MORE AGILITY. LESS DRAG.

Aerodynamics

Good ideas don’t always have to be complicated: thanks to targeted aerodynamic measures such as air vent control, the active rear spoiler or the Air Curtain in the front apron, your BMW is able to achieve an optimised drag coefficient. This has a positive effect on efficiency and driving stability while also reducing the noise level in the cabin. See for yourself.

ACTIVE AIR STREAM KIDNEY GRILLE.

The Active air stream kidney grille knows when engine, brakes and other components need air and automatically opens the air vents. If no further air intake is required, it closes them again. This improves aerodynamics, and fuel consumption falls.

AIR CURTAIN.

While you control your vehicle, the Air Curtain controls the airstream. This is because it reduces the air resistance of the body in an astonishingly simple, yet highly effective way. Its narrowing channels speed up the airstream and guide it past the wheels. This reduces the air turbulence in the wheel housings and decreases the drag due to the body as well as the fuel consumption and CO2 emissions.

AIR BREATHER.

You accelerate. You’re moving faster and faster. But you still cannot detect any air resistance. This is because the Air Breather channels the air on the front wheels. It reduces turbulence on the wheel housings and breaks down the air swirls. Fuel consumption and CO2 emissions are decreased.

ACTIVE REAR SPOILER.

As speed increases, there is a rise in the forces acting on the body of the vehicle. At a speed of 110 km/h, the active rear spoiler extends automatically. Drag is reduced, roadholding is optimised, lift on the rear axles is decreased. In addition, fuel consumption and thus CO2 emissions are reduced. At a speed of 70 km/h, the rear spoiler retracts automatically.

AIR BLADE.

The Air Blade is a sharp-edged extension of the C-pillar that separates the air flow and thus reduces the wake behind the vehicle. This lowers the aerodynamic drag at the rear, which in turn reduces both fuel consumption and CO2 emissions.

AERO WHEEL RIMS.

An easy match against the wind: Flow-optimised aero wheel rims in Turbine styling guide the airflow optimally along the sides of the vehicle and thus enhance the aerodynamics of the vehicle.

AERODYNAMICS IN THE BMW i8.

Streamlined bodyshell, a striking conical shape, low weight – the BMW i8 clearly displays its character as a thoroughbred sports car. An array of aerodynamically optimised features ensures that maximum dynamics and optimum efficiency are achieved at the same time. One example of this can be seen in the LED rear lights created with the layering design principles and constructed as air channels through which the airstream flows.

Fuel consumption and CO2 emissions for the BMW i8 (3):
Combined fuel consumption in l/100 km: 1.9
Combined CO2 emissions in g/km: 42
Combined electricity consumption in kWh/100 km: 14.0

Economical driving. Unlimited enjoyment.

Innovative technologies such as Electric Power Steering, the ECO PRO mode or Brake Energy Regeneration jointly save energy – and thus ensure more driving pleasure. Here we present these features.

Brake Energy Regeneration.

You press down on the brake. At the same time, energy is produced. Valuable kinetic energy that can be exploited. Brake Energy Regeneration transforms it into electrical energy and uses it to charge the battery instead of letting it dissipate to no effect. Less effort is also required from the engine to charge the battery, which in turn reduces fuel consumption and emissions.

ECO PRO mode.

Concentrate on the driving pleasure. Efficiency is available at the press of a button. The ECO PRO mode permits fuel savings of up to 20%, without you having to take any action. Approximately 5% of fuel can be saved by means of additional functions. The overall saving is converted into a specific mileage and displayed as a bonus range in the on-board computer. As a result, it is possible to see what distance can still be covered at all times.

Electric Power Steering.

Conventional systems for supporting the driver’s steering power work with hydraulics. They are in permanent operation – even if the driver is not moving the steering wheel at all. And this costs energy. In the case of Electric Power Steering, an electric motor replaces the hydraulics and only becomes active when the driver actually moves the steering wheel. On straight roads or with a constant steering angle in corners, the system does not intervene and uses no energy. Fuel consumption is reduced as a result, while the typical BMW dynamic driving experience is retained.

Bonus range.

The consumption-optimised ECO PRO mode ensures that the accelerator pedal and transmission parameters together with the heating/climate control strategy are all intelligently adapted. ECO PRO tips help you to enhance your own driving behaviour and the Bonus range informs you of how many additional kilometres you have gained by driving with optimised consumption in the ECO PRO mode.

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.

    (1) The values are applicable until 15.04.2018. Please check availability with your BMW dealer.

    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 https://www.dat.de/angebote/verlagsprodukte/leitfaden-kraftstoffverbrauch.html.
