If you’re in the market for a 2013 BMW 5 Series or 6 Series with a V-8 under the hood, we’ve got some good news for you: the more powerful twin-turbo V-8 used in the latest 7-Series and the 6-Series Grand Coupe will soon find its way into 5 and 6-Series models.
Word from Car and Driver is that 2013 BMW 550i, 550i GT and 650i coupe and convertible models will all get the new engine, rated at 445 horsepower and 480 pound feet of torque. That’s a gain of 45 horsepower and 30 pound feet of torque compared to last year’s models, courtesy of BMW’s Valvetronic variable valve timing system.
Valvetronic boosts fuel economy as well as horsepower, and BMW claims that its new 4.4-liter twin-turbo V-8 is some 25-percent more efficient that the engine it replaces, at least in the 750i sedan.
