The small 500 goes from pipsqueak to renegade as the speedster Abarth, the heart of which is a boisterous 160-hp turbocharged four-chamber. A five-speed manual is standard, while a six-speed programmed is discretionary. The fumes note is addictive, and on account of a pummeled suspension, the Abarth’s taking care of is as feisty as its styling. There is a roadster or sliding-canvas delicate top, however in outdoors frame, it can get somewhat expensive. Still, the Abarth is a unique auto with a huge amount of allure.
