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.

Optimum Shift Indicator
Choosing the right moment to change gear is a key to efficiency. The most efficient gear at any point in time is calculated according to the driving situation together with the engine speed and then shown in the Info Display.
The system also recognises rapid acceleration and will delay its recommendation accordingly until the engine speed is up. Comparative tests have shown that vehicles with the Optimum Shift Indicator use around four per cent less fuel.
Automatic Start/Stop function
Save fuel effectively: The Automatic Start/Stop function ensures that fuel is only consumed when the car is moving. When the vehicle comes to a temporary stop, for example at traffic lights or in congested traffic, the Automatic Start/Stop function saves fuel by simply switching off the engine. As soon as the clutch is depressed (manual transmission) or the brake is released (Steptronic transmission), the engine starts up again automatically in a fraction of a second.
Tyres with reduced rolling resistance
On the motorway. In the city. Everywhere. Wherever you drive – your tyres are constantly subjected to powerful forces during driving. During contact with the road, their shape changes. This deformation is only reversed when there is no more road contact. Tyres with reduced rolling resistance employ special materials to reinforce the tread and sidewalls which decrease flexing compared to conventionally designed tyres – and this noticeably reduces fuel consumption and emissions.
