Mercedes-Benz W110

Mercedes-Benz W110

The W110 "Fintail" (German: Heckflosse) was Mercedes-Benz's line of midsize four-cylinder automobiles in the mid-1960s. The line was introduced with the 190c and 190Dc sedan in April, 1961,replacing the W120 180c/180Dc and W121 190b/190Db. The W110 line was refreshed in July, 1965 to become the 200 and Diesel 200D (model year 1966 for North America); at the same time, a six-cylinder 230 (successor to the Mercedes 220) became part of the W110 line. Production lasted just three more years, with the W115 220 and 220D introduced in 1968. The W110 and the 6 cylinder W111 were the first series of Mercedes cars to be extensively crash tested for occupant safety.

First Series (1961-1965)

The 190c and 190Dc replaced the W120 180c/180Dc  and W121 190b/190Db as Mercedes-Benz's line of less-expensive four-cylinder sedans. The "D" denoted a Diesel engine, a technology pioneered by Mercedes-Benz and championed despite widespread derision in the motoring press. The body was derived from the W111 series but with a 145mm shorter nose and rounded headlights (which gave a similar front-end appearance to the W120/121 ponton models). The rear end was identical to the W111 220b (the 220b was the base model of the W111 series). The interior layout and dimensions were also identical to the W111 220b, but with fewer options such as fixed-back seats and bakelite trim on the dashboard (as opposed to timber in the W111 models). Because the 190c and 190Dc models were basically a W111 220b with a shorter front, they offered the same interior and luggage space as the W111 series but with smaller and more fuel efficient engines. This made them extremely popular with taxi drivers.Production of the 190Dc exceeded that of the petrol engined 190c by nearly 100,000 units.

Second Series (1965-1968)

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 87mm 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. Visually, the second series models had the front indicators relocated from the top of the front fenders to below the headlights. At the rear, the tail lights were enlarged and squared off and the chrome trim was revised (including the removal of the chrome trim from the trailing edge of the tailfins). All models now featured air outlets with chrome trim on the C-pillars (identical to the W111 models). Inside, there were very few changes except all models now featured reclining front seats (previously an option on the 190c and 190Dc) and the 230 had a central armrest in the back seat as standard. In the later half of 1967 the interior door handles and dashboard switchgear were upgraded to match that of the W108/114/115 series cars.All three of the W110 second series cars ended production in January 1968 with the introduction of the W115 220 and 220D.
