    Delving into the tiniest details that make up the current Mercedes F1 car, as seen at the Austrian GP

    The trademark of the recent Mercedes F1 cars are the hugely complex bargeboards. All aimed to manage airflow around and under the rear of the car
    Also unique this year is the vane under the nose, known as the 'cape'. This is just a vortex generator that sends a spiralling airflow behind it to power the bargeboards
    New in Austria was this little slot in the tail of the 'cape', it makes the vortex effect even stronger.
    For years Mercedes have run a serrated windscreen, initially run by Rosberg. Hamilton and now Bottas use it. It reduces the buffeting suffered by the drivers head.
    A simpler mirror pod than used earlier in the season, the small hole is for a infrared camera that reads the front tyre temperature
    Inside the shark fin is a cooling outlet, this removes heat from the radiators and dumps it over the top of the rear wing
    Triple exhaust, the large central pipe is from the turbo, the small pipes are from the wastegates. While the last 100mm is straight and formed from inconnel metal sheet, the middle section is 3D printed to get the squashed shape!
    T-wing, this sits in within an area expsed as a loophole in the rules. It simply adds downforce, but can do so with less drag than the rear wing.
    Rear wing endplates feature these slots, they cut down the drag inducing vortex that we see as vapour trails on wet days
    Tail lamp with a very 50's looking visor over the top
    Front wing much of this shape and complexity is to push the front tyre wake from the car. Only the span with the #petronas logo is really creating lots of downforce
    Mandatory F1 cameras pods are mounted on twisted stalks to reduce the aero obstruction they create
    Roll Hoop, larger than most, the middle inlet feeds the engine's airbox, while the outer inlets feed coolers mounted over the gearbox. the actual roll structure is the middle "V" shape, the outer rounded shape is just added on after
    Hydraulic passive suspension trickery is still mounted in the sidepod. Note the green 'gloop' to seal the hydraulic lines passing into the cockpit area
    More hydraulic systems in the other sidepod
    A single brake fluid reservoir sits inside the nose
    With diffusers even larger and more powerful this year, the outer flap detailing is becoming ever more complex to accelerate more under the floor for more downforce
    Bargeboard details, every slot and edge rolls off a vortex to direct the airflow the way the designers want it to go
    More of the front wing, the arched section rolls up a powerful vortex to push the turbulent tyre wake away from upsetting the rear of the car
