A core element of BMW EfficientLightweight in the BMW 7 Series is to use an innovative mixed construction for the body. Using steel, aluminium and in particular innovative carbon fibre (carbon fibre–reinforced plastic, CFRP) not only meets all the requirements for driving dynamics and comfort, but also sets whole new standards in the luxury class.
At the centre of the holistic concept stands the Carbon Core, showcasing its weight advantage compared with steel in the torsional stiffness of the body. Together with a consistent weight reduction from the broad concept down to the smallest detail, this achieves an almost perfect 50:50 axle load distribution and drops the centre of gravity even further. In short, this spells out the ideal car DNA for maximum driving comfort while still boasting an improvement in handling and agility as well as low fuel consumption and emissions.
In this way, BMW EfficientDynamics intelligently connects the ultimate in efficiency with maximum driving dynamics, and demonstrates its technological capabilities in the field of innovative lightweight construction.


Aerodynamics are an important area and play a crucial part in optimising the countless demands made of a vehicle - like air resistance, driving stability and acoustics.
In terms of BMW EfficientDynamics, the most crucial role is played by air resistance, and therefore also the so-called drag coefficient as a measure for streamlining. This is determined to 40% through the proportions of the body, 20% through the undercarriage, 30% through the wheels and wheel arches and 10% through the functional apertures. Wheel arches and functional apertures offer the most effective areas for optimisation, since the basic form is determined to a large degree by vehicle design and the undercarriage is already completely clad.
Air resistance is most markedly reduced by the Air Breather and the Air curtain on the front wheel arches as well as the Active air stream kidney grille with its visible air vents between the grille slats to electrically open and close the air inlet in front of the radiator when needed. Additionally, the 2-axle air suspension automatically lowers the vehicle by 10 mm at speeds over 120 km/h, further reducing air resistance. Air resistance on this vehicle has been reduced by up to 10 % thanks to developments made to the previous model.

  • Active air stream kidney grille

    The Active air stream kidney grille represents the cutting edge of aerodynamic performance. When a cooling airflow is not needed, it electronically closes the radiator grille with its air vents and thereby reduces the amount of air flowing into the engine bay. This optimises both the aerodynamics and consumption rates.

  • Air Curtain

    The Air Curtain reduces drag on the bodyshell in a very simple, but extremely effective way. Two narrowing channels guide the airstream through the front apron and past the wheels. This reduces the air turbulence in the wheel housings, which decreases fuel consumption and CO2 emissions. A further benefit of the Air Curtain is that it contributes to improved cooling of important vehicle components.

  • Air Breather

    The Air Breather is located behind both front wheel arches and is one of the innovations used to optimise the vehicle's aerodynamics. Together with the Air Curtain in the front apron, the Air Breather greatly reduces turbulence and accurately channels the air flow. This decreases air resistance, thereby reducing the vehicle’s fuel consumption and CO2 emissions.

  • Aero wheels

    Perfect aerodynamics for optimising fuel consumption doesn’t begin and end with the bodyshell. In and around a vehicle’s wheels and rims, the rotational movements of the spokes often cause air turbulence which stands in the way of perfect airflow. The new resistance-optimised Aero wheels in turbine design developed by BMW counter this turbulence effectively, channelling the air along the sides of the vehicle to the optimum. This lowers wind resistance while at the same time reducing emissions and increasing driving pleasure.

BMW 730d/Ld.

The BMW 730d/Ld with TwinPower Turbo inline 6-cylinder diesel engine from the new generation of BMW EfficientDynamics engines displays commanding driving performance and low fuel consumption. It delivers an impressive torque of 620 Nm and a maximum output of 195 kW (265 hp). The combined fuel consumption rate is just 5.0 to 4.5 litres per 100 km (5.2 to 4.8 litres per 100 km with xDrive), with low average CO2 emissions of 132 to 119 g/km (137 to 127 g/km with xDrive). Equipped with this engine, the BMW 730d/Ld takes just 6.2 to 6.1 seconds for the sprint from 0 to 100 km/h (5.9 to 5.8 seconds with xDrive) and reaches a top speed of 250 km/h. The aluminium lightweight construction 3.0 litre diesel engine inspires with its great performance, incredible power delivery and top-notch responsiveness at all engine speeds. It combines CommonRail direct injection and a one-stage turbocharger with variable turbine geometry.



