This 1959 Mercedes 220S is a Semi-Automatic, aka "Hydrak" which in German stands for "hydraulische kupplung" (hydraulic coupling). It was a factory-original, extra cost option and there is no clutch pedal. Instead, the hydraulic clutch engages by you touching the shift lever which is triggered electronically (German Engineering!). It's very comfortable, especially in rush hour traffic. Non of the Mercedes 220S Ponton of that period have power steering, hence the large steering wheel.
