The Savana is available in various cargo and passenger van models. This full-size hauler is a favorite of conversion van companies and contractors, who appreciate its huge cargo capacity and wide variety of powertrains. Choices include a 4.3L V-6, and 4.8L, 5.3L, and 6.0L gasoline V-8 engines mated to a 4-speed automatic. The 6.6L V-8 Duramax® diesel (250-bhp/460 lb.-ft) equipped Savana can tow up to 10,000 lbs. An extended wheelbase model has extra cargo capacity or can accommodate up to 15 people.
