The updates Red Bull hope will keep them on top at Silverstone


The Silverstone track, where next weekend’s British Grand Prix
will be held, has always represented a crucial point in the season precisely
because of its position on the calendar, preceding the Austrian GP by just one
week, the 11th of 22 races, and the exact halfway point of the F1 World

Nothamptonshire track is particularly technical, characterised by rapid changes
of direction such as the famous Maggotts, Becketts and Chapel corners that the
2022 F1 cars will face for the first time. It is possible that their
speeds through that section of track will be decidedly higher than in the past
thanks to the downforce generated by the current floors that exploit the ground

is also the home track for seven out of ten teams, including Red Bull, based
just a few miles away in Milton Keynes. Currently at the top of both Drivers’
and Constructors’ Championships, the team has overseen a large package of
developments on the RB18, which according to the objectives of the technicians
headed by Adrian Newey, should correct some “minimal” weaknesses of
the car in terms of performance.

Red Bull’s Silverstone updates

There will not be only aerodynamic interventions; in fact,
rumours suggest that many of the car’s components have been redesigned over the
last three months, to obtain a functional and weight optimisation.

The bottom will be new in terms of the construction process, in
terms of orientation of the carbon fibre to ensure maximum stiffness without
the aid of additional tie rods, and in terms of the design of the lower

peculiar feature of this element of the RB18, since its debut, has been the
variability of the sections of the lower Venturi channels, and also the fact
that their internal profile was not continuous, but characterised by evident

the evolution introduced in Spain, this factor became externally visible with
an evident surface hump that conceals a lower vertical profile with the
function of flow diverter.

The optimisation of the lower flows was the basis of the
positive progression of the performance of this car in the twisty sections of
the circuits visited so far, but at Silverstone, the latest evolution should
also represent a solid starting point for the lower aerodynamic concept of the
future RB19.

Red Bull’s understanding of the porpoising phenomenon was
already very good from the beginning of the season, with the current car almost
free from the bouncing that has significantly affected many rival cars.

team has been able to take advantage of data collected from the start of the
season, and has learnt from very accurate simulations that would have defined
the ultimate profile of the RB18’s bottom that will be introduced this weekend.

is significant that this will happen at Silverstone after the introduction at
the Canadian GP of the FIA’s Technical Directive 39.

This was strongly protested by Red Bull and Ferrari, who, albeit
with decidedly different methods and visual results, have both succeeded in managing
porpoising without having to compromise the performance of their cars.

RB18 Floor

The Red Bull floor, from the beginning of the season, has been characterised by a particular profiling of the internal edge of the Venturi channels, with evident steps that determine a specific management of the lower flows. The version that will be introduced at Silverstone will present an even more extreme internal profile in the discontinuities, for a very precise management of flows and underneath pressures.

RB18 Rear Wing

In Baku, there were problems with the RB18’s DRS actuator. At Silverstone, alongside a revised version of the rear wing, a new DRS actuator, an evolution of the current one, should be introduced.
