FIA President Mohammed Ben Sulayem has suggested that Formula 1 should be open to multiple options for its next engine regulations, including a potential return to V10s. Formula 1 has not used V10 engines for almost two decades, with the units phased out after 2005, and dropped entirely after 2006.

A return to the V10 engine has been suggested by the FIA President, with sustainable fuels negating the need for hybrid frugality.

The former rally driver has alienated many F1 drivers with clampdowns on jewelry and, most recently, swearing, as well as a refusal to explain what happens to the money the FIA collects as fines. He also ruffled feathers when the FIA opened up the entry process for new teams into the sport and then approved an entry by Andretti Global.
