Having facelifted the 3 Series and introduced the next-generation 7 Series, BMW is now hard at work putting the finishing touches on its other core sedan – the 5 Series. Set to debut early next year, the eighth generation could be the first since the E28 of the 1980s to come without a V8, at least in the non-M guise. Our friends at BMWBLOG claim the M550i xDrive will be discontinued, therefore taking away with it the twin-turbo 4.4-liter engine.
