Mercedes' ‘Fimney’ shark fin and cooling chimney, which allows hot air a route by which to escape from the car and reduces the amount of apertures that need to be opened up at the rear of the W08.

There's plenty of detail to look at at the rear end of the W08, especially the diffuser, which has been increased in volume for 2017 as per the new regulations.

A view of the displaced upper wishbone on the W08, enabled by the use of the upright ‘horn’. You’ll also note various surface geometries that tease the airflow as it passes around the brake duct, shaping the wake generated by the front tyre.

A peek into the W08’s cockpit and a fantastic view of the steering wheel, with its numerous buttons and rotaries which control all of the power unit settings.

The serrated windscreen was used primarily Nico Rosberg over the last few seasons at Mercedes - both both of the German team's drivers are using it this season. The windscreen limits the amount of buffer on the driver's helmet but can also be used as a tool to improve aero and cooling. The designers take into account the design of the driver's helmet when shaping the windscreen in order that the air is displaced around it more efficiently while being pushed into the airbox's path.

The 2017 version of the ‘Bat-wing’, mounted astride the ride height sensor, features a much more complicated winged section, with a Z shaping. The pre-bargeboard, which is broken up into three sections, is also mounted on three protruding strakes, which look very similar to the W-floor used last season.

Ferrari has reacted to the warmer climes of Bahrain by expanding its cooling outlets alongside the cockpit, with several more fins used to control the heat as it escapes. These fins are furnished with notches in order that they change the shape of the rejected hot air as it mixes with the airflow passing over the sidepod.

Ferrari’s new front wing has several new features, including a full length slot in the mainplane, revised flaps and a more pronounced arch at the outer section.

Ferrari SF70H triangular splitter extensions

The triangular floor section used ahead of the main floor on the SF70H in order to comply with the regulations features a fully enclosed hole (arrowed), moving airflow from the underside of the surface into the flow stream that moves around the sidepods undercut.

The much-talked about Ferrari floor fin is not a fully-enclosed hole, as is now allowed but a slot that perforates the edge of the car's floor. It's been a talking point as footage from the last few GPs has shown the fin fluttering, leading to a question mark over whether it be deemed too flexible.

The mid-section of Ferrari’s floor has a pronounced step, which seemingly covers the conduit that was previously more exposed during the pre-season tests. It’s understood this has been done to add rigidity and offer a more consistent aerodynamic surface.

The rear end of the SF70H is complemented by a monkey seat, while the twin rear wing mounting pillars have gold leaf applied in order to reflect the heat being generated by the exhaust.

Ferrari’s floor ahead of the rear wheel is supplemented by three L-shaped slots in order to deal with the issue of tyre squirt - a phenomenon whereby airflow is spilled off the rear tyre and pushed laterally into the diffuser, robbing it of consistency.

The overlapping turning vanes utilised by Ferrari in 2017, the forwardmost of which is connected to the side of the nose, while the rearward one is connected to the underside of the chassis.

Red Bull mounted a large kiel probe array at the rear of the sidepods during free practice so as to collect data on how the air is moving down and around the car.

The front of the RB13’s chassis is cutaway, much like last year, in order to improve access and installation of the suspension components.

A mechanic eagerly awaits one of his drivers to practice a nose chance. Note the rearward-facing slot at the base of the nose's ‘thumb’ extension, which mirrors what is seen at the front. Also note the small slots in the base of the two penultimate flaps before they start arching outward.

Flo-viz paint applied to the leading edge of the brake duct and suspension elements so that the team can investigate whether the parts are operating as expected.

Flo-viz paint that’s been applied to the leading edge of the brake duct and suspension elements has splattered on the bargeboards of the car. The team also painted some flo-viz on the sidepods to check they’re operating as expected.

This shot of the front wing shows the level of detail present on the VJM10. Two distinctly different canards are hung from the endplate looking to set up airflow structures that'll help the airflow across the front face and around the tyre.

Force India's bargeboards now feature nine serrations in the upper surface rather than the previous four (red arrows) and the pre-bargeboard (white arrows) has been lengthened extensively. The airflow conditioner that ordinarily wraps around the front face of the sidepod has been curtailed too, replaced by a stubbier appendage that meets with a vortex generator just a few inches from the sidepod's shoulder, framing the airflow around that corner.

The front end of the Force India chassis has been cut away in order to improve accessibility and packaging of the ‘heave’, or third suspension element.

Note the use of a brake disc with five drill holes across the face.

Scuderia Toro Rosso STR12 bodywork detail

The STR12’s longitudinal floor slot takes advantage of the regulation changes that now allow fully enclosed holes 100mm from the floor's edge.

This is the front wing specification used by Haas in China - note the upper flap configuration features two tall chord flaps.

For the front wing trialled in Bahrain, there's a new upper flap arrangement, with three shorter chord flaps occupying the same space as the two previously used.

The VF17’s front suspension has commonality with Ferrari - the team from which Haas purchases its components.

The stripped-down MCL32 of Stoffel Vandoorne gives us a window into the layout of the Honda power unit and ancillary components. You can see the various radiators stacked within the sidepod and numerous pipes fed down from the airbox to the engine and oil coolers.
