In the spring of 1976, a coupe version of the W123 was introduced on a shorter wheelbase
than the saloon (2,710 mm (106.7 in) versus 2,795 mm (110.0 in)). This W123C/CE was
available as a 230C (later 230CE) and as a 280C/CE in most markets; in North America
there was also a 300CD version.
The new models proved to be the most popular series to date. Demand for the W123 was
so great, back orders and waiting lists of over a year were common and used cars sold at a
premium over the new car list price.
A long wheel base chassis (3,425 mm (134.8 in)) was introduced in August, 1977. The long
chassis versions were available as 7/8 seat saloons through the factory and as a bare
chassis with front body clip for ambulances, hearse bodies etc. Outside manufactures such
as Binz or Miesen produced a variety of models on these long chassis. The long (Lang)
versions could be ordered as 240D, 300D and 250 models.

In early 1979, the diesel models power output was increased from 55 PS (40 kW; 54 hp) to
60 PS (44 kW; 59 hp) in the 200D, from 65 PS (48 kW; 64 hp) to 72 PS (53 kW; 71 hp) in
the 240D and from 80 PS (59 kW; 79 hp) to 88 PS (65 kW; 87 hp) in the 300D.
Production of the 220D ended in early 1979.
The turbo charged 5 cylinder engine was introduced in September 1979 in the 300TD
Turbo diesel wagon. The turbocharged 5-cylinder 3 liter diesel engine (Type OM617) was
offered with automatic transmission only and limited to the 300TD in most markets. The
North American markets were given Turbo models in the 4-door and coupe models as well,
possibly as a response to the competition from higher powered American cars.
In June of 1980 a new 2 liter 4-cylinder gasoline engine (Type M102) was introduced to
replace the M115. A fuel-injected 2.3 liter version was introduced to replace the carbureted
engine in the 230E/TE/CE models. In 1980/81 the carbureted 280 was replaced with the
In September 1982 the rectangular headlights from the 280/280E and power steering
were standardized across all European models. In February all European models except the
300TD were offered with an optional 5-speed manual transmission.

(optional from August, 1980), retractable steering columns and airbags for the driver
(optional from 1982).
