It is a move that has been viewed by some as the ultimate way to wind up its rival - in showing that it believes it can make work designs that its competitor could not.
And based on the form showed by the RB20 in last week’s test in Bahrain, all the indications are there that the world champion squad has already unleashed plenty of performance from it.

But rather than it going the Mercedes route to prove a point, the reality is that Red Bull was actually initially resistant in taking on board its rival's previous ideas for its engine gulley and sidepod inlets.
As its technical director Pierre Wache has explained, there are emotional aspects at play when it comes to copying ideas other teams have come up with over something that you have created yourself.
Asked if he saw a certain irony in Red Bull taking on the Mercedes ideas, Wache told Autosport: “I don't see it in this way, I see it more in another way.
“You try to not be emotional [with design choices], as the first reaction is, ‘ah, it's better to have your own ideas.’
“But at one point you just have to take a step back and say, 'is the stopwatch and our system saying what's better?' So you test stuff and you take what is better.
