Talk to different people and you may very well get different definitions for coupe and sedan. While some definitions center on certain subjective styling elements, among modern cars, the difference has mostly been clear-cut: Coupes have two doors, a trunk and a fixed roof, while sedans have four doors, a trunk and a fixed roof. And with their greater focus on sporty design, coupes typically aren’t as good as their sedan siblings at carrying people and cargo.
However, the line between what’s a coupe and what’s a sedan has been getting blurrier each year as automakers — particularly luxury ones — launch new models that test these definitions.
