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.

The range topping BMW X6  Drive50i is propelled by an all-new twin-turbo 4.4-liter V8 unit producing 400 horsepower at 5500 rpm and 446 pound-feet of torque between 1750 rpm and 4500 rpm. The sprint to 62 mph takes just 5.4 seconds and fuel economy is estimated at around 19 mpg (U.S. gallons). The engine is designed as a replacement to the company's current 4.8-liter naturally-aspirated V8. It is expected to filter into other models like the 5-Series, 6-Series and 7-Series in the near future. The engine seems to represent the second stage in a shift at BMW from high displacement naturally aspirated motors to slightly smaller turbocharged powerplants. BMW's twin turbo 3.0-liter engine that powers the 335i and 135i has been met with overwhelmingly positive reviews, and it appears BMW is hoping for similar results with its new V8.

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.
