F1 cars could be extremely loud again in just four years

• FIA president Mohammed Ben Sulayem has proposed that Formula One could return to V8 or V10 engines as early as 2029, utilising fully sustainable fuel.
• The move away from the current 1.6-litre V6 units is suggested to reduce the high costs and complexity associated with their development and maintenance.
• Ben Sulayem highlighted that a return to V8s would offer significant commercial benefits, weight advantages, and a more appealing sound for fans.
• The FIA president also discussed expanding the grid, emphasising the need for more cars rather than more races, with a 12th slot potentially open for a new team.
• Any new entrant, such as a possible Chinese team, must genuinely add value and contribute to the sport's sustainability, following General Motors' Cadillac brand joining as the 11th team next season.
