If any single design concept is synonymous with the 1970s it must be The Wedge. Redolent of an imagined space-​​age future, the design was conceived at the end of the 1960s by epoch making designers like Giugiaro and Gandini. It wasn’t until the decade that moon shots came and went, however, that they saw the light of day, wrought in steel. Here are six of our favourite wedges.

The Dome Zero

Japanese company Dome released the Zero concept at the Geneva Motor Show in 1978, It was supposed to be a demon­stration of homolog­ation special for a new line of sports cars. However, it failed to pass homolog­ation regula­tions in Japan. In 1979 the company debuted a revised version of the car that came with U.S standard safety equipment. In the same year, a racing effort was launched at Le Mans but the ‘Zero RL’ failed to finish the race. Not the most successful wedge design, but it looked great anyhow.

The Lancia Stratos Zero

The Lancia Stratos Zero was a Bertone design exercise that was showcased at the Geneva show of 1970. The Zero was just 883mm high so drivers would have to lift the windscreen to mount the car. The Stratos HF production car was based on the concept – albeit very loosely.

The Maserati Boomerang

The Maserati Boomerang concept was presented at the 1972 Geneva Motor Show – sitting next to Giugiaro’s other famous wedge of that year, the Lotus Esprit M70. Its windscreen had an extreme 15 degree windshield rake. Giugiaro’s company ItalDesign appar­ently used the Boomerang as inspir­ation when designing the Delorean. In 2005 the original Boomerang concept was sold to a collector at a Christies’s auction for $1,000,000.

Pininfarina-​​Ferrari Modulo

Paulo Martin designed the rare and famous Pininfarina-​​Ferrari Modulo concept– and gained 22 design awards along the way. The extreme design was developed using the Ferrari 512-​​S racer, and was primarly a showcase for cutting edge build techniques – and of course to flex the flair and passion of Pininfarina to maximum degree.

Countach Concept

The original Countach concept was an unadul­terated, ground­breaking production design drawn by Gandini for Bertone in 1971. Its striking scissor doors were pilfered from the Alfa Carabo of 1968 – but were actually a practical requirement because of the extreme width of the car. The pure design of the concept was trans­lated loosely into the production first LP400. Soon however, splitters, wings and other safety equipment were added to the mix – watering down this most pure of seventies wedges.
