The 2015 GMC Savana, part of its fourth generation, is a full-size van designed for commercial use. Available in two load ratings, the 2500 and 3500, the Savana also offers two wheelbase options for various capacity needs. Engine options include a 4.8L V8 making 285 hp, a 6.0L V8 with 342 hp, and a Duramax 6.6L diesel V8 delivering 260 hp. All engines are mated to a 6-speed automatic transmission driving the rear wheels. The van incorporates basic safety features like antilock brakes and stability control, but lacks some of the advanced safety tech found in newer competitors. Notable features include an available navigation system and GMC's OnStar system, offering features like turn-by-turn navigation and automatic crash response.
