During the 1950s soon to be arch-rivals Ferrari and Porsche mostly competed in different classes but from the early 1960s the two legendary manufacturers gradually became direct competitors. One example was the European Hill Climb Championship for which both produced two-litre prototypes. Porsche had the upper hand in 1967 but the threat of an-all new flat-12 powered Ferrari, inspired the German manufacturer to push the envelop further than ever before. The result was the 909 Bergspyder, which tipped the scales at just 385 kg or 850 lbs. One example of the extremes the engineers went through, was the use of beryllium brakes; although very light, beryllium dust is toxic so the discs had to be chrome plated before they could be used. In order to ensure not a single steel nut, screw or washer was used, Porsche's motorsport supremo Ferdinand Piech supposedly went over the entire car with a magnet. The complete, and at times baffling history of the 909 Bergspyder can be found in our detailed article, which illustrated by an all-revealing 12-shot gallery of the example that is current on display in the Porsche Museum.
Porsche are again pushing the envelop with the 918 Spyder, which is scheduled to be launched in 2013. Built around a carbon fibre composite monocoque, the new supercar is powered by a hybrid drivetrain that consists of a competition derived, 570 bhp V8 engine and two electric motors. Following the release of pictures of a bare prototype, the German manufacturer have now published these pictures of a very thinly disguised test car. The 'camouflage' used is inspired by the 1970 Le Mans winning 917.
During this weekend's MINI United event at Paul Ricard, MINI revealed the limited edition John Cooper Works GP. Like the previous version, which was past on the first generation MINI Cooper, only 2,000 examples will be produced of what promises to be the fastest road-going MINI yet. No technical details have been revealed but according to MINI, the car is capable of lapping the Nurburgring in 8:23; a full 19 seconds faster than its predecessor.
