Are Diesel Cars Still Worth The Extra Cost?

There was a time where diesel cars were the popular choice amongst motorists, thanks to the low road tax and superior fuel economy offered. This meant frugal motorists bought more diesel cars than petrol because of the savings they made in their monthly budgets.

However, times change with the roll of a dice and diesel-powered cars are no longer considered good investments. They no longer receive the following benefits:

  • No longer low road tax: only electric cars are free of road tax, whilst all cars that produce emissions are charged a fixed amount after the first year. This means that diesel cars are as expensive to tax as petrol cars.
  • rn

  • The residual value of diesel cars once meant that these cars held their value longer than petrol cars. However, in recent years that difference has begun to level out with the decrease in residual values.

  • Manufacturers charge premium prices for the same diesel model as a petrol car. However, thanks to recent developments, petrol cars have become more economical and cleaner to drive, which means diesel cars no longer justify those higher prices.

  • There is the threat of legislation regarding diesel engine because of the failed emissions test scandal regarding diesel engine and the concern over air pollution. Whilst diesel cars do not produce as many CO2 emissions as petrol cars, they do produce more harmful particulates that contribute to the rising problem of air pollution in our major cities.

Contributing to air pollution

Diesel engines produce nitrogen oxides, which are one of the main causes of air pollution. This has resulted in the introduction of additional charges for the oldest, highest-polluting diesel cars when driven in Low-Emission Zones at peak times.

However, developments have been made on the newer models of diesel cars. In January 2011, we saw the launch of the Euro 5 standard engine. This meant that car manufacturers ensured their engines complied with the limit of 0.18g/km of NOx, which resulted in the cars being fitted with diesel particulate filters (DPFs). DPFs captured 99% of all particulate matters before it leaves the exhaust, thereby reducing the amount of harmful pollution entering the air.

With the launch of Euro 6, which is September 2015 onwards, diesel cars cannot produce more than 0.08g/km of NOx. This means that any diesel car manufactured after that date are the cleanest diesel cars in history. Alongside the DPFs, these new engines have systems that convert the NOx produced by the engine into largely nitrogen and water, thereby removing the harmful particulates.
