15 Cars that NEVER Rust (100% Galvanised)
All metals have a tendency to corrode. Ferrous metals are no different. Almost all car bodies are made up of these ferrous metals.
Moisture is a killer of them As soon as the car body comes in contact with moisture, it tends to get corroded. By corrosion, we mean the process of formation of iron oxides (rust) via oxidation reaction due to the presence of moisture on the metal surface.
In this article, we’ll cover the top 15 cars that don’t rust and 15 cars you should avoid buying due to their rusting problem.
How Galvanizing Protects Against Rusting?
There are a number of ways to make vehicles anti-corrosion and galvanizing is one of them. Galvanizing is the process in which metallic components are hot-dipped into molten zinc metal. In some cases, the zinc coating is applied by using the electroplating method as well. This layer of zinc inhibits the corrosion process. Due to which paint layers stay intact for a longer period.
Following are the 15 cars that never rust. They have shown excellent resistance against corrosion.
1. Renault Clio
Renault cars are immune to rusting in general. Clio is a prime example of this. The car has been galvanized 100%. In addition to that, it has plastic wings with no chances of corrosion. According to a survey conducted by Swedish magazine, Renault Clio was the only car with a 0% corrosion percentage. No other car performed that well on the survey.

10. Porsche 911
How we could have possibly missed Porsche 911 on this list? Porsche is the pioneer of using galvanized steel in the construction of cars. Porsche 911 was the first car in 1976 that was built on fully galvanized body panels. This enabled the company to give a 6-year rust protection warranty to its buyers. This warranty was further extended to 7 and then 8 years for upcoming models.
11. Hyundai Accent
Japanese cars don’t have a great reputation for being rust-free. Since no salt is used to melt ice on roads in Japan. So, manufacturers don’t have to worry about the rusting issue. But Japan has a huge global market. In order to cater to these markets, the Japanese auto industry has raised its coating standard. Now, Hyundai is using fully galvanized steel body panels to make its cars. Hyundai Accent is one prime example of it. You can purchase this car without any fear of losing it to rust.
12. Kia Forte

So that even if the paint starts peeling off at a certain place, you have enough time to get it repaired before the body starts rusting.
Why Do Some Cars Rust and Some Don’t?
Some cars are more resistant to rust as compared to other due to the zinc coating on their exterior. Zinc coated or galvanized materials prohibits the oxidation reaction on car surface which doesn’t lead to products like ferrous oxide.
Another reason is the use of superior steel material in some cars. These steels have an in-built capacity to resist rust due to additives like zinc and magnesium.
Rusting of a car is primarily dependent upon the quality of its coating. If the exterior of a car has been coated with zinc of appropriate thickness then it won’t peel off or corrode quickly. Older cars are at higher risk of rusting because their zinc coating wears thin over the course of time.
It is true that mild steel contains less than 1% of carbon and primarily it is iron. But steel isn’t only carbon and iron. It has certain amounts of additives like manganese, silicon, phosphorous, and Sulphur. The quantity of these additives decides the quality and performance of steel. For example, an increase in the amount of manganese can have a positive impact on corrosion resistance. Hence, if such suitable alloys of steel are used in the construction of cars they have fewer chances of rusting.
Which Cars to Avoid if You Don’t Want to Have Rust Problems?
Though it isn’t fair to generalize but you should avoid American, Japanese, and French cars if you don’t want to have rust problems. These countries especially Japan have produced cars with superior coatings as well. Still, if you live in an area prone to corrosion or where salt is used to melt ice on roads, then you should avoid these cars.
In addition to this general advice, you must steer clear of any of the following models if you don’t want to have rust problems. These cars are rust buckets and corrode very rapidly. These cars include:
- Mazda 3
- Pontiac Wave
