Geared toward construction and severe-duty applications, such as West Coast mixers and super dump applications, the new set-forward 109-inch BBC twin steer features a three-degree wheel cut improvement over previous designs, which offers greater maneuverability for off-road applications. “The new 4900 FA configuration option is yet another way Western Star is working to meet the needs of our vocational customers,” said Rich Shearing, senior manager of product strategy for Western Star. “Not only will it allow for better off-road capabilities and a tighter turning radius, the factory installed BBC option is more cost efficient when compared to an aftermarket conversion.” The 4900 FA 109-inch twin steer is equipped with a 450-hp, 12.8-litre MBE 4000 engine, Eaton Fuller 11-speed transmission and Meritor Tandem 40,000-pound front axles and 46,000-pound rear axles. In addition, the 4900 FA twin steer features shackled springs, rather than slipper springs, for a 30 percent ride improvement without compromising load ratings.

Western Star to use DD16 engine with BlueTec emissions technology The new Detroit Diesel DD16 engine – the latest in Detroit Diesel’s series of all-new, heavy-duty engines – will be in production for the Western Star 4900 series in March 2010 and the Western Star 6900 in July 2010. The DD16 is the most powerful engine offered by Detroit Diesel and will be equipped with BlueTec emissions technology. The DD16 displaces 15.6 litres and is ideal for owner-operators, small fleets and specialty applications that include the mining, petroleum, agriculture, logging, hazardous material and heavy-haul segments. Part of the Detroit Diesel engine family, the DD16 shares a common platform design that is leveraged on a global scale by Daimler Trucks. The DD16 features a robust core design, amplified common rail fuel system (ACRS), turbo compounding technology and superior power curves that gives drivers the torque response and pulling power they demand. It will be offered with a large variety of output and multi-torque power ratings from 1,750 to 2,050 lb.-ft. torque and 475 to 600 horsepower. In addition, the DD16’s remarkable pulling power allows the driver to haul heavier payloads up and down the steepest grades and hang in top gear longer. Thanks to the DD16’s integrated engine brake, getting down the other side is just as easy. With the DD16, Western Star customers can carry bigger loads with increased gross combination weight (GCW). Additional features include the DD16’s multi-torque ratings will help improve fuel economy without compromising the engines extreme power. The engine’s wide, flat torque curves peak at low rpm and also help with vehicle launch and maintain pulling power on steep grades.
