Mercedes is still trying to figure out why George Russell had more energy deployment issues at Formula 1's Belgian Grand Prix despite tweaking his driving style, after he kept losing time to his team-mate on the straights.
Russell's side of the Mercedes garage has been mystified by a lack of energy deployment and hence top speed on power-sensitive circuits, which already manifested itself in Silverstone but was also a big factor at Spa. In Belgium there was a clear top speed deficit between Russell and team-mate Kimi Antonelli through practice and to a lesser extent in qualifying, with Antonelli qualifying on pole and Russell fourth.
