BMW xDrive intelligent all-wheel drive takes traction, directional stability and agility to even greater heights. The system is fitted as standard in the range-topping model BMW M440i xDrive Gran Coupé and is available for the 420d diesel model as an alternative to classical rear-wheel drive.
Mild hybrid technology is included with the straight-six petrol and diesel engines. A 48V starter-generator acts like an electric drive unit that assists the engine, allowing it to operate within an efficiency-optimised load range as much as possible. An electric boost effect is also offered, which adds an extra 11hp to give the power unit an even sharper response.

A six-cylinder in-line unit powers the BMW M440i xDrive, which has been developed with racetrack expertise. It generates a maximum output of 374hp with torque peaking at 500Nm, enabling the car to sprint from 0-62mph in just 4.7 seconds, all complemented by the distinctive-sounding standard M Sport exhaust system.
BMW 420i and 430i
The upgraded BMW TwinPower Turbo technology enhances the performance of the 2.0-litre four-cylinder petrol engines. The more powerful of the two generates 245hp and a peak torque of 400Nm, enabling it to accelerate to 62mph from standstill in only 6.2 seconds. The four-cylinder engine in the 420i produces 184hp and a peak torque of 300Nm, launching it from 0 to 62mph in 7.9 seconds.
