The team utilised a spoon-shaped rear wing for the Azerbaijan GP, as it looked to reduce drag but also retain a decent chunk of downforce for the trickier second sector.

Changes were also visible at the front of the car, as the team altered the rearmost section of the endplate. [1] New endplate canard, [2] extra slot at the rear of the endplate, with the surface turned aggressively outward and [3] the trailing flap was mounted on the flap stack, rather than the endplate.

Controversy surrounded the Scuderia in Spain, as it introduced a new mirror design (right) that attached to the halo. The upper ‘eyebrow’ winglet was considered erroneous by everyone in the paddock and although it was allowed to race it in Spain, the team would have to revise the design for the next race onwards.

New rear suspension was introduced in Spain, with a more angular connection to the upright it would improve airflow around the structure.

The team made changes at the rear of the car for the British GP, with the now fashionable elongated floor slots placed on the floors edge (highlighted in yellow), whilst the flap on the edge of the floor just ahead of the rear tyre (red arrow) was discarded and the floor just upturned instead. Meanwhile, the rear brake duct fin was swapped for a design that featured full length slots.

The team also made changes to the engine cover, including a centralised valley that altered the movement of airflow around and through the sidepod.

The team also retested the revised position for their wastegate outlets, placing them above the main exhaust. This test coincided with a different rear wing design too, with a raised lip added to the leading edge of the mainplane.

Ferrari introduced a new rear wing endplate design for the Singapore GP, keyed at improving downforce the endplates featured a strake-like design at the rear of their surface in order to work the airflow that little harder. It’s a trick used by McLaren for some time and assimilated by Ferrari’s title rivals Mercedes during the season.

Ferrari introduced a family of new front-end parts at the Russian GP, as it looked to improve all-round performance. The front wing design incorporated the novel footplate solution pioneered by Red Bull in 2017 and tested by Ferrari in Hungary, featuring a raised and inclined footplate that’s also pushed back from the wing’s leading edge enticing the airflow to converge on the vertical slot behind [1]. The turning vanes [2] were also given a considerable amount of attention having been relatively untouched throughout the first part of 2018. The upturned profile on the leading edge of the mainplane [3] was a little more pronounced, altering how the airflow behaved, whilst the furniture [4] on the inside of the endplate designed to control outwash was also revised. Coupled to the change in the mainplane’s geometry and the resultant affect the other changes had on the wing’s ability to create outwash, the flap geometry was also amended. An additional slot was made in the outboard section [5]. Perhaps more importantly though, the team toned down the aggressive transition between the tunneled outboard section of the wing and the flapped region [6].

Ferrari trialled this new floor design at the US GP, featuring three rows of fins at various points along the floor it was never raced. The intention of these fins was to improve how the air flowed through and around the longitudinal slots that had been added earlier in the season.

The team also introduced a revised bargeboard configuration for the US GP, featuring a re-profiled footplate (red arrow) and extra flaps atop them (blue arrow), as it looked to further influence the airflow being received.

The team trialled a 2019-style front wing in Abu Dhabi, a design which was devoid of the main cascade elements and a simplified endplate. This was used by the team in combination with kiel probe arrays mounted behind the front wheels as the team collected data that would help to improve the correlation between the real world and simulation tools.
