Cadillac’s Formula One effort has taken another step forward with the FIA approving their power unit for use in 2029.

US car company General Motors has been formally approved as a Formula 1 engine supplier for the 2029 season. The development, announced jointly by governing body the FIA and General Motors, is the first time a specific year has been put on the debut of GM's engine.

The target is a year later than initially planned, so Cadillac F1 will run with Ferrari engines for three years, rather than two.
