Why Are F1 Cars Painted And Not Wrapped?
You may be wondering why F1 cars are painted rather than being wrapped, as wrapping takes less time, is cheaper, requires fewer people, and is easier to apply than paint.
The truth of the matter is that there are many reasons why F1 racing teams use paint for their cars rather than wraps, but the chief among these is the fact that the cars are so intricate that wrapping a formula 1 car is far more complicated than painting it.
The parts of a Formula 1 car that are painted are highly specialized components. They are designed to provide the best airflow and aerodynamics possible for the car.
Having a light coat of paint keeps the overall weight of the car down. F1 cars have on average only about 1.5kg (3.3lb) of paint applied to them, in contrast to the 25 – 30kg (55 – 66lb) of paint that is applied to commercial cars.
Aerodynamics – If the paint on the F1 car is not applied correctly, and if it is applied in layers that are too thick, it can negatively affect the aerodynamics of the car as it moves through the air.
F1 cars are made from carbon fiber materials and metal. These two materials must be joined together in places, which is very tricky to do, and often leaves gaps or small bumps, protrusions, or imperfections on the surface of the car.
Using fillers and paints, the painting crew must correct these imperfections and fill in the gaps to make the car as perfect as possible.
Paint applied in the right way in the right location on the car can significantly improve the lines and smoothness of the body of the car, which improves overall performance.
