60 in an ultra quick 3.9 seconds while your top speed is limited to 155 mph.
That power is sent to all four wheels as the car is equipped with BMW's xDrive system, a perfect accompaniment to the powerful V8. Other performance features include an M Sport suspension that lowers the car by 10mm, 19" M light alloy wheels, M Sport brakes, and an M Aerodynamic package that includes an M rear spoiler with Gurney flap.
