Ferrari F1 engineers gain weight-saving insights from World Endurance Championship team. Ferrari is leveraging lessons from their WEC Hypercar program.

Ferrari taps WEC expertise to boost 2026 F1 car performance

Mercedes are widely regarded as having set the benchmark with their 2026 Formula 1 engine, a consensus that has emerged even before any on-track testing has taken place.

The 2026 F1 power units are undergoing a major transformation, with the removal of the MGU-H in favor of a larger, more powerful battery. The new regulations make the sport nearly 50% electric, while cars will run on sustainable fuels. Mercedes are reportedly trying to downplay expectations about having the best engine, knowing how easily rumors can spread among engineers from rival teams discussing factory testing.

Ferrari could emerge as Mercedes’ closest challengers thanks to their long-standing engine-building expertise. Audi and Red Bull Powertrains are relative newcomers, while Honda only returned to F1 in 2015.

Ferrari learns weight-saving strategies from their WEC program

While Ferrari’s F1 team failed to secure a single race win in 2025, the Scuderia did enjoy notable success in other motorsport arenas, claiming the Hypercar title in the World Endurance Championship. Their 499P Hypercar has won the last three editions of the iconic 24 Hours of Le Mans.

According to Italian media reports, Ferrari has been closely studying the approaches of their WEC counterparts to gain an edge for the 2026 F1 season. The 499P Hypercar uses a 200-kilowatt battery, and the WEC team has provided Ferrari with valuable guidance on reducing battery weight—a factor expected to be a key performance differentiator this year. In previous seasons, Ferrari lagged behind Mercedes in this area.

Although there are significant differences between F1 and endurance racing—the 2026 F1 battery will be 350 kW—the underlying principles are similar. Since Mercedes does not compete in the Hypercar class, Ferrari may benefit from unique insights that give them a potential advantage.

Ferrari could challenge Mercedes over fuel regulations in Australia

Behind the scenes, a dispute has arisen regarding fuel-compression ratios. Ferrari have reportedly lodged complaints with the FIA after Mercedes and Red Bull allegedly discovered a regulatory loophole. Veteran technical analyst Gary Anderson stated that Mercedes are “pushing the limits” of the rules without actually “cheating,” and suggested that rivals are “crying wolf” because they failed to identify the opportunity themselves.

There remains a possibility that Ferrari will file a formal protest against Mercedes and Red Bull after the Australian Grand Prix. However, it is expected that further developments will unfold in the lead-up to the season opener in Melbourne.

This internal technical exchange represents a masterstroke in resource management, allowing Ferrari to maximize its R&D without falling foul of the cost cap. By distilling the endurance-tested weight-saving secrets of the 499P into the DNA of the 2026 F1 challenger, the Scuderia is positioning itself as a leader in technical efficiency. In a sport where championships are won by the narrowest of margins, the lessons learned on the Mulsanne Straight could be the very thing that propels Ferrari back to the top of the Formula 1 podium.
