Are both cars in an F1 team identical?

The two cars in a team are essentially identical, differing only in a few details, and they will be customized in different ways depending on the drivers, while the sporting and technical rules do not impose any specific requirements on the teams.

Single-seaters must comply with strict rules regarding weight, materials, and engines. Over time, new regulations have continually reshaped the way F1 teams design their cars, but there is still no requirement for each driver to have a chassis specially designed for them. Budget constraints In practice, teams operate within strict limits in terms of money, time, and personnel. It is simply not possible to build two cars entirely tailored to their drivers. They therefore opt for the technical solution they consider most competitive and develop both cars to the same specifications. It is only after the cars leave the factory that the drivers and their teams of mechanics make individual adjustments. The driver: the real source of variation between cars The cars are therefore not identical in use. They are identical at the start, but are then adjusted according to each driver's preferences.

Steering wheel – Each driver has a distinct style, which is why the cockpit layout is customized. The layout of the buttons and paddles on the steering wheel can vary; for example, Robert Kubica, after a hand injury, only uses the paddles on one side, while Jacques Villeneuve once had a clutch mounted on his steering wheel, a configuration that his teammates did not share.

Driver size – Seats are molded to the driver's body shape, which affects the reach and positioning of the pedals. Weight – Drivers vary in weight, and with improved safety features and the use of wider tires, cars have become heavier overall. Although the minimum weight of cars has increased, many teams remain above this threshold, meaning that a lighter driver can offer a performance advantage. Conversely, if the combined weight of the car and driver is below the minimum, ballast is added, which can improve stability and handling.

Cameras – The location of broadcast cameras complies with FIA rules, but teams may be equipped with additional equipment at the discretion of the FIA, which sometimes adds weight to capture new angles, such as shots from the helmet or from the bottom of the cockpit. Unintentionally uneven chassis Both cars are designed to be as similar as possible so that each driver has the same chance of scoring points. When both drivers are neck and neck, the team maximizes its points tally. However, some seasons have seen a significant gap between teammates, costing teams valuable points. Drivers who feel held back have complained about unequal power, as did Sebastian Vettel at Ferrari in 2020, finishing 13th with 33 points while Charles Leclerc took 8th place with 98 points.

Innovations for only one of the two drivers As teammates also compete against each other on the track, teams often prioritize the driver leading the championship when testing a new component. Introducing an update to the leading driver's car can widen the performance gap, giving that chassis a recurring advantage over the second driver throughout the season.
