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.

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.
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.
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
