Add-on parts

Add-on parts such as wheel spoilers help to achieve aerodynamic objectives and therefore must be carefully optimised.

The flared wheel housings and wider tyres mean that the wheel spoilers for the front and rear wheels have had to be redesigned and optimised. The optimised wheel spoilers shield the wheels from the air flow in an effective manner and encourage the air coming from the front and the underbody to flow past the tyres aerodynamically. This guarantees a low-resistance air flow around the wheels and reduces the overall drag coefficient. In addition, the optimised wheel spoilers and further add-on parts on the underbody influence the lifting forces in such a way as to achieve the desired aerodynamic lift balance.







New to the 911 Carrera is a front spoiler on the front lower part which further reduces lift at the front axle as well as aerodynamic linings on the trailing link and control arm at the rear axle which also help to achieve the aerodynamic objectives for lift and resistance.

Conclusion
The excellent aerodynamic coefficients achieved have further strengthened the position of the 911 Carrera in its segment. On top of this drag (Cw x A ) has actually been reduced in comparison with the previous model, despite a larger frontal area. The optimised aerodynamics of the 911 Carrera therefore help to improve driving dynamics, performance and fuel economy.
