V10 engines were last used in the championship in 2006, just before the FIA outlawed them. Teams shifted to V8 engines from 2007 through 2013, and starting in 2014, they have been using the modern 1.6-litre V6 hybrid engines.

To comply with the FIA’s directive that all championships attain carbon neutrality by 2030, Formula 1 will employ “drop-in” 100% sustainable fuels in 2026.

The head of Red Bull Racing offered his opinions on Honda’s return, pointing out that the company had momentarily departed Formula One in 2020 as they switched their attention away from internal combustion engines.

The hybrid technology used in Formula 1 will continue to be used through the end of the decade despite persistent criticism from drivers and fans. A chance for change was offered by the revised power unit requirements for 2026, but the governing board decided to continue with a modified version of the current V6 hybrid power unit.

Charles Leclerc and Lewis Hamilton, two prominent Formula 1 drivers, have voiced their concerns about the increasing weight of Formula 1 cars and the apparent contradiction with the sport’s sustainability initiatives.

Leclerc expressed his dissatisfaction with heavier cars, stating that he doesn’t favor their handling characteristics. He mentioned that he had the opportunity to drive a Formula 1 car from 2003, and he could feel the significant difference in weight compared to modern cars. Lighter cars tend to handle more responsively and can be more agile, which can be preferred by drivers who prioritize handling and performance.
