MERCEDES TECHNICAL DIRECTOR WARNS F1 TEAMS WON’T “LIE DOWN” OVER 2027 DOWNFORCE CUTS

The FIA wants to strip 20 to 50 downforce points from the 2027 regulations by banning key rear aero elements, hoping to ease hybrid energy management and cut dirty air. Mercedes technical director James Allison isn't buying the idea that teams will simply accept it.

"All I know is that the cars are going to be losing a bit of downforce from the new regs, more than a bit," Allison said on the NU Silver Arrows Radio Show. But he made clear the engineers at Brackley won't lie down. The FIA writes rules to slow cars down; teams spend millions in the wind tunnel to claw it all back. It's been that way forever.

Given Mercedes' massive step forward in 2026, Allison's warning carries weight. The 2027 development war is already on, and the teams have no intention of letting the FIA win this round.
