The 2012 SLS AMG Roadster offers an Airscarf system that acts like an invisible scarf warming the head and neck areas of the occupants. It is integrated into the backrests of the AMG sports seats, and blows warm air from vents in the head restraints.
The seven-speed sports transmission of the 2012 SLS AMG Roadster boasts fast gear changes with no loss of tractive force--in as little as 100 milliseconds. It also offers four driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) or "M" (Manual).
The design of the SLS AMG Roadster creates the lowest possible center of gravity. This applies both to the low connection points of the power train and axles, as well as to the arrangement of the rigid bodyshell structure, which has been kept as low as possible.
