The new engine runs on regular unleaded gasoline and is mated to a four-speed automatic transmission. All 4x2 Envoys are equipped with standard traction control and a limited-slip rear differential. All Envoys come with 17-inch aluminum wheels, although different designs adorn either trim level. Options include a chrome-look wheel and BF Goodrich tires instead of the standard Michelins. Along with the capacity, Envoy's seats themselves have grown.
Cushions are thicker and wider, and backrests are higher.
Optional seat heaters are available for the SLT only. GMC offers a separate audio zone for this seat as well, an option that can be combined with the premium Bose audio system, itself an option. In addition to the usual headphone jacks and volume control, passengers get an audio system display. The headrests pop back automatically to provide clearance. Around back, the lift gate window raises independently or along with the gate.
