Mercedes-Benz W123
A broad and durable model family that became one of Mercedes-Benz's greatest production successes.
Overview
Mercedes-Benz presented the 123-series saloon in January 1976 as the successor to the W114 and W115 models. The initial range was unusually broad, with nine petrol and diesel versions spanning the 200 D to the fuel-injected 280 E.
The new model combined conservative styling with substantial engineering development. Its double-wishbone front suspension used zero steering offset, while passive-safety measures included a collapsible steering column and a fuel tank protected above the rear axle. Anti-lock brakes became optional in 1980, followed by a driver’s airbag in 1982.
Four body families gave the 123 series a reach beyond the conventional saloon. Mercedes-Benz added a lower, shorter coupé, a long-wheelbase saloon with seven or eight seats, and its first estate designed and built in-house. Approximately 2.7 million vehicles were produced across the range.
Body families
Saloon and long wheelbase (W123 and V123, 1976–1985)
The four-door saloon formed the core of the range and accounted for nearly 2.4 million cars. A lengthened version served customers needing additional seating, including taxi and chauffeur operators.
Coupé (C123, 1977–1985)
The pillarless coupé had a wheelbase 85 millimetres shorter than the saloon’s and a roof 40 millimetres lower, giving it distinct proportions while retaining the main model’s engineering.
T-Model estate (S123, 1978–1986)
Unveiled in 1977 and placed into series production in 1978, the T-Model established the factory-built Mercedes-Benz estate as a permanent model type. Its designation referred to tourism and transport, and self-levelling rear suspension was standard. The 300 TD Turbodiesel introduced turbocharged diesel power to a German passenger car in 1980.
