Drivers from the NTT INDYCAR SERIES and INDY NXT by Firestone are extending their racing seasons by competing in all four classes of Motul Petit Le Mans, the season-ending IMSA WeatherTech SportsCar Championship race Oct. 1-3 at Road Atlanta.

INDYCAR SERIES champions Scott Dixon and Alex Palou will be teammates – perhaps for the last time after their six seasons together at Chip Ganassi Racing – in the premier Grand Touring Prototype (GTP) class in the 10-hour race Saturday, sharing separate entries for Acura Meyer Shank Racing w/Curb Agajanian.

Six-time series champion Dixon will share the No. 60 Acura ARX-06 with former INDYCAR SERIES drivers Tom Blomqvist and Colin Braun on the 12-turn, 2.54-mile road course in Braselton, Georgia. Dixon is leaving Chip Ganassi Racing at the end of this year after 24 full-time seasons to join Arrow McLaren next season in the NTT INDYCAR SERIES.

Five-time series champion Palou will start two consecutive weekends of sports car racing by sharing the No. 93 Acura ARX-06 (photo, top; courtesy IMSA Photo) with Nick Yelloly and Renger van der Zande. Palou also is driving in the Indianapolis 8 Hour Intercontinental GT Challenge race Oct. 10 on the Indianapolis Motor Speedway road course.

Palou and Dixon have a good chance at overall victory Saturday if speed in the opening practice Thursday is any indication. Yelloly was quickest at 1 minute, 11.506 seconds in the No. 93, while Braun was a whisker slower at 1:11.509 in the No. 60.

Not only is this event an end to Dixon and Palou as teammates, but it also marks the end of Acura’s prototype program in IMSA and with MSR.

In another note of interest in the GTP class, former INDYCAR SERIES driver Colton Herta is returning to America to share the No. 40 Cadillac Wayne Taylor Racing Cadillac V-Series.R with Jordan Taylor and Louis Deletraz. Herta had a disappointing first season in 2026 in Formula 2, the final step on the ladder to Formula One.

The GT Daytona PRO (GTD PRO) class features two INDY NXT by Firestone champions among its driver lineups.

2021 INDY NXT champion and 2026 NTT INDYCAR SERIES runner-up Kyle Kirkwood will return to the No. 14 Vasser Sullivan Racing Lexus RC F GT3 as a teammate to former INDYCAR SERIES and INDY NXT driver Jack Hawksworth and Ben Barnicoat. Kirkwood was quickest in the class in practice Thursday.

Freshly crowned INDY NXT champion Nikita Johnson will race in the No. 59 RLL Team McLaren McLaren 720S EVO GT3 (photo, above) that he also drove in the TireRack.com Battle on the Bricks on Sept. 20 at IMS.

The Le Mans Prototype 2 (LMP2) and GT Daytona (GTD) classes each feature one active INDY NXT by Firestone driver.

Jacob Abel is sharing the No. 18 Era Motorsport LMP2 car, while James Roe is in the driver lineup for the No. 80 Lone Star Racing Mercedes-AMG GT3 in GTD.

Live coverage of the 10-hour race begins from noon-3 p.m. ET Saturday on NBC, followed by 3-10:30 p.m. ET on NBCSN. The entire race also will be streamed on Peacock.
