Cheapest Euro 6 diesel cars

Get an emission zone-exempt car and avoid ULEZ charges: these are the cheapest Euro 6 diesel cars

If you're considering a diesel car, then it makes a lot of sense to choose one that meets the latest emissions standards, known as Euro 6.

It will mean that you won't need to worry about London's new ultra low emission zone (ULEZ), if you drive into the capital: owners of non-Euro 6-compliant diesels will be charged up to £12.50 a day to drive in the city centre, and the zone will expand to cover most of the capital in two years.

Even if you avoid driving in London like the plague, several cities are considering similar clean air zones, which will also target older diesel models: Birmingham will set one up at the beginning of next year.

Fortunately, it's easy to find a Euro 6 car and it needn't be expensive. Prices for diesel cars start at £5,300 or from £83 per month on finance. Every car sold new since September 2015 has had to meet the emissions standard, so any vehicle that's three years old or less should comply.

In addition, several cars met the Euro 6 regulations early and we've listed them in a separate Euro 6 diesel cars article. Alternatively, you could opt for a petrol car. As long as it is less than 12 years old, it should be exempt from charges under current plans. Whatever car you're buying, it's always wise to check with the seller that the vehicle does meet the Euro 6 standard.

Cheapest used Euro 6 diesel cars 



1. Dacia Sandero

Latest Euro 6 Dacia Sandero diesel deals from £5,446
Finance from £95 per month

With a reputation as the UK’s cheapest new car, the Sandero was always going to be a Euro 6 bargain. A diesel Sandero is more expensive than a petrol-powered one but if your mileage is higher than average or you regularly travel with a full load, it’s a price worth paying.

In any case, less than £110 per month for a two-year-old diesel Sandero in decently equipped Laureate trim looks like value for money. The Renault-sourced diesel engine is smooth, reasonably powerful and capable of up to 80mpg, although 60mpg is more likely in the real world.

2. Citroen C3

Latest Euro 6 Citroen C3 diesel deals from £7,199
Finance from £115 per month

Prices for a 2015, Euro 6-compliant Citroen C3 regularly start at under £100 per month on finance, and it's often the cheapest car that BuyaCar sells, with prices often lower than the second-hand Dacia Sanderos on the site.

At this price, you're not looking at the modern, chunky Citroen C3, with its swept-back grille and thin LED lights, but the earlier version of the car, which looks less distinctive, but still offers a good level of comfort by soaking up the impact of potholes effectively. Space in the back is roughly equivalent to a modern Ford Fiesta, but there's nowhere near as much technology, and the car leans far more in corners - even at fairly slow speeds. Opt for edition or Platinum models, which have more equipment than basic VT cars.



3. Fiat 500

Latest Euro 6 Fiat 500 diesel deals Limited stock

The little Fiat is a city car at heart, at its best with the 1.2 or 0.9 TwinAir petrol engines. However, if you want to stretch its legs out of the city on longer trips, then the 1.3 diesel engine is the better choice.

It’s no ball of fire but it will cruise quietly and comfortably all day long. You can expect real-world fuel economy of around 60mpg, which is reasonable, if some way off the official figure of 83mpg. It's no longer being produced, so there aren't many around to choose from and prices can vary considerably.

4. Hyundai i20

Latest Euro 6 Hyundai i20 diesel deals Limited stock

Not a great number of Hyundai i20 buyers choose the diesel option but, at the time of writing, there was a reasonable choice of models at a low price.

It's not a bad choice for the car, as it delivers power without needing to be revved, so feels reasonably fast - even though it does take a slow 16 seconds to accelerate from 0-62mph. It is noisy as you gather speed, but settles down at steady speeds, where it's also efficient. Expect around 55mpg in real-world driving.

5. Renault Clio

Renault owns Dacia, and so it uses the same engine as the Dacia Sandero at the top of the list, wrapping it in a more stylish and contemporary design. It’s more expensive but you can see where your money's gone, thanks to an interior that feels more upmarket than the Sandero, even if it doesn't match more modern alternatives, such as the VW Polo and Seat Ibiza.

The performance of the Clio and Sandero is largely the same, with official fuel economy of 85mpg, which is more more 55mpg in normal driving.

6. Nissan Note

Nissan is another company that's linked to Dacia and Renault, so the Note uses the same diesel engine you'll find elsewhere on this page in the Sandero and Clio. It’s noisier in the Nissan than it is in the other two cars but just as strong when accelerating.

In fact, more than the other cars, the engine is perfect for the Note which is an impressively roomy car easily capable of carrying five adults in comfort. The Note is no longer made, but there is usually a good choice of relatively recent models available.

7. Skoda Fabia

This is not the most smoothest or quietest small diesel engine on the market but it is pleasingly powerful from very low revs, so there’s rarely any need to strain it.

You can expect fuel economy of around 53mpg in real-world driving, making the engine a good partner for the value-for-money Fabia which, in SE trim, nevertheless features a digital radio, parking sensors, alloy wheels and body coloured exterior trims.

8. Vauxhall Astra

Latest Euro 6 Vauxhall Astra diesel deals from £6,099
Finance from £110 per month

Vauxhall put a 1.6-litre Euro 6-compliant diesel engine into the Astra from April 2014, which today gives buyers the choice from five years of production. Prices for early cars are now close to £6,000, which makes it one of the cheapest Euro 6 diesel models available, and the biggest car in this list, which is ideal if you're looking for affordable family transport.

The lowest-priced cars are from the previous-generation (pictured), which is a solid performer, offering comfort, quietness and stability in corners. Newer, current-version 2017 models start from £8,780Vauxhall Astra buying guide
