Overview
- Lewis Hamilton set the fastest time in the only practice session on Friday with a 1:29.260 lap, putting Ferrari ahead of Mercedes' Kimi Antonelli in FP1 and giving home fans an early boost.
- Mercedes still lead the championship with Kimi Antonelli holding the drivers' lead after a string of wins, while George Russell carries fresh momentum after winning last weekend's Austrian Grand Prix and moving into second in the standings.
- Silverstone's high-speed layout offers few chances to recharge hybrid batteries so energy harvest and deployment are expected to shape results more than raw top speed for much of the weekend.
- The FIA has been reported to cut the maximum hybrid harvest per lap from 7.5MJ to 6.5MJ, a change that teams say will alter how drivers lift, coast and recharge the battery around fast sections.
- With sprint format limiting track time to a single practice, teams must validate upgrades and energy strategies quickly so the weekend will test Mercedes' battery fixes, Ferrari's power‑unit shortfall, and which drivers can manage energy and reliability over a race distance.
