F1 tech review: Charting Alfa Romeo’s slide down the order

Alfa Romeo slipped down the Formula 1 pecking order when compared with its championship finish in 2022, so let’s take a look at some of the car’s technical details and how the team developed its car.

Alfa Romeo teased everyone with its launch render at the start of the season, as the floor edge featured a series of winglets, a design that would never actually see the light of day.

The C43’s front suspension featured a chassis blister around the front suspension elements to work better with the fairings and improve flow downstream.

Detached from the car we’re able to better see the detail of the rear crash structure, brake duct winglet, rear suspension and rear wing.

The C43 presented without the sidepod and engine cover bodywork exposes the packaging of the radiators, the power unit and many of the other ancillaries.

The forward portion of the floor is stepped to give more height at the inboard end, as can be seen by the contour line.

Changes were made to the nose and front wing architecture early-on, with an elongated nose tip and mainplane redesign introduced at the Australian Grand Prix.

Alfa Romeo’s high downforce rear wing at the Monaco Grand Prix, with metal inserts in the endplate cutout to help reduce flexion, whilst teardrop-shaped flap pivots are also employed. Also note the semi-detached shark fin that allows more freedom for the cooling outlets on the cover’s spine.

Overview of the C43’s rear end with the beam wing in a bi-plane configuration, with a slatted forward mounted upper element and more loaded lower element. Also note the intricate Kiel probe arrays mounted beside the diffuser to capture data for the team.

The low downforce rear wing configuration features a sawn-off tip section and central mounting pillars.

In the side view, it’s clear to see how the mainplane’s leading edge has also been set back when compared with the endplate, while the pillar’s swan neck design sees them chamfered as they meet the mainplane.

A new floor was introduced at the United States Grand Prix, featuring an elongated edge wing, much like many of their rivals had already unveiled. A scrolled forward section gave way to a twisted central section with an opposingly angled section that was connected to the winglet, which had previously sat in the rear cutout.

Alfa Romeo added a swage line to the outer face of their rear wing endplate at the Qatar Grand Prix, which swoops more steeply than some of the versions seen elsewhere up and down the grid.
