2008 GMC Envoy

Overview

The GMC Envoy is a midsize sport utility vehicle designed to deliver full-size performance and versatility combined with comfort and roominess.

  • For 2008, Envoy will be available in the following configurations:
  • 2WD and 4WD
  • Two trim levels and three Preferred Equipment Groups (PEGs) SLE-1 (3SA), SLE-2 (3SB) and SLT (4SA).

Top Ten Features

  • 1. NHTSA 5-star rating For each of the last seven model years, the GMC Envoy has earned a 5-star rating for both front and rear seat occupants in the side-impact crash test conducted by the National Highway Traffic Safety Administration as part of their New Car Assessment Program1.
  • 2. New standard head-curtain side-impact air bags with rollover protection Now standard on every Envoy model, these air bags help reduce injuries to occupants in outboard seating positions in side-impact and rollover crashes.
  • 3. LATCH child seat anchors Every Envoy model is equipped with LATCH child seat anchors that use a top leather strap anchor and two lower anchors located between the seatback and bottom cushion to secure compatible child safety seats without using the safety belt. The LATCH system helps make buckling children easier and more secure.
  • 4. Standard OnStar A one-year OnStar Safe & Sound Plan is standard on every Envoy model. Also available is the Directions & Connections Plan, which includes OnStar Turn-by-Turn Navigation.
  • 5. StabiliTrak - Stability Control System with Proactive Roll Avoidance StabiliTrak is a stability enhancement system that improves control on all road surfaces at all speeds.
  • 6. Tire Pressure Monitoring This standard system electronically transmits pressure from each tire to the Driver Information Center (DIC) so the driver can take action to ensure that all tires are properly inflated.
  • 7. Automatic AutoTrac 4WD All four-wheel drive models are equipped with GM’s exclusive AutoTrac system that automatically transfers power to the front axle when slippage occurs at the rear wheels. This system can transfer from 9%-100% of power to the wheels with the most traction.
  • 8. Standard XM Satellite Radio Now standard on all models, XM delivers over 170 crystal clear digital channels from coast to coast and includes access to XM Radio Online. Includes three trial months with no obligation. Requires paid subscription after trial expiration.
  • 9. Available navigation radio A large 6.5" LCD color screen with touch-screen technology is the centerpiece of this advanced system. The navigation radio uses a DVD-based map archive, global satellite positioning (GPS) and vehicle position sensors to determine the vehicle’s location and accurately navigate to the driver’s desired destination.
  • 10. Best coverage in America All 2008 Envoys feature the GM 5-year/100,000-mile warranty.

Power & Handling

  • Vortec 4.2L I6 engine The Vortec 4.2L I6 produces impressive horsepower, and runs so quietly at idle that a starter-interrupt feature, called Intelli-start, has been added to prevent re-engaging the starter while the engine is running. - 285 hp @ 6000 rpm. - 276 lb.-ft. of torque @ 4700 rpm.
  • Automatic transmission Envoy’s standard transmission is a smooth-shifting, electronically controlled 4-speed Hydra- Matic with overdrive that is perfectly matched to transfer the power output of the Vortec 4.2L engine.
