| 2015 Chevrolet Trax Seat Room and Comfort: Cons | ||
| Year | Comment | |
| There's much more room inside the Trax than many people expect given its compact exterior. At 5-9, I could sit behind myself with a few inches of knee room to spare. But if the people in the front seats are taller than me, those in the back seat better be shorter. The Renegade and 500X have about the same amount of rear knee room as the Trax. They have a couple inches more shoulder room, though, so fitting three people in back is a little less of a squeeze. (It will still help if they enjoy physical contact with one another.) The Honda HR-V isn't wider, but does have a few more inches of rear legroom. On the other hand, the rear seats in the Nissan JUKE and MINI Countryman are tighter than that in the Trax. see full Chevrolet Trax review | ||
