Western Star Trucks Features Style Updates, Vocational Upgrades at MATS

New Badging, Engine Offerings Highlight Latest Enhancements

LOUISVILLE, KY. – Western Star Trucks showcased style updates and product upgrades for vocational applications at the 2007 Mid-America Trucking Show (MATS) in Louisville, Ky.

Western Star today introduced bold new exterior badging for both the grille bezel and the side of the hood. The iconic grille-mounted black ‘W’ with its burgundy star now features a three-dimensional appearance and a crowned star, providing for a jeweled appearance. Also, the side-mounted Western Star script has been updated with a modern font and beveled edges for a cleaner look and richer reflection.

Western Star also introduced several product improvements targeted toward the vocational market, including EPA ’07 enhancements, an upgraded MBE 4000 engine, Detroit Diesel Tier III off-highway engine emission ratings for 100 percent off-road trucks, high-strength, reduced-weight frame rails, and body builder-friendly after treatment device packaging for vocational applications.

“We’re excited to present an updated exterior badge that reinforces the strength of Western Star and its image as a serious truck for serious truckers. Plus, the product improvements targeted toward the vocational market reflect our initiative to grow our off-highway business,” said TJ Reed, product manager for Western Star Trucks. “All of these updates will be available on trucks from the Portland plant, which will begin exclusively manufacturing Western Star commercial vehicles later this year.”

EPA ‘07 Enhancements

As a result of the new emissions standards, Western Star's radiator packages have expanded. Available in sizes ranging from 1,375 to 1,875 sq. in, these radiators offer increased cooling capacity for high horsepower applications and offer the additional benefit of optimal fuel economy as a result of reduced fan-on time. Material options include lightweight aluminum for on-highway applications and copper brass for vocational applications.

In order to accommodate these larger radiators, Western Star added a drop front frame casting for the axle configurations on the 4900 FA, 4900 SA, and 4900 EX models. This allows for increased cooling capacity without exterior modifications to the traditional Western Star hood and grille.

Accommodating increased radiator sizes has also allowed for improvements in front suspensions. A 56-inch asymmetric spring provides improved roll stiffness and better handling in turns due to a shortened front length while maintaining the soft ride characteristics from the longer rear length. Plus, new steering gears and optimized geometry improve road feel, overall wheel cut, and turning radius.

Western Star has added two 18,000 lb. steer axles to its vocational axle offerings. Ideal for rugged vocational applications, the 18,000 lb. axle provides weight and cost savings as compared to 20,000 lb. axles. Both the Meritor MFS-18-133A and the proprietary AF 18.05 are now available on the 4900 FA, 4900 SA, and 4900 EX models.

Upgraded MBE 4000

The popular MBE 4000 has been upgraded to include a maximum torque rating of 1,650 foot-pounds. The lightweight and powerful MBE 4000 engine is ideal for weight-sensitive vocational applications. Plus, the optional premium braking system has been improved by providing an additional 42 BHP, giving the MBE 4000 the most braking horsepower in its class and offering impressive performance and reliability.

Tier III Off-Highway Engine Platform

The Western Star® 6900XD will be offered with a Tier III off-highway emission-rated Detroit Diesel Series 60 Engine. The Tier III engine will be ideal for 100 percent off-highway applications such as mining, quarry, and off highway construction.

“One of the key benefits of Tier III engines is that they don’t require the aftertreatment devices (ATDs) that are associated with the on-highway EPA ‘07 emissions regulations,” said Reed. “Therefore, they require less ongoing maintenance than comparable severe-duty vehicles.”

Three Million RBM Single-Channel Frame Rail

Western Star will also be offering optional lightweight, single-channel 3 million RBM frame rail for truck applications in the 4900 SA, 4900 FA, 4900 EX models. The single-channel frame rail consists of a material thickness of 7/16”, and depending on overall length can achieve up to 500 pounds of weight savings when compared to a double-channel rail of equal strength. The 7/16” single channel frame rail is ideal for weight sensitive applications, and reduces the potential of corrosion between a parent rail and frame liners.

Vocational ATD Packaging

A body builder-friendly ATD package has been developed for the Western Star 4900 FA, 4900 SA, and 4900 EX models. The ATD system – combined with air tanks – is neatly packaged under the passenger-side cab access steps. Offering a cab-mounted vertical tailpipe, the system is protected by an integral diamond plate cover and allows for clean back-of-cab access. This under-step ATD is ideal for vocational applications that require right-hand transmission PTO access and auxiliary transmissions.

Cherry Wood Instrument Panel

A cherry wood dash panel will be offered as available option on all Western Star trucks. The cherry wood instrument panel and door accents have a rich wood grain finish that coordinates with the existing wood grain sleeper cabinetry. This option supplements the current burl elm wood grain dash option.
