Two Hatchbacks with some similarities, but otherwise different in most aspects such as the horsepower, ground shadow size, fuel economy, height, and maximum occupancy. First of all, the 2016 Kia Forte Hatchback has a more powerful engine and gets 6 mpg less than the 2015 FIAT 500 Hatchback. Also, comparing the dimensions we see that the 2015 500 Hatchback is significantly smaller, although it's slightly taller than the 2016 Forte Hatchback. And finally, you'll seat one more passenger in the Forte Hatchback than in the 500 Hatchback. Among similarities are the body structure and starting price.
