Unable to use the fully enclosed holes in the floor it had in the previous few years (inset), the team expected these wavy floor sections to help bridge the aerodynamic performance gap. The team also had the Z-shaped floor cutout that many others copied in the opening few rounds of the season [2] but had an upturn to the rear portion of the floor [3] along with numerous aerodynamic surfaces to help direct the airflow mounted above it.

Mercedes introduced a raft of changes for the W12 at the British Grand Prix, mainly focused around the bargeboard cluster, sidepod deflectors and floor. This is the arrangement prior to the changes.

The new aerodynamic package saw the venetian blind-like slats increased in length, with the tall vertical deflector in front of them reduced in height to allow for it. The main vertical deflector beside the sidepod was fully fixed to the floor, whilst the joint between it and the sidepod wing was removed, resulting in an endplate being added to the sidepod wing. The wavy floor that had previously been a prominent feature was also redesigned, with the waves removed, the scroll on the edge of the floor shortened and the flaps behind it split into two. Also note the addition of more angled floor fins between them and the sidepod.

Mercedes evaluated a few rear wing options for the Belgian Grand Prix, with both drivers using similar wing specs during Free Practice, albeit with Hamilton on the lower downforce option of the two, without the Gurney. Entering qualifying, given the conditions, all that changed though, as they both fitted a higher downforce option.

The low downforce rear wing used at the Italian Grand Prix was a one-off used only for the hi-speed nature of the Monza circuit.

Mercedes began trialling a revised front wing design from the Russian Grand Prix but, having been used in a few Free Practice sessions it was never raced. The alterations created a different ratio between the outer static portion of the wing and the moveable flapped section.

The W12’s front brake assembly without the drum cover attached gives us some insight as to where the airflow collected by the inlet is sent. Note the silver duct running across the top of the assembly which has a wide nozzle that delivers the airflow out of the wheel face for aerodynamic gain.

From this angle we can see how that nozzle emerges from the brake duct and can imagine how the airflow mixing with the air rotated by the wheel rim might be affected.

This illustration with the brake duct bodywork attached shows how the drum’s design creates another bypass channel in the lower half of the assembly, allowing the airflow a way of interacting with the wheel rim as it rotates around the brake duct.

Mercedes ran a low downforce rear wing option at Silverstone and Spa but as we can see, while the low downforce rear wing used in Saudi Arabia and Azerbaijan used the single pillar arrangement and took up a similar amount of space in the box region, the upper flap design differed in order to reduce drag.

RED BULL
Red Bull Racing RB16B rear suspension

Red Bull was one of the teams that tested a 2021 specification floor ahead of the season, taking some time to understand the impact the rule changes might have. Its initial design for the RB16B followed the same principles as the test item, with a simple tapered edge. However, a Z-shaped floor was quickly unveiled at the first test to usurp it.

The Z-shaped floor introduced by Red Bull featured a notch between two tapered sections, with an angled strake added on the Z junction in order to help influence the airflow.

Red Bull spent its two development tokens at the rear of the RB16B, with a new gearbox carrier design deployed in order that it could make further aerodynamic gains, also allowing it to repackage the suspension. The changes in the track rod and wishbone layout being altered to improve their aerodynamic packaging (see insets).

Here it is again from the rearward view, with the box section inserted beneath the chassis in order that airflow making its way under the nose is channeled out further down the body of the car without interruption. Also note the ‘S’-duct pipework which carries airflow to the small exit atop the vanity panel.

Changes were swiftly made to the sidepod deflectors in the early part of the season, as the forward-most vertical element was repositioned ahead of the two upper axehead extensions, made full length and an almost full-length vertical slot was added.

The high downforce rear wing used by Red Bull featured a more conventionally shaped mainplane, the sinuous louvres on the overhanging section of the endplate, upwash strikes and a serrated rear cutout.

Red Bull utilised several different front brake duct inlets during the opening few races of 2021 in order to find a balance between the cooling required and the capture of airflow for aerodynamic purposes.

