BMW X6
The BMW X6 is a mid-size luxury crossover released for sale in the second quarter of 2008 for the 2009 model year by German automaker BMW. The X6 was marketed as a Sports Activity Coupe (SAC) by BMW. It combines the attributes of an SUV (high ground clearance, all wheel drive and all-weather ability, large wheels and tires) with the stance of a coupe (bold styling, dramatic sloping roof). The concept model debuted at the 2007 Frankfurt Auto Show and the production X6 officially debuted at the 2008 North American International Auto Show in Detroit and Montreal International Auto Show. While slightly longer and wider than the X5, it is significantly lower and seated initially only four, and since 2011, optionally five.[2] It is built in BMW's North American plant in Greer, South Carolina alongside the BMW X5, whose platform it shares. It is dubbed a "Sports Activity Coupe (SAC)" by BMW. A hybrid version, the BMW Concept X6 ActiveHybrid, which will be the first such vehicle from BMW, was also announced.[2][3] Later, in April 2009, the sporty X6 M version was announced, with a 555 hp (414 kW) 4.4-liter turbocharged V8.[4] The first BMW X6 models were released for the North American market in two variants, both powered by twin-turbocharged gasoline engines. The base model is the X6 xDrive35i which is powered by the 225 kW version of the N54 3.0-litre twin-turbocharged inline-six gasoline engine. The top-of-the-line model is the xDrive50i which uses the N63 V8 engine, producing 300 kW.

nstitute as much as 90% of sales volume in European markets. The models are called the xDrive30d and xDrive 35d, respectively. They are powered by BMW's 3.0-litre turbodiesel engine (in its sequential twin-turbocharged variant for the xDrive35d), and produce 235 PS (173 kW) in the xDrive30d and 286 PS (210 kW) in the xDrive 35d version. The second of these power units will form the basis of BMW's Diesel launch in all 50 states in late-2008. The BMW X6 M and X5 M are the first vehicles from BMW M GmbH to have xDrive all-wheel-drive system and automatic transmissions, and are also crossovers as opposed to passenger cars. The X6 M was unveiled at the 2009 New York Auto Show[9] and first went on sale in the 2010 model year. The high-performance M derivative features a twin scroll twin turbo version of the 4.4-liter V8 BMW N63 engine with the Cylinder-bank Comprehensive Manifold (CCM).[10][11] The engine is rated 555 PS (408 kW; 547 hp) at 6000 rpm and 680 N·m (500 lb·ft) at 1500-5650 rpm.[citation needed] Other features include 6-speed M Sports automatic transmission with aluminum pull-style paddles on steering wheel, M Dynamic Mode feature, 10 mm (0.4 in) lower Adaptive Drive suspension, 4-piston fixed calipers with 15.6" rotor at front and single piston floating calipers with 15.2" rotor at rear, 20-inch alloy wheels with 275/40R20 front and 315/35R20 run flat tires, hill descent control, dynamic stability control, special gills in the front fenders, 20-inch light-alloy wheels.[12] The car can accelerate from zero to 60 mph (0–97 km/h) in 4.5 seconds and 0-62 mph (0–100 km/h) in 5 seconds.[13]
