Williams Racing is set to remain powered by Mercedes engines through 2026 as part of the extended partnership between the two teams. Williams Team Principal James Vowles has expressed his confidence in Mercedes’ ability to provide a top-tier power unit under the upcoming 2026 Formula 1 regulations, which will emphasize greater electrification and the use of 100% sustainable fuels.
Mercedes has supplied engines to Williams since 2014, when the hybrid power units were introduced, and the partnership has been renewed for the next generation of engines. Vowles believes Mercedes is well-prepared for the 2026 regulation changes, stating on the F1 Beyond the Grid Podcast that the German manufacturer has done an “exceptional job” in developing their new power unit.
Vowles suggested that the new engine regulations could bring significant differences between power units, unlike the relative parity seen today:
“I think you’re going to see differences between power units that do not exist today. Today, pretty much all the power units are much of a muchness. I think that will change in 2026, and you’ll see a difference between the power units.”
He compared the potential advantage of the new Mercedes engine to the remarkable performance the team displayed in 2014 when the hybrid era first began. However, Vowles tempered expectations by noting that the advantage won’t be as extreme as it was then:
“It won’t be at the levels you saw in 2014, where there was such a widespread throughout the field.”
Despite that, Vowles remains optimistic that Mercedes will offer a competitive advantage, and Williams is aiming to capitalize on this as they continue to rebuild their team with hopes for a more competitive future.
Williams driver Alex Albon, who has signed an extension with the team until the end of 2026, echoed Vowles’ hopes. Albon is looking forward to the new power units providing a boost for Williams and possibly creating gaps similar to those seen in 2014:
“I hope Mercedes has a strong engine and good battery efficiency. That could work in our favour in the Constructors’ comparison and make us relatively competitive with teams with other engines.”
Albon is hopeful that Williams can leverage the new power units to gain a competitive edge in 2026 and continue their upward trajectory into 2027.
The next-generation Mercedes engine is expected to play a key role in Williams’ strategy to climb back up the F1 grid, with both Vowles and Albon optimistic about the team’s future prospects as they head into the new era of Formula 1 regulations.
