Antonelli sees Mercedes upgrade gains, but flags low-speed front locking

After winning the United States Grand Prix in Austin, Kimi Antonelli said Mercedes was starting to see results and improvements from its Sepang upgrade, although in some areas it was still not delivering as much as expected.

Mercedes was still fine-tuning the package at the Austin race. Introduced at Sepang with a reworked floor and sidepods, the upgrade also brought some front-end locking under braking. Antonelli said the car was strong in high- and medium-speed conditions and had good balance, but continued to struggle with front locking at low speed.
