Features aerodynamics Haas VF-20February 6, 2020
The versions of cars that we see at the start of the Australian Grand Prix and even at the pre-season tests in Barcelona often differ from those that the teams present at presentations, especially if they are limited only to computer images of the new chassis.
Still, experienced experts, studying even such pictures, immediately pay attention to certain features, and the VF-20, presented by Haas F1 is no exception.
Strictly speaking, only the color scheme was presented today, in which these machines will be painted in 2020: the American team decided to return to the traditional Haas Automation company range. But compared to last season, the shape of a number of components, for example, rear-view mirrors, has also changed. Their fastenings and the shape of the hulls have become different, now they should more effectively direct the air flow blowing around the machine in the right direction.
But mirrors are just a small part of the new aerodynamic body kit. It can be seen that the front wing is completely redone, and the contours of its planes and the configuration of the end plates have noticeably changed.
Now the wing is pretty much reminiscent of a similar element of last year’s Ferrari cars. Haas engineers also revised approaches to side deflectors – the upper part of these parts has become clearly wider. The top air intake on the VF-20 is also similar in shape to the one we saw in 2019 on the SF90.
This resemblance to the machines created in Maranello is not exhaustive, which is not surprising, because Haas closely cooperates with Scuderia, acquiring literally everything from the Italian team that is allowed by the regulations. First of all, these are power plants, transmissions and suspension parts, which largely dictates the layout of the rear of the car.
Therefore, this VF-20 area is also largely copied from Ferrari, although some of the aerodynamic elements in Haas are developed independently, or rather, in partnership with the Italian company Dallara.
Last year’s Haas machine suffered from inefficiency of the rear of the chassis, in slow and medium-speed corners, the downforce in this area was significantly reduced, and this led to increased wear of the rubber. It is clear that the team is trying to solve problems that affected the speed of last year’s car, and they expect that the VF-20 will generate more downforce and make it much more stable.
Naturally, Haas tried to take into account last year’s lessons and create a chassis devoid of serious flaws. The question is different: did the experts get to the bottom of the root cause of those problems, fully understand everything and find the right solution. Most likely, we will not find the answer to it before the season begins.
