* Coupe: A Chevelle coupe is a two-door car with a shorter, sportier profile. It typically seats only two people in the front, although some models had a small back seat suitable for children or occasional use. It has a sleeker, more streamlined look compared to the sedan.
* Sedan: A Chevelle sedan is a four-door car with a longer wheelbase and more passenger space. It offers seating for at least four, if not six passengers (depending on the model). The sedan has a more upright, boxier design compared to the coupe's sloping roofline.
In essence, the coupe is the sportier, smaller, two-door option, while the sedan is the more practical, larger, four-door family car. Both shared the same basic mechanicals but differed substantially in their body style and passenger capacity.
