This ambiance is also particularly well designed in terms of acoustics and vibration comfort. Following the example of the work carried out on the 508, by tracking the noise to the source (acoustic "encapsulation" of the power trains), the silence on board has been significantly improved compared with the 207, while at the same time contributing to reducing the weight of the vehicle.

Finally, the atmosphere of the passenger compartment is in harmony with the rest of the vehicle: simple and sophisticated, technological and intuitive, modern and high quality.
