About GMC Envoy


Early in 2001 saw the debut of the second generation GMC Envoy, which debuted as a model for the year 2002. Following in the footsteps of the Chevrolet Trailblazer, which succeeded the Chevrolet (S-10) Blazer, the GMC Jimmy five-door was succeeded by the Envoy in 2002.

2002 Sport/Utility of the Year award recipient from Motor Trend magazine was the GMC Envoy. From 2002 until 2005, the I6 engine found in the 4200 Vortec 4200 engine was recognized as one of Ward’s 10 Best Engines.

The body-on-frame GMT360 chassis architecture was used for the development of the second generation of the GMC Envoy. The GMT360 chassis was developed from the ground up specifically for use in SUVs, marking the end of its commonality with GM compact pickup trucks. The frame rails are hydroformed throughout their entire length and fully boxed at the ends. The length of the wheelbase increased to 113 inches, which is six inches longer than the length of the wheelbase on the first generation. Additionally, for the first time, an extended-wheelbase version was introduced, which had a wheelbase length of 129 inches (1 inch shorter than the GMC Yukon XL).

The double-wishbone independent configuration with Bilstein shock absorbers was utilized in the front suspension of the vehicle. The rear axle featured a load-leveling air suspension as an option, and the rear suspension featured a 5-link solid rear axle as standard equipment.

The GMT360 Envoy made its debut in 2002 with an all-new standard engine, a Vortec 4200 4.2L inline-6, which replaced the 4.3L V6 that was previously equipped with the vehicle. The “Atlas” engine was the first inline-6 produced by GM in North America since 1984, and it was capable of producing 270 horsepower (80 more than its V6 predecessor). Beginning in 2003, purchasers of the Envoy XL had the option of purchasing a 290-horsepower, 5.3-liter V8 engine. The output of the 5.3L V8 was increased to 300 horsepower in 2005 thanks to an update that included a variable-displacement system called Displacement on Demand (which uses only 4 of the engine’s 8 cylinders when under low load).

In addition to the typical setup with the rear wheels driving the vehicle, the GMT360 Envoy was also available with either permanent two-wheel drive or a four-wheel drive system called “Shift On-Demand” that featured two-wheel drive, automatic four-wheel drive, high-range and low-range four-wheel drive. Both a rear “Posi-Trac” limited-slip differential as well as an Eaton automatic rear locking differential were available as options for the rear axle.

For the 2003 model year, GMC began offering several options as stand-alone features (instead of grouping them together), and front-seat side airbags were demoted to optional status.
