The efficiency of the BMW X5.

There are several reasons for the power and efficiency of the BMW X5: fuel-saving petrol and diesel engines, sophisticated aerodynamics – and a whole range of other BMW EfficientDynamics measures.

With BMW EfficientDynamics, BMW combines efficiency and driving pleasure with the aim of approaching the ultimate goal of zero-emissions mobility.

It has enabled the BMW Group to reduce the CO2 emissions of its European fleet of new cars by 30% since 1998, with a further 25% reduction anticipated by the summer of 2020. As of summer 2013 there are already 22 BMW models under 120g CO2/km. Our cars’ intelligent energy management and lightweight construction, as well as improvements in aerodynamics and engine efficiency all combine to make sustainable mobility a reality even today.

Every BMW features the very latest BMW EfficientDynamics technologies. These include BMW TwinPower TurboTechnology, the Auto Start-Stop function and the ECO PRO Mode. Our research also focuses on the development of innovative engine technologies such as BMW ActiveHybrid and BMW eDrive technology, as well as the BMW Hydrogen 7 with hydrogen drive.

Inspired by the EfficientDynamics philosophy, BMW i develops visionary new vehicle concepts based on electromobility, such as the BMW i3 (Megacity Vehicle) and the BMW i8. As well as featuring many existing BMW EfficientDynamics technologies, these vehicles also benefit from innovations in intelligent lightweight construction, such as the use of carbon. Our engineers’ talent for innovation has brought about a reduction in fuel consumption and emissions and a simultaneous increase in performance and driving pleasure − all of which makes every drive in your BMW even more enjoyable.


In the BMW Concept X5 eDrive, the innovative EfficientDynamics drive technology BMW eDrive and the intelligent all-wheel drive system BMW xDrive are united for the first time. The combination of a BMW TwinPower Turbo 4-cylinder combustion engine and a 70 kW (95 hp) electric motor provides typical BMW driving pleasure, with BMW xDrive further increasing the dynamics. At the same time, this dynamic duo is impressively efficient: The average consumption of less than 3.8 l/100 km in the EU test cycle is unrivalled among vehicles in this class, with CO2 emissions of less than 90 grammes per kilometre also setting new standards. Via the driving modes, the drive characteristics can be regulated individually. In the fully electric mode, which is free from local emissions, a range of up to 30 km is possible – at speeds of up to 120 km/h.

  • Perfect for day-to-day requirements.

    The BMW Concept X5 eDrive obtains its electrical energy from a (lithium-ion) high-voltage battery, which is accommodated in a space-saving manner under the flat luggage compartment floor. This means that the room in the vehicle can still be used flexibly, with an almost identical luggage space volume. The high-voltage battery can be charged quickly and conveniently using the BMW Wallbox. Alternatively, it can be replenished using any standard household power outlet or at a public charging station.
    On the exterior, design features such as kidney grille slats and air inlet supports in the specially developed BMW i Blue finish as well as aerodynamically optimised 21-inch light-alloy wheels provide a striking contrast to the Silverflake metallic body colour.


As soon as you switch to the ECO PRO Mode, everything is geared towards greater efficiency and depending on your individual driving style, this results in a reduction in fuel consumption of up to 20 per cent (according to an internal BMW fuel consumption study).


Another five per cent can be saved by the additional functions of coasting, preview assistant and ECO PRO Route. This mode optimises accelerator and transmission response as well as shift points, and intelligently adapts the heating/air conditioning strategy. The Control Display shows you which EfficientDynamics technologies are currently lowering your fuel consumption. You’ll also receive ECO PRO tips that relate to your current driving situation to help you boost efficiency even further.


Another feature of the ECO PRO mode is the coasting function: If no driving power is required within a speed range of 50 km/h to 160 km/h, the system disconnects the engine and the car coasts.


The preview assistant in conjunction with Navigation System Professional is an especially innovative highlight of ECO PRO mode. Based on navigation data, it detects bends, built-up areas, roundabouts, T-junctions, speed limits and motorway exits along the route and is able to give you tips in advance to enable you to reduce speed early on.


ECO PRO mode also includes ECO PRO Route which combines with the new generation of Navigation system Professional to draw on various parameters such as individual driving style as well as the current traffic situation and road conditions to calculate the most fuel-efficient route. The on-board computer displays your bonus mileage, in other words how many additional kilometres you have gained from using ECO PRO mode.


The entire vehicle design is testament to the BMW EfficientDynamics philosophy. The optimised, aerodynamic front apron and undercarriage feature innovative improvements that reduce air resistance and fuel consumption.

  • Air Curtain and Air Breather

    The front apron is a prominent design feature that embodies the BMW EfficientDynamics philosophy. The integrated Air Curtain channels air through two vertical air inlets and along the front wheel arches. The accelerated air flow creates a kind of "curtain" on the outer side of the wheels. Then there’s the Air Breather, which channels the air flow at the front wheels. These innovative technologies reduce turbulence and air resistance, which in turn reduces fuel consumption.

  • Air vent control

    The automatic air vent control uses a sensor to continuously assess the current cooling needs of the engine and opens or closes the radiator air vents in response. This optimises aerodynamics and shortens the warm-up phase for reduced fuel consumption.

  • Rear spoiler and Air Blade

    The rear spoiler at the roof edge and the Air Blades joined to it at the sides go together to form a highly efficient so-called "trailing edge". The precisely defined air flow at the rear reduces disruptive air swirl and the braking effect of negative pressure to a minimum.


The BMW X5 sDrive25d is the most efficient version of the model range. Rather than all-wheel drive, the BMW X5 sDrive25d has rear-wheel drive. It is not least the weight benefit deriving from this that gives it such low fuel consumption and emission levels. With 160 kW (281 hp), the BMW X5 sDrive25d offers a dynamic drive – with a fuel consumption of a mere 5.6 litres per 100 kilometres. Despite this fuel efficiency, it can accelerate from 0 to 100 km/h in an impressive 8.2 seconds.
