Luxury Car - BMW X6, mid-size luxury crossover by German automaker BMW

The BMW X6 is a mid-size luxury crossover released for sale in the second quarter of 2008 by German automaker BMW. The X6 was marketed as a Sports Activity Coupé (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 coupé (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.

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 Coupé (SAC)" by BMW. A hybrid version, the BMW Concept X6 ActiveHybrid, which will be the first such vehicle from BMW, was also announced. Later, in April 2009, the sporty X6 M version was announced, with a 555 hp (414 kW) 4.4-liter turbocharged V8.

Initially, the BMW X6 was available in North America (Now released in the UK) in two variants. Both use twin-turbocharged engines. The top-of-the-line model is the xDrive50i which uses an all-new 4.4-litre twin-turbocharged V8 engine. This all new version of the 550i/650i's engine (N62) is being used with twin turbo technology from the 135i/335i. It produces 408 PS (300 kW; 402 hp) between 5,500 and 6,400 rpm, and 600 N·m (440 lb·ft) of torque over a wide range of between 1,800 and 4,500 rpm. It is the first production turbocharged V8 engine in the world to feature its turbochargers between the 'V' section in the middle of the two banks of cylinders. The exhaust and intake manifolds are in the un-traditional position - exhausts top of the engine and engine intakes directed to the outer sides of the 'V'.

The other model is the X6 xDrive35i powered by the N54 3.0-litre twin-turbocharged inline-six gasoline engine, producing 306 PS (225 kW; 302 hp) between 5800 and 6250 rpm, and a peak torque of 400 N·m (300 lb·ft) between 1400 and 5000 rpm. This engine also sees duty in the 1, 3 and 5 Series BMW cars.
