The W113

The Mercedes-Benz W 113 is a two-seat roadster/coupé, introduced at the 1963 Geneva Motor Show, and produced from 1963 through 1971. It replaced both the 300 SL (W 198) and the 190 SL (W 121 BII). Of the 48,912 W 113 SLs produced, 19,440 were sold in the US. 

The W113 SL was developed under the auspices of Mercedes-Benz Technical Director Fritz Nallinger, Chief Engineer Rudolf Uhlenhaut and Head of Styling Friedrich Geiger. The lead designers were Paul Bracq and Béla Barényi, who created its patented, slightly concave hardtop, which inspired the "Pagoda" nickname.

All models were equipped with an inline-six cylinder engine with multi-port fuel injection. The bonnet, boot lid, door skins and tonneau cover were made of aluminum to reduce weight. The comparatively short and wide chassis, combined with an excellent suspension, powerful brakes and radial tires gave the W 113 superb handling for its time. The styling of the front, with its characteristic upright Bosch "fishbowl" headlights and simple chrome grille, dominated by the large three-pointed star in the nose panel, paid homage to the 300 SL roadster.

W 113 SLs were typically configured as a "Coupe/Roadster" with a soft-top and an optional removable hardtop. A 2+2 was introduced with the 250 SL "California Coupe," which had a fold-down rear bench seat instead of the soft-top.
