General Motors has been formally approved as a Formula 1 engine supplier for the 2029 season. The entry of GM's new team, which will race under its luxury Cadillac brand, was approved last month. Cadillac will make its debut as a team next year and will use Ferrari engines until GM's own engine is ready. The GM entry faced initial rejections but was eventually approved. F1 engine regulations for 2029 involve revised 1.6-litre turbo hybrid engines, with discussions ongoing for potential future changes.
