, multi point fuel injection, and precise variable valve timing (VVT) to insure that every ounce of performance is delivered at the driver's whim. Feeding off an 18.5 gallon capacity of high grade unleaded gasoline, the fuel economy of the BMW M6 probably isn't why you want this car: it's a 11 miles per gallon in the city and 17 mpg on the highway. The reason you want this car is because of its style, comfort and speed; mostly the speed. The 5.0 liter drives the rear wheels to remarkable performances such as a 12.8 second quarter mile. When considering the M6's power to weight ratio of 1 horsepower per 8 pounds, it's easy to understand why driving this car can feel like driving a racing car.
