ST. LOUIS. Western Star, a division of Daimler Trucks North America, showcased its 4900 109 in. BBC model with a unique powertrain option at the National Truck Equipment Assn.’s Work Truck Show here.
The truck features a Detroit Diesel DD13 engine and Allison 3000RDS transmission. This powertrain combination for 109-in BBC configurations is only available in Western Star trucks, the company said.
“Western Star vocational customers demand a premium work truck that’s ready to meet the on-site challenges of their job,” said Mike Jackson, gm. “With the addition of the Allison transmission and body builder-friendly features, the 109 is the complete custom package that will get the job done.”
The 109 is the shortest BBC in its class and is ideal for construction, government, refuse and utility applications, particularly where the truck must maneuver through suburban streets or congested job sites.
Additional updates to the 109 include under hood air cleaners with inside/outside air and dash controls and a 6 gal. DEF tank. The 13-liter DD13 features 350-450 hp and 1,250-1,650 lb.-ft. of torque and includes Detroit Diesel’s BlueTec SCR technology to meet 2010 emissions regulations.
The truck is available with a 12,000 to 20,000-lb. front axle, and 21,000 to 46,000-lb. rear axles.
Western Star also announced a partnership with Allison Transmission to offer a specially designed Allison Optimized package for its trucks.
The package features shift energy management, prognostics, reduced engine load at stop, load base shift schedule, auto neutral, TES 295 synthetic fluid and warranty. The transmission is ideal for heavy haul, mixer, dump and short haul tractor applications.
“We’re working hard to provide our on-highway and vocational customers with superior powertrain solutions that meet the demands of their jobs, and partnering with Allison gets us one step closer to that goal,” said Jackson. “Allison Optimized transmissions provide our customers with a premium package that maximizes efficiency and power for a complete solution.”
