The detail changes that stand out on the new Haas F1 2023 car

Haas became the latest team to reveal its 2023 Formula 1 car on Saturday when it published images of the new VF-23 ahead of a shakedown run at Silverstone.

And whilst there are no real surprises in its DNA, there's plenty of detail for us to pick over when comparing it to last year's challenger and some of its competitors.

At the front, the video showing the VF-23 rollout from the garage has revealed a change to the ratio of static and moveable sections of the front wing flaps. There is more surface granted to the static section beside the nose this season when compared with last year's challenger.

Meanwhile, the upper flaps are more unloaded in the outer section than previously was the case, with them also being narrower as they meet with the endplate.

The endplate itself also differs from last year, with the leading-edge knuckles having been abandoned and the dive plane's shape and position also different from last season.

As all teams search for ways to save weight, it would appear that Haas has been able to remove some of the bulk from its nose assembly. However, with limited access to images at this stage, it could simply be a parallax effect.

A reduction in the underside bulk of the nose (blue arrow) would also have aerodynamic benefits, with more space for the airflow to move along the car's centreline.

As we move further rearward, we can see the obvious comparisons that will be drawn between this year's Haas and last year's Ferrari, which is a common trend for the team given the synergy shared between them in terms of the components that are purchased from the Scuderia.

Nonetheless, the team has continued to build upon the bathtub-style sidepod design, a feature that it had already appropriated during the course of last season. This includes the shape and position of the upper surface cooling gills, which have been moved further down inside the bathtub section than they were in 2022.

One standout difference in the overall design of the sidepods is the shape of the inlet. Whilst Haas has taken the general wide but shallow approach that Ferrari did last season, it has also incorporated a retracted upper leading edge on the VF-23.

This bears some similarity to what we saw from Red Bull last season, albeit not as retracted as the RB18.

The rest of the sidepod is an optimisation of last year's concept, with a steep undercut beneath the front of the sidepod, a relatively flat flank and an overhanging tail section to help direct the airflow toward the coke bottle section at the rear.

You'll also note further Ferrari inspiration at the front of the floor, as Haas has adopted the two-tier step section that was worked into the F1-75's DNA during the course of last season.

The team has also reworked the engine cover and shark fin bodywork, with more of the fin exposed due to the more tightly shrink-wrapped bodywork below it.

You'll also note that the team has cut the fin into two stages, whilst also retaining the detached dorsal section it had in 2022 (yellow line, inset and 2022 in the smaller inset for comparison).

The pronounced hump in the bodywork below the dorsal fin appears to be in line with the solution we saw from Alfa Romeo in 2022, whereby the exhaust has a kink in it in order to clear the suspension arrangement beneath it, suggesting that both Haas and Ferrari have made that switch for 2023.

The floor edge detail isn't exceptionally clear from the available images but, like the real-world solution seen on the Alfa Romeo, it appears to be close in lineage to what we've seen in 2022, albeit with the relevant geometrical alterations to be compliant with the new regulations.
