The BMW M6 is a more powerful version of the elegant 650. Available as either a coupe or a convertible, it is designed to appeal to the sport luxury enthusiast, providing heightened performance and subtly aggressive styling.

The M6 boasts the same muscular 500 hp 5.0-liter V10 engine as the M5, along with enhanced suspension and brakes. A 7-speed Sequential Manual Gearbox (SMG) with steering wheel paddles is standard; a conventional 6-speed manual transmission is also available. Both the coupe and convertible are built using lightweight aluminum, carbon fiber and composite materials, allowing the M6 an excellent power-to-weight ratio. Distinguishing standard features include exclusive M designed 19-inch forged alloy wheels, heated leather M sport front seats and BMW’s M Drive button on the steering wheel to save and retrieve preferred driving settings.

For 2008, the BMW M6 receives a minor exterior refresh, with a revised headlight design, LED turn signals and a more pronounced rear trunk lip. New options for 2008 include a heated steering wheel and High-Beam Assistant autodimming headlamps.

The 2008 BMW M6 is a car that can only really be appreciated on the track. Its cabin electronics make it suitable for everyday driving, but its fuel economy keeps it from being practical.

The World’s First crossover Coupe called by BMW a Sports Activity Coupe.

2008-2009 BMW X6 – four door coupe - looks awesome with corners – combination of sports car and SUV – Dynamic Performance Control – two twin-turbocharged models, with inline-6 or V8 power …

The X6 comes in two trim levels. The $53,275 “X6 xDrive35i” comes with that coolest 300-hp, 300-lb-ft twin-turbo in-line six that we adore in the 135i, the 335i, and the 535i. Saddled with the X6′s weight (4894 lb), the overachiever of an engine still manages a 6.5-second 0-to-60-mph time. lovely!

The ”X6 xDrive50i” starts at $63,775 and has an all-new V-8 under the hood. At 4.4 liters, the engine is smaller than the 4.8-liter in the other 50i-engined cars (the 550i, 650i, and 750i, to name a few) and the X5 4.8i. In place of the displacement, it packs two small turbos in the valley of the engine block’s vee, and consequently it makes even more power: 400 hp and 450 lb-ft of torque. (The normally aspirated 4.8-liter makes 350 hp and 350 lb-ft in the X5). The engine’s power – and its huge torque plateau – are nice, but it experiences a lot more lag than the six-cylinder does, even at high rpm.

The conclusion I got about this technology is that the X6 is a complete rocket around a racetrack. Both 35i and 50i models understeer slightly, but they generate truly astonishing grip, brake very well, and accelerate very quickly. It’s doubtful that any SUV on the planet could keep up.
