Mercedes-Benz celebrates the 50th anniversary of the C 111 research and development iconic hypercar at Techno Classica 2019. Six original prototypes will be displayed at Mercedes exhibition stand, in Hall 1.
The first Mercedes C 111 was revealed at the Frankfurt Motor Show in September 1969. This high-performance sports car used the latest aerodynamic innovations, something that gave the model its distinctive wedge shape. The C 111 served to test the Wankel engine. A three-rotor unit developing 280 hp provided the propulsion power and permitted a top speed of 260 km/h, a rather impressive value at that time.
A few months later, Mercedes-Benz presented a heavily revised version of the C 111 at the 1970 Geneva Motor Show. This time, the concept featured a four-rotor Wankel engine with an maximum output of 350 hp. The car accelerated from standstill to 100 km/h in 4.8 seconds and reached a top speed of 300 km/h. This new four-rotor variant was more polished with a sophisticated design that appeared close to production ready. Speculation began that the C 111 would be a modern-day successor to the legendary 300 SL of the 1950s.
Ultimately, Mercedes-Benz never put these cars into series production, but instead made use of them as research and record cars. The 3-liter, five-cylinder engined C 111-II D, almost unchanged on the outside in comparison with 1970, was powered by a thoroughly revised five-cylinder diesel 3.0 litres engine with 190 hp. Developed to test a new exhaust gas turbocharger and a charge air cooler, this car ended up setting 16 world records in Italy, on the Nardo circuit, back in 1976.
A turbodiesel variant dubbed C 111-III was created, and in 1979 it set a new diesel record in April 1978 at 321.9 km/h over the 500-kilometre stretch. The following year a V8 petrol incarnation — C 111-IV — was created and a set circuit car record of 403.978 km/h – 250mph.
The two gullwing-door sports cars from 1966 and 1969 can be seen at the Techno Classica together with their successors.
