The Middle East war has resulted in the cancellation of several Formula One races due to conflicts, forcing the teams to use this time to further develop their cars. Technical representatives from each team and the FIA are working to resolve problems caused by F1's new hybrid power units, which can use more than a single charge per lap, but most F1 tracks lack enough braking zones for this. The hybrid system can also use power from the engine to charge the battery, like most plug-in hybrid road cars. This could help teams like Aston Martin, Cadillac, and Williams catch up to the midfield. The sport's governing body, the FIA, is working to fix these issues.
