The FIA has revealed that an agreement has been reached for rule adjustments to be implemented in the 2027 and 2028 Formula One seasons. The key modification involves the distribution of power between combustion and electric components in the engine, transitioning from the current 53/47 split to a 60/40 ratio in two years.
According to the FIA statement, discussions among the FIA, FOM, Teams, and Power Unit Manufacturers have led to a consensus on changes to the Formula 1 Technical, Sporting, and Financial Regulations for 2027 and 2028. These adjustments aim to tackle concerns related to energy management within the new Power Unit structure while maintaining the thrilling racing action seen under the current regulations.
The planned modifications will gradually rebalance the contributions of the Internal Combustion Engine and Energy Recovery System over the 2027 and 2028 seasons. They include targeted enhancements to internal combustion engine performance, fuel energy flow, and energy recovery system deployment, along with enhanced flexibility in energy management strategies.
Initially proposed for full implementation before the 2027 season, the changes faced resistance from some power unit manufacturers, leading to a compromise agreement. As a result, the adjustments will be phased in gradually rather than all at once.
The revisions are expected to reduce reliance on the battery, addressing issues like performance degradation at the end of long straights. These changes aim to enhance the overall racing experience without compromising the excitement of Formula One competition.
