Toto Wolff Stands Firm Behind ‘Good as Gold’ Mercedes Amid Challenges

Toto Wolff has moved to defend Mercedes’ reputation in Formula 1 after a run of technical issues with their power units. The Mercedes High Performance Powertrains division, based in Brixworth, has long been known for producing reliable engines.

Since the 2014 introduction of turbo-hybrid engines in F1, Mercedes engines powered the team to eight constructors’ titles and supported seven drivers’ world championships.

However, recent races have seen several Mercedes-powered cars suffer setbacks, bringing questions from inside the paddock.

Problems first became noticeable when Kimi Antonelli encountered engine trouble during his home event at Imola and again at the Spanish Grand Prix. Around the same period, Fernando Alonso was forced to retire from the Monaco Grand Prix while driving for Mercedes-powered Aston Martin.

Mercedes’ own George Russell also faced an early exit from Monaco qualifying due to engine problems, marking a difficult weekend for the team in the principality.

Alex Albon’s retirement for Williams at the Canadian Grand Prix added to concerns about possible recurring issues with the power units.

These retirements across customer teams and the works team have started a discussion about whether a pattern is emerging, especially as the current generation of engine regulations approaches its final year. With several high-profile drivers like George Russell, Fernando Alonso, and Alex Albon directly affected, interest in the situation has intensified.

Wolff, who has been Mercedes team principal since 2013, responded to media questions by pointing to the long-term reliability record of Mercedes engines. He emphasized that, statistically, Mercedes engines have suffered only a minimal number of failures over the last decade.

According to Wolff, Mercedes High Performance Powertrains managing director Hywel Thomas and his staff are fully aware of the recent issues and are working to pinpoint exact causes, particularly analyzing data from the most recent problems at Montreal and elsewhere.

Since turbo-hybrid power units were adopted in 2014, teams using Mercedes engines have benefitted from consistently strong and dependable performance compared to their rivals.

The reliability allowed the Brackley-based team and several customer outfits, like Aston Martin and Williams, to run at the front of the field season after season. The current uptick in failures is new for a manufacturer that has set high standards for over ten years.

Wolff made it clear that while any run of power unit problems is a concern, Mercedes is treating these incidents as learning opportunities. He stated his confidence in the engineering team’s ability to address and solve technical issues before the next round of regulations arrives in 2026.

As the final races under the current engine rules approach, both Mercedes and its customer teams will be working to restore the strong record that has marked the turbo-hybrid era. The challenges in Monaco were particularly notable this season, as detailed during the Monaco Grand Prix weekend.

Meanwhile, the struggles faced by drivers in qualifying at Monaco, including George Russell’s early exit, echoed issues seen by other teams, as discussed in the context of McLaren and Lewis Hamilton’s performance.
