“Our new testing livery celebrates Detroit’s design heritage and the power of the global Cadillac Formula 1® team, while keeping our design secrets under wraps,” Reuss said. “The Barcelona test is just the beginning – we can’t wait to share our official race livery with fans around the world next month.” [Part of the marketing challenge Cadillac has is that it will use Ferrari F1 engines until GM Performance Power Units – founded by TWG Motorsports and General Motors builds powertrains for Cadillac Formula 1. This is likely to happen starting in 2029 if the engine is homologated by the FIA. – AutoCrat]

Distinctly different from the official race livery, the Cadillac Formula 1® Team Barcelona Shakedown livery was said to be a design created specifically for the demands of pre-season development. In Formula 1®, testing liveries traditionally help mask aerodynamic details ahead of competition, a variation of camouflaged prototypes in the automotive world. This one is claimed to express brand identity.

“Cadillac Formula 1® is committed to innovation on and off the track. TWG combined with General Motors allows us to rethink the norm and introduce the team in bold new ways. Debuting our race livery during a globally televised championship broadcast challenges convention and brings Cadillac Formula 1® to a global audience. Paired with this special-edition testing livery designed by the GM Global Design studios, we’re honoring automotive heritage while looking ahead as we build toward the 2026 season,” said Dan Towriss, CEO of Cadillac Formula 1® Team Holdings.
