Reliability crisis in China: Carlos Sainz warns 2026 F1 engine rules are too complex. Carlos Sainz criticizes the 2026 F1 regulations after multiple cars failed to start the Chinese GP.

Sainz slams the new rules after China GP chaos

The 2026 Chinese Grand Prix opened a new front of discussion in Formula 1. Carlos Sainz called it “not a good image” that several cars were unable to start the race. Only 18 cars made it to the starting grid, as both McLarens, Gabriel Bortoleto’s Audi, and Alexander Albon’s Williams failed to take the start.

For Sainz, this incident is far from isolated. He sees it as a signal that challenges the credibility of both the FIA and Formula 1 itself, especially at a time when the championship aims to showcase itself as “spectacular.” At the heart of the debate are the new regulations governing the power units, which Sainz criticizes as overly complex and difficult to develop reliably.

What Sainz said

Speaking to media outlets including RacingNews365, Carlos Sainz didn’t mince words: “Certainly, it’s not a good image for anyone. I think the absence of both McLarens, the Williams, and the Audi on the grid shows how much we complicate our lives by creating engines with extremely complex software and battery management.”

On the topic of the 2026 F1 power units, the Spanish driver was clear: “It’s up to the teams to develop the engines, but when the rules are so demanding and restrictive, it’s very difficult to achieve something reliable, because it’s extremely complex for everyone.”

Hopes for improvement

Despite the difficulties and various complexities, Carlos Sainz remains open to technical progress. “Today’s F1 is definitely far from ideal. But I hope that development and fine-tuning of the regulations will improve things in the future.”

The technical nightmare witnessed in Shanghai therefore shows that innovation should not come at the cost of basic participation. While the 2026 era promises sustainability and close racing, the current reliability crisis suggests that the “over-complicated” nature of the power units remains a significant barrier for the manufacturers. Based on the content of the post-race analysis in China, the FIA may face increasing pressure to simplify these systems before the reliability woes become a permanent fixture of the season.
