The second series of 4-cylinder cars lasted just a few years. Production of the new 200, 200D and 230 models commenced in July, 1965, at the Sindelfingen plant. The 200 and 200D replaced the 190c and 190Dc models respectively. The engine in the 200 had the bore increased from 85 to 87 mm, giving a 1988 cc displacement, and was fitted with twin carburetors (the 190c had a single carburetor). The OM621 diesel engine in the 200D was essentially identical to that of the 190Dc (which was actually a 1988 c.c. unit despite the car being labelled as a '190') but was improved by using a five main bearing crankshaft instead of the original three.
