Volvo Trucks North America on Tuesday announced the debut if its fuel efficient powertrain package, I-Torque.
Comprised of Vovlo's standard D13 Turbo Compound engine; I-Shift transmission with overdrive features, adaptive gear shift strategy and a new map-based version of the predictive cruise control Volvo I-See; and exceptionally low rear axle ratios (as low as 2.15); I-Torque enables the truck to operate optimally with up to a 31 percent increase in fuel efficient speed range, achieving up to 8.5 miles per gallon at 85 mph, according to Volvo.
“In today’s demanding and quickly changing transportation business environment, that requires a high degree of flexibility and adaptable truck performance on various terrains and routes, I-Torque is the solution for our customers who need to stay competitive with a truck where fuel economy and optimized performance is taken to the next level without any compromises," said Johan Agebrand, director of product marketing at Volvo Trucks North America. "The current business environment is a perfect example, where diesel prices are pacing well beyond $4 per gallon and the pressure on transportation is high."
The overall functionality of the I-Torque configuration is that it uses Volvo Trucks’ 13-speed I-Shift feature with crawler gear, combining the fuel efficiency advantages of direct drive with the performance and flexibility of overdrive. By incorporating I-See, low rear axle ratios and load sensing software the truck’s system will select either direct drive or overdrive to maximize fuel efficiency at highway speeds.
I-Shift together with the new version of the I-See technology, which employs real-time map-based data and GPS positioning, manages speed and gear-shifting in the most fuel-efficient way on any route or terrain and generates up to an additional 1 percent in fuel savings.
