2004 GMC Savana

GMC 2004 SAVANA - PROFESSIONAL-GRADE UTILITY

With major upgrades only a year ago, GMC's full-size 2004 Savana offers advanced functionality as a leading people- and cargo-carrier. With innovative features like all-wheel drive, a left-side entry/load door and unique side-access panels on Savana Pro models, Savana delivers value. The full-size van offers performance, safety, handling and reliability for consumers. In addition, 15-passenger vans will be equipped with the StabiliTrak vehicle stability enhancement system in an interim change during the 2004 model-year production cycle.
StabiliTrak
StabiliTrak helps drivers maintain control of vehicles during certain difficult driving conditions such as ice, snow, gravel, wet pavement and uneven road surfaces, as well as in emergency lane changes or avoidance maneuvers. The system will be standard on all 15-passenger Savana vans.




The vehicle stability enhancement system works by recognizing wheel skid. Sensors detect the difference between the steering wheel angle and the direction the driver is actually turning by 'reading' the steering wheel position, the amount of sideways force in play, vehicle speed and the vehicle's response to steering wheel input.

The system then uses the brakes to enhance control of the vehicle's direction and to help keep it on course. It automatically reduces the engine torque and applies precise amounts of pressure to the front right or left brakes to help keep the vehicle on track. These brake and engine interventions help realign the vehicle's actual path with that being steered by the driver.



Savana powertrains
A lineup of Vortec 4800, 5300 and 6000 V-8 engines and the base Vortec 4300 V-6 provide Savana with best-in-class power and economy. The V-8s include redesigned induction systems and new mass airflow sensors for quieter operation. Their specially designed air cleaner also can provide more than double the normal filter life for lower maintenance costs.

The Vortec 4800 is rated at 275 horsepower (201 kw) at 5200 rpm and 290 lb.-ft. (386 Nm) of torque at 4000 rpm and is used for heavy-duty service applications, such as the 2500 Series regular- and extended-wheelbase cargo vans.

The Vortec 5300 produces 285 horsepower (213 kw) at 5200 rpm and delivers 325 lb.-ft. (441 Nm) of torque at 4000 rpm. It comes standard in the AWD H1500 and 2500 Series models, and is optional in selected G1500 and 2500 regular/extended passenger/cargo vans.

The powerful Vortec 6000 V-8, producing 300 horsepower (224 kw) at 4400 rpm and 360 lb.-ft. (488 Nm) of torque at 4000 rpm, provides more than enough muscle for heavy-duty hauling. The 6000 comes standard in the G2500/3500 regular and extended wheelbase passenger vans and is mated to the Hydra-Matic 4L80-E transmission. (posted on conceptcarz.com)

The Vortec 4300 V-6 is fitted standard with multi-port fuel injection and produces 200 horsepower (149 kw). It uses the Hydra-Matic 4L60-E transmission. (posted on conceptcarz.com)

All Savana automatic transmissions incorporate GM's unique Tow/Haul mode, which reduces the frequency of shifting and improves predictability of shifts during towing.

Chassis and suspensions
Three-piece boxed frames provide 28 percent to 43 percent more torsional stiffness, depending on the model, and upgraded independent front suspensions offer flat handling and more isolation from road noise. Three all-wheel-drive 'H' models use a full-time AWD system to continuously transfer torque from slipping wheels to those with traction.

Standard rack-and-pinion power steering gives light-duty models a quicker, more responsive feel. The integral power recirculating-ball steering gear in heavy-duty models also has been upgraded for better durability. Four-wheel disc brakes with ABS are standard on all vans.

An industry-first 60/40 left-hand-side hinged door provides the segment's most flexible loading capability. Available on regular-length passenger, conversion and cargo vans, it offers complete driver's-side access to the second-row seat/cargo compartment and third-row seat/rear compartment.

Enhanced comfort, safety
Savana's heating, ventilation and air conditioning (HVAC) system has been upgraded. But more important is the front-seat dual-level air-bag system, standard in models up to 8,600 pounds (3,901 kg) GVW. The restraint system is designed to detect vehicle deceleration and provide an appropriate amount of air-bag inflation. The dual-level air-bag system senses the severity of impact and determines exactly how much inflation should be supplied when deploying the air bags.

Other safety enhancements include driver- and front-passenger safety belts, three-point lap-and-shoulder belts in all first- and second-row seating positions and a child seat tether-type restraint anchorage system in passenger vans. Savana also offers heated outboard rearview mirrors with integrated turn signals.

For added safety and security, GM's factory-installed OnStar system is available in passenger and conversion van models. OnStar is the nation's leading provider of in-vehicle safety, security and information services using the Global Positioning System (GPS) satellite network and wireless technology. OnStar services include automatic notification of air-bag deployment, stolen vehicle location, remote door unlock, emergency services dispatch, roadside assistance, remote diagnostics, route support, convenience services and OnStar Concierge.
