Formula One (F1) begins its new era in Australia with a significant shake-up in the 2026 season, with the first time in decades the chassis and power unit regulations have changed simultaneously. This could pose a challenge for the biggest teams, with near parity between the electrical and combustion engine elements. The last time Mercedes dominated the sport was in 2014, but this time the campaign could be more open. There are also questions about how fans will respond to the changes, with speculation suggesting Ferrari could win a record eighth drivers' title.
