1998 saw a significant increase in manufacturer involvement. Porsche and Mercedes-Benz remained, with upgraded cars in both GT1 and LMP. Toyota sent three of their new, extremely fast GT-One racing cars, while BMW, in association with WilliamsF1, launched the new BMW V12 LM. Nissan sent 4 of their new R390 GT1s. The United States was also represented properly with a two car team from Panoz, with Ford powered Esperante GTR-1s.
Porsche won the race as the faster cars from Mercedes, BMW and Toyota retired with mechanical difficulties and accident damage. The remaining Nissans and outdated McLarens were unable to match the pace of the upgraded 911 GT1s. Following this race, Porsche went into a sabbatical, rumored to be part of a plan to allow Porsche's partner Audi to develop their own sportscar without competition from within the alliance.
Porsche would return to Le Mans in 2014; they would eventually win the 2015 race.
The GT2 class win by the Chrysler Viper GTS-R was the first GT class win for an American made car since the Shelby Daytona Coupe won in 1964.Pole Position - #35 AMG-Mercedes - 3:35.544
