Later this year, the Class 3 NPR and the Class 4 NPR-HD will offer 6.6L V8 gasoline engines. “This engine provides the optimum combination of increased fuel efficiency, improved acceleration, and outstanding durability, all while meeting the next set of restrictive emission requirements,” Skinner said.
Highlights of the 6.6L V8 gasoline engine include direct fuel injection to provide fuel control, variable valve timing, 350 horsepower with a peak 425 lb-ft of torque at 3,800 rpm, and a design life of 200,000 miles. The vehicles will also feature a 38.6-gallon stainless steel fuel tank.
Production of the NPR and NPR-HD with the 6.6L V8 gasoline engine will begin in July of this year, said Skinner.
Isuzu also revealed that later this year, Isuzu will introduce a new 6L V8 gasoline engine in the Isuzu NQR and NRR, the company’s first gasoline engine offered in a Class 5 low cab forward truck. In the case of the NRR, it's the first 19,500 GVWR Class 5 low cab forward truck with a gasoline engine, said Skinner.
