The distinctive gullwing doors open to reveal a practical cockpit which, like the exterior, differs only slightly from that of the standard-production model. AMG sports bucket seats with black leather upholstery and six-point seat belts ensure optimum lateral support. On the right side of the AMG DRIVE UNIT, there are four colored buttons for controlling the various light functions, along with the signal horn, which is activated when the car is driving into and out of the pit lane. The centre console, like various other interior trim parts, is finished in genuine carbon fiber, while the AMG performance steering wheel in leather/Alcantara features a specially shaped grip area, a high-quality genuine-metal insert and a flat-bottomed rim with a diameter of 370 millimeters. Two genuine-metal shift paddles are used to change between the seven gears in the double-clutch transmission.
Two central monitors in the SLS AMG cockpit are used to monitor the progress of the race. To the left and right of the lower monitor are the controls for the radio system, which allows Bernd Mayländer and Pete Tibbetts to communicate with Race Control as well as with each other. A second interior mirror lets the co-driver keep an eye on the Formula-1 cars behind. Meanwhile, the "Marshalling System" is integrated in the central display on the instrument cluster and in the lid of the glove compartment: here the driver and co-driver can see exactly the same signals as the Formula-1 drivers in their cockpits. For instance, the various LEDs indicate when yellow or green flags are being waved. LEDs indicating the status of the roof light bar, along with an on-board camera angled towards Bernd Mayländer, are mounted at the front end of the dashboard.
