Reigning champions Red Bull have looked unusually off the pace they set at the start of the year, with main man Verstappen failing to secure a victory since the Spanish GP back in June.
To make matters worse, Christian Horner's outfit were knocked off the top spotin the constructors' standings last week when McLaren overtook them, having emerged as the dark horse of the 2024 season.
Toto Wolff's Mercedes have also experienced their fair share of peaks and troughs, with Hamilton and team-mate George Russell both securing wins amid a deluge of car trouble.
Following the qualifying session at Marina Bay, the FIA confirmed which drivers had had their lap time deleted, in accordance with Article 12.4.1.e of the governing body's International Sporting Code.
Hamilton and Verstappen were just two of the stars who fell victim, along with both Ferraris, adding to the Scuderia's woeful Saturday after last year's winner, Carlos Sainz, crashed out of the session.
A document from the FIA stated: “The cars below did not use the track at turns 2, 11 and 19.”
