Optimised aerodynamic design

 

Zoom

Special attention has been paid to the aerodynamic, flowing lines – strong Citroën values. The drag coefficient is 0.26 and rear lift 0.02.


In addition to styling and volume that enhance air penetration, various technological features contribute to that result:

  • air ducts on both sides of the front bumper. They produce an air flow through the front wheel arches, creating a virtual fairing.
  • an electro-mechanical system at the rear of the roof. It consists of micro electro-mechanical systems (MEMs), which create a virtual airfoil by propelling jets of air and substantially improve the vehicle's drag and stability at high speeds.
  • a reverse mobile airfoil, under the structure at the rear of the vehicle. This cylinder-activated reverse airfoil improves lift and enhances vehicle stability at high speeds. It has three positions:

Zoom

- a "neutral" position, integrated with the rear styling, when the vehicle is stationary or in the city;
- a position adopted at a cruising speed of above 90 kph that optimises the drag coefficient and lift.
- a position activated during emergency braking to increase negative lift by adding support and stabilising the vehicle.

  • the smooth subframe improves both drag and positive lift by optimising air flow under the vehicle.

This capacity to penetrate the air enhances the C SportLounge's efficient, dynamic handling, performance and environmental-friendliness
