Mercedes-AMG F1 W09 rear detail 1 / 17 Photo by: Giorgio Piola A look at the W09’s exhaust layout sans cover, enables us to see the tortuous route that it must take in order to arch over the rear leg of the suspension’s upper wishbone. To keep the bodywork in this area compact, the wastegate pipes have, like in 2017, been crushed too.

There are three cooling windows along the spine to release the heat being generated under the cover too. It’s also worth noting the shapely flap that has been added to the trailing edge of the engine cover, which brings both aerodynamic and cooling improvements.

Red Bull Racing RB14 front wing detail 5 / 17 Photo by: Giorgio Piola Red Bull’s front wing is deceptively similar to last year’s solution but features downwardly-curved flap tips.

Ferrari SF71H front detail 6 / 17 Photo by: Giorgio Piola There is a new front wing solution for 2018 but Ferrari also tested this solution on Kimi Raikkonen’s car on Friday, which bears a significant resemblance to what the team used throughout the latter part of 2017.

It’s also worth noting the asymmetric brake duct layout being employed, as both options will provide a differing thermal reaction with their respective wheel rim and tyre.

Red Bull Racing RB14 bargeboard detail 15 / 17 Photo by: Giorgio Piola RB14’s bargeboards were subject to quite a significant overhaul at the second pre-season test and now feature several metal supports and a large boomerang to help stiffen the entire assembly as its aerodynamic performance was being compromised. Three ‘r’-shaped cascades were also added to the bargeboard footplate extensions at the test. The mirror stalks have been amended for Australia, and are now mounted on the lower sidepod spar that traverses the front face of the inlet.

Toro Rosso STR13 rear bodywork detail 16 / 17 Photo by: Giorgio Piola Toro Rosso has a lower T-Wing mounted on the STR13, which not only features a nice curvature but also a slot along it. Also note the simple monkey seat winglet hung off the rear wing pillar from an inverted swan-neck style support over the exhaust.
