- Action Express Racing announced Thursday morning that Tom Blomqvist will serve as the team's third driver for the IMSA Michelin Endurance Cup races in 2024. Blomqvist is moving full-time to the NTT IndyCar Series in 2024 with Meyer Shank Racing with Curb-Agajanian, but will keep his foot in IMSA going forward. Blomqvist will technically replace Jack Aitken in the role. Aitken is now full-time with Action Express while Pipo Derani's teammate in 2023, Alexander Sims, is moving to the factory-supported
Corvette Racing by Pratt Miller Motorsports in the GTD Pro class.
