Red Bull Team Principal Christian Horner has remained tight-lipped over whether he believes Mercedes have a new car ahead of the Italian Grand Prix next weekend.
It was reported before the start of the 2023 season that Mercedes had made upgrades and were running a completely different car for the new campaign. However, Red Bull are still running away with it at the top of the Constructors' Championship, having collected 224 points - 128 more than third-place Mercedes.
Aston Martin sit second with Fernando Alonso enduring a terrific season so far, but Lewis Hamilton's Mercedes have struggled despite the change in car. Hamilton is fourth in the Drivers' Championship, with team-mate Russell down in sixth.
