All Japan Sports Prototype Championship
The Zen Nihon Sports Prototype Senshuken (Japanese全日本 スポーツ プロトタイプ 選手権, Eng. All Japan Sports Prototype Championship, abbreviated JSPC ) was held in Japan, national championship for prototypes of the Group C and IMSA GTP series. It was founded by the Nihon JIDOSHA Renmei (日本 自动 车 连 盟, Eng. Japan Automobile Federation, JAF ) and offered in their early years, vehicles after touring car regulations.
History
The race series began in 1983 under the name Zen Nihon Taikyu Senshuken (全 日本 耐久 选手 権, Eng. All Japan Endurance Championship ) as a long-distance championship, which was intended to replace the Japanese Touring Car Championship. To introduce the racing series four vehicle classes were represented, the A, B, C and D were called. The classes A and B were determined for touring cars, which were defined according to FIA regulations (Group A and Group B). The heart of the racing series were the classes C and D, in which vehicles from the Camel -Light class of the IMSA and Group C2 of the World Sports Car Championship ( WEC) or from the GTP class ( IMSA ) and the group C1 ( WEC) competed. In the first season three runs were in the racing calendar, one of which was part of the World Sportscar Championship. This meant that drivers who competed only in the national series were also scored in the World Cup.
In 1987, the touring car classes from the racing series were spun off, as they only competed in the championship now founded two years earlier for touring cars called All Japan Touring Car Championship. With this step, we wanted to define better the now Zen Nihon Sports Prototype Car Taikyu Senshuken (Japanese全日本 スポーツ プロトタイプ カー 耐久 選手権, Eng. All Japan Sports Prototype Car Endurance Championship ) called championship.
During its ten-year existence, the racing series gained notoriety by the competition between the various Porsche 956/962C and the Japanese manufacturers Toyota, Nissan and Mazda with its own works team. Because of the declining popularity of shooting in the air costs and the extinct group C and IMSA GTP class JAF sparked the series at the end of the 1992 season. As a substitute, the All Japan Grand Touring Car Championship ( JGTC ) was founded, in which it was the group C cars allowed to start for another two years before they were finally banned.
In 2006 there was again a Japanese racing series for sports car racing, the Japan Le Mans Challenge.
