Red Bull have brought one of the largest upgrade packages to Silverstone, despite already boasting a car that is a proven race winner.
In addition to extensive development of the floor, the Milton Keynes squad have also further developed the important aerodynamics on the top of the RB18 – especially the heavily modified lower part of the hood.
This part of the new hood features a deep horizontal sidecut with a T-shaped section. This section covers the internal elements of the RB18's rear suspension. The horizontal part of this section consists of an opening where the warm air flows out of the radiators.
The airflow exiting the radiator enhances the effect of the wings at the rear of the Red Bull car, helping to generate more downforce. That airflow is accelerated, making maximum use of the beam wing, the lower rear wing element. On the upgraded RB18, those airflows are less turbulent than before.
The Red Bull upgrade is therefore an intervention that refines the aerodynamic qualities of the RB18, improving the balance in the car designed by Adrian Newey.
The upgrade will help them to go faster than before through high-speed corners, perfect ahead of a race weekend at the mighty Silverstone.
