George Russell has ruled out driving style as the cause of his significant pace deficit to Mercedes team-mate Kimi Antonelli after Belgian Grand Prix qualifying at Spa.
Russell qualified 0.508 seconds off Antonelli’s pole lap, with the gap concentrated almost entirely on the straights rather than through the corners.
Earlier in the weekend, Russell had used a vivid analogy to describe his attempts to mimic Antonelli’s technique, comparing it to being asked to draw the Mona Lisa with the original sitting beside you.
However, after reviewing data from qualifying, Russell confirmed that driving style alone cannot account for the straight-line speed difference between the two cars.
“Yesterday I was losing eight tenths in the straights, today I’m losing four tenths,” Russell said, acknowledging the marginal improvement but underlining how much ground remains to be found.
“We thought it was my driving style, with the throttle, and I convinced myself that it was something in me, with the driving style. Now, we’re very confident it’s not the driving style and that there’s a serious issue at play here and the team are working hard to resolve it.”
Russell described the experience of watching his speed bleed away on the straights while running full throttle as deeply frustrating, saying the sensation leaves him feeling completely “powerless.”
“Even my last lap, for some reason I lost another tenth and a half to myself, just on the straight. You’re watching on your steering wheel, just losing speed when you’re full gas on the straight.”
Team principal Toto Wolff echoed that frustration, admitting Mercedes have been unable to pinpoint the root cause despite exhaustive investigation across multiple race weekends.
“George is obviously suffering from lack of straight-line speed, which we are unable to explain, a couple of tenths,” said Wolff, who floated the possibility that a fresher power unit in Antonelli’s car may be contributing to the gap.
Data from qualifying indicates Russell’s primary time loss came on the final straight between Blanchimont and the chicane, with Antonelli’s car running consistently a few kilometres per hour faster throughout that sector.
Race engineer Marcus Dudley identified Turn 14, known as Campus, as a cornering deficit area, but the speed trace shows the gap growing progressively from one tenth to five tenths between Stavelot and the chicane.
The issue first appeared as early as Austria, with sprint qualifying at Silverstone showing a three-and-a-half tenth straight-line loss, yet every suspected fix has subsequently failed to deliver the expected improvement.
“We keep going through this process of we think it’s this. We change it. It’s not this,” Russell said, outlining a troubling pattern that has persisted across multiple rounds of the 2026 season.
The 2026 technical regulations have introduced a complex relationship between driving style and electrical energy management, particularly at so-called energy-starved circuits like Silverstone and Spa where harvesting opportunities are limited.
Mercedes will hope that upcoming circuits with different energy characteristics will help isolate whether the problem is power unit-related or something more fundamental within Russell’s car.
