Spare partsThe 6-Series is BMW's flagship 2-door grand tourer, offered in both coupe and convertible body styles. For 2012, it's been redesigned on the outside, giving it a much leaner look than the previous model with a lower trunkline, revised grille and headlamps, and new tail lamps. And although it looks smaller due to the redesign, it's actually three inches longer and an inch and a half wider than the car it replaces, helping to increase interior room.

Three models are available in the U. S. for 2012: the 640i, 650i and, back after a year off, the M6. At the heart of the 6-series' redesign is a lineup of all-new engines, which replace last year's 360-hp 4.8L V8.

The 640i comes with a 3.0L turbocharged 6-cylinder engine that also uses direct injection to produce 315 horsepower. The 650i comes with an all-new 4.4L turbocharged V8 engine that makes 400 horsepower. The M6 carries with it an impressive 4.4L V8 with a twin-scroll turbocharger that makes 560 horses.

The 3.0L is paired with an 8-speed automatic transmission. The 650i comes with the 8-speed transmission, but a 6-speed manual transmission can be installed at no charge.
