2021 BMW 4 Series - Interior and Exterior details

Drive systems, transmissions and BMW xDrive

The powertrain technology developed for the new BMW 4-Series Coupé is another area where significant advances have been made over the outgoing model generation, translating into a keener temperament and optimised efficiency. All the petrol and diesel engines are members of the current Efficient Dynamics family and feature the latest BMW TwinPower Turbo technology. The introduction of mild hybrid technology with a 48V starter-generator ensures even sharper power delivery combined with reduced fuel consumption and emissions. The exhaust gas aftertreatment technology has also been improved, as a result of which all model variants comply with the Euro 6d emissions standard.

For the first time, the range will be spearheaded by a BMW M440i xDrive Coupé model, which boasts outstanding performance credentials thanks to its extremely powerful six-cylinder in-line petrol engine. The new BMW 4-Series Coupé will also be available with a choice of two four-cylinder petrol units and a four-cylinder diesel from launch. The line-up is set to expand further with the arrival of two straight-six diesel engines scheduled for March 2021.

All the engines link up as standard with an eight-speed Steptronic transmission offering not just optimised efficiency and sharper shift dynamics, but also the optional Sprint function. Available for the first time, this offers an all-new way to enjoy an even sportier driving experience. BMW xDrive is available as an alternative to classical rear-wheel drive on the four-cylinder diesel model, while the intelligent all-wheel-drive system features as standard on all six-cylinder variants of the new BMW 4-Series Coupé.
