BMW EfficientDynamics in the BMW X3.

The BMW X3 is ready for any challenge. This is especially true of its drive system. With intelligent technologies from BMW EfficientDynamics as well as its advanced energy management, it offers driving pleasure and agility, while reducing fuel consumption and emissions at the same time.


Economical BMW TwinPower Turbo engines, intelligent lightweight construction and refined aerodynamics are the ideal basis for efficiency, which is further increased by BMW EfficientDynamics technologies and options such as the eight-speed Steptronic transmission.

Intelligent lightweight construction.

A wide range of high-tech materials are used in the construction of the BMW X3, including lightweight aluminium in the front of the car and the chassis, high-strength steel in the body as well as ultra-modern plastics and magnesium. This intelligent lightweight construction reduces the weight of components and ensures outstanding body stiffness and excellent passive safety for drivers and passengers. It also improves the dynamic driving characteristics thanks to an even, well-balanced weight distribution between front and rear axles.


The BMW X3 has standard-feature technologies on board that it uses intelligently for energy coordination. This energy management is key to its high level of efficiency. Only when all these technologies interact is the vehicle able to achieve its impressive figures for fuel consumption and emissions.

The entire vehicle design is testament to the BMW EfficientDynamics philosophy. Every BMW achieves excellent air resistance figures thanks to a range of mutually optimised aerodynamic elements, which in turn have a positive effect on efficiency and fuel consumption.
For example, the flat undercarriage cover with engine compartment and rear axle shield improve the car's aerodynamics. These new casing elements not only assist aerodynamics, they also improve sound insulation and provide greater protection from rust. Further innovations in aerodynamics include the defined rear spoiler lip and the aerodynamically optimised exterior mirrors. The latter improve the acoustics as well as the aerodynamics and prevent the side windows from getting as dirty.

Aero wheels.

17-inch light alloy wheels Streamline style 306, 8 J x 17. These ‘Aero wheels’ with reduced rolling resistance 245/55 R 17 tyres, help conserve fuel and lower CO2 emissions.

ECO PRO mode.

The ECO PRO mode helps drivers reduce fuel consumption by up to 20 percent, depending on their driving style. The additional functions of Route-Ahead Assist (with Professional Navigation System only) and ECO PRO Route (with Professional and Business Navigation Systems only) can reduce fuel consumption by a further 5 percent.

Eight-speed Steptronic transmission.

The eight-speed Steptronic transmission sets a new benchmark in dynamic performance and efficiency and is a key element of BMW EfficientDynamics. The particularly finely-tuned gradation of the gears allows optimum power delivery – at both low and high speeds. This reduces fuel consumption significantly, while allowing the driver to enjoy increased sportiness and dynamic performance. At high speeds in particular, the additional gears reduce engine speed, in turn decreasing both fuel consumption and engine noise.
The converter clutch also helps – even if the car is changed to the manual mode. In combination with the fast engine speed transitions and the precise transmission tuning, it provides a very high level of shift comfort and reduces noise considerably.
