Russell trails team-mate Antonelli by 18km/h in straight-line speed at Silverstone

George Russell will start Sunday’s British Grand Prix at Silverstone from fourth on the grid, hampered by a straight-line speed deficit that left him 17th-fastest in the qualifying speed trap at just 299.8km/h — nearly 18km/h slower than Lewis Hamilton’s benchmark of 317.9km/h and 2.8km/h adrift of pole-sitter and team-mate Kimi Antonelli’s 302.6km/h.

The result extended a difficult weekend for the Briton, who had already qualified fifth for Saturday’s sprint race before finishing fourth behind winner Antonelli, Hamilton and McLaren’s Lando Norris. Russell won in Austria the previous weekend, but the momentum from that result has failed to carry over to Silverstone.

“All weekend we’ve been losing lots of time in the straights,” Russell said. “Yesterday in SQ3, it was almost three tenths I lost in the straights. Again, today in qualifying, if you look at the speed traps, it’s 3km/h down in the middle sector, 6km/h down in the last sector, compared to my team-mate and compared to the McLaren cars.”

Mercedes have been working to identify the root cause. Russell revealed the team believed they had found the issue on Saturday morning, suspecting brake lock-ups, but remained unconvinced that was the full explanation. Only Alex Albon’s Williams sits below Russell among Mercedes-powered cars in the speed trap.

“The team are working super hard to understand why that is,” Russell added. “We thought we found the problem this morning and we thought the brakes were locking on, but we’re not convinced that’s the issue. It just compounds everything when going into the session knowing you’re at a bit of a disadvantage.”

A Q1 lock-up into the barrier at Luffield — which caused no damage — further illustrated Russell’s lack of rhythm across the weekend. He was candid about his prospects for Sunday, acknowledging the speed deficit would have cost him pole regardless of other factors.

“It just looks like I’m running more a draggier car,” he said. “I wouldn’t have been on pole, for sure, but I definitely would have been higher up yesterday. I’ve just sort of felt on the back foot coming into today and I’ll do my best tomorrow to get on the podium.”

The struggles are part of a broader pattern for the pre-season title favourite this season. Russell heads into round nine 43 points behind championship leader Antonelli, with his inability to string together consistent weekends proving costly in what is shaping up as a tight intra-team battle.
