Under the Hood
The Savana may be equipped with one of four engines. Light-duty, RWD G-Series vans have a 200-hp, 4.3-liter V-6 as the base engine. Three V-8s are available: a 270-hp 4.8-liter, a 285-hp 5.3-liter and a 300-hp Vortec 6000 (6.0-liter). Each engine mates with a four-speed-automatic transmission that incorporates a Tow/Haul mode. All engines have new air-filter and oil-life monitors.
