Not much changes on the Savana for 2007, but what does is significant. The V-6 engine that was standard on Passenger Van 1500 models last year has been replaced with a more powerful V-8, specifically a 295-hp 5.3-liter engine that delivers 335 lb.-ft. of torque. What’s more is that customers can order an environmentally-friendly FlexFuel version of the engine capable of running on an ethanol/gasoline mix.
