History of the Mercedes-Benz W114/W115

The W114 and W115 were marketed as New Generation models, the only Mercedes-Benz cars to receive that designation, and the /8 on their identification plates, marking the 1968 launch, gave them the nicknames /8 or stroke eight. They were the first post-war Mercedes-Benz production cars to use the new semi-trailing rear arm and ball-joint front suspension, a layout used in all new passenger models until the multi-link rear suspensions of the 1980s. The first S-Class, the W116, used the same engineering on a larger platform.

The cars were distinguished by nameplates relating to engine size: the W114 had six-cylinder engines and was sold as the 230.6, 250 and 280, while the W115 had four-cylinder engines and was sold as the 200, 220, 230.4 and 240, with diesel versions carrying a D. The W114/W115 was also where Mercedes-Benz launched its first five-cylinder diesel, the OM617. A coupé joined in 1969 with a longer boot lid and a choice of 2.5 or 2.8-litre six, its pillarless design allowing all the windows to be lowered; 67,048 coupés were built against 1,852,008 saloons, 24,669 of them 280 C and 280 CE and 42,379 the 250 C and 250 CE.

In 1968 the W114/W115 was the first Mercedes-Benz to receive the fully electronic Bosch D-Jetronic fuel injection, first in the 250 CE and later the 280 CE. In August 1973 the range was facelifted with a lower bonnet line, a lower and broader grille, a single front bumper replacing the double bumpers, lower headlamps, new A-pillar treatment to keep the side windows clear, ribbed tail lights and larger mirrors, while the interior gained inertia-reel seatbelts and a padded four-spoke steering wheel. The W115 is remembered for its durability: in 2004 the Greek taxi driver Gregorios Sachinidis gave his 1976 240 D to the Mercedes-Benz museum with 4.6 million kilometres on the odometer, the highest recorded mileage of any Mercedes-Benz.
