The Mercedes SLS AMG was first used as a Safety Car back in 2010 shortly after its official debut. Now, for the 2012 racing season, the SLS is returning as the Official F1 Safety Car. The Safety Car is based on the standard SLS AMG, with absolutely no changes made to the standard 571 HP 6.3-liter V8 engine, or its suspension and braking system.
What Mercedes did do was add a newly developed exhaust – designed to provide an even more emotionally-charged sound experience - as a tribute to the Formula 1 fans. Next to this, the Safety Car also received a roof light bar that boasts an aerodynamically efficient profile. The bar’s light functions are handled by LEDs which offer a fast response time and low power consumption. The colors change to green when the Formula 1 drivers can overtake the Safety Car or orange when no overtaking whatsoever is allowed. The roof light bar also incorporates a TV camera and a second camera located next to the rear number plate that allows the driver and co-driver to keep an eye on the Formula 1 cars.
The interior of the Mercedes SLS AMG Safety Car is almost identical to the production car, except of course for the two central monitors placed in the cockpit, which are used to monitor the progress of the race.
