IMSA, the Automobile Club de l'Ouest (ACO) phased out its LM P1 category, instead drawing up regulations based closely on IMSA's World Sportscar (WSC) class. In return, IMSA agreed to allow turbo-engined cars into WSC, given the number of Group C chassis still in circulation. The LM P2 class was left as is; however, the other classes had the following restrictions, some revised from the previous year: WSC max 4.0L or 3.0L (turbo), with rev limit of 8500 rpm (2-valve V8) or 10500 rpm (4-valve V12), fuel tank 80L, min weight according to engine size and type, max tyre width 18" LM P2: fuel tank 80L, min weight 620 kg, with production engines, max tyre width 12" LM GT1: fuel tank 100L, min weight 900 kg, max tyre width 14" LM GT2: fuel tank 100L, min weight 900 kg, max tyre width 12" The previous year's "one-off model" rule, controversially exploited by Porsche in the 1994 race, stayed in place for GT1. However, GT2 cars had to be based on cars in series production since February 1995. As before, these regulations generated a huge amount of interest, and the ACO received 99 entries. In response, the ACO built 2 further pit bays to increase capacity to 50 cars. They granted 20 well-performing teams an automatic entry, then chose a further 50 to go through qualification for the remaining 30 spots on the grid. It aimed to keep a balance between the WSC and over-represented GT classes, although the lines were now blurring a bit in GT1. Sportscar specialists Courage, Kremer, WR and Debora returned in WSC/P2, along with the first Ferrari prototype (the 333SP) seen at Le Mans for 23 years, which had been running in the American IMSA championship. Commissioned off Ferrari for the WSC by Giampiero Moretti of Momo Racing The Japanese returned in force in the GT1 class with Toyota, Nissan, Mazda and Honda all sending works, or works-supported, teams. But the biggest splash came from McLaren: its new F1 GTR supercar had won 6 of the 7 races in the 1995 BPR Global GT series to date. Six of the McLarens from that series arrived, and even the original T-car was hastily prepared for a new Japanese team desperate to be involved. The McLaren was the fastest road car in the world and a natural choice for Le Mans; Gordon Murray's carbon-fibre design conforming to the
