Mercedes Benz 220 S

.

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-carburettors.
Visually, the 220S featured a new one piece front bumper, instead of the 3-piece bumper used on the 220a. Also, the twin chrome and rubber strips running under the doors of the 220a were replaced with solid chrome strips. The most obvious difference is the addition of a chrome strip running along the front fenders and doors of the 220S.
