The Stratos was a very successful rally racing car during the 1970s and 1980s. It started a new era in rally racing as it was the first car designed from scratch for this kind of competition.
The bodyworks were designed by Bertone and were loosely based on a concept car first shown at the Turin Motor Show in 1971. The Stratos had a distinctive crescent-shaped wrap-around windshield providing maximum forward visibility with almost no rear visibility (which was unnecessary for rallying anyway). The body was wedge-shaped, and unusually short and wide, providing maximum traction.
The engine was a mid-mounted 190 bhp (140 kW) 2418 cc Dino Ferrari V6. For racing, this engine was tuned up to 280hp and even further with a turbocharger. However, turbocharged versions were only allowed to compete in Group 5 and were never as reliable as their naturally aspirated counterparts.
