KIRKLAND, Wash. — Kenworth says its T680 is now available with the Eaton Fuller Advantage 10-speed automated transmission, optimized for the Paccar MX engine.
“By optimizing the Kenworth T680 with the new Eaton Fuller Advantage 10-speed automated transmission and 2014 Paccar MX-13 engine, Kenworth introduces a new opportunity for long-haul and regional operators to achieve fuel savings,” said Kurt Swihart, Kenworth marketing director. “This important opportunity with the T680 day cab, 52-inch sleeper and 76-inch sleeper configurations is something for truck operators to consider before deciding their next new truck purchase decision.”
Kenworth says the engine/transmission combo, aerodynamic enhancements and fuel-economy axles such as 6x2s can provide up to a 5% fuel savings over a standard T680. Up to 2% of that is due to the integration of the MX engine with the Fuller Advantage transmission, Kenworth says.
“The transmission’s shift points are tuned to the engine fuel map which features engine RPM and the engine load – it determines where to shift and maintain gearing at the lowest fuel consumption point,” said Kevin Baney, Kenworth chief engineer.
The automated transmission also makes it easier for drivers to achieve good fuel economy.
“Drivers typically have the largest impact on a truck’s fuel economy. Everyone drives a truck differently and the fuel economy range between a fleet’s top driver and lowest performer can exceed 1 mpg,” said Baney. “This transmission reduces this variability. Imagine the best drivers in your fleet, and cloning their shifting performance. We think the Eaton Fuller Advantage is an option that makes a lot of sense for Kenworth’s most fuel-economy conscious customers.”
