Fórmula 1 planeja ajustes nas unidades de potência para a temporada de 2027

As partes interessadas da Fórmula 1 chegaram a um acordo em princípio para reequilibrar a potência das unidades de força a partir do próximo ano. As mudanças visam resolver preocupações com os atuais sistemas híbridos introduzidos em 2026. Os dirigentes também consideram uma mudança de longo prazo em direção a motores mais simples.

A FIA, as equipes, os fabricantes de unidades de potência e a direção da Fórmula 1 decidiram aumentar a potência do motor V6 em 50 kW, chegando a 450 kW, enquanto reduzirão a implementação do motor elétrico na mesma proporção, para 300 kW. O ajuste será feito por meio de limites maiores de fluxo de combustível e deve manter os níveis de carga da bateria mais altos durante as voltas, reduzindo as diferenças de velocidade quando ocorrer o esgotamento da energia elétrica. As discussões continuam sobre o aumento do limite de recuperação do motor elétrico para além de 350 kW e o aumento da capacidade da bateria de 4 MJ para 5 MJ.
