With its adorable styling you almost want to hug this latest Fiat. But the more time you spend with it, the more its appeal wanes, thanks to its stiff ride, noisy cabin, restricted visibility, annoying vibration when idling, and unsupportive seats. Styled like a burlier Fiat 500, the X is a sister vehicle to the Jeep Renegade, and it shares some of the same virtues and weaknesses. Both models offer two four-cylinder engines: the 160-hp, 1.4-liter turbo and a 180-hp, 2.4-liter. Both are mated to a nine-speed automatic that is neither smooth nor responsive. Fuel economy, at 23 mpg overall, is unimpressive for a vehicle this size. The interior has some flair, and a number of upscale features, such as heated seats, blind-spot warning, and lane-departure warning, are available.
