F1 set for another engine tweak in 2027, and what's this about V8s?

Formula 1 stakeholders have agreed in principle to revise the 2027 power-unit formula.

The plan would increase V6 power and cut electric motor output to improve balance and drivability.

Further tweaks to energy recovery and battery size are also under review amid concerns over the 2026 rules.

The changes are aimed at avoiding performance and safety issues while keeping the next engine era competitive and race-friendly.
