The new BMW X4 M40i.

BMW MPerformance

Where maximum performance is concerned, it is often small details that make a great difference. The new BMW X4 M40i demonstrates this with performance and agility that allow you to master even difficult driving situations with ease. Primarily responsible for this self-assuredness is the 355 hp 365 lb-ft M Performance TwinPower Turbo 6-cylinder petrol engine, the innovative lightweight construction and the Adaptive M suspension.

Keeping up has never been so difficult – for the rivals. This is because the M Performance TwinPower Turbo inline 6-cylinder petrol engine pulls away with 355 hp thanks to the twin-scroll turbocharger the fully variable Valvetronic valve control and High Precision Injection high-pressure direct injection. This provides a maximum torque of 365 lb-ft, acceleration from 0 to 100 km/h in 4.8 seconds – and above all an even greater lead over the competition.

The driving dynamic features of the BMW X4 M40i.

Facing new challenges always calls for the best possible preparation. This is why the BMW X4 M40i appears in absolute top form. The especially precise M Sport suspension and the variable sports steering provide extremely precise handling. The M Sport brakes as standard, the BMW xDrive all-wheel drive system and the M Sport differential increase the lateral and longitudinal dynamic properties of the vehicle. As if created to set new standards.


The driving dynamic features of the BMW X4 M40i.

  • Adaptive M suspension

    The Adaptive M suspension can be electronically adjusted at any time to suit the road and driving conditions. The driver can also adjust the suspension characteristics via the Driving Experience Control to enable their preferred driving style at the time – from comfortable to extremely athletic with markedly agile handling.

  • Variable sport steering

    The Variable sport steering with Servotronic creates a direct and agile steering response and ensures that less physical effort is required to turn the wheel. It reacts to the angle of the steering wheel with varying steering ratios. This improves handling when driving more dynamically and reduces the effort needed to steer when parking and turning.

  • BMW xDrive including M Sport differential

    The intelligent BMW xDrive all-wheel drive system smoothly and variably distributes drive power to the front and rear wheels for maximum traction, driving dynamics and safety in every driving situation. For even better agility, the electronically controlled power distribution for instance counterbalances oversteer or understeer on bends. The M Sport differential optimises traction and driving stability when driving dynamically or on different road surfaces.


The M Performance specific design features underline the exclusivity of the BMW X4 M40i at the very first sight. Enlarged air inlets, kidney grille and mirror caps in Cerium Grey are a clear statement of the sporty ambitions. Guaranteeing the strong appearance are 21” light alloy wheels, while exclusive free-form tailpipes in Black Chrome leave a lasting impression behind.


The M Sport package supplied as standard lends the BMW X4 M40i a dynamism that continues throughout the entire interior. From the M leather steering wheel and M Performance specific instruments, via interior trims to the M footrests – it provides athleticism down to the finest detail.

Outstanding in function and design.

The individually adjustable Sport seats for the driver and front passenger feature numerous manual adjustment options, including backrest width, fore-and-aft position, and the backrest and seat angle. Thanks to taller seat and backrest bolsters, and well-defined side bolsters, they provide excellent ergonomics and a high degree of lateral support.

Sporty characteristics with charisma.

The centre console is equipped with a coloured M badge instead of the series designation in the front area, which emphasises the sporty atmosphere in the interior and points to the driving dynamics qualities of the vehicle.

Fuel consumption and CO2 emissions.

  • The values of fuel consumptions, CO2 emissions and energy consumptions shown were determined according to the European Regulation (EC) 715/2007 in the version applicable at the time of type approval. The figures refer to a vehicle with basic configuration in Germany and the range shown considers optional equipment and the different size of wheels and tires available on the selected model.

    The values of the vehicles labeled with (2), are preliminary.

    The values of the vehicles labeled with (3), are already based on the new WLTP regulation and are translated back into NEDC-equivalent values in order to ensure the comparison between the vehicles. [With respect to these vehicles, for vehicle related taxes or other duties based (at least inter alia) on CO2-emissions the CO2 values may differ to the values stated here.]

    The CO2 efficiency specifications are determined according to Directive 1999/94/EC and the European Regulation in its current version applicable. The values shown are based on the fuel consumption, CO2 values and energy consumptions according to the NEDC cycle for the classification.

    For further information about the official fuel consumption and the specific CO2 emission of new passenger cars can be taken out of the „handbook of fuel consumption, the CO2 emission and power consumption of new passenger cars“, which is available at all selling points and at
