Thanks to their great fuel economy and impressive torque, diesel car sales in Australia have been strong in recent years.

To help you find a decent car, we've put together a list of the five best diesel cars in Australia. Whether you're looking for a diesel SUV, hatchback, or Sedan, we've got you covered.

But before that, let’s discuss whether a diesel car is really worth it. 

Should you really buy a diesel car?

There are many reasons why people all over the world love diesel cars. Let’s discuss some pros and cons of a diesel car to help you make an informed decision.


Some of the most notable advantages of a diesel car are:

  • Diesel cars offer excellent fuel economy and perform well for long stretches of drive, e.g., cross-country road trips or highway drives.
  • Diesel engines produce more torque than gasoline engines, which results in a powerful ride.
  • Diesel engines are built differently from gasoline engines and require minimal routine maintenance, which saves you money. You can also save money on repairs by comparing mechanics with DingGo and finding yourself the best deal.


You should be aware of the following disadvantages before buying a diesel car:

  • While diesel cars usually require minimal maintenance, they can be more expensive than petrol cars when they do.
  • Despite advanced technologies, diesel engines are not usually as quiet as petrol and electric engines. 
  • While diesel cars produce high torques, they don’t have much to offer in terms of horsepower. You can read about the difference between torque and horsepower here.


With that out of the way, let’s look at the 5 best diesel cars you’ll find in Australia.
