There are four different engines offered in the Savana vans. Most models are equipped with either a 4.3L V6 that makes 275 horsepower and 298 lb-ft of torque or a 6L V8 making 341 horsepower and 373 lb-ft. Separately, there's a flex-fuel version of the 6L that can run on a fuel mix of 85 percent ethanol. And for those needing the most hauling power in a gasoline engine, the 2.8L turbo charged 4-cylinder makes 181 horsepower and 369 lb-ft. Across the entire lineup, the Savana comes with a 31-gallon fuel tank. All 2500 and 3500 models come with a heavy-duty 6-speed or an 8-speed automatic transmission.
The Savana has true body-on-frame truck construction, with a ladder-type frame plus tubular cross members for better torsional stiffness and tapered frame rails for safety. It rides on an independent front suspension and rear leaf-spring suspension, with a stabilizer bar in front and a locking rear differential available on all models. Steering is via a recirculating-ball gear. In all Savana vans, four-wheel anti-lock disc brakes with dynamic rear proportioning adapt to loads and provide secure stops. GM's StabiliTrak electronic stability control also helps provide safety and prevent skids in sudden maneuvers, while all models include driver and front passenger air bags.
Both of the Savana 2500 and 3500 grades are offered in LS and LT models. Standard equipment includes air conditioning, auxiliary power outlets, a driver information center and an AM/FM radio. LT models step up to rear air conditioning, a rear auxiliary heater, remote keyless entry and power windows. Options include 6-way power-adjustable driver and passenger seats, remote start, a leather-wrapped steering wheel with audio controls and an improved audio system with CD and MP3 capability and a USB port. In all models there's a choice between vinyl and cloth upholstery.
Options include a navigation radio, rear vision camera and ultrasonic rear park assist, with the rear vision view shown on the rearview mirror. Heavy-duty 3500 Series models include various other upgrades, such as a higher-capacity battery and alternator, as well as a heavy-duty transmission with external oil cooler. ;
