Jolyon Palmer has analysed the qualifying laps of both Verstappen and Perez, and pointed to the raising of the rear ride height for the bumpy track as the main culprit for Red Bull's struggles in Singapore.
The Singapore Grand Prix marked a surprising turn of events, the first time in five years that neither Red Bull driver advanced to Q3.
While the team had forewarned of potential struggles ahead of the weekend, the extent of their difficulties caught everyone off guard, especially following their record-breaking dominance in previous races.
On Saturday, Max Verstappen was pushed out of the top 10 by Liam Lawson, while Sergio Perez found himself in 13th place, which left many to speculate about the impact of a recent technical directive aimed at curbing flexible bodywork.
However, Christian Horner and the team staunchly asserted that this directive had no bearing on the car's performance. Palmer, having scrutinised the lap times of both drivers, agreed.
He said: “What it appears to be is a ride height issue.”
“Because of the bumps in Singapore they've had to raise the rear ride height, and that has lost them a bit of their aero platform and they've lost a bit of the ground effect.
“[Which] is what is integral to keeping that Red Bull so pinned, and have so much downforce in the medium speed corners particularly.”