The 8-speed Steptronic transmission sets new benchmarks in comfort and dynamic performance 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. The engine speed is reduced, particularly at high speeds, which in turn reduces both fuel consumption and engine noise.
The converter clutch also helps – even if the car is changed to the manual mode. The fast engine speed transitions and precise transmission tuning guarantee incredibly smooth gearshifts.
Integrated functions – such as the predictive drivetrain, the constant monitoring of the vehicle's movements and the traffic situation – considerably affect the way the transmission shifts gears. Regardless of the current driving mode, the system always selects the most suitable gear. The transmission control unit is linked to the navigation system, so depending on the route, the predictive drivetrain switches between a more athletic, responsive setting (SPORT mode) and a more comfortable setting with fewer gear shifts (COMFORT mode).


The intelligent BMW xDrive all-wheel drive system adapts perfectly to even the most challenging road surface conditions, ensuring optimal traction at all times. xDrive and Dynamic Stability Control (DSC) ensure that the BMW remains safe and stable. Controlled via the DSC sensor system, xDrive flexibly and quickly distributes drive power between the axles in order to prevent oversteer or understeer on bends, thereby ensuring outstanding directional stability. Moreover, it guarantees a rapid, safe acceleration even on slippery or steep stretches. In critical road conditions, the DSC doesn't need to intervene as much. Thus, BMW xDrive combines all the advantages of an all-wheel drive system – traction, directional stability and driving safety – with classic BMW agility.


Standard features of the intelligent energy management in the BMW 7 Series include the BMW EfficientDynamics technologies Automatic Start/Stop function, Brake Energy Regeneration and electric power steering. These technologies working together ensure sustainable mobility and maximum efficiency.
The illustrations shown here are subject to change.

  • Automatic Start/Stop function

    The Automatic Start/Stop function ensures that fuel is only used when the car is actually moving. When the vehicle comes to a temporary standstill, for example at traffic lights or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the driver brakes the car to a complete standstill. This reduces fuel consumption by up to 6%.
    A signal in the Info Display indicates that the Automatic Start/Stop function is active. As soon as the driver removes their foot from the brake pedal, the engine starts again automatically.
    This function never compromises driving comfort or safety, as it remains inactive if the engine has not reached its optimal running temperature, the interior has not yet been sufficiently heated or cooled, if the battery level is too low or if the steering wheel is being turned. If necessary, a central control unit restarts the engine even when at a standstill, for example if the car begins to roll or if condensation starts to form on the windscreen. The Automatic Start/Stop function can be switched off at any time with the push of a button.

  • Brake Energy Regeneration

    Every braking process generates kinetic energy; and until recently this energy went unused. Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever the driver brakes or takes their foot off the accelerator, and turns it into electricity. This electricity is then used to charge the car battery. This intelligent energy management system means that the alternator no longer needs to run constantly, which reduces the strain on the generator. The result: reduced fuel consumption and increased propulsion power – classic attributes of BMW EfficientDynamics.

  • Electric power steering

    Electric power steering optimally adjusts the steering support to the current speed. This results in direct, precise steering behaviour at high speeds and effortless manoeuvrability when parking. The steering only consumes energy when it is really necessary. This saves fuel and reduces emissions.
    Instead of a hydraulic pump, it relies on an electric motor. In conventional systems, this pump must be constantly powered by the engine, but this electric support only runs when the steering wheel is being moved. When driving straight ahead or maintaining the same steering angle (e.g. on long bends), the electric motor is not active and does not consume any energy. By flexibly adjusting the steering support to match the current driving situation and speed, steering comfort is improved.


The Driving Experience Control offers the driver the choice between the standard COMFORT mode, ECO PRO Mode, geared towards efficiency, and SPORT mode, which enables even more dynamic driving. The new interactive Adaptive Mode function continuously adjusts the adaptive suspension, the steering and the Steptronic transmission to suit the current driving situation.

  • Coasting

    The "coasting" function allows the vehicle to coast along the road at up to 160 km/h when the driver takes their foot off the accelerator without braking.

  • Route-ahead assistant

    The Route-ahead assistant uses the navigation system to assess local road conditions and give tips in advance. If there is a speed limit change around the next bend, the system advises the driver to slow down before the bend.

  • ECO PRO route

    ECO PRO route also helps to ensure the efficient use of fuel. It suggests an efficiency-optimised route that takes into account the volume of traffic, individual driving style and local conditions.

  • Adaptive Mode

    Adaptive Mode is an intelligent and interactive function in Driving Experience Control. The Adaptive Mode influences the Dynamic Damper Control, the steering and Steptronic transmission and continually adapts the settings to suit the current driving situation independent of the selected driving mode (COMFORT/SPORT).

    When in Adaptive Mode, the system takes account of numerous indicators such as kickdown, steering wheel movements and cruise control, along with the driver's individual style of driving. Furthermore, the system also relies on interaction with real-time navigation to adjust the suspension control in preparation for bends, intersections or different road conditions. In addition to Adaptive Mode, the driver can also select the SPORT, COMFORT or ECO PRO modes.
