The laminated acoustic front windows add to the vehicle's cocoon effect. Passengers are comfortably seated, shielded from the outside. Citroën brings light into the passenger compartments so passengers are immersed in a bubble of light from the roof. In ZEV mode, in generally the most stressful driving situations in cities or on short journeys, the acoustic comfort of Citroën vehicles is increased. No vibrations disturb the peace on board.
