Behold the Mercedez Benz C111. The experimental vehicle broke new ground, and set several speed records when it was first introduced in 1969 at the International Motor Show in Frankfurt. Set against the Hugh Stubbins-designed building, the car’s bold and expressive design successfully illustrates the German car manufacturer’s seasonal sartorial intentions. The colour, orange metallic, originally described as “rosé wine” was a trademark to the C111 concept car series. Less conspicuous, but no less unusual, were the technical innovations; The body consisted of fibre-glass reinforced plastic which was riveted and bonded to the steel frame-floor unit, and was the means by which mercedes tested their then-new Wankel engine. The Wankel engine, was a three-rotor unit, developing 206 kW (280 hp), which provided the propulsion power and permitted a top speed of 260 km/h – quite remarkable for its time. Little more was heard about the wankel engine as the advent of diesel technology rendered it obsolete. The C111, even today, continues to be a beautiful reminder of the timeless design and innovation of Mercedes Benz.
