SMALL DETAILS, BIG BENEFIT.
Good ideas don’t always have to be complicated: impressive positive effects for greater efficiency can be achieved via intelligently-implemented measures and simple improvements to the aerodynamics.
ACTIVE REAR SPOILER.
- Problem: High speeds generate buoyancy forces that affect adhesion and agility.
- Solution: The rear spoiler extends according to the speed and optimises the buoyancy coefficient on the rear.
- The benefit to you: Consumption decreases, the lift on the rear axle and the agility typical of BMW improve.
- Problem: Turbulence in the front wheel housings increases aerodynamic drag on the vehicle.
- Solution: An air outlet behind the front wheel channels the incoming air and reduces air currents in wheel housing.
- The benefit to you: Thanks to the improved aerodynamics, fuel consumption and CO2 emissions decrease.
- Problem: The wheel housings drastically increase vehicle drag.
- Solution: Narrowing channels speed up the airstream and guide it along the wheel housings.
- The benefit to you: The vehicle’s drag is reduced – and with it fuel consumption.
- Problem: High aerodynamic drag occurs in the region known as the wake behind the rear of the vehicle.
- Solution: The Air Blade, a sloping edge on the C pillar, reduces the wake.
- The benefit to you: The improvement in aerodynamics behind the rear reduces fuel consumption and CO2 emissions.
AERO WHEEL RIMS.
- Problem: Wheel housings and wheels create approx. 30 % of the vehicle’s total drag.
- Solution: Flow-optimised wheels.
- The benefit to you: Improved vehicle aerodynamics and increased efficiency.
AIR VENT CONTROL.
- Problem: Permanently opened air inlets increase the vehicle’s drag.
- Solution: Automatically-controlled air vents that only open when needed.
- The benefit to you: Aerodynamics improve when no air flow is required, thus lowering consumption.
