The Lancia Stratos 0 (or Zero) pre-empted the Lancia Stratos HF prototype by 12 months and was first shown to the public at the Turin Motor Show in 1970. The futuristic bodywork was designed by Marcello Gandini, head designer at Bertone, and featured a 1.6 litre Lancia Fulvia V4 engine. The Lancia Stratos HF Zero stayed for a long time in Bertone's museum, and in 2011 was sold out during an auction in Italy for €761.600. The body was wedge-shaped, finished in distinctive orange and was an unusually short (3.58 m (141 in) length and only 84 cm (33 in) tall, and shared little with the production version. (wikipedia)
