Detroit DT12 Transmission Available for New Western Star 5700XE


LAS VEGAS – Sept. 11, 2014 – Western Star Truck Sales, Inc., today announced the introduction of the Detroit™ DT12™ transmission into its all-new Western Star 5700XE model. The Detroit DT12 transmission will be standard on the 5700XE. 

“The DT12 complements the extreme efficiency of the 5700XE by providing enhanced fuel economy, vehicle performance and safety,” said Ann Demitruk, director of marketing for Western Star. “Customers will appreciate significant driver advantages found with the DT12 transmission coupled with the expected performance from a Western Star truck.” 

Part of the Detroit product offering, the DT12 maximizes fuel efficiency for long-haul applications while significantly improving the driver experience. Also available in the 5700XE are the Detroit DD13®, DD15® and DD16® engines as well as Detroit axles. In addition, every 5700XE comes standard with the proprietary Detroit Virtual Technician™ remote diagnostic service. 

Commented Demitruk: “Fleets can now choose a complete Detroit powertrain for ease of service and optimized performance and efficiency.” 

The DT12 is a fully automated manual transmission featuring high-speed, computer-controlled shift and clutch actuators that automatically and seamlessly select the right shift pattern and perfect clutch engagement for fuel economy and driving conditions. 

The 12-speed DT12 is available in direct or over-drive top gear configurations. 

Other features – such as Creep Mode, which simulates a torque converter to improve low speed maneuverability; Skip Shift, which automatically skips gears to achieve cruising speed sooner; and eCoast, which enables vehicles to coast when the requested speed can be achieved or maintained with the engine operating at idle speeds while preserving momentum – will further maximize fuel efficiency and performance of the 5700XE.

“The DT12 has been available for less than two years, and we’ve had an extremely positive reaction from customers,” said Brad Williamson, manager, Engine and Component marketing for Daimler Trucks North America. “We have high expectations that Western Star customers will experience the power and driver-friendly benefits of the transmission – benefits that will make the 5700XE one of the most efficient and powerful trucks in the industry.”
