Three films have been produced as part of the Audi Sport Brandbook production. “Tunnel” focuses on the unique sound signature of the R and RS models of the brand. Each model and each available motor variant are presented in a tunnel. It’s not about racing and top speed; it is about the orchestration of ignition sequences and engine sounds. Each one unique and different, all connected by the goose bumps they create. The film plays with the counterpoint between stillness and the powerful sound of the motor.
