NPR Gas and NPR-HD Gas 6.6L V8
Production of NPR Gas (12,000-lb. GVWR) and NPR-HD Gas (14,500-lb. GVWR) models equipped with the new 6.6-liter V8 gasoline engine will begin this July.
To develop the new powerplant, engineers began with a proven small-block design and incorporated advanced Gen V technology to meet heavy-duty powertrain requirements.
The engine will be mated to a proven 6L90 six-speed automatic transmission with double overdrive and a lock-up torque converter. Both NPR and NPR-HD models will offer a 38.6-gallon stainless-steel fuel tank for extended driving ranges.
Both Standard Cab and Crew Cab models will be available with wheelbases ranging from 109 to 176 inches.
The trucks will be assembled by Spartan Motors in Charlotte, Mich., starting in July 2020.
NQR Gas and NRR Gas 6.0L V8
The new 6.0-liter V8 engine that will debut in the upcoming NQR and NRR Gas models represents the first time Isuzu has offered a gasoline engine in a Class 5 truck—and the NRR Gas will be the first gas-powered Class 5 low cab forward truck with a 19,500-lb. GVWR in the industry.
- The engine will be certified and supplied by Power Solutions International and built from a Vortec V8 block that has been customized to Isuzu specifications.
- The powerplant will produce 311 horsepower and generate 353 lbs.-ft. of torque at 4,150 rpm.
- The engine will be mated to a six-speed Allison 1000 RDS transmission with power takeoff. This will be the first time Isuzu has offered PTO in a gas-powered truck
- Like Isuzu’s new Class 3 and 4 gas trucks, both the NQR and NRR will offer a 38.6-gallon stainless-steel fuel tank.
- Customers can choose between a Standard Cab with seating for three or the Crew Cab with seating for up to seven, and wheelbases ranging from 132.5 to 176 inches.
Spartan Motors will be assembling these trucks starting later this year, and availability is anticipated in the fourth quarter of 2020 or early first quarter of 2021.
