Top 10: Most economical diesel cars

Although a large percentage of the population opts for petrol powered cars, not to mention the increasing number of people who are turning their attention to electric vehicles and hybrids, diesel powered cars still command a large portion of the market.

There's a fine reason for this; they offer near unparalleled levels of fuel economy while emitting incredibly low emissions. Although legislation is coming in against diesel, this is only on much older diesels that don't meet modern emissions standards.

Diesel cars universally offer excellent fuel economy, even the ones with large engines. So, which models actually offer the best possible fuel economy? Here's what we found.


Kia Ceed 1.6 CRDi (Official fuel economy - 72.4mpg)

Those South Koreans have certainly taken the European car market by the scruff of the neck in recent years. This is partly thanks to the reasonable cost of their vehicles, that also happen to boast good looks and a more than decent driving experience.

The 1.6-litre turbocharged diesel engine available isn't anything revolutionary, but with the ability to return 72.4mpg on a combined cycle while producing a lowly 102g/km CO2, it doesn't look like it needs to be. It looks great, drives well and is incredibly fuel efficient, count us in!

Vauxhall Corsa 1.3 CDTI (Official fuel economy - 78.5mpg)

The 1.3-litre turbocharged diesel engine isn't the pokiest engine in the world, but when it returns a combined mpg of 78.5mpg, we couldn't care less! In fact, settle down for a long journey on the motorway and you'll see a staggering 88mpg from the little Corsa.

Mercedes-Benz A Class A180d (Official fuel economy - 80.7mpg)

Citroen/DS 3 1.6 BlueHDI (Official fuel economy - 78.5mpg)

Although DS have now separated themselves from the Citroen brand, the DS3 still boasts the same architecture. This is no bad thing, because it has frequently been celebrated for its refreshing take on driving engagement. It's plenty of fun without being too serious, harder to achieve than you may think.

The 1.6-litre diesel engine is a magnificent little unit and manages to produce a pretty substantial 78.5mpg on a combined cycle. The 3 clearly represents excellent value for money then, while boasting plenty of character to make daily driving all the better.
