The reliability of cars is not a criterion that applies to a certain type of vehicle or to certain brands, but represents the ability to be used in certain difficult conditions, such as in urban jam or on unpaved roads in rural areas. Thus, it cannot be said that one brand produces reliable cars and another does not, but it is the buyer’s duty to consider the conditions under which he will use the car and the purpose for which it is made, to determine whether it is or not suitable for his needs.

Among the most popular criteria considered when someone wants to buy a car are the engines and their size.


1. Classification of reliable vehicles by engine

Depending on the conditions under which a driver uses a vehicle, there are reliable and unreliable engines.

However, these rules do not necessarily apply to a particular type of engine, but must take into account an entire context.

Both diesel and petrol engines can be reliable or not, if certain essential aspects are taken into account, such as consumption, weather conditions, power or maintenance mode.

1.1 Reliable diesel engines

When it comes to longevity, low fuel consumption or noise pollution, there are some highly reliable diesel engines on the Car Market. For example, the Renault K-Type 1.5 dCi engine has been in the top of best-recognized engines for many years, while the VW 1.9 TDI PD engine is highly valued for its low fuel consumption favored by the injection system. These are some of the criteria that can determine whether  a diesel engine is reliable or not.

1.2 Reliable petrol engines

Unlike diesel, those that do not require large investments in maintenance can be classified as reliable petrol engines. Petrol engines also come with low carbon dioxide emissions, which means a lower environmental tax, especially in European Union countries.

The reliability of petrol engines can be seen, especially in the case of sports cars, because they are much lighter than diesel ones.

2. Classification of reliable cars by dimensions

Depending on the purpose for which a driver uses a car, its dimensions are essential. Here, other factors come forward, such as the age or hobbies of the owner, because a car can be reliable if it gives the driver what he wants and needs.

Both small and large cars can be used in comfort and safety. However, the priority issues for each driver must be taken into account.

2.1. Large reliable machines

In general, large cars are suitable for families and for traveling on difficult terrains, such as in the mountains.

In this case, car reliability occurs when a car can support a significant weight due to the storage of bulky luggage and transport of family members or when the lower part of the vehicle is at a height quite high from the surface on which it travels, avoiding any potential impact.

Thus, SUV cars can be reliable cars because they provide stability.

2.2 Reliable small cars

Small cars, such as the Convertible, are recommended for those who prefer sports models. They are advantageous because they are easy to handle, lightweight, to facilitate control.

There is no car ranking for reliability, because each driver has his own needs. For this reason, the car market is extremely developed to cover these diverse requirements. A reliable car is the one that meets as many specific needs of the driver as possible.

3. Frequently asked questions and answers about reliable cars

Are reliable cars cheap?

The financial investment that is made for a car is a criteria to establish the reliability, but it is not a rule that a cheap one has this characteristic. If the reason why it is cheap is excessive wear and improper maintenance, then the car is not reliable, even if it is cheap.

Are there reliable used cars?

And  used cars  , as well as those or purchased through  leasing, can be reliable as long as they are properly maintained and can provide a level of safety and comfort similar to that of a new car.

What does the reliability of a car depend on?

The reliability of a car depends on the parts, the maintenance and the manufacturing process.
