The upcoming 2027 Formula 1 engine regulations are set to significantly impact the performance and development strategies of each manufacturer. The 60-40 power split, with a 50kW increase in internal combustion engine (ICE) power and a 50kW reduction in electrical motor power, will have varying effects on the teams.
Mercedes
Mercedes is likely to have the least to lose from these changes. Their ICE is already performing well, and the increase in fuel flow rate should enable them to meet the new power targets. The MGU-K's performance is less critical due to the ICE's strong output, and the compression ratio measurements will have a minimal impact. Mercedes' sustainable fuel formulation and power density will play a role in their ability to meet the 50kW increase.
Red Bull-Ford
The Red Bull-Ford alliance has made impressive strides with their first F1 powertrain. With their ICE operating between 10-15bhp behind Mercedes, they have a chance to make up the 50kW gap with additional fuel flow. The reduction in MGU-K power will also ease the strain on their electrical system, allowing for better performance.
Ferrari
Ferrari's smaller turbo has been a hindrance, and the 2027 regulations may exacerbate this issue. To overcome the deficit, they will need to consider a larger turbo to increase air compression. The increase in ICE power from fuel flow will further highlight the limitations of their current turbo design.
Audi
Audi's first F1 powertrain has faced challenges in terms of outright power and start-line performance. The 2027 regulations will address the MGU-K power deficit, but the ICE still needs to be optimized. The turbo size is a critical factor in corner exit traction, and Audi's development will focus on maximizing power at the top end.
Honda
Honda's V6 is significantly behind the top-line ICE packages, and the 300kW restriction may not provide much benefit. With a power unit already struggling in 2026, Honda has a lot of ground to make up. The ADUO upgrades will be crucial in improving their performance, but the turnover of staff and the complex relationship with Aston Martin have raised questions about their collaboration.
