Lewis Hamilton and Carlos Sainz sharply criticized F1’s 2026 regulations after qualifying for the Belgian Grand Prix at Spa-Francorchamps, saying the new cars are strong in the corners but too slow on the straights. Both drivers pointed to an about 50 km/h loss in the final sector when the battery ran out, with the problem particularly evident at Spa.
Sainz said the rules should never have been accepted and were “not good enough,” arguing that no one is enjoying qualifying as much as they did last year and that the Spa performance drop showed the regulations should not have passed on the basis of 2022 and 2023 simulations. Hamilton echoed that view and questioned how the current rule set was approved if simulations had already been run in 2022.
Sainz also said the energy-management limits were costing too much speed at Blanchimont and Pouhon, and warned that the first lap would be “tricky and sketchy” with active aerodynamics and close running up Eau Rouge and the Kemmel Straight. Battery deployment is capped at seven megajoules in qualifying, and poor energy retention could put cars at risk of falling under the 107 percent rule on high-speed circuits. Hamilton qualified poorly at Spa and was set to start from the third row, and said he would lean on his long-run pace in the SF-26 as he looked to earn a sixth podium of the season.
