Volvo Trucks introduced the initial XE13 package with a 425 horsepower rating in September 2011. The new rating provides additional horsepower while still allowing the engine to cruise at just 1150 rpm at 65 mph.
“Our first introduction of the XE13 concept focused on exceptionally fuel-conscious fleets that spend considerable time cruising at highway speeds,” Ron Huibers, Volvo Trucks president of North American sales and marketing, said. “The new 455 horsepower rating is aimed toward the higher performance demands of long-haul fleets.”
“Integrated with our Volvo engines, the intelligence of the proprietary Volvo I-Shift automated mechanical transmission and software gives us great flexibility as we expand our “downspeeding” concept to offer improved fuel efficiency.” said Ed Saxman, Volvo Trucks product manager – powertrain.
Through the XE13 package, Volvo Trucks lowers engine rpm at a given vehicle speed, a concept Volvo calls “downspeeding.”
“Customer data shows that the XE13 package consistently operates in the engine’s “sweet spot” – 1050 rpm to 1500 rpm – with up to 70 percent of operation in the most efficient range of 1100 rpm to 1200 rpm,” Saxman said. “Operating in this range yields about a 1.5 percent fuel efficiency improvement for every 100 rpm of “downspeeding,” so the XE13 package with the 455 horsepower rating will deliver about a 3 percent fuel efficiency gain.”
Available on Volvo VN series tractors, the XE13 455 hp package is rated up to 80,000 pounds (GCWR) and includes the following components:
Volvo D13 engine with 455 horsepower and 1750 lb-ft of torque
Volvo I-Shift overdrive transmission with a 0.78:1 ratio
Axle ratios of 2.64 to 2.69
Proprietary software that facilitates seamless communication between Volvo’s integrated powertrain components.
Initially introduced in September 2011, Volvo Trucks’ XE13 powertrain package boosts fuel efficiency for Volvo customers, who are already achieving up to 8 percent improvements in fuel efficiency over EPA ’07 engines. In November 2009, the launch of Volvo’s EPA ’10 certified No Regen engines with SCR technology gave customers a 5 percent boost. Volvo’s powertrain enhancements and advanced aerodynamics announced at the 2011 Mid America Trucking Show deliver up to an additional 3 percent.
Now available with a 455 horsepower engine rating, Volvo Trucks’ XE13 powertrain package reduces fuel consumption by allowing the engine cruise at just 1150 rpm at 65 mph – about 200 rpm less than the average truck sold today.
