In recent days, the Brackley-based team has been in the spotlight due to discussions surrounding the power units for next season. Despite widespread rumours suggesting that Mercedes could be the clear favourite for 2026, Toto Wolff has been keen to calm expectations. According to the Mercedes team principal, it is highly unlikely that Formula 1 will witness a level of dominance similar to what was seen in 2014 with the introduction of the turbo-hybrid era.
According to reports, Mercedes, together with Red Bull, may have exploited a grey area in the regulations during the development of their power units. The potential advantage would come from an increase in the compression ratio, achieved through cylinder expansion caused by high operating temperatures. The German manufacturer is believed to have developed this solution with FIA approval, which could translate into a significant advantage next season.
Toto Wolff and Mercedes’ dominance
Mercedes team principal Toto Wolff has stressed that the feelings within the team heading into 2026 are very different from those experienced before the 2014 season. That year marked a major regulation change with the introduction of turbo-hybrid engines, and the Brackley squad went on to dominate its rivals for almost the entire technical cycle.
“Heading into 2014, I already had good feelings during the winter,” Toto Wolff told the media, as reported by Motorsport.com. “The engine seemed more reliable than the others.” When comparing that period to the current winter break, he added: “I would say there is no comparison. The grid is also far more competitive now than it was in the past.”
Toto Wolff revealed that the team is currently meeting the targets it has set itself. However, the real question lies in whether those objectives are the right ones. “Whether these targets are ambitious enough, or whether they are correctly prioritised, only time will tell,” he added.
The opportunities of the new regulations
Mercedes has struggled to deliver consistently strong performances since the ground-effect regulations were introduced in 2022. On the positive side, the driver line-up offers reasons for optimism, with George Russell arguably at the peak of his career and Andrea Kimi Antonelli already showing that he has the speed required to compete in Formula 1.
If the engine does indeed represent a significant advantage, with some suggesting a gain of up to three tenths of a second per lap, then a major opportunity could open up for Mercedes in 2026. The new cars will take to the track for the first time in Barcelona at the end of January, when teams will finally be able to gather their first real benchmarks and assess the work done on their respective projects.
