McLaren team principal Andrea Stella has called for adjustments to Formula 1 power unit regulations to enhance the series, though he believes meaningful hardware changes are unlikely before 2028. Recent refinements to the 2026 rules delivered modest gains at the Miami Grand Prix. Stakeholders including Mercedes and Alpine have weighed in on the need for lead time and potential tweaks.
Andrea Stella said hardware adjustments are required to improve the sport overall. He pointed to an increase in fuel flow to boost internal combustion engine power and larger batteries to allow more electric energy harvesting, potentially raising output from 350kW to 400kW or 450kW. Stella acknowledged these shifts would be difficult to implement for 2027 due to long lead times for manufacturers and urged agreement before the summer break to enable 2028 changes.
