The regular-length Savana rides a 135-inch wheelbase and measures 218.8 inches long, and extended-length models have a 155-inch wheelbase and stretch to 238.8 inches overall. These vans are considerably taller than minivans, ranging from 79.4 to 83.9 inches above the ground. With the seats removed, cargo volume is 267.3 cubic feet in the regular-length van or 316.8 cubic feet in the full-length model.

Two swing-out passenger-side doors can be replaced by a single sliding door, if desired. At the rear, two doors open a full 180 degrees to ease loading. The new SLT luxury van gets some distinctive exterior additions, as well as a fancier interior. Locks have been improved for 200l.
