Mercedes-Benz C 111-II experimental vehicle (1970)

Mercedes-Benz Classic is entering two legendary sports cars in the Schloss Bensberg Supersports Classics (SBSC): the Mercedes-Benz 300 SL Roadster (W 198) celebrated its premiere in 1957, whilst the experimental vehicle C 111 dates back to 1970. As part of the rally for classic sports cars and young classics up to 1997 the SBSC will also be presenting current super sports cars this year.
Mercedes-AMG, the Mercedes-Benz performance brand founded 50 ago as an engineering office, is present here with two models from the Mercedes-AMG GT model series family (fuel consumption combined: 11.4 -9.3 l/100 km CO2 emissions, combined 259-216 g/km*).

This year the Schloss Bensberg Supersports Classics (SBSC) rally is offering lively dialogue between historic and modern super sports models. For both at the classic rally through the Bergisches Land region on Saturday, 1 July 2017 and at the Concours d’Elégance on 2 July current super sports cars are joining the impressive parade of classic cars and young classics.

Mercedes-Benz Classic and Mercedes-AMG are offering two special couplings which illustrate the tradition of sportiness in the brand´s genes: unveiled in 1957, the classic 300 SL Roadster (W 198) is as coveted today as the Mercedes-AMG GT C Roadster which premiered in spring 2017 (fuel consumption combined: 11.4 l/100 km, CO2emissions combined: 259 g/km). And the visionary power injected into the Mercedes-Benz C 111 II experimental vehicle in 1970 also characterised the Mercedes-AMG GT R in 2016 (fuel consumption combined: 11.4 l/100 km, CO2 emissions combined: 259 g/km).

The vehicles are driven and presented by personalities such as the racing drivers and Mercedes-Benz Brand Ambassadors Klaus Ludwig and Jan Seyffarth.

Princely stage for super sports models

Founded in 2009, the Schloss Bensberg Supersport Classics is being held around the Baroque hunting lodge in the Bensberg area of the town of Bergisch Gladbach.

On the Saturday (1 July) the rally starts at 9 a.m. In total around 260 kilometres are covered in the Bergisches Land in this challenging regularity race. Along the route the participants can expect five checkpoint controls with presentations of the vehicles to the public in Wermelskirchen, Lindlar, Ehreshoven, Bergisch Gladbach and Blankenberg. There are also twelve allocated time stages on the rally schedule. The vehicles are expected back in the palace courtyard at around 4.30 p.m.. The modern super sports cars head the rally in front of the peleton of classic cars and young classics. Entry to all the day´s activities is free.

On the Sunday (2 July) all the vehicles participating in the rally will be presented at the Concours d’Elégance. A special presentation is devoted to the current super sports cars.

Mercedes-Benz 300 SL Roadster (W 198, 1957-1963)

At the Geneva Motor Show In March 1957 Mercedes-Benz unveiled the 300 SL Roadster (W 198) as the successor to the 300 SL (W 198) “Gullwing” Coupé unveiled in 1954. On a technical level, the open-top sports car was very like the Coupé, although the modified space frame allowed the installation of conventionally attached doors, which were necessary for open-top driving. The suspension was likewise modified: the single-joint swing axle with lowered pivot point on the 300 SL Roadster was equipped with a compensating spring for the first time. From 1958 onwards the roadster was also available with a detachable coupé roof on request. It was from the standard-production 300 SL Roadster that the Mercedes-Benz engineers developed the 300 SLS racing variant with which Paul O’Shea won Category D of the American Sports Car Championship in 1957. So we´ve come full circle, as the model series 198 of the 300 SL is based on the W 194 racing car of the same name which was used very successfully in motorsport in 1952. Production of the 300 SL Roadster was discontinued in 1963 after seven years, during which time only 1858 units of the highly exclusive sports car were built.

Mercedes-Benz C 111-II experimental vehicle (1970)

Mercedes-Benz presented the C 111 at the Frankfurt Motor Show (IAA) in September 1969. With its extreme wedge shape and gullwing doors, the research vehicle had a glass-fibre-reinforced plastic body and was powered by a three-rotor Wankel engine with an output of 206 kW (280 hp). This futuristic sports car could reach a speed of up to 270 km/h. The following year, the revised C 111-II version was shown at the Geneva Motor Show – except now with a four-rotor Wankel engine delivering 257 kW (350 hp). This version could accelerate from 0 to 100 km/h in 4.9 seconds and reach a top speed of 300 km/h. It was this second version of the research vehicle that served as the basis for a V8 variant of the C 111 containing the M 116 production engine with 147 kW (200 hp). Mercedes-Benz engineers and technicians used the car for the purposes of comparison with the rotary-engined sports car. Despite numerous orders, the C 111 remained a purely experimental vehicle and never entered production. Mercedes-Benz instead went on to develop a series of record-breaking vehicles based upon it: the C 111-II D (1976) and the C 111-III (1977–1978, both with a five-cylinder turbodiesel engine) and the C 111-IV (1979, V8 petrol engine with turbocharging).
