Based on the limited production CLK GTR, the Super Sport is the top echelon of Mercedes-Benz products. It is the product of HWA, a specialist firm which helped Mercedes-Benz prepare the original CLK GTRs that raced the GT1 class at Le Mans. HWA is also responsible for creating the 25 road going examples of the GT1 racecar. Among these HWA has prepared five roadsters and two even more limited super sports models having a much larger engine.
