The Mercedes-Benz 230 SL (W 113) is presented at the Geneva Motor Show to replace the 300 SL and 190 SL sports cars. This is the world's first sports car to feature the safety bodywork developed by Béla Barényi. Its hardtop has a concave roof line which leads to it being called the "Pagoda SL". The new SL is the first Mercedes-Benz car fitted with a dual-circuit brake system as standard. Another new product on show in Geneva is a version the 300 SE with 10-cm-longer wheelbase, which establishes the tradition of long-wheelbase S-Class saloons.
