context_page_description: The World Sportscar Championship was the world series run for sports car racing by the FIA from 1953 to 1992.
  The championship evolved from a small collection of the most important sportscar, endurance, and road racing events in Europe and North America with dozens of gentleman drivers at the grid, to a professional racing series where the world's largest automakers spent millions of dollars per year. The official name of the series changed throughout the years, however it has generally been known as the World Sportscar Championship from its inception in 1953. The World Sportscar Championship was, with the Formula One World Championship, one of the two major world championships in circuit motor racing.
  In 2012 the World Sportscar Championship was revived and renamed as the World Endurance Championship.
context_section_description: In 1982, the FIA attempted to counter a worrying climb in engine output of the Group 5 Special Production Cars by introducing Group C, a new category for closed sports-prototypes (purpose built racing cars) that limited fuel consumption (the theory being that by limiting fuel consumption, engine regulations could be more relaxed).  While this change was unwelcome amongst some of the private teams, manufacturer support for the new regulations was immense. Several of the 'old guard' manufacturers returned to the WSC within the next two years, with each marque adding to the diversity of the series.  Under the new rules, it was theoretically possible for normally aspirated engines to compete with the (expensive to maintain) forced induction engines that had dominated the series in the '70s and early '80s. In addition, most races ran for either 500 or 1000 km, usually going over three and six hours, respectively, so it was possible to emphasize the "endurance" aspect of the competition as well. Group B cars, which was a GT class, were also allowed to race, but entries in this class were sparse, and Group B cars disappeared from the series, with sports-prototypes dominating the championship.
  Porsche was the first constructor to join the series, with the 956, but soon several other makes joined the series, including Jaguar Cars, Mercedes-Benz, Nissan, Toyota, Mazda and Aston Martin.  As costs increased, a C2 class (originally named C Junior) was created for privateer teams and small manufacturers, with greater limits to fuel consumption. In this lower class, most cars used either the BMW M1 engine or the new Cosworth DFL, but, like in the main class, a variety of solutions were employed by each individual manufacturer. Alba, Tiga, Spice and Ecurie Ecosse were among the most competitive in this class.  While the Group C formula had brought manufacturers back to the sport, it was again Porsche - with its 956 & 962 Group C line - that continued their domination of the sport.
  For 1986, the World Endurance Championship became the World Sports-Prototype Championship.
  Although the Group C formula was a success, with regular crowds of 50,000 to 70,000 at WSC events (a modern Grand Prix in Europe will have similar crowds), and upwards of 350,000 at the 24 hours of Le Mans, the FIA introduced new rules for 1991 at the behest of FIA vice president Bernie Ecclestone; 750 kg machines with contemporary normally aspirated engines, which were purpose-built 3500cc racing units.  The new classification, known as Group C Category 1, was designed to mandate Formula One engines. Although power was generally less than existing Group C cars (around 650 bhp compared to around 750 bhp upwards) the new cars are considered to be among the quickest sportscars ever. However, the take up of these new regulations was slow and only a handful of Category 1 cars were ready for the 1991 season. Consequently, the FIA also allowed cars complying with pre-1991 Group C rules to contest the championship (as Group C Category 2 cars) during the one transitional year. They were however seriously handicapped in terms of weight, fuel allocation and grid positions. For 1991 the championship took on yet another new name, the FIA Sportscar World Championship and the new 3.5 litre rules took full effect for the 1992 championship with the old Group C cars no longer included.
