Red Bull's RB19 has been the class of the field in 2023, propelling Max Verstappen and Sergio Perez to a clean sweep of seven wins in the first seven races of the season.
The car has looked particularly planted in high-speed corners but, despite its downforce prowess, the car has also enjoyed a straightline speed advantage over the competition, both with and without DRS.
When asked about the main asset of the car, technical director Wache replied: "Efficiency, I would say. On different tracks, we are able to produce downforce without massive drag, which I think is the main strength."
Rival teams have suggested that Red Bull is compromising its qualifying pace on Saturday to be stronger in the race, and that it is still racking up poles thanks to the size of the advantage it enjoys over the competition.
But Wache refutes suggestions Red Bull has pace in hand. "Not really. In qualifying, for sure we are pushing," he added.
"During the race, as everybody we are saving or managing the tyres to increase the stint length and to give more choice on strategy, like everybody is doing.
"The success is also depending not on you but also on the others. And the difference is bigger than what we expected."
