On Saturday, the North American sports car season draws to a close with the Petit Le Mans. A 10-hour race held at Road Atlanta in Georgia, this year’s Petit Le Mans is also the last race for a fan-favorite class of cars. Known as GTLM, this category was for Le Mans-legal versions of two-door production cars, over the years a playground for manufacturer-supported programs and some of the world’s best racing drivers.
On the one hand, it’s a massive step for the US side of endurance racing—the end of one direct link that the Weathertech Sportscar Championship has with annual 24 Hours of Le Mans. But it also reduces some needless complication for the sport.
“Even for some of the most avid car people, they have a hard time understanding why the red BMW is so much faster than the yellow and blue one; or the red, white, and blue Porsche is so much faster than the #9 car or the #16 or the #88,” said John Doonan, president of the International Motor Sports Association (IMSA), the sport’s organizer.
