IMSA - Frederik Vesti with Action Express Racing for Laguna Seca race

Action Express Racing confirmed that Vesti will sit in for Bamber for the IMSA race May 9-11 at Mazda Raceway Laguna Seca because of the overlap with the FIA World Endurance Championship race at Spa-Francorchamps in Belgium.

Bamber is doing double duty in 2025 with full season programs in the No. 31 Whelen Cadillac GTP entry and with Cadillac Hertz Team JOTA for the eight-race WEC campaign.

Vesti, the 2023 FIA Formula 2 Championship vice-champion and reserve driver for Mercedes-AMG Petronas Formula One team, will also contest the five endurance races in the No. 31 Whelen Cadillac V-Series.R.

Frederik Vesti, IMEC driver: “I can’t stop smiling to be honest. Being with Cadillac for the first time in Bahrain was a good experience but to finally start working with Action Express Racing and the whole Cadillac family in the U.S. is really cool. I’ve been looking forward for a few months now to get going with this program and now we’re finally here. These first few days have been really positive. I feel confident and comfortable in the car, which is not a given when you jump into a new car. From Lap 1, I’ve been really confident in this car. Therefore, I’m looking forward to the future.”
