The interior is trimmed in soft leather. Bose audio system and a navigation system were standard. In typical Porsche fashion, the ignition is present to the left of the steering wheel. This placement dates back to the early days of Le Mans racing when drivers were required to make a running start, hop into their cars, start them and begin the race. The placement of the ignition enabled the driver to start the car with the left hand and put it in gear with the right. Originally, the car had a beech wood gearknob, which pays homage to the wooden gearknob used in the 917 Le Mans race car. In its second year of production, a carbon fibre knob was also made available.
