Valtteri Bottas in the Cadillac ahead of Audi's Gabriel Bortoleto during pre-season testing in Bahrain

There are two new Formula 1 teams in 2026, representing two of the world's biggest car companies. They have the same ambition, but they are two very different projects.

Audi has taken over the Sauber team to form the basis for its works assault on F1, marking parent company the Volkswagen Group's first foray into the highest level of the sport.

US giant General Motors (GM) is also trying out F1 for the first time. It has joined forces with US sports conglomerate TWG to form a new team named after its luxury Cadillac brand.

Both were tempted in by the engine rules introduced this year, believing the increased effect of the hybrid part of the engine was an important marketing point for their road-car portfolios.
