All-New Chevrolet And GMC W-Series
Tuesday, 23 January 2007
LAS VEGAS – For the 2008 model year, Chevrolet and GMC are introducing an all-new W-Series that delivers more cab room, enhanced safety features and more power. The all-new W-Series also meets new, more stringent 2007 U.S. and state of California diesel emissions standards.

“The success of our W-Series is a direct reflection of its ability to deliver exactly what medium-duty customers demand from their vehicles. As with other recent enhancements, the all-new W-Series was developed with direct input from those who know this vehicle best: our customers,” said Mark Karney, GM Fleet and Commercial Operations (FCO) marketing director for vans and trucks.

Greater driver comfort

Enhancements for 2008 were especially focused on increasing driver comfort, which can correlate to increased driver productivity. It begins with a new and improved cab mounting that delivers a smoother, more comfortable ride. The cab itself is larger and more spacious, with more side-to-side and front-to-back room. This provides more seat travel, as well as increased headroom, shoulder room and legroom – on both standard and crew cab models.

To facilitate driver ingress and egress, the 85-degree swing-out door opening is wider than the previous model, as is the self-cleaning entry step. The high-back seats are covered in Tricot breathable cloth, which stays cooler in the summer and warmer in the winter. Additional 2008 W-Series driver comfort features include:

    * A 16,400-BTU high-output ventilation system
    * Air conditioning standard on gasoline models, available on diesel models
    * Tilt and telescopic steering column
    * Power steering
    * A tapered leaf front and multileaf rear suspension that deliver a smooth, comfortable ride while still handling heavy loads

Greater convenience

The all-new W-Series also features a number of improvements to further aid driver convenience, including:

    * A new dashboard with a full complement of easy-to-see gauges and warning lamps. It features a 5-din opening for such optional equipment as radios, GPS systems, rearview cameras, etc.
    * An easy-to-remove panel at the front of the cab for easy access to the wiper motor and linkage, electrical cab connections and air intake filters, facilitating maintenance of these items
    * Storage areas in the seat backs, dashboard, glove box, overhead storage shelves and rear storage organizer
    * Large map pockets incorporated into the new, fully trimmed door panels
    * Standard power windows and door locks
    * Cup holders in the center console for extra-large fountain drinks and in the dash for regular-sized cans and cups
    * An auxiliary power outlet for a cell phone or other electronics

Even more durable, safer cab

In addition to being more comfortable and more convenient, the all-new cab is built to last a long time, with greater corrosion protection from the galvanized steel panels to the electro deposit paint primer and high-quality enamel paint topcoat. The closed section and increased gussets and reinforcements also improve the durability of this new cab, as well as increasing the safety of the driver and passengers. Additional safety equipment on the 2008 W-Series includes:

    * A new seat belt design that offers easier operation and therefore promotes use
    * Low-cut side windows for added visibility
    * Larger, 17-inch by 8-inch side mirrors with integrated convex sections help improve rearward visibility and reduce blind spots alongside the vehicle
    * Available heated mirrors

5.2L diesel engine

For 2008, the overhead cam 5.2L 4HK1-TC turbocharged, intercooled, diesel engine delivers more power and reduced emissions. Horsepower increases to 205 @ 2400 rpm (up from 190) and torque increases to 441 lb.-ft. @1850 (up from 387). It covers GVW ranges from 12,000 pounds to 19,500 pounds and has a B10 durability rating of 310,000 miles, which means 90 percent of the engines should reach this mileage before a major component failure – provided good maintenance practices have been followed.

The 5.2L diesel engine is equipped with a standard fuel/water separator that is heated with returned fuel and features a dash-mounted warning lamp. This separator warns the driver when water is present in the fuel filter and needs to be drained, which helps prevent vehicle downtime and supports a more efficient operation. The 5.2L diesel can be mated to the new Aisin A465 heavy-duty six-speed automatic with double overdrive, or to a six-speed manual transmission with all forward gears synchronized. The six-speed manual will be available later in the model year.

The 5.2L diesel engine also meets more stringent Environmental Protection Agency (EPA) requirements that went into effect on Jan. 1. These regulations compel all diesel engine manufacturers to reduce nitrogen oxide (NOx) and particulate matter (PM) emissions by 90 percent compared to the previous diesel engine standards, which were established in 2004.

To reduce nitrogen oxide levels, the 5.2L diesel engine uses an advanced exhaust gas recirculation (EGR) system and a variable geometry turbocharger.

To reduce particulate matter, a ceramic honeycomb channel diesel particulate filter (DPF) was created to capture sulfate particles and soot. Exhaust gases are directed through the channels and a porous material that traps the particulates. To clear the particulates and prevent clogging, a regeneration process occurs to burn the trapped particulates and clean the filter using high exhaust gas temperatures.

Regeneration in Chevrolet and GMC medium duty trucks can occur in a number of ways. Self-regeneration is an automatic process that occurs as the vehicle is driven, and does not require driver involvement. The vast majority of vehicles will regenerate automatically. Forced, computer-initiated regeneration occurs if the vehicle operation does not produce exhaust gases hot enough for the automatic process to occur.

In the event that the computer cannot force regeneration, a control light will alert the driver to activate a dashboard switch to initiate the regeneration process. Special system-sensing and control software was developed to precisely control engine combustion and DPF regeneration.

To meet the EPA regulation for lower diesel fuel sulfur emissions, GM-designed emissions systems work efficiently with the new fuels and lubricants. The 2007 emissions regulations also require all crankcase gas emissions to be reduced. To comply, a closed crankcase system was added to reroute ventilation gases back into the engine for combustion.

Helping to reduce operating costs while increasing vehicle uptime is a new 10,000-mile oil and oil filter interval on W-Series models equipped with the 5.2L diesel engine.

Chevrolet and GMC W-Series diesel models include the W3500, W4500 (regular and crew cab), W5500 (regular and crew cab) and the W5500 HD.

Vortec 6.0L engine

For Chevrolet and GMC W-Series customers who prefer a gasoline engine, W3500 and W4500 models are available with the Vortec 6.0L V-8 engine. For 2008, the Vortec 6.0L delivers 325 horsepower – 25 more than the previous version – and 360 lb.-ft. of torque. These models are mated to the Hydra-Matic 4L80 four-speed automatic with lockup torque converter and overdrive.

The Vortec 6.0L is 50-state compliant with federal CFFV/LEV and California ULEV emissions requirements. It has a 200,000-mile design life and is backed by a three-year/36,000-mile warranty. Customers may purchase extended service plans that cover their vehicles for up to five years/100,000 miles.

Gasoline-powered versions of the Chevrolet and GMC W-Series are assembled in Janesville, Wis., while diesel-powered models are manufactured in Fujisawa, Japan.
