In general, they are better protected against car corrosion from the higher levels of the price list. For example, Mercedes-Benz galvanizes the entire body with a fairly thick layer. Audi, on the other hand, likes to use aluminum, which resists corrosion. Here we come across, for example, Audi A2, which, although it belonged to the lower segment, was practically entirely made of aluminum. However, it was more of an experiment without continuation, because the aluminum glued castle has its disadvantages.
Renault
A brand known for the fact that their cars are simply not eaten by corrosion. Why is it? If you take a closer look at these cars, you will find that they pay more attention to the details during development and production, which decide whether or not corrosion will have a chance. Renaults tend to have a very well-protected chassis and undercarriage, for example, they minimize so-called trap points, i.e. places where water tends to hold without draining. Furthermore, for example, critical places are well protected by a layer anti-corrosion plastic coating, which is of high quality and will really last for years. Surprisingly, the body is not completely galvanized, but only its critical parts, which are supposed to be exposed to the worst conditions. Nevertheless, Renaults resist rust perfectly.
Volvo
For the Nordic brand, it is somehow assumed that its cars should be corrosion-resistant. Yes, it’s true, and Volvo uses the same basis as most other manufacturers – a galvanized body. Apart from other usual steps like plastering and spraying the chassisthe car manufacturer protects itself from corrosion i aluminum parts chassis. As soon as something is made of aluminum, there is no risk of deep corrosion, the problem is that such parts are also more expensive than steel, which partly explains the higher price of Volvo cars.
Audi
Between 2007 and 2015, Audi experimented a bit and reduced the zinc layer applied to the body from 5-10 microns to 3-8 microns. Apparently the customers felt it, so it followed return to a stronger layer galvanizing 5-12 microns. Together with aluminum, which the automaker really likes, and quality treatment of the typical places where corrosion starts, galvanizing forms an excellent protection against corrosion.
Corrosion protection for a specific car
The basis of anti-corrosion protection is the galvanization of the body and, above all, its strength. In this direction, the website can be a very decent help Galvanicarwhich brings together information about anti-corrosion protection of that model. After entering the car manufacturer, model and year of manufacture, you will find out which parts and how they were protected by galvanizing. Alternatively, you can look for other details, such as the use of aluminum, laser welding and the like. As a guide, this information can be good, unfortunately not even complete galvanizing on the first generation Honda Jazz did not help much and the cars literally rusted before our eyes.
