10 BIGGEST misconceptions about diesel cars, busted!

The diesel vs petrol debate never ends. While a lot of people swear by petrol, many have shifted to diesel. However, there are many misconceptions about diesel cars. We bring you the top ten.

Need to be driven daily, else maintenance becomes high

This is by far the most common misconception. Modern diesel cars do not need constant attention. You can use it when you need to. Else you can park it safely without worrying about the parts becoming jammed.

Earlier, it was a fact that diesel cars needed to be run more often than petrol vehicles. In modern vehicles, however, this is not true as technology has made diesel similar to petrol in terms of usability.

Diesel mean significant money savings


At one point in time, diesel vehicles enjoyed the low price of fuel. At present, however, the price difference between petrol and diesel is not more than Rs. 15 per litre across India. The lower difference between the fuel prices means that it takes longer for diesel cars to break even with the cost difference with petrol cars because of higher initial costs. With the current fuel prices, it may take many years to cover the difference in price between the petrol and diesel variants of a vehicle. Once that difference is covered, diesel vehicles have a nominal advantage of operation against petrol vehicles.

Not fun to drive


OK, petrol engines may rev higher and may have a “feel good” factor. However, in real terms, the low-end torque of diesel engines is much more fun to use on a day-to-day basis. All diesel engines have higher torque than petrol engines. To make it easier to understand, torque is the force that puts things in motion. Higher the torque, quicker the parts will set in motion and faster you will move. Petrol engines have lower torque, concentrated in higher RPMs, giving them a big disadvantage.

Spark plugs are essential parts of diesel engines

Right? No! Diesel engines are much more sophisticated than the petrol engines. Diesel engines do not depend on the spark plug igniting fuel in the combustion chamber. Instead, they use higher compression. There are no spark plugs in a diesel engine.

Affordability and diesel automatics do not go together

There used to be a time when diesel automatics were not available in the affordable car segment. At present, many cheaper diesel automatics have come to the market. AMT technology has made this possible. There are many diesel automatic options available in the sub-10 lakh segment in the market, including the Maruti Ignis and Dzire Diesel AMTs.
