Fiat 500-cinquecento

Let's talk what is mighty about the Cinquecento first: stunningly styled modern take-off on a much loved original which was the Fiat Nuova 500 from 1957.
It is a car which identifies with the old and the young in one compact package without making either feel ashamed of getting in and using it in the urban European environ. Heck it would work wonders in crowded Indian streets just as well. It is a triumph of Fiat's engineering and design capabilities, using established hardware and floorpan to spin off an all-new, all-different product at ridiculously low development costs.
It is mega in its essence as a city car, great in today's socially conscious times where to have less is great. For a car so small (just 3546mm long and built on a short 2300mm wheelbase) it has impeccable manners and agility.
Mighty in its employment of the famous Fiat 1.3 Multijet diesel engine with killer fuel efficiency to set it apart from the rest.
