Lewis Hamilton said the Mercedes W13 has "mood swings" when trying to describe the car's unpredictable form.
At times this season, the Silver Arrows have been well off the pace and unable to trouble Red Bull and Ferrari. That was the case at the Belgian Grand Prix, which saw George Russell take fourth while Hamilton crashed out on the first lap.
But just a week later things are looking a lot brighter for the British pair. They were both there or thereabouts in qualifying for the Dutch Grand Prix, and could have produced better results than fourth and sixth had their final runs not been scuppered by the yellow flags brought out by a Sergio Perez spin.
