Depending on their configurations, Savana passenger vans can carry eight, 12 or 15 occupants. Cargo vans seat only two people up front. The restyled interiors feature an upgraded climate-control system. Both Radio Data System (RDS) technology and GM’s OnStar communication system will be available. The use of an advanced Class II electrical system permits the addition of such features as battery run-down protection, delayed accessory power, lockout protection and an expanded number of driver alerts. Passengers also get an additional power outlet and more cupholders in the 2003 model.
