Dimensions

The typical sedan is tremendously heavier than the Kia Rio. Your wallet will hurt more every time you fill up the typical sedan than the Kia Rio because of its larger tank. The Rio and the typical sedan compete for the same parking spaces. The typical sedan's longer wheelbase will result in a smoother, more stable ride; on the flip side, the Kia Rio may give a sprier feel in daily traffic.
