Sergio Perez warns Formula 1's 2026 cars create dangerous speed differences that could cause serious accidents.

Sergio Perez expressed fears that Formula 1's new power units with 47% electrical energy create dangerous speed differentials between cars depending on energy deployment. The Cadillac driver revealed he nearly had a massive crash with Liam Lawson in Baku when defending position due to the extreme power differences.

The speed variations stem from Formula 1's new 2026 engine regulations, which create substantial contrasts between cars based on their energy deployment strategies. This was a major concern early in the season, particularly after Oliver Bearman's major crash in the Japanese Grand Prix when he encountered a slower Franco Colapinto while taking avoiding action.

The FIA implemented rule changes during the April break to reduce lift-and-coast tactics, but Perez believes the fundamental problem remains unresolved. He specifically noted that Mercedes and Red Bull have stronger engines that can deploy power in places where other teams show poor performance, creating speed differences that are too dangerous for racing.
