Mercedes-Benz W107, its history

Summer 1971, in objective mathematical terms the solution is: W=C+R

The Mercedes W107 series consists of the automobile twins R 107 and C 107. The R 107 already has its premiere in March at the Autosalon in Geneva. Five months later, this roadster is standing in the sales rooms. The C 107 has its debut several months later in autumn in Paris. From January 1972 the first coupés are also standing in the dealers.

The R 107 combines all convertibles in this Mercedes-Benz series. The short wheelbase is their common feature. Its first name consists of a three-digit number combination. The surname consists of the abbreviation SL. Until now, nobody can say exactly what the definition of these two letters is. It shares this with its brother, the C 107, more about this later.

The design and other essential stylistic elements are the work of Friedrich Geiger. He has already collected plaudits at Mercedes-Benz. The connoisseur will find his signature in various series: W 198, W 100, W 111 / 112 (coupé version) ... There is a remarkable break in design in the models of the series R107. The current design vocabulary is clean and clear.

The sometimes expansive and opulent design is passé. Moderate use of chrome is trendy in these days. Broad-beam headlights, large fluted taillights and between them is a sober body with a subtle wedge-shape look. The icing on the cake is the subtle concave-shaped hard top. The style icon R107 is ready. Later, people talk about the notorious US-American stylistic excesses of this period.

Safety is the top priority for the
Mercedes R-107 engineers

Béla Barényi, an Austrian with Hungarian roots, is currently one of the leading designers at Mercedes-Benz. His pioneering developments also affect the nature of the W 107. The series W 111 to 113 also bear his signature. Passive security is realised in the form of the further developed three-box principle.

During the whole construction period, this is the invisible backbone of all R-107s. It possesses a striking, intelligently reinforced A-column. In the interior, this measure is supplemented by a foam-padded and a dashboard that yields on impact in the knee area, and the telescopic collapsible steering column. The new steering wheel is covered with polyurethane foam. From spring 1980, there is an anti-blocking system for the models of the series R 107. At the beginning of 1982 the range of equipment is completed by a driver’s airbag and a belt pre-tension system.

There are also interesting things to report
about the engines and gears

The drive assemblies predominantly have an engine block made of grey iron. In 1978, the 450 SL 5.0 is the first model to receive an aluminium cylinder block, followed by the 500 SL in the 1980s. In addition to this, it receives an automatic gearbox with four gears. In the production period, the R 107 is consistently further developed. It shows respect to the standards of the owners and markets in this period. Individual drives are modified on the basis of country-specific regulations. Variations in performance are the logical result.

Milestone IAA

In the construction phase of the Mercedes-Benz R107, there are milestones in 1980 and 1985. The site of these audience presentations is the IAA in Frankfurt. Engine displacements and outputs are optimised in the context of the facelift. The catalytic convertor finds its way into the range and the type 560 SL is exclusively launched for export.

The Mercedes-Benz R107 on the American market

The word export is a heading in itself. During this period, some stylistic elements emerge that irritate the sensibilities of many a European aesthete. These are the safety bumper bars demanded by the US-American market. They take up an enormous amount of space.

In the period from1971 to 1980, the following types of drive are offered: the 350 SL has a displacement of 3,499 cubic centimetres, a drive with eight cylinders and exactly 200 horsepower. The 450 SL also has eight cylinders and draws 225 HP from 4,520 ccm. Until March 1973, it is reserved for export to North America.

These two engines work as so-called intro models and are supplemented with the 280 SL from 1974. It has an engine with six cylinders and an output of 185 HP and from this point on forms the base drive. The changeover to a new injection pump (Bosch K-Jetronic) reduces the power output by five to seven HP in the period from 1975 to 1978.

In the time from 1980 to 1985, the 280 SL retains its customary place in the engine range. The outmoded eight-cylinders are replaced by the now contemporary versions 380 SL and 500 SL. 218 HP are obtained from 3,818. 4,973 cubic centimetres have a performance yield of 240 horsepower.

Redefinition of the Drive Range in 1985

After 1985, the following four engines redefine the drive range: again there is a variant with six cylinders. The displacement is equivalent to 2,962ccm. 188 HP are obtained. This is eight less with a catalytic convertor.

The eight-cylinder faction is formed by the 420 SL (4,196 ccm), 500 SL (4973 ccm) and the 560 SL (5,547, export only). They produce 218, 245 and 230 horsepower. With a catalytic convertor, their performances are 204, 223 and 230 HP.

In the eighteen years of its production period, 174,399 vehicle variants of the type R 107 are built.

The C 107 can also claim the above data (engines and gears). But exceptions confirm the rule:

This is the interpretation of a coupé for which the stubborn rascal Karl Wilfert is responsible. Unlike the roadsters, the C 107 possesses a 360 millimetres longer wheelbase. It is designed as a genuine four-seater. It has a rigidly installed roof and windows with built-in privacy screens for the rear seats. Its lifecycle starts in January 1972. Two aspects distinguish the automotive brothers. The 450 SLC 5.0, precisely the engine (4,939 ccm) that is not available for the roadster until 1980, already makes its debut in September 1977. It represents the top-of-the-range motorisation in the C107 from 1978 to 1980. This role is then taken over by the 500 SLC (4,939 ccm) by the end of production in 1981.

The SLC contributes 62,888 units to the total production figure of the W 107 (237.287 pieces). 174,399 units stand on the roadster’s lid.
