At the Spanish Grand Prix, Red Bull appeared with changes to the floor's edge wing and the diffuser, using features widely seen on competitors' machinery.
These were most likely spotted by Adrian Newey on his regular grid walks before the Milton Keynes-based squad applied its own twist on a couple of solutions others have used for some time.
Having been proof tested on the opposition, it implies that these should add performance without even needing to be run extensively in CFD and the wind tunnel, given they've both been used for some time by several teams and optimised extensively by them.
Nevertheless, it's not as simple as cutting and pasting the solution from what is used elsewhere.
The concepts need to work in tandem with the existing architecture that Red Bull has in place, with the team creating its own branch in the development tree that will likely be optimised further as the season unfolds.
