Mercedes Benz 220a (W180)
Introduced in March 1954, the 220a was a more luxurious and up-scale version of the W120 model 180. Their wheelbase was stretched by 170 mm (6.7 in). 100 mm (3.9 in) of that increase in length was to accommodate the longer straight-6 M180 engine taken from the W187 model 220. In this application it delivered 85 PS (63 kW; 84 hp) fed by a single carburetor. The passenger cabin was also lengthened by 70 mm (2.8 in) to provide an increase in the leg room for rear seat passengers. 220a production ended in April, 1956 with 25,937 units produced.
Mercedes Benz 220S (W180)
The 220a was succeeded in March 1956 by the 220S, which was externally almost identical, but had an upgraded version of the 2.2L inline-six (100 PS (74 kW; 99 hp), later 106 PS (78 kW; 105 hp)), due to the use of twin-carburetors. The 220S also featured a new one piece front bumper, solid chrome strips under the doors, and a chrome strip running along the front fenders and doors of the 220S.
The 220S sedans came with a 4-speed column shift manual transmission, and an optional Hydrak automatic clutch. This made use of small micro-switches on the gear selector that automatically disengaged the clutch when the driver changed gears.
In July 1956 a Cabriolet (two doors, four seat) joined the line-up, and in October 1956 a Coupé version followed suit. Some Cabriolets were finished with folding rear seats to accommodate additional luggage.
