The 2016 FIAT 500X competes in the hot new subcompact-crossover segment with models such as the Honda HR-V, Chevrolet Trax and Mazda CX-3. It’s on our list of Must Test Drive vehicles of 2016 because we were truly impressed with the 500X and because it changed our opinion of FIAT from a brand that makes an OK small car to one that could field a credible competitor in other segments, too. If you know FIAT from the tiny 500 or the subpar 500L, the 500X is nothing like those models. It’s roomy, offers more-than-adequate power, is as capable and efficient as rivals, and is reasonably priced. It may seem odd if you only associate FIAT with the tiny 500, but we don’t think you should buy a new subcompact crossover without test driving a 2016 FIAT 500X.
