Wolff has no concern for 'good as gold' Mercedes engines after recent failures plague teams

In the turbo-hybrid era, Mercedes has been widely regarded as the best engine manufacturer since the 2014 debut of the 1.6-litre V6. The German marque has struck a balance between performance and almost bulletproof reliability in the last few years. However, recent failures have led some to question whether Mercedes is facing end-of-the-road problems as the focus shifts firmly to the 2026 regulations. 

In 2025, Mercedes' HPP (High Performance Powertrains) engine is also used by Williams, McLaren and Aston Martin.

Championship leaders McLaren are the only team yet to have suffered an engine failure. During the last triple header, Aston Martin's Fernando Alonso suffered an engine failure in Monaco, with home hero Kimi Antonelli forced to retire his Mercedes from the race in Imola. Last weekend, Alex Albon's Williams failed to finish after he pulled off the circuit in the final sector due to engine issues.

Speaking after the race, which Mercedes driver George Russell won, Wolff defended Mercedes' power units, which have been stalwarts of reliability in recent times. "I mean, our engines have been as good as gold since the introduction of the hybrid era, and so strong. And now it's the final year, all sights are on next year, and this group are fully on top of the reliability issues that we have," Wolff explained.

"And statistically, if you look at the many years, the failures we had were very minimal. So we need to learn now what happened. I don't know what happened to Alex (Albon), actually. And I'm sure we'll understand it," the Austrian added in the aftermath of the Canadian Grand Prix.
