The Mercedes-Benz W120 and W121 "Ponton" cars were produced from 1953 through 1962. They were sold under the "180" and "190" model names. The Ponton models were replaced by the W110 "Fintail" models beginning in 1961.
Mercedes also produced 6-cylinder Ponton models, the larger W128/W180 220s.

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 1962, replacing the W120 180c/180Dc and W121 190b/190Db. The W110 line was refreshed in 1965 to become the 230, with the lower 200 and Diesel 200D introduced in 1966. Production lasted just two more years, with the W115 220 and 220D introduced for 1968.
The 1962 190c 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 second series of 4-cylinder cars lasted just a few years. The six-cylinder 230 was introduced first, with the 200 and 200D coming for 1966. All three cars ended production in 1968 with the introduction of the W115 220 and 220D.
The Mercedes-Benz W114 (and similar W115) "Stroke-8" midsize cars were produced from 1968 through 1976. The W114 chassis used straight-6 engines and were sold under the "230", "250", and "280" model names. The W115 used straight-4 and straight-5 engines and were sold as the "200", "220", "230", and "240".
The Stroke-8 models replaced the W110 Fintail models beginning in 1968 and were replaced by the W123 series after 1976. The "stroke-8" name comes from the designation for the 1968 model year cars - they were informally called "W114/8" and "W115/8" the first year. This name stuck in common usage even after the "W114/9" was introduced in 1969. Today, "stroke-8" refers to the entire generation of cars.
Innovations in the stroke-8 models include a center console (a first in a Mercedes sedan), and a revised rear axle. All coupe models used the 6-cylinder engine (and thus were W114s) and were designated with a "C" in the model name.
