Mercedes' Clever Qualifying Trick: High Risk, High Reward
A seemingly bizarre Mercedes maneuver during British Grand Prix qualifying turns out to be an ingenious yet risky method to achieve faster lap times.

After analyzing telemetry data following sprint qualifying at Silverstone, initial confusion arose in the paddock. Kimi Antonelli and George Russell both released their accelerator pedals just before the finish line, seemingly for no reason. It was a striking maneuver, especially given that Antonelli missed out on sprint pole by a fraction of a second—a margin that might not have existed without this unusual action.
However, this seemingly counter-intuitive move was no error, but a clever circumvention of complex energy management rules. Formula 1 regulations mandate a 'ramp down rate,' requiring the battery to gradually reduce its power output along a straight. Consequently, teams cannot always maximize their full 350kW power output all the way to the timing line, but Mercedes found a legal method to extend it longer, yielding a lap time gain of approximately 0.05 seconds.
The core of the trick is that releasing the throttle completely triggers an exception to the 'ramp down' rule. This allows the driver to approach the line at maximum power before bringing energy deployment to zero at the exact right instant. Earlier this season, a similar tactic was attempted using an emergency stop of the MGU-K, but the FIA banned that method due to safety risks. The current approach, where the driver manually lifts off the gas, has been deemed legal.
Execution, however, demands extreme precision from the driver. If the battery reaches zero output too late because the driver failed to lift off in time, it constitutes a technical infringement. This would almost certainly mean disqualification from qualifying and starting from the back of the grid. Russell and Antonelli therefore practiced extensively in the simulator and received an audio cue during their push laps to guide the precise moment to lift.
Now that the method and its benefits are clear, other teams will undoubtedly try to copy it, particularly on circuits where such an advantage could be significant, such as the Hungaroring. It stands as a classic example of a Formula 1 tactic requiring substantial risk for a potential, yet crucial, reward.
