Every car sold in the U.S. except the Ford Crown Victoria and Lincoln Town Car has unibody construction. The Crown Vic and related Town Car are the only two passenger cars that have body-on-frame construction, and production of those two models is scheduled to end later this year. That leaves pickup trucks, some SUVs (Chevrolet Tahoe and Ford Expedition among them) and full-size vans as the only body-on-frame vehicles still available. Crossovers such as the Chevrolet Equinox and Traverse, Toyota RAV4 and Highlander, Honda CR-V and Subaru Forester are among the many unibody SUVs.
Unibody construction, in which the frame and body are formed as an integrated unit, saves weight compared with vehicles with a separate frame, a key factor in increasing fuel economy. Having a separate frame gives trucks, SUVs and vans greater payload and towing capacity compared with unibody vehicles.
