What Defines a Sedan
A sedan has a three-box body with a separate trunk accessed through its own lid. This design offers better cabin sound insulation than a hatchback or station wagon because the cargo area is physically separated. Classic sedans are divided into compact (e.g. Audi A3 Sedan), midsize (BMW 3 Series, Mercedes C-Class) and large (BMW 5 Series and 7 Series, Mercedes E-Class and S-Class). Most models are available with petrol, diesel, hybrid and plug-in hybrid powertrains, as well as front-wheel drive, rear-wheel drive or AWD.
