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.

The move also gets BMW one step closer to a common twin-turbo V-8 throughout its product line, and standardization is one way for a manufacturer to realize maximum cost savings. That’s not to say that all V-8 BMW’s will use the new engine, since there are still two holdouts getting last year’s engine.

For now, at least, the X5 and X6 crossovers will soldier on with the lower output 4.4-liter V-8, which still makes a respectable 400 horsepower and 450 pound-feet of torque.
