COLORADO SPRINGS, Colo. — A Daimler Trucks North America official says the integrated Detroit Powertrain is at the core of every facet of the new Freightliner Cascadia’s greater efficiency and performance.
“We challenged ourselves to find ways to make an immediate impact on our customers’ bottom lines,” said Kary Schaefer, general manager, marketing and strategy for DTNA. “Instead of focusing on just individual components, we took a holistic approach and provided an integrated solution to bring additional fuel efficiency.
“The engine, transmission and axles of the integrated Detroit Powertrain are designed, engineered and manufactured to lower our customer’s Real Cost of Ownerships in the new Cascadia.”
The available downsped 400hp/1,750 lb/ft. Detroit DD15 and Detroit DD13 engines are optimally matched to the updated EGR system to deliver enhanced performance, spokesmen noted.
The DD15 is now lighter and can go longer between routine service appointments, Schaefer said, adding that the GHG17-certified DD15 also features a variable-speed water pump for lower impeller speeds, resulting in less parasitic load; an improved DDEC electronics system for better engine and after-treatment system management; and an optimized piston design for less friction and oil consumption.
The new DT12 has also been updated to improve fuel efficiency and reduce friction by using super-finished gears and by using low viscosity transmission oil, Schaefer said. It also features the latest generation of intelligent powertrain management (IPM4), which uses a GPS-based system to anticipate upcoming road terrain and maximize the powertrain’s ability to utilize fuel most effectively.
The new Detroit rear axles have features such as lower sump volume, gear-set coating, friction-reducing gear cutting and optional axle lubrication management that reduces parasitic loss and improves fuel economy. New Detroit rear drive axle ratios 2.28 and 2.16 are available in the new Cascadia to further promote downspeeding and thus improved fuel economy.
“We are driven to find and develop the right solutions that maximize truck, powertrain and driver performance,” Schaefer said. “That dedication goes beyond fuel savings; it also centers on active safety systems like Detroit Assurance that protect everyone on the road.”
The latest Detroit Assurance 4.0 suite of safety systems features driver-friendly controls and an interactive dash display that deliver a high level of on-road control and safety in the new Cascadia. The system includes active brake assist, adaptive cruise control and lane departure warning, OEM spokesmen said.
Active brake assist is always on and part of the radar; it can potentially mitigate collisions through partial and full braking on moving objects, as well as full braking on stationary objects in the new Cascadia.
An optional video-capture feature records safety-related events for 20-30 seconds of video before, during and after the incident, Schaefer said. The saved recording, which is available through the Bendix SafetyDirect Web portal, informs fleet managers of driver training opportunities.
Detroit Assurance is integrated with the Detroit engine, transmission, braking system and dashboard to enhance driver safety by mitigating collisions.
“There are so many challenges that drivers face on the road today, including the performance of other drivers and road conditions. We will continue to improve our safety offerings to help drivers return home accident-free,” Schaefer said.
