America's best-selling minivans received their first major overhaul in 1991 since their debut seven years prior. The revamp included a restyled exterior, a new interior, and the addition of all-wheel-drive (AWD) models and optional antilock brakes. Later that year, Dodge added an optional driver-side airbag. Exterior dimensions were unchanged from the previous model, but the corners were rounded off and the glass area was increased. The Caravan, along with the nearly identical Plymouth Voyager, come in standard- and extended-length versions (called Grand). Also similar, the Chrysler Town & Country comes only in the long version. Seven-passenger seating (two front bucket seats, a 2-place middle bench, and a 3-person rear bench) was standard on all except the base model, which seated five.
