There are many European cars that can be considered very fuel efficient. However, have you ever tried to put them on a list and finding out how efficient they really are? If you follow us after the jump, you will find that list, which shows Europe's 15 most fuel-efficient vehicles.
Interestingly, the list doesn't include just city cars, either. On it, you'll find subcompacts as well as compacts. Unsurprisingly, the truth is that you'll find that most of them are diesels which, thanks to the upcoming Euro V rules, now include DPF (diesel particulate filters) as standard. Perhaps even more unsurprisingly, the Smart CDI came out on top.
