Cat vocational truck now in production

Updated Sep 29, 2011

Imgsize OdCaterpillar has begun production of its CT660 vocational truck for the North American market and is shipping units to customers, the company said at a media introduction event Sept. 28 in Peoria, Ill.

Caterpillar launched the CT660 six months ago at the ConExpo-ConAgg trade show in Las Vegas.

CT660 was developed using the Navistar WorkStar vocational truck as a starting point. Cat trucks will offer only one make of engine: Navistar’s 2010 EGR-only family of heavy-duty diesel engines, painted yellow and branded as Cat CT11 and CT13 diesels. The two companies jointly developed the high-pressure fuel injection system that helps enable Navistar engines to meet EPA 2010 emissions regulations without use of Selective Catalytic Reduction exhaust after treatment systems requiring Diesel Exhaust Fluid.

Cat will offer the CT660 now with either an 11-liter or 13-liter diesel engine, with horsepower ratings ranging from 330 to 475 hp. A 15-liter option is planned with power ratings as high as 550 hp, although Gary Blood, vocational truck product manager for Cat says the current 475 hp CT13 engine mated with Cat’s CX31 automated manual transmission delivers power on par with a 15 liter now.

The CX31 weighs 100 pounds more than the standard Eaton 10-speed manual gearbox offered in the CT660. Blood said it’s delivering up to an 8 percent boost in fuel economy and offers three exclusive rear PTO options for mixers and other applications.

Blood said that with the exception of “a couple of components,” the CT660 is new from the frame rails up.
