The Lancia Stratos HF (Tipo 829), widely and more simply known as Lancia Stratos, is a sports car and rally car made by Italian car manufacturer Lancia. The HF stands for High Fidelity. It was a very successful rally car, winning the World Rally Championship in 1974, 1975 and 1976.
The Stratos was a successful rally car during the 1970s and early 1980s. It started a new era in rallying as it was the first car designed from scratch for this kind of competition. The three leading men behind the entire rallying project were Lancia team manager Cesare Fiorio, British racer/engineer Mike Parkes and factory rally driver Sandro Munari, with Bertone's Designer Marcello Gandini taking a personal interest in designing and producing the bodywork.
