Later this evening—Friday morning local time—the new 1.6 L V6 engines that power this year’s crop of Formula 1 machinery will roar into life as practice for the first race of the year gets underway in Melbourne, Australia. After several years in which the teams’ performances converged so much that the sport was determined by finer margins than ever, 2026 sees a comprehensive reset.
The cars are smaller and lighter, and they have different aerodynamic configurations for the corners and the straights. The hybrid systems are more powerful, and each runs on its own bespoke sustainable fuel. There’s even a new way to watch as F1 makes a $750 million move from ESPN to Apple. Over the offseason, throughout the preseason shakedown in Barcelona, and then two three-day tests in Bahrain, plenty of questions have arisen: Are the new technical regulations a mistake? Can we still watch F1TV? And just what the heck is going on, Aston Martin?
400 kW + 350 kW = headaches?
After more than a decade with the same power units—and the same few manufacturers—the sport wanted to attract some new blood. Drawing in more car companies, which have boards and shareholders to answer to, required acknowledging road relevance and some commitment to sustainability and decarbonization. Since OEMs are all about electrification, that meant a greater emphasis on the hybrid side of the power units. And the veneer of environmental responsibility arrives in the form of heavily audited, fully sustainable fuels.
