There’s a major element of F1’s 2026 rules changes that’s barely been talked about. And that’s because it just seems to be working
The focus on Formula 1’s rules revolution for 2026 has mainly been on the move to bigger batteries and the related consequences. Amid discussions on energy-starved cars, super clipping, qualifying, and a shift from the 50/50 split, the switch to advanced sustainable fuels has been overshadowed. Sustainable fuels are a key aspect of F1’s 2026 rules revamp, boosting green credentials and paving the way for ‘old-school’ engines to return in the future. This shift allows V8 engines to potentially make a comeback by 2031, marking a significant technological advancement. Despite the positive shift towards sustainable fuels, the attention has largely been on the electrical element, with fuel advancements often overlooked. Fuel quality directly impacts the energy output of internal combustion engines and thus influences battery performance, making it a crucial component of F1’s transformation.
