BMW EfficientDynamics in the BMW X4.

    Restraint is not an attribute usually associated with the BMW X4 – with one notable exception: fuel consumption and CO2 emissions. The latest BMW EfficientDynamics technologies and an aerodynamic design guarantee low values without any compromise in performance and dynamics.

    The entire vehicle design is testament to the BMW EfficientDynamics philosophy. Every BMW boasts excellent air resistance figures thanks to a range of mutually optimised aerodynamic elements, which in turn has 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 are not only highly advantageous in terms of 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 in addition to the aerodynamics and prevent the side windows from getting as dirty.


    A wide range of high-tech materials are used in the construction of the BMW X4: lightweight aluminium, high-strength steel, state-of-the-art plastics and magnesium.
    This intelligent lightweight construction reduces the weight of the vehicle, makes the car body exceptionally rigid, enhances passive safety and improves dynamics.


    ECO PRO Mode helps drivers to reduce their fuel consumption by up to 20 per cent, depending on their driving style – according to an internal BMW fuel consumption study. Further savings potential can be achieved through coasting (with 8-speed Steptronic transmission only), Route-Ahead Assistant and ECO PRO Route (both with Navigation system Professional only).

    The 8-speed Steptronic transmission sets a new benchmark in dynamic performance and efficiency and is a key element of BMW EfficientDynamics .
    The unusually fine increments between gears facilitate optimum power delivery at all 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.
    Thanks to the 8-speed Steptronic transmission from BMW EfficientDynamics , it is now possible to actively boost performance in vehicles with the new Predictive Drive Train via the Driving Experience Control. In the "Sport" mode, the transmission management uses data from the navigation system to deliver a level of responsiveness that is even more dynamic and spontaneous based on route characteristics. As suggested by its name, the "Comfort" mode offers a comfort-oriented shift programme with fewer shifts.


    The intelligent energy management in the BMW X4 is provided by a number of standard-feature BMW EfficientDynamics technologies, including the Optimum Shift Indicator, the Auto Start-Stop function, Electric Power Steering and Brake Energy Regeneration. The interplay between these technologies ensures the sustainable mobility of tomorrow − today.