The team added some serrated edges to the outer sections of the Gurney-like extensions that reached around the RB16B’s diffuser at the Monaco GP, but only on Max Verstappen’s car.

Controversy over the use of flexible rear wings reared its head at the Spanish Grand Prix, with it suspected that many teams, including Red Bull, had found a way to subvert the static load tests and gain a straight-line speed advantage.

The teams in question had found a way to tilt the entire rear wing structure back under load, reducing some of the drag being generated.

The low downforce rear wing introduced by Red Bull at the Azerbaijan Grand Prix featured a more pronounced spoon section, owing to the much shallower mainplane in the outer sections. The endplate was also more basic, with the sinuous louvres and upwash strakes removed, while a standard rear upper cutout was deployed instead.
Red Bull RB16B diffuser detail

The team continued to develop the serrated diffuser concept at the Styrian Grand Prix when it added them to the entire length of the two Gurney-like flaps that were sandwiched between the outermost flap and the diffuser wall. The serrations were also added to flap under the crash structure but once again, Sergio Perez was a step behind, as Verstappen’s car was fitted with the new specification first.

Red Bull also began running different front wing specifications between its two drivers as it searched for the optimum setup on cars that were out of kilter in terms of the developments on its cars.

To further enhance the effect that the team was looking for with the floor solution it added a step ladder-like winglet to the RB16B at the British GP. The structure featured three steps that fanned out relative to the angle seen on the other fins and strakes used by the team to help turn the airflow outboard.

This led to the optimisation of the area around the cut out, with an additional angled strake added to create more of a nozzle.

A comparison of the two wing specifications seen at Spa and Monza, with the low downforce option tested at Baku before the team reverted to a top flap specification without the graduated outer trailing edge. The one-off Monza specification was even shallower, as the team looked to reduce drag as much as possible.

Marginally different front wing specifications were deployed on the Red Bull cars in Russia, with the wing on Perez’s car (right) featuring a small Gurney in the upper corner and a slightly different shape to the flap’s trailing edge.

Red Bull started to see some issues arise with the rear wing assembly at the United States Grand Prix, as the bumpy surface at COTA wreaked havoc and cracks appeared in the wings surface that it felt compelled to repair (yellow highlighted sections were areas where the team made repairs). The medium downforce rear wing used at the event would cause them further issues down the line too.

Red Bull took a novel approach to heat rejection from the sidepods on the RB16 and RB16B with the ability to have outlets on the inside of the halo, rather than a louvered cooling panel on the outer face. This obviously has some aerodynamic benefits with the heat released into an area where it will do less damage.

In Mexico these outlets were opened up even more than usual to help deal with the effect that altitude has on cooling the cars.

The ongoing search for performance continued as the team looked to the front brake assembly as a means of making up the difference. In Mexico this led to the team trying various solutions, with not only a different inlet trialled (inset) but also different panels within the bypass section of the drum. Usually it would utilise a full coverage panel which is also painted to reduce thermal transfer. For Mexico it split the panel in order to allow the heat rejected from the brake disc a way to mix with the airflow that usually bypasses it.

As problems with Red Bull’s rear wings persisted it became evident that a combination of fatigue and extra load, owing to the nature of the circuits being visited, was causing an issue with the DRS. A noticeable oscillation of the top flap when DRS was open was apparent, with the actuator and linkages seemingly unable to maintain the gap when DRS was deployed. The team tried various fixes but a solution wasn’t really found and with the actuator and linkages subject to the homologation and token system the team were unable to make wholesale changes.

Repairs being made to the rear wing in Qatar, including the upper corner of the top flap, just around the pivot and the central section of the wing, both front and back.

As a consequence of these issues the team were forced to use the high downforce wing at the Qatar Grand Prix, even though their favoured choice was the medium downforce, which they’d used throughout Free Practice but couldn’t find a way to prevent the DRS oscillations.
