World's most reliable diesel cars

Recently, sales of cars with diesel engines have been declining.

Many manufacturers are dropping them from their ranges because they are not environmentally friendly. No one denies that diesel engines pollute the environment, but modern models are much cleaner than their predecessors and are equipped with all sorts of technical innovations to reduce the damage caused by exhaust emissions.

Diesel continues to play an important role in the European car market. Buyers with a focus on large vehicles and long distances are consciously choosing diesel engines, mainly because of the savings on increasingly expensive fuel. In addition, diesels are renowned for their durability and ability to develop high torque at low revs. They are often the choice of drivers who value reliability and efficiency.

If you're looking for a diesel car that will last you a long time and won't let you down in the toughest conditions, then this blog is for you. Today we take a look at the most reliable diesels, highlighting the key models that have won the trust of drivers and experts around the world in 2024.

Advantages of diesel cars

The main advantages of diesel cars are as follows

1. Economical fuel consumption. If you travel a lot, buying a diesel car is the right choice.
2. High traction. Diesel engines have high torque. This makes it possible to transport heavy loads and drive off-road.
3. Durability. It should be noted that the quality of diesel engine assembly has improved significantly in recent years.
4. Precision in the manufacture of assemblies and parts, new materials ensure the durability and reliability of diesel engines.
5. Safety. Diesel fuel is less flammable, so there is no risk of spontaneous combustion under the bonnet.
6. Maintenance savings. Although the cost of servicing a diesel car may be higher in the short term, the longevity of the engine and fewer visits to service centres often offset these costs. Diesel engines are less prone to wear and tear due to lower engine speeds.

Disadvantages of diesel cars

Despite their many advantages, diesel cars also have their disadvantages, especially with current trends in the automotive industry. The main ones are

1. High price. Diesel cars tend to cost more than their petrol counterparts. The price difference can be particularly noticeable when buying a new car, as diesel engines are more complex to manufacture and require more durable materials.
2. Noise and vibration. Although modern diesel engines have become much quieter, they can still be noisier and cause more vibration than petrol engines.
3. Negative environmental impact. Diesel engines are more fuel efficient, but they produce more nitrogen oxides (NOx) and particulate matter, which can be harmful to the environment and human health.
4. Bans and restrictions. Some countries impose additional taxes on the ownership of diesel cars. In addition, there could be a total ban on the sale of new diesel cars in Europe by 2030.
