The sedan is nearly two feet longer than the hatchbacks, while its wheelbase is about three inches longer. However, seemingly little of that goes to back-seat space; the back seats in the sedan only seem marginally more spacious. The Yaris Liftback models ride on a very short, 96.9-inch wheelbase and is one of the shortest new vehicles, at about 150 inches long, it can get pitchy or bouncy on certain types of roads. It's ideal as a commuter that can fit into the tightest parking spots, yet handle longer trips when the need arises.
Getting more intimate with the Yaris, you'll notice an interior that's obviously been affected by cost-cutting. While the instrument panel looks quite good from a few paces away, it's actually made of hard, easily scratched plastics, and the central gauge cluster is a novelty that few will find more intuitive or helpful. Front seats are rather small and skimpy, while the backseat on the Liftback is tough to get into but decent for space; kids should be just fine back there. The sedan looks like it might be roomier for back-seat occupants, but it's really not; it does, however, have a surprisingly spacious trunk.
The Yaris is better for road noise than other cars in this class, possibly due to the softer suspension calibration, but automatic models especially can feel somewhat boomy at higher speeds.
