Mercedes-Benz W110

The W110 is a line of mid-size primarily inline four-cylinder executive cars produced by Mercedes-Benz between 1961 and 1968. The company's basic line of for much of the 1960s, it was part of Mercedes' unified platform of "Fintail" models – first introduced as a six-cylinder Mercedes W111 in 1959.

The 190c and 190Dc sedans debuted in April 1961, replacing the W120 180c/180Dc and W121 190b/190Db. The gasoline-powered 190c was fitted with the 1.9 L M121, an upgrade from the 1.8 L M136, and the 190Dc the 2.0 L OM621 diesel, an upgrade from the obsoleted 1.8 L OM636.

The W110 line was refreshed in July 1965, with an engine displacement increase to 2.0 litres and a second carburetor giving more power to the new gasoline 200 model that replaced the 190, and an improved already 1988 cc diesel fitted in the new 200D that replaced the 190Dc.

The W110 range gained a new model, the 230, a downscaled version of the 6-cylinder W111 220S (with the commensurate new 230S replacing the W111 line's 220Sb and 220SEb).

Production of the W110 lasted just three more years, until the W114 '220' and W115 '220D' introduced in 1968.

Second series (1965–1968)

The second series of 4-cylinder W120/W121 cars, the new 200, 200D and 230 models, commenced in July, 1965, and lasted two and one-half years. The 200 and 200D replaced the 190c and 190Dc models respectively, and a new 6-cyclinder 230 model was added to the line, a bored out W111 220b.

The 200 received an enlarged version of the 1897 cc M121 gasoline engine, bored out from 85 to 87 mm, to 1988 cc, given a second carburetor, and designated the M121 BIX. The 55 PS OM621 diesel engine in the 200D was essentially identical to that of the 190Dc (which had already been 1988 c.c. despite the car being labelled as a '190') but was improved by using a five main bearing crankshaft instead of the original three. The 230 received a 2307 cc variant of the straight-6 M180 engine.

A detuned version of the 230S engine, it was given the carburetor system from the 2-liter M121 4-cylinder engine, and produced 105 PS.[5] From July 1966 on it received the unmodified 230S engine, raising output to 120 PS and improving both top speed and acceleration.[5]

Visually, the second series W110 models had the front indicators relocated from the top of the front fenders to below the headlights. At the rear, the tail lights were squared off and the chrome trim was revised to feature two horizontal trim strips instead of chrome-trimmed tail fins. All models gained air outlets with chrome trim on the C-pillars to match the W111 sedans. Inside, there were very few changes, with optional reclining backs on individual front seat models becoming standard. The 230 came with a central rear armrest.

Further changes occurred in late 1967 for the 1968 U.S. model year, including collapsible steering columns to meet new American safety regulations. Mirrors, interior door handles, and dashboard switchgear were also changed, matching those on the later W108/114/115 series cars.[6]

All three of the W110 second series cars ended production in January 1968 with the introduction of the W115 220 and 220D.
