Russell: Mercedes Facing a “Different Beast” in Hungary After Spa Energy Issues

Mercedes’ Spa problem carries less weight in Budapest

George Russell believes Mercedes is dealing with a “different beast” at the Hungarian Grand Prix, meaning the energy-management problem that compromised his Belgian weekend should have a far smaller effect at the Hungaroring.

Russell spent the Spa weekend reporting a lack of straight-line speed. Mercedes attributed the deficit to a software error that prevented the car from retaining enough energy for the second half of the lap. The impact was particularly clear in qualifying, where Russell lost 0.4 seconds to teammate Kimi Antonelli in that section alone.

Mercedes has since addressed the issue, as reported in our earlier coverage of the team’s fix for Russell’s Spa deployment problem. However, the circuit change itself also alters the performance picture significantly.

Hungaroring offers a different energy challenge

Spa was described as an energy-starved circuit, while the Hungaroring provides a much more energy-rich environment. Its stop-start layout and multiple heavy braking zones allow the car to harvest and recapture energy more frequently.

That distinction means a repeat of the same issue would not necessarily produce the same level of performance loss. Russell estimated that, even if Mercedes had carried the identical problem into Budapest, its impact would have been only around 10% of what the team experienced in Belgium.

“I didn’t really look at it, to be honest, because I just trusted in the team that everything has been resolved,” Russell said. “Even if we had the exact same issue as last week, the difference would have probably been 10% of what we saw last week, just because of the nature of the circuit.”

Mercedes still has work to do

The change in circuit characteristics has not immediately transformed Mercedes’ pace. Russell was slightly behind the leading Ferraris in both Friday practice sessions, while he and Antonelli found the car far from satisfactory.

Russell also highlighted the demands placed on the power units and rear tyres at the Hungaroring, saying they produce 350kW out of all the corners while the rear tyres are heavily worked around the lap.

“This weekend is a totally different beast,” he explained. “We’ve got work to do as a team, and for both Kimi and me, the car was far from great, to be honest.”

Wind may provide another variable before qualifying. Russell said conditions were particularly gusty on Friday and expected the direction to shift from Friday to Saturday, potentially changing the car’s behaviour and the competitive order.
