Volvo Trucks is launching the Volvo VNL daycab with new Cummins Westport ISX12 G engine to “positively impact the ROI of our customers,” North American sales and marketing president Ron Huibers said in the firm’s announcement at MATS, the Mid-America Trucking Show in Louisville.
“Developing fuel-efficient technology, whether through natural gas, diesel or hybrid, is a priority,” Huibers said. “We were the first commercial vehicle manufacturer to offer EPA 2010-certified engines with no credits, and we’ve continued that legacy by focusing our efforts on offering fleets solutions that reduce their fuel costs.”
“The addition of the Volvo natural gas-powered VNL daycab is just the most recent example.”
The VNL daycab measures 123 inches bumper-to-back-of-cab and has an 80,000-pound gross combination weight rating – compared with 113-inch BBC and a 66,000 pounds GCWR for the 8.9-liter ISL G-powered VNM daycab introduced last year.
The ISX12 G boasts 400 horsepower and 1,450 foot-pounds of torque – compared with 320 hp and 1,000 lb.-ft. for the ISL G.
Like the ISL G, it requires only a three-way catalyst to meet EPA 2010 emissions standards. The methane VNL daycab is optimal for regional transport, intermodal distribution, fuel distribution or pickup and delivery, Volvo says.
Volvo says it has natural gas-powered VNL demonstrator trucks running now, and will commence production “in conjunction with commercial availability of the 12-liter gas engine.” Both CNG-compressed natural gas and LNG-liquefied natural gas variants will be available.
Pennsylvania’s Giant Eagle was the launch customer for the ISL G-powered VNM daycab (F&F, July 18, 2011).
Volvo is also promoting an integrated, “XE13” powertrain package for VN series tractors. XE13 improves fuel efficiency by some 3%, the truckmaker says, via “downspeeding” – lowering engine rpms at a given vehicle speed.
Volvo Trucks also showed its VN-chassis Mean Green, “the world’s fastest hybrid truck,” at MATS.
