Cat offers vocational truck

Caterpillar’s CT660 vocational truck isn’t merely an International Workstar with yellow paint. Caterpillar engineers say their new truck is “essentially new from the frame rails up.”

The CT660 vocational truck is offered with three sizes of Navistar MaxxForce engines.

The set-back axle configuration Class 8 truck goes into production this month, with deliveries to begin in July.

Caterpillar CT11, CT13 and forthcoming CT15 engines are Navistar MaxxForce engines, with displacements of 11.1, 12.5 and 15.2 liters, respectively. Horsepower ratings range from 330 to 550 and peak torque ratings range from 1,450 to 1,850 lb.-ft.

Cat engineers put their own distinctive stamp on this truck with styling derived from the company’s wheel loader line. They also emphasized cab ergonomics.

The CT660 has a brushed aluminum grille surround. The aerodynamic hood features a sloped design for increased visibility and decreased drag for greater fuel economy.

The truck’s instrument cluster and center stack feature an integrated speedometer/tachometer that can be read through the steering wheel. Cat offers its Cat Link equipment telematics system as standard, with a complimentary three-year subscription on all CT660 trucks. The system gives drivers and fleet managers access to data including fuel economy, hours of operation, vehicle location, maintenance and trouble-shooting information. Other in-cab features include a premium sound insulation system to reduce road noise and a new HVAC system.

MaxxForce 15

The new MaxxForce 15 diesel is available with up to 550 horsepower and 1,850 lb.-ft. of torque. Peak torque is reached at 1,000 rpm and holds steady to 1,600 rpm, the company says. This reduces gear shifts in uphill terrain and allows for shifting at lower speeds when accelerating.

Navistar’s new 15-liter engine, designed for off-highway applications, uses exhaust gas recirculation to meet emissions requirements.

The MaxxForce 15 will be built in Navistar’s Huntsville, Ala., engine plant and is available in vocational configurations. Engine options for on-highway (non-vocational) applications will be available in late summer.


Freightliner introduces Severe Duty trucks

Freightliner has released a new family of work trucks – the Severe Duty line – aimed at Class 7 and 8 vocational markets.

Freightliner’s new Severe Duty line of Class 7 and 8 vocational trucks replaces Daimler’s Sterling line and features a new styling designed to differentiate the truck from Freightliner’s long-haul products.

The SD series will comprise 108- and 114-in. bumper-to-back of cab configurations — both with set-back axle positions as well as a Coronado SD version for extreme heavy-hauls and severe off-road applications. The 108SD features a 42-in. set-back axle with rating from 10,000 to 20,000 pounds and single and tandem rear axle options from 21,000 to 46,000 pounds. Power options include a standard Detroit Diesel DD13 and Cummins ISB and ISC diesels. strives to maintain an open forum for reader opinions. Click here to read our comment policy.
