The need for changes in Formula 1 power units is becoming increasingly evident, but the McLaren team warns that making these modifications before 2028 will be a difficult challenge. McLaren’s director, Andrea Stella, has expressed that while the variations are essential to improve competition, the current timing pressures any adjustments to the regulations towards a later date.
Recently, Formula 1 approved a set of refinements to enhance qualifying qualities and reduce extreme speeds in the early races of the new 2026 regulations. The Miami Grand Prix, held last week, served as a test for these new rules, which showed small improvements in performance, although their real effectiveness will be better assessed at circuits with stricter energy demands.
Stella has pointed out that to achieve significant improvements, it will be necessary to effectively modify the hardware of the power units. This could include increasing the fuel flow to boost the power of internal combustion engines or using larger batteries to allow for better energy management. A less impactful alternative would be to slightly reduce downforce levels, which would decrease speed in corners and save energy.
However, any structural change to the power units in terms of fuel flow seems unlikely before 2028, due to time constraints and the complex implications these changes pose for vehicle engineering and fuel infrastructure. Several teams have already planned to maintain their current chassis for the upcoming season, further complicating the situation.
Stella has emphasized the importance of reaching a consensus among the involved parties before the summer breaks, to ensure that the modifications can be implemented for the 2028 season. According to him, the team should find a way to extract more performance from the current engines and exploit the opportunities presented by the regulations, but this requires hardware changes.
On the other hand, the team principal of Mercedes, Toto Wolff, has expressed his willingness to consider minor adaptations to improve the spectacle, arguing that the current category is already operating at a good level. Wolff stated that competition is excellent and that the Best moments of F1 can currently be witnessed, with an outstanding battle for the top spot and in the midfield camp.
Teams need clear and timely information about the technical regulations for 2027 to properly adjust. The director of Alpine, Steve Nielsen, has made it clear that it is urgent to know if a new chassis will be necessary, especially if the changes will require modifying the fuel tank capacity.
