Mercedes Benz C111

The 60s and 70s lay claim to some of the maddest concept cars ever, with more angles between them than a GCSE maths textbook. But what these wheels lacked in style, they more than made up with sheer power..

MercedesBenz and its C111 managed to take a 230bhp diesel up to 200mph in 1978, while averaging 14.7mpg at just under that speed over 12 hours. Not concent with breaking multiple speed records, a 500bhp V8 variant hit 250mph in 1979.
