How Red Bull has further improved its dominant RB19 F1 car

The modifications centre around the car’s sidepods, with the shape of the inlet and underbite corrected in order to improve flow to the radiators, coolers and ancillaries housed within. The reshaping will obviously have a bearing on the external flow stream too.

Red Bull has achieved this by widening the aperture and raising the leading edge of the underbite, which alters the aspect ratio, but shouldn’t impact the volume dramatically.

This results in a win-win between its cooling demands and increasing space in the undercut beneath the sidepod to deliver more airflow to the rear of the car.

As a consequence of the bodywork being widened around the inlet, the rest of the sidepod’s geometry has been subtly altered too. This helps take advantage of the additional space afforded to the undercut to improve both the physical interaction with the floor and their aerodynamic kinship.

In order to fully complement it, the geometry of the floor’s edge and the aerodynamic furniture that is mounted upon it have also been subtly recrafted to increase their performance too.

To further capitalise on the efforts here, there’s also a change upstream, with the outer floor fence being massaged on the top edge in order to better align the local airflow and take advantage of the changes made downstream.

Modifications have also been made to the rear brake duct fence, with one of the winglets now split into two, in order to better manage the airflow in that region.

While other teams have introduced new, lower-downforce rear-wing variants for the challenges posed by the Baku street circuit, Red Bull has not, opting to use the solutions that have already proved to be extremely potent this season.

It’s likely it will use a similar set-up to the one used in Australia, in fact, with its lower downforce rear wing option paired with the single-element lower beam wing.

Mercedes lowers the drag

Mercedes also has a package of parts at its disposal in Azerbaijan, as it looks to make up ground on those ahead of it.

There is a mixture of track-specific updates and ongoing developmental components but, given this weekend is the first in a new format that includes just one free practice session and four competitive sessions, the team has opted for smaller alterations, ahead of the introduction…
