2007 GMC ENVOY AND ENVOY DENALI DELIVER COMFORT AND CAPABILITY
For 2007, StabiliTrak electronic stability control system and GM's tire pressure monitoring system are standard on all models. StabiliTrak helps drivers maintain control during sudden maneuvers or low traction conditions by using a comprehensive series of sensors to measure acceleration, deceleration, §teering angle and yaw rate. By monitoring these inputs, the system automatically controls the vehicle to help maintain the driver's intended path when a measurable deviation from the intended course is detected. The system maintains control by regulating vehicle acceleration or applying the brakes at any wheel.
Envoy and Envoy Denali are offered in a roomy, midsize package that rides on a 113-inch wheelbase (2,869 mm); the extended-length models are discontinued. The robust Vortec 4.2L six-cylinder is standard in Envoy models, while the powerful Vortec 5.3L V-8 is standard wîth Envoy Denali. The Vortec 5.3L is equipped wîth GM's fuel-saving Active Fuel Management technology, while regulated voltage control is added to both engines for '07, also enhancing fuel economy. Both vehicles come wîth an electronically controlled four-speed automatic transmission and are available in 2WD and 4WD models.
Envoy and Envoy Denali offer a myriad of entertainment choices. In addition to the AM/FM stereo and CD player, owners may also opt for an MP3 player, XM Satellite Radio (continental Ú.S. only), a Bose premium sound system, touch screen navigation or a rear-seat DVD entertainment system.
Envoy Denali takes GMC's midsize SÚV platform to the pinnacle of comfort and style, wîth specific design cues – including the iconic chrome grille – standard 18-inch wheels and tires and a host of standard amenities. Safety
In 2006, Envoy models added GM's StabiliTrak electronic stability control (ESC) wîth Proactive Roll Avoidance as standard equipment. For 2007, GM's tire pressure monitoring system is standard on all models. StabiliTrak also is standard.
StabiliTrak helps drivers maintain control during sudden maneuvers or low traction conditions by using a comprehensive series of sensors to measure acceleration, deceleration, §teering angle and yaw rate. By monitoring these inputs, the system automatically controls the vehicle to help maintain the driver's intended path when a measurable deviation from the intended course is detected. The system maintains control by regulating vehicle acceleration or applying the brakes at any wheel.
Along wîth standard StabiliTrak and the new tire pressure monitoring system, safety features include available head curtain side air bags that inflate from the roof rail between the A-pillar and side window header. The air bag is designed to deploy in certain moderate to severe side impacts, to help provide protection for front- and second-row outboard passengers.
Vehicles equipped wîth head curtain side air bags feature an integral rollover protection sensing system that helps protect occupants in a rollover event by triggering both the side curtain air bags and safety belt pretensioners. The rollover-sensing module, located on the center tunnel under the rear seat, uses a complex algorithm based on lateral and vertical accelerations, roll rate and vehicle speed to determine whether to deploy the safety systems. Additional Envoy safety features include:
- Three-point safety belts in all seating positions
- Dual-stage frontal air bags
- GM's Passenger Sensing System (PSS)
- Push-pull power window switches
- LATCH (Lower Anchors and Tethers for CHildren) system for child safety seats
- Enhanced passenger seat belt reminder system
- Low-drag brakes
All models feature OnStar Generation 7, which includes Advanced Automatic Crash Notification (AACN) system, making crash data available to 911 centers to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. ACCN does not require air bag deployment. Envoy powertrains
Powering the Envoy Denali is the robust, all-aluminum Vortec 5.3L V-8. It delivers 300 horsepower (224 kW) and 330 lb.-ft. of torque (447 Nm)**, for excellent step-off acceleration and a broad torque range. The result is §egmènt-leading standard towing capability – up to 6,600 pounds (2,994 kg) in 2WD Envoy Denali models.
The Vortec 5.3L engine is equipped wîth GM's fuel-saving Active Fuel Management technology, which enables fuel economy gains of up to 5 percent in certain light-load driving conditions by reducing the number of cylinders engaged in the combustion process. A sophisticated, next-generation engine controller determines when to deactivate cylinders, allowing the engine to maintain vehicle speed in lighter-load conditions – such as highway cruising. When the cylinders are deactivated, the engine effectively operates as a V-4, wîth alternate cylinders on each cylinder bank disabled. The engine seamlessly returns to V-8 mode the instant the controller determines the vehicle speed or load requires additional power.
The standard engine on Envoy is the award-winning Vortec 4.2L 24-valve, dual-overhead-cam inline six-cylinder engine. It is rated at 291 horsepower (217 kW) and 277 lb-ft. (375 Nm) of torque* and provides the muscular yet smooth performance of many V-8 engines wîth the fuel efficiency of a six-cylinder.
Both engines feature new regulated voltage control, which enhances fuel economy by reducing the load on the engine required to drive the alternator in certain conditions. The engines are coupled to the rugged Hydra-Matic 4L60-E electronically controlled four-speed transmission. (posted on conceptcarz.com)
All Envoy models are available in two-wheel drive and wîth Autotrac four-wheel drive. *SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using this procedure and expects to use it for all newly rated engines in the future.Source - GMC
