Formula 1 is preparing for further rule changes as the FIA pushes to mandate another drop in downforce for the second year of the new formula in 2027. The governing body is reportedly targeting a reduction of 20 to 50 points of downforce by banning several rear aerodynamic elements to improve hybrid energy management and reduce dirty air.
A Looming Development War
Mercedes technical director James Allison recently cautioned that writing rules to slow down Formula 1 cars will not stop engineers from finding ways around them. Speaking on the NU Silver Arrows Radio Show podcast, Allison confirmed the scope of the proposed aerodynamic restrictions while addressing the upcoming development war.
Allison stated that the cars will lose a significant amount of downforce from the new regulations. He noted that the FIA has made a strong effort to pull downforce back to the start of the 2026 era.
Historically, Formula 1 constructors respond to rule changes limiting cornering speeds by spending heavily in wind tunnels to recover lost performance. Allison questioned whether teams will simply accept the cuts or work to recover all the lost downforce, indicating that his team intends to keep pushing.
