Isuzu Introduces Medium-Duty Chassis

FLAT, straight frame rails and an automatic transmission with PTO provisions are part of the new low-cab-forward chassis from American Isuzu Motors.

The Isuzu NQR is a Class 5 truck rated at 16,500 lb GVW. The rating provides the NQR with a body/payload capacity of between 10,382 lb and 10,592 lb. Available with a choice of four wheelbases, the NQR can accommodate bodies ranging from 12 feet to 22 feet in length.

The NQR comes standard with a 6,830-lb front axle and a rear axle rated at 14,500 lb. With combined axle capacities that exceed GVW by almost 5,000 pounds, the NQR offers flexibility in terms of weight distribution.

Isuzu is targeting the NQR for a range of applications, including refrigerated vans, heavy-duty parcel delivery, car retrieval, refuse collection, construction, and dump truck service.

The backbone of the NQR is a channel ladder-type frame with rails spaced 33.5" apart. Yield strength is 44,000 psi, with a section modulus of 7.2" and an RBM of 316,800 lb/ft/in. A 33-gallon fuel tank, along with a fuel/water separator, is mounted on the right frame rail.

Power for the NQR comes from a new Isuzu 4.75-liter turbocharged diesel. The inter-cooled, direct-injected 4HE1-TC is rated at 175 gross horsepower when turning at 2700 rpm. It generates 347 ft/lb of torque at 2000 rpm.

The NQR comes with a choice of transmissions, with a six-speed overdrive manual as standard. An Aisin 450-43LE automatic transmission is optional. The transmission comes with a PTO opening on the left side.

Braking on the NQR includes hydro-boost hydraulic system, large front disc brakes, self-adjusting drum brakes at the rear, and load-sensing proportioning valve. An exhaust brake, offered as standard equipment, supplements the brake system.

In production now, the first of the new chassis are expected to arrive at dealerships beginning in February. Among other announcements from Isuzu:

The company is creating Isuzu Motors Acceptance Corp (IMAC), a captive financial arm for Isuzu dealers and customers.

Parts are being reduced as much as 57% for engines and an average of 38% for brake components for some Isuzu models.

Additional warranty packages will be available to provide customers with the specific coverage they need. The Isuzu Truck Owner Protection Program (ITOP) will be available for every new Isuzu truck.

Under a certified used truck program, Isuzu will refurbish vehicles meeting certain age and mileage requirements. These vehicles will carry a warranty from Isuzu.
