Secret F1 data & dimensions
Red Bull has the shortest car
Wheelbases and angles of attack of the cars are among the most secret data of the cars. The teams spy on each other and use photos to calculate the most important dimensions. A team has provided auto motor und sport with the data.
It used to be normality. All Formula 1 teams announced the overall length, width, height, wheelbase, front and rear lane when introducing their new cars. In addition the weight. The angle of the car 30 years ago played no major role. So you did not care about it.
Today, the teams say only as much as they have to. The total width of two meters is the same for everyone, because everyone goes to the maximum of the regulations. The weight of 743 kilograms including driver is also identical, because all are at the weight limit. The rest of the dimensions remain secret.
Actually ridiculous, because the teams know each other at the latest after the first week of testing exactly. The data is determined by photos. And so it works: All cars are photographed at slow speed in the pit entrance from the side. If possible in exactly the same place to reduce the error rate. The same thing happens from above.
Since the diameter of the wheels is known, all other dimensions are determined from the scans and then compared with their own data. The comparison of the measurement with the real data results in accuracy of the measurement.
In our case, the team in question has determined an accuracy of 0.5 percent for the wheelbases. At the angle of attack, the calculation is naturally higher at just under 5 percent. But that does not change the relationship. The longest measured car is also real the longest car. And the one with the largest angle of attack actually drives at the rear with the greatest ground clearance. The trend is always the same.
79 millimeters between Mercedes and Red Bull
So where are the 2019 cars? One thing can be said. The wheelbases are all awfully long. Too long. No car measures under 3.60 meters between the wheels. 2021 should change that. Then the wheelbase should be at a maximum of 3.40 meters. At the moment, Mercedes still has the longest wheelbase with 3,698 millimeters, closely followed by Sauber with 3,697 and Toro Rosso with 3,693 millimeters. With a wheelbase of 3,619, the Red Bull RB15 is the most compact car in the field.
That Red Bull and Toro Rosso and Ferrari and Haas have different wheelbase surprised a bit. Do not these teams work hand in hand with the design of the cars? Haas, for example, takes over Ferrari's suspensions 1: 1. "Nevertheless, our car can be longer or shorter because we have to build our own chassis. The height of the drivers can also make a difference in the chassis length, "explains Haas Operations Manager Ayo Komatsu.
At Red Bull there is a second explanation for the differences in the cars of the A- and B-Team. "We did not make the decision to increase synergy until after the summer. Since parts of the Toro Rosso were already developed, "explains sporting director Helmut Marko. The chassis is one of those parts that engineers have to commit early because of the long lead time.
Renault drives largest employment
While the wheelbases are all within a relatively narrow range of 79 millimeters, there are larger differences in the angle of attack in the field. The car with the lowest ground clearance in the rear is still the Mercedes W10 with measured 84 millimeters. The Renault RS19 is located at a height of 141.2 millimeters at the rear axle at the other end of the scale. This results in the case of Mercedes an angle of 1.16 degrees, at Renault 2.15 degrees.
However, our measurement comes from the first week of testing in Barcelona. In the second Mercedes has apparently increased the angle significantly. According to our information, by almost 20 millimeters. Prompt, the car was faster.
Allegedly, Mercedes wants to moderate this way moderately continue, with the engineers because of the length and the basic philosophy of the car certain limits are set. Ferrari lies with a ground clearance of 113.4 millimeters behind and a pitch of 1.64 degrees closer to Mercedes than to Renault.
Red Bull drives as the inventor of the salaried car behind with 131.1 millimeters of ground clearance. The subfloor is angled 1.93 degrees relative to the road. Renault, Racing Point and Toro Rosso have gone more extreme with their 2019 cars than the pioneer of this vehicle concept.
The strong angles of attack can often only be achieved with a trick that, according to experts, is on the verge of legality. Our team has also measured the so-called "Chin Height", ie the height of the skid of the subfloor above ground. From this it can be determined that certain floors at the front end must be bent slightly upwards. Otherwise, she would have permanent contact with the asphalt.
