The 2015 Fiat 500 isn't as miserly as some of the other small cars on the road, but it's still more efficient than most vehicles on sale in the U.S. today.
If you go for the 500 Abarth, you gain power at the cost of fuel-efficiency, which still ranks well: it rates 28/34 mpg with the manual transmission.
The most efficient model is the base 500 equipped with the five-speed manual transmission, earning an EPA-estimated 31 mpg city and 40 highway. The optional six-speed automatic drops those figures to 27 mpg and 34 mpg, respectively.
Those are good figures, for the most part; but considering that mid-size hybrid sedans are beating this pint-sized mini at the pump, it's clear that there are some tradeoffs involved in keeping the price low and the driving attitude vivacious.
Electric 500e models can go 87 miles on a charge of the 24-kWh battery pack, and they're rated 116 MPGe (miles per gallon equivalent), overall.
