As usual, model names were related to engine sizes, type of engine and chassis type:
- C for Coupé
- Lang (long-wheelbase)
- T for Transport and Touring (estate/station wagon)
- D for Diesel,
- E for Einspritzung (fuel injection)
Model history
Mercedes-Benz introduced the W123 four-door versions in January, 1976. While there were some technical similarities to their predecessors, the new models were larger in wheelbase and exterior dimensions. The styling was also updated, although stylistic links with the W115 were maintained. Initially, all models except 280/280E featured quad unequal-size round headlights and the latter large rectangular units. When facelifted these units became standard across the range. All W115 engines were carried over, with the 3 litre

version was introduced on a shorter wheelbase than the saloon (2710 mm (106.7 in) versus 2795 mm (110 in)) for the saloon. This W123C/CE was available as a 230C (later 230CE) and as a 280C/CE in most markets; in North America there were additional 300CD versions with naturally aspirated, later turbocharged 3 litre diesel engines.
It is a tribute to the car's instant popularity – and possibly to the caution built into the production schedules – that nine months after its introduction, a black market had developed in Germany for Mercedes-Benz W123s available for immediate delivery. Customers willing to order new cars from their local authorized dealer for the recommended list price faced waiting times in excess of twelve months. Models that were barely used and were available almost immediately commanded a premium over the new price of around DM 5,000.
From August, 1977, long-wheelbase versions (3425 mm (134.8 in)) were produced. These were available as 7/8 seater saloons with works bodies or as a chassis with complete front body clip, the latter serving as the base for

At the Frankfurt Auto Show in September, 1977 the W123T estate was introduced; the T in the model designation stood for "Touring and Transport". All engines derivative except "200TD" were available in the range. T production began in March, 1978 in Mercedes'

factory.
In early 1979, the diesel models power output was increased; power rose from 55 PS to 60 PS in the 200D, from 65 PS to 72 PS in the 240D and from 80 PS to 88 PS in the 300D; at the same time, the 220D went out of production.
The first Mercedes turbo diesel production W123 appeared in September, 1979. This was the 300 TD Turbodiesel, available with automatic transmission only. In most markets, the turbocharged 5-cylinder 3 litre diesel engine (Type OM617) was offered only in the T body style, while in North America it was also available in saloon and coupé guises.

petrol engines (Type M102). A new 2 litre four with shorter stroke replaced the old M115, a fuel-injected 2.3 litre version of this engine (in 230E/TE/CE) the old carbureted 230. Both engines were more powerful than their predecessors.
In 1980/81 the carbureted 280 versions went out of production; the fuel-injected 280E continued to be offered.
In September, 1982, all models received a mild facelift. The rectangular headlights, previously fitted only to the 280/280E, were standardized across the board, as was power steering. Since February, 1982, an optional 5-speed manual transmission was available in all models (except 300 TD).
W123 production ended in January, 1986 with 63 T-models rolling out.
Most popular single models were the 240D (455,000 built), the 230E (442,000 built) and the 200D (378,000 built).
W123 introduced innovations including

Power (vacuum servo) assisted disc brakes were standard on all W123s.
