Most Economical Sedans

Below are the top 10 most economical sedans based on combined fuel economy.

The tiny diesel Fiat 500 tops the list but remarkably there are other very fuel efficient diesels that are not far behind yet are a lot bigger than the 500. The stand out of these is the C4 which is only 0.3 litres behind the 500 in combined consumption but would make a very practical family car because of its size, unlike the 500.

If you want hybrid technology currently the Honda Civic is the only hybrid sedan available.

Fiat 500

The most economical sedan is the good looking trendy little Fiat 500.

It has a tiny 1.3 litre turbo diesel engine weighing only 130kg. The result is a very lightweight, very efficient car, and despite the 55 kW engine the car still feels quite nippy around town.

The 500 also emits only 111g/km of CO2 and has a particulate filter to reduce other pollutants.

One negative of the Fiat 500 in general, not just the diesel model, has been its road handling. Its been described as bouncy and vague, especially compared to one of its greatest rivals, the road hugging Mini.
