On the same day that Cadillac Hertz Team JOTA announced its drivers for the 2027 FIA World Endurance Championship, Cadillac Racing has also announced its drivers for the upcoming 2027 IMSA WeatherTech SportsCar Championship season.
At Cadillac Whelen (Action Express Racing), reigning GTP Champion Jack Aitken will defend his championship in the #31 Cadillac V-Series.R, one of two drivers running full-time in both IMSA and WEC, with no clashing race weekends between WEC and IMSA’s GTP class.
However, co-drivers Earl Bamber and Frederik Vesti have swapped roles: Vesti will now run full-time in the #31 Whelen Cadillac alongside Aitken, while Bamber will run select Michelin Endurance Cup races including the Rolex 24 At Daytona, where the team has finished second in two of the last three years.
“I’m thrilled to return to IMSA with Whelen Cadillac to defend our titles,” said Aitken. “We’ve built something pretty special over the last few years here and we know the competition will be just as fierce as ever, so I’m already looking forward to Daytona and a chance to pick up where we left off. Continuity on the driver lineup with Fred and Earl is great as we’ve got a fantastic chemistry between us, and seeing Fred step up to more racing this year will be fun as well.”
“Looking into 2027, I’m very motivated and very excited to be back with Action Express, but in a full-time capacity doing all nine rounds of IMSA,” said Vesti, who debuted with Action Express Racing as its Michelin Endurance Cup driver in 2025. “That’s always been part of the plan with the Whelen Cadillac team, a few learning years and then finally stepping up to fight for the championship, which I can’t wait.
“We are keeping consistency in the team, which means a lot to me. I think we are by far the strongest driver line up on the grid and I’m looking forward to continuing that journey. So yeah, thank you to (General Manager) Gary Nelson, the whole Action Express team, and of course, GM and Whelen Cadillac for the extension and very excited for the future.”
Bamber said, “I think what we’ve built over the last two seasons is something super special, and it just really thrills the team to get another IMSA championship, and also Jack his first IMSA championship. And now it’s all eyes forward to the big one for us, which is Daytona, where we’re trying to get Cadillac and Whelen their first win in the GTP era at Daytona.”
Cadillac Whelen will also enter a fourth driver for the Rolex 24 At Daytona, to be named later.
Meanwhile, Cadillac Wayne Taylor Racing continues with its two-car programme, and no change to its four full-time drivers.
Ricky Taylor and Filipe Albuquerque will return to drive the #10 WTR Cadillac, with Taylor also stepping into a dual-role as both an IMSA and WEC driver. Jordan Taylor and Louis Delétraz will pilot the #40 Cadillac. The team finally earned its first victory with the V-Series.R at Road America.
JOTA driver Will Stevens returns as the Michelin Endurance Cup driver of the #10 car, while his Cadillac Hertz Team JOTA teammate Norman Nato will replace Colton Herta as the endurance driver of the #40 car.
“Continuity is key and I’m excited to be returning in 2027 with the same driver lineup,” said WTR owner and namesake Wayne Taylor. “Delighted to welcome Norman Nato back in the #40 cockpit and will lean on the knowledge that he will bring to us from WEC. Given our win and double podium at Road America and additional podiums at Detroit and Petit, I feel confident that we have the right mix of drivers and am excited to go testing.”
Cadillac’s three teams combined for three victories, 11 podiums, and four pole positions last season in IMSA, en route to the 2026 GTP Manufacturers’ championship.
“We are proud to carry the momentum of our championship-winning 2026 season into 2027 with a driver lineup that combines proven IMSA experience, championship-caliber performance and the depth required to compete across the full GTP schedule,” said Eric Warren, Vice President, Global Motorsports Competition for General Motors.
“Our three Cadillac V-Series.R programmes have demonstrated remarkable consistency and pace, and this roster gives each team a strong platform for the 2027 season. The goal is clear: defend our titles, continue building on Cadillac’s endurance racing legacy and pursue success at every round, beginning with the Rolex 24 At Daytona.”
