To the power of eight. The eight-speed automatic transmission Steptronic in the BMW X6.

The rev counter is the only place you'll notice: with the new eight-speed automatic transmission the smaller increments from one gear to the next don't just increase ride and shift comfort in the BMW X6, they also enable faster gearshifts and more profitable use of the optimum rev range. This reduces fuel consumption and lowers CO2 emissions. The system is supported by the newly developed converter clutch – even if you use the electronic gearshift lever to shift manually.

Higher torque, lower consumption. The six-cylinder diesel engines in the BMW X6 xDrive 30d and xDrive 40d.

Both diesel engines in the BMW X6 xDrive30d and the xDrive40d use state-of-the-art common rail diesel technology for higher performance and singularly low consumption. The turbo diesel engine in the BMW X6 xDrive30d delivers 180 kW (245 hp) and 540 Nm of torque, yet consumes just 7.4 l/100 km (EU composite figure). Even more efficient is the BMW X6 xDrive40d with its BMW TwinPower Turbo technology: here, two turbochargers work in sequence to deliver impressive power curves and high rpm. With 225 kW (306 hp) and 600 Nm of torque under the bonnet, the car sprints from 0 to 100 km/h in just 6.5 seconds – yet consumes a mere 7.5 l/100 km (EU composite figure).

The BMW TwinPower Turbo straight six-cylinder petrol engine in the BMW X6 xDrive35i.

The 3-litre drive train with BMW TwinPower Turbo technology combines a TwinScroll turbocharger with Valvetronic, double-Vanos and High Precision Injection. The result is a high degree of revving power complemented by high torque and low consumption. With 400 Nm available from just 1,200 rpm upwards and a power output of 225 kW (306 hp), this engine is one of the most powerful in its class. And with a fuel consumption of just 10.1 l/100 km (EU composite figure), it's also extremely efficient.

A new chapter in the history of engines.

The BMW TwinPower Turbo eight-cylinder petrol engine
in the BMW X6 xDrive50i.

In the BMW X6 xDrive50i, TwinPower Turbo technologies join forces in a V8 engine for the first time ever. High Precision Injection, two turbochargers anddouble-Vanos all combine to deliver higher performance and lower fuel consumption. The figures speak for themselves: with 300 kW (407 hp), up to 600 Nm of torque between 1,750 and 4,500 rpm and an average fuel consumption of 12.5 l/100 km (EU composite figures), the 4.4-litre V8 engine in the BMW X6 xDrive50i delivers best-in-class efficiency. Another world premiere is the engine's exhaust superchargers, which are fitted centrally in the V of the cylinder banks for the first time ever. By making the block more compact, this not only saves weight, but also reduces the pressure loss between intake and exhaust sides further still.
