The engineers also focused on the sound of the vehicle. In every driving situation, the driver and front passenger hear a tailor-made driving noise: dynamic when accelerating, muffled when driving smoothly and just as typical during recuperation. The sound varies depending on the driving speed, engine speed and load status. Perfect feedback to the driver is provided by a combination of composed sound, the vehicle's own noise and eliminated background noise. The sound system consists of eleven loudspeakers as standard.
