George Russell suggested Red Bull and Ferrari might not be so far ahead of Mercedes when the Formula 1 circus returns from its summer break.
The Belgian Grand Prix will finally see the implementation of the technical directive announced by the FIA in June over porpoising and its effect on the health of drivers. It was due to take effect in France last month, but it has been delayed more than once amid backlash from some teams.
Mercedes had been particularly vocal in their desire for lawmakers to step in, with Russell and Lewis Hamilton among those worst affected by porpoising at the time. The likes of Red Bull and Ferrari, however, had fixed the problem themselves and so did not welcome FIA intervention.
