Why Hungary’s F1 update was more than just a Ferrari version

After ending up at the bottom of the constructors’ standings last year, her lead with the VF-22 means she heads into the summer break ahead of Williams, Aston Martin and Alpha Torri in the championship standings.

This is an impressive feat when it is seen as the least actively developing one. It’s a testament to the work done with the original design of this year’s car but also to how it worked to make the most of what was at its disposal.

Of the 12 races that preceded the Hungarian Grand Prix, the team made updates in only five. However, all of these things will be considered secondary, especially against the background of what other teams have produced and are still far from in terms of performance.

That’s why there has been so much conspiracy about the major upgrade it brought to Hungaroring, which has led to so many accusations that it is nothing more than a “white Ferrari”.

The conclusions reached by some were that Haas simply copied Ferrari’s progress with its latest update, which is not entirely accurate as he was based on his technical partner’s ideas.

As team boss Gunther Steiner said: “We have the same Ferrari engine, same gearbox, same suspension. Why are we copying anyone else? And they win races? So 1 and 1 equals 2, and we’re not stupid.”

However, where Haas may have been smarter, especially when compared to its closest competitor, is that its evolution didn’t stray too far from its origins either.

Comparing the side solution raced in the first half of the season resident in Schumacher’s car in Hungary (left), with the new solution (center), there is a clear move towards the sporty notch in the Ferrari F1-75 (right) but it remains on the same design proportions.

Meanwhile, teams like Aston Martin and Williams have completely changed their design concepts, following the example set by Red Bull, rather than perfecting and improving the solutions they started the season with.

While it’s clear that we can see the inspiration Haas has drawn from Ferrari on the upper deck of the side fender, this has also led to some significant changes to the overall look of the bodywork, as the team explores how it can extract more performance from this stream. Auto generation.

While designers may have previously used planks and side leg rails to help recalibrate the airflow path, they no longer have these aerodynamic tools at their disposal.

This is significant in regards to the wake generated by the tires, as the front wings have also been simplified, reducing the amount of them used as a means of disabling and altering the alert.

In light of this, Haas submitted a revised diveplane design for the VF-22 at the British Grand Prix, although it failed to race up to this point.

This may indicate that it did not deliver the expected increase in performance on the wishbone style design without the accompanying new package (blue arrow).

The shape of the lateral hull has changed, the height of the shoulder has changed the overall geometry of the hull body (green highlight).

What can also be observed is how the side profile has changed as well, which is not only shown by the shape of the Haas livery, since the curvature is less severe, but is also visibly wider at the base (see front-right comparison and yellow highlight).

No longer having the aerodynamic tools listed above at their disposal, Haas is using a more aggressive approach in 2022, as they are forced to use the bodywork as a means of disabling, adjusting and recalibrating the tire track so as not to compromise performance.

Changes to the sidepods should help drive wake ups from the front tires away from the vehicle and also improve relationships further downstream, not only in terms of inwash required to improve flow into the coke bottle area, but also how airflow is being pushed. across the face of the rear frame.

Flow in the Coke bottle area will also benefit from changes the team made to the rear suspension, with the team reviewing the aerodynamics that wrap around the various components.

Another result of the side reviews, the team abandoned the central cooling arrangement on the bonnet spine that raised the shark’s fin away from the bodywork (red arrow).

Meanwhile, while the changes to the sidepod are pretty obvious, there’s a lot going on with the VF-22 flooring as well, as the team looks to gather more performance from an area of ​​the car where the designers have a lot of freedom.

In that respect, there are changes to the fencing at the front of the floor and at the edge, an area where all of its competitors have already made changes to improve flow conditions and improve ride sensitivity, while there are also undoubtedly changes made to the very lower floor.
