GM's Big Weekend: Larson Repeats in NASCAR as Corvette Wins a WEC Title
Kyle Larson won a third Cup title, Chevrolet set an O'Reilly Series record, and TF Sport's Corvette took WEC's LMGT3 crown, all in two days.
General Motors won five championships in two days to close out the 2026 racing season. The biggest came on Sunday, when Kyle Larson clinched the NASCAR Cup Series crown in his No. 5 Hendrick Motorsports Chevrolet at Homestead-Miami Speedway, hours after a Corvette sealed the LMGT3 titles in the FIA World Endurance Championship at Monza.
It was the same weekend Toyota celebrated its 700th NASCAR win and a Truck Series title. But the Cup championship, NASCAR's top prize, stayed with Chevrolet.
A record year in NASCAR's second tier
The title in NASCAR's second-tier O'Reilly Auto Parts Series was settled long before Saturday's race in Miami. Chevrolet drivers won 29 of the season's 33 races, which GM calls the brand's best year in the series. That delivered Chevrolet its 10th consecutive manufacturer championship and its 20th this century.
The only open question was which Chevy driver would take the driver title. Justin Allgaier settled it by finishing seventh in the No. 7 JR Motorsports Chevrolet, his second championship in the series.
Larson needed only a quiet afternoon on Sunday. He arrived with a 67-point lead over Joe Gibbs Racing's Toyota drivers, Christopher Bell and Denny Hamlin, and finished 12th. It's his third Cup title after 2021 and 2025, and according to NASCAR, he's the first driver to win back-to-back titles since Jimmie Johnson in 2010. GM admits the season started badly for its Cup teams, who spent the early races learning an updated Camaro ZL1.
Corvette and Cadillac at Monza
In Italy, TF Sport's No. 33 Corvette Z06 GT3.R finished third at the WEC finale, enough to win the LMGT3 teams' trophy and the drivers' title for Jonny Edgar. Aston Martin's Vantage came within a fraction of a second of winning the class. This is Corvette's second WEC title and the British team's first since switching to the Corvette in 2024. The car's season also included a class win at Le Mans, Corvette's 10th there.
The same race went to Cadillac outright. Sébastien Bourdais, Earl Bamber, and Jack Aitken won in Hertz Team JOTA's No. 38 V-Series.R, weeks after Cadillac took all three IMSA GTP titles.
Why GM keeps paying for it
GM's motorsports chief, Eric Warren, argues that racing works as a test bed whose lessons can inform the company's production vehicles. The Corvette makes that case most clearly: the GT3.R shares its name and basic shape with the road car sold in the 2027 Corvette lineup.
NASCAR's competition is about to grow. Dodge returns to the Cup Series in 2027, turning the Cup Series into a four-way fight among Chevrolet, Ford, Toyota, and Dodge. For now, the trophies sit in Detroit. You can read the full results in GM's own recap.
