Mercedes-Benz C111 Fornt_

In the 1960s and 1970s Mercedes was experimenting with new engine technologies, and used the C111 as common platform for the tests.

Other experimental features included multi-link rear suspension, gull-wing doors and a luxurious interior with leather trim and air conditioning.

The first version of the C111 was completed in 1969. The car used a fiberglass body shell and with a mid-mounted three-rotor direct fuel injected Wankel engine (code named M950F).

Frankfurt, September 1969: expectations were already running high. Rumours had been circulating for quite some time that Mercedes-Benz was planning to launch a sensation at the International Motor Show (IAA) in Frankfurt. But the car finally unveiled by the Stuttgart manufacturer surpassed even the wildest expectations. What the journalists got to see was a super sports car with gullwing doors and a Wankel rotary engine. It was a research vehicle that quickly became the absolute dream car of the 1970s.

The concept as a whole made the C 111 the absolute dream car of the seventies. Its engineering lived up to the promise of Bruno Sacco’s futuristic styling. Both the C111-I of 1969 with its three-rotor Wankel engine (206 kW/280 hp) and the C 111-II of 1970 with four-rotor Wankel engine (257 kW/350 hp) impressed with their effortlessly superior driving performance, delivering top speeds of 270 and 300 km/h respectively, while the C 111-II could accelerate from a standing start to 100 km/h in 4.8 seconds. Yet even when the Mercedes-Benz engineers pushed the Wankel engine to the very limits of its design, the result did not meet the high standards of Mercedes-Benz in terms of reliability and durability. The more stringent emissions legislation in the United States was to prove an added complication.

Its turbine-like characteristics and incredible output figures make this vehicle concept perfect. Mission accomplished.

But it was not only the disadvantages of the rotary piston engine that ultimately led to the decision not to proceed further with series production of the C 111. By the early 1970s, passive safety was becoming a more and more important factor in automotive development. The plastic bodyshell of the C 111 had an inherent disadvantage in this respect, compared with a conventional sheet steel body. And so it was that, in 1971, Mercedes-Benz made the decision not to move forward with series production of the sports car. The dismay among automobile enthusiasts was considerable. More than one such fan had taken a punt and submitted an order to the plant at Untertürkheim, along with a blank cheque – all to no avail.
