The best part about this 2010 BMW X6 active hybrid? The shut-off feature. When the driver gets out of the car and shuts the door, the car shuts off. That’s right, completely off. The reason, says Tomas Greger, a member of the BMW X6 active hybrid team, is safety. People have gotten out of their hybrids without shutting them off. They do this because the hybrid electric motor is so quiet they forget. But when the battery runs down the combustion engine kicks on and your garage could fill up with carbon monoxide and kill you.
BMW has combined the 4.4-liter, twin-turbo V-8 engine that produces 400 horsepower with two electric motors and a cobasys nickel-metal hydride battery. The result is a high-performing 478 horsepower with 575 lb.-ft of torque.
Numbers, you need numbers: The U.K. has already certified the fuel numbers for the gasoline version and the active hybrid.
The gasoline version of the BMW X6 gets 12.8 liters per 100 kilometers. In imperial miles that would work out to 18.4 miles per gallon. In the United States that equals 15.3 miles per gallon.
The 2010 BMW X6 active hybrid gets 9.9 liters per 100 kilometers. In imperial miles that would work out to 23.75 miles per gallon. In the United States that equals 19.7 miles per gallon.
The fuel mileage is about twenty-two percent better than the gasoline version. The price is about twenty-four percent higher, with the gasoline version starting around $67,000 and the active hybrid starting at $87,000ish.
