F1 tech review: The details that proved Haas was no Ferrari clone

The VF-18 was a relatively uncluttered car, the layout of which was predefined by the team’s decision to purchase a huge swathe of parts from Ferrari.

That didn’t make it a copy of last year’s Ferrari as some have suggested though, rather a tribute – as it makes sense to take design cues from the larger teams when operating with less resources and a relatively meagre budget.

Join us as we take a look at some of the similar design elements that may have provoked such indignation and marvel at the complexity of the designs only used by Haas in 2018...

The VF-18’s front brake assembly without the main brake drum attached reveals this crossover pipework which internally feeds air across the face of the assembly from the inlet and ejects it through the wheel face for an aerodynamic gain. Note the teardrop-shaped holes allow heat generated under braking to escape through similarly placed holes in the drum.

A fantastic view of the rear suspension and brake assembly whilst the car is being prepared allows us to see some of the internal ducting to the calipers, etc.

Haas made a raft of changes to the area ahead of the sidepods at the Canadian GP, as the bargeboard's leading vertical element was arched over to meet the chassis (red arrow), stanchion-style cascades were added to the bargeboard's footplate (white arrow). The sidepod deflectors were connected to the bridge slat (blue arrow), while Haas joined Force India in their mirror-mounting approach, using stalks that protrude from the bridging slats leading edge (black arrow).

The team also adopted the straked floor design seen elsewhere on the grid, including Mercedes and Red Bull (inset).

An overview of the VF-18’s front wing from the German GP shows how much effort goes into turning the airflow across and around the front tyre, with the cascade elements set up for aggressive outwash.

Drag reduction is critical at the first two circuits that follow on from the summer break and so Haas arrived with a bow-tie style design in Belgium. A thinner profile in the central part of the wing cuts down on the overall drag created while still allowing for the requisite amount of downforce to be created in the outboard sections.

Changes to the bargeboards and splitter extension were also afoot in Belgium, with the shape and frequency of the serrations in the bargeboards footplate altered, whilst stanchion cascades were mounted atop them (white arrow). Meanwhile, two additional ducting holes were placed on the outer section of the splitter (red arrow).

The edge of the floor was also treated to the longitudinal slots (white arrows) that have now become commonplace up and down the grid too.

Haas courted controversy during the season, having used a floor that had been deemed to contravene the regulations, by virtue of how the bargeboards connected to the splitter (highlighted in yellow). It’s an issue that came to a head at the Italian GP, where Renault protested the design and the team was disqualified from the results.
