  • Formula One bosses have agreed to implement immediate changes to the sport's regulations following significant pressure from drivers, particularly four-time world champion Max Verstappen.
  • The adjustments are set to debut at the upcoming Miami Grand Prix on 3 May.
  • Key modifications include reducing energy harvesting from eight to seven megajoules and increasing the hybrid power unit's output from 250kw to 350kw, allowing drivers to push harder for longer.
  • Safety concerns, highlighted by British driver Ollie Bearman's 191mph crash in Japan, have prompted action, with the boost button now capped at 150kw and the MGU-K will be set at 350kw in straightline zones and 250kw when not in a straightline zone.
  • Further discussions are anticipated after the Miami race, as F1 chiefs acknowledge these initial changes may not fully address all driver concerns.
