You want the sleekest look and the lowest price. The K4 sedan is the value entry point and the one most buyers pick.
You want more cargo flexibility from the wide rear liftgate and folding seats, for a small step up in price over the matching sedan trim.
The K4 is the smaller, lower-priced compact; the K5 is the larger midsize sedan with more room, more power including a 290-horsepower GT, and available all-wheel drive. Pick the K4 for value and efficiency, or step up to the K5 if you want more space and performance. We can put them side by side.
