Volvo Trucks North America (www.volvotrucks.us.com) has announced that it is boosting peak torque in its 13-liter D13 engine with the introduction of a 500 horsepower, 1,850 lb.-ft. torque engine rating. The powerful, yet fuel-efficient engine, is well-suited for linehaul, heavy-haul and on-/off-highway vocational applications.
"Added torque provides even better gradability in demanding mountainous terrains and improves startability in heavy-haul and off-road vocational applications," said John Moore, Volvo Trucks powertrain product manager. "Introduction of this new peak torque rating is truly a testament to the robust design of the D13 engine.
"Today's 13-liter engines equal the horsepower and torque of larger displacement engines, while providing improved fuel efficiency and significant weight savings."
The new rating will be available for order on all Volvo VNM, VNL, VAH and VHD models beginning in the third quarter of 2013. Previous peak torque across Volvo's product lineup was 1,750 lb.-ft.
Volvo's 500 horsepower, 1,850 lb.-ft. torque engine is an Eco-Torque rating which allows the truck to accelerate normally through all bottom gears. In the top two gears, where most of the fuel is traditionally consumed, the engine defaults to the lower torque curve, helping save fuel. The higher torque is available on demand.
"Adding the 1,850 lb.-ft. torque rating for our D13 engine is an important step as we focus on strengthening our market presence outside the long haul segment," Moore said. "We can now provide a lighter weight solution for customers currently using larger displacement engines to achieve the same torque output."
