Which petrol car has the best MPG?

I am looking to purchase a 3-4 year old car. What is the best petrol vehicle that provides 55 miles to the gallon?

There are quite a few petrol cars in this bracket, but the best of the bunch is the Toyota Prius, which in our Real MPG figures is achieving an average of 65.2mpg - well over your target of 55mpg.

Strictly speaking however the Prius is a hybrid rather than purely petrol, so for a petrol-only alternative we would suggest something like the Suzuki Swift with the 1.0-litre Boosterjet engine, which is achieving an average of over 60mpg in our Real MPG figures.
