Cheapest Euro 6 diesel cars

Get an emission zone-exempt car early: these are the cheapest Euro 6 diesel cars

If you're thinking of buying a diesel car, then you would be wise to choose one that meets the latest emissions standard, known as Euro 6.

From next year, cities including London and Birmingham will start to bring clean air zones into force. Anyone driving a diesel car that isn't Euro 6-compliant will be charged up to £12.50 a day to drive in city centres. Over the coming years, 17 councils may introduce similar charges.

Fortunately, it's easy to find a Euro 6 car and it needn't be expensive. Prices for diesel cars start at £5,950 or from £94 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 compiled them in a separate Euro 6 diesel cars list. 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 £5,995
Finance from £101 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.

Even then, less then £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 £7,100
Finance from £106 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 secnd-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 offrs 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. Renault Clio

Latest Euro 6 Renault Clio diesel deals from £7,000
Finance from £117 per month

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.

5. Nissan Note

Latest Euro 6 Nissan Note diesel deals from £5,950
Finance from £94 per month

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.

6. Skoda Fabia

Latest Euro 6 Skoda Fabia diesel deals from £7,990
Finance from £123 per month

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 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.
