Red Bull and Aston Martin are the only two F1 teams to have brought performance-enhancing upgrades to the Azerbaijan GP.
Eight of the 10 teams have brought no performance boosts to Baku, with Red Bull's upgrade concerning the floor of the RB20.
According to Red Bull's official submission to the FIA, the "floor tunnel geometry [is] subtly revised by locally raising or lowering the surfaces."
The team hopes that the "changes applied [will] improve the pressure gradients along the floor to improve the flow locally and downstream in all conditions."
Elsewhere, Aston Martin has brought a new rear deflector to boost load around the bottom of the floor on the right-hand side at the back of the AMR24.
Meanwhile, RB has brought a circuit-specific front-wing featuring a reduction in camber to reduce the overall load created by the front-wing assembly to aid with the balance at the low-drag/low downforce circuit.
