Gallery: Key F1 tech shots at the Brazilian GP

A great shot of the newer specification front wing from beneath shows the level of detail that goes into guiding the airflow to improve the pressure field. The shape and thickness of the under-wing strakes change in accordance with the shape of the mainplane they’re connected to and in line with the transition of the slot in front of the outer three.

Head-on shot of the SF70H’s front wing, with the newest specification introduced in Austin, featuring several revisions, including a change to the footplate, endplate and the slots in the mainplane.

A development front wing for Williams, with the base position of the ‘r’ cascade moved back. The thickness of the second and third elements of the mainplane have also been increased.

Another shot of the SF70H’s front wing from beneath. A wider angle allows us to see under the nose too, where an optical ride height sensor is being employed for practice.

Haas F1 Team VF-17 nose and front wing detail

The newest specification of front wing employed by Haas this season, complete with wedge-shaped flap tips.

Scuderia Toro Rosso STR12 front wing detail

It's worth noting that Toro Rosso introduced the slot in the upper mainplane section near the Y250 section quite early in the season, something since copied by McLaren.

The VJM10 with very little bodywork or the floor attached exposes numerous details about cooling and sidepod and power unit packaging.

Sahara Force India VJM10 front wing detail

The close-up of the VJM10’s front wing shows the level of complexity involved in shaping the airflow ahead of the front tyre. The designers have completely compartmentalised the outer section, creating an exaggerated tunnel in order to deal with tyre wake. Note that none of the outer sections of the wing have been painted either.

Both front wing specifications available to the Williams drivers in Brazil.

A close-up of the rear of the W08 shows not only the cooling configuration being used in Brazil but also how the rear suspension is designed to give clean flow over the diffuser.

Renault introduced these bargeboards a few races ago, albeit not racing them on their first arrival. They include a secondary pre-bargeboard, stubby vertical dividing vanes between the primary pre-bargeboard and main bargeboard's footplate and revised louvres in the footplate.

Mercedes is utilising more cooling for Brazil, with a more expansive outlet used around the forwardmost leg of the upper wishbone.

Renault Sport F1 Team RS17 airbox detail

Small pitot tubes mounted on the RS17’s central airbox/rollover spar will measure airflow in the region during free practice, as the team makes preparations for the inclusion of the Halo next season.

Renault Sport F1 Team RS17 barge board detail

Nicknamed the 'aerocat' by the team, this styled sidepod airflow conditioner has been a feature of the car since its launch.

A look at the diffuser on the Mercedes W08 including the wrap around Gurney flap extensions.

Renault Sport F1 Team RS17 front wing detail

An unusual angle of the RS17’s front wing gives a good shot of the canard mounted on the inside of the endplate and the strakes that guide flow on the underside of the wing.

The clutch paddles on Felipe Massa’s car which, much like the ones already utilised by Mercedes and Ferrari, feature a mechanism that improve the driver's relationship with the paddle. In this case a pincer-style arrangement is favoured, rather than the enclosed version used by the aforementioned.

Found on the edge of the RS17’s floor, this extra floor scroll flap improves circulation in that region.

The strakes mounted to the underside of the W08’s front wing help control the airflow ahead of the front tyre.

Close-up of the RS17’s diffuser, which has been the subject of intense development this season, primarily at the outer section, where the detached Gurney extensions are now used to form the outer wall.

Renault Sport F1 Team RS17 exhaust detail

Looking down the barrel of the gun, so to speak, the rear wing's centre mounting pylon intersects the exhaust - a design idea first introduced by Toro Rosso.

Mercedes bargeboards, which were revised just a few races ago and now include more aggressively-shaped and outturned vanes, stand upon their serrated footplates.
