Ferrari will deliver Cadillac's power units and gearboxes upon their arrival, but the team intends to produce their own engines by the end of the decade.
An 11th team on the F1 grid also opens up two extra seats, with team executive, Mario Andretti, revealing that they are looking for a young American and a veteran driver.
Outside of F1, Cadillac also have a presence in alternative motorsport series such as the World Endurance Championship.
The American outfit will enter their first season in the championship as Team Jota Cadillac this year, and have recently announced their lineup for the 2025 season.
2009 F1 champion, Jenson Button, will race for the team, alongside Earl Bamber and Sebastien Bourdais, with the trio of drivers competing in the #38 Cadillac V-Series.R LMDh.
Cadillac will also field a sister entry in 2025, and the #12 will be driven by Alex Lynn, Will Stevens and Norman Nato, whose first race will be the 10-hour Qatar 1812Km on February 28.
“Our job was to establish which combinations made the most sense to maximise the overall strengths of the group,” Jota team principal Dieter Gass said.
“While character and personality play a big role in team dynamics, driving style and preferences were also key factors in determining who would be paired in each car.
“We took our time over this process, and we’re really looking forward to seeing what both trios can achieve in Qatar and beyond."
