As it turned out, the 1995 Le Mans was a wet one. Yannick Dalmas, Masanori Sekiya, and JJ Lehto (the drivers of the winning car) soon realized that they were 35 seconds per lap faster in the wet than even the fastest prototypes, and they capitalized on that. Once the rain dried up, there wasn’t enough time left for the prototypes to make up the difference.
McLaren entered seven GTRs that year. Two failed to finish, one obviously won outright, and the rest placed 3rd, 4th, 5th, and 13th. McLaren claimed first and second in their class in the 1997-spec cars, but the GTR never won an overall event again. In fact, 1995 was a one-hit wonder. McLaren had never won it before and has yet to win it again. However, it was the most successful debut of any team at Le Mans.
There isn’t a single McLaren entered in this year’s Le Mans, though the name is still active in IndyCar.
