Flanking the GMC family grille are headlamps that set the Envoy apart from its siblings. Each headlight cluster includes a circular amber parking light, an elliptical halogen high beam, a highly elliptical high intensity discharge low beam, and a sidemarker light. A pair of large fog lamps is incorporated in the lower front valence. With this lighting package, they will see you coming.

The Envoy sports cast aluminum wheels with P235/70R15 all-season tires. Front suspension is independent, a short-long arm design with torsion bars; semi-elliptic springs are used at the rear. The Envoy has the ZW7 Luxury Ride suspension, which has shock absorbers and springs tuned for a smooth highway ride on paved or improved roads. Front shocks are by Bilstein, and Delphi premium load-leveling shocks are standard in back. The set-up is also appropriate for heavy trailering. The Envoy is rated to tow up to 5000 pounds and is pre-wired.

Power comes from GM's ubiquitous Vortec 4.3-liter V6 truck engine. This overhead-valve 90-degree V6 is tuned for truck work, with torque peaking at 2800 rpm (250 foot-pounds). It is rated at 190 horsepower at 4400 rpm. Redline is just over 5000 rpm.

The engine is mated to GM's 4L60-E 4-speed electronically controlled transmission. The Envoy's transmission has a tow/haul mode, accessed by a button on the shift lever, that reduces shifting when towing a heavy trailer and attunes the performance of the gearbox to the heavier load. The new Auto Trac 2-speed transfer case is standard as well. Modes are selected by dash-mounted buttons, including an Auto 4WD button that is not all-wheel drive, but rather a standby mode that, when rear wheel spin is detected, engages the four-wheel-drive system for as long as needed.

Four wheel disc brakes are standard, as is ABS on all four wheels.
