The CT660 is designed by Caterpillar but powered and manufactured by Navistar for North America. It is a Class 8, set-back-front-axle vocational truck with the option of Cat-branded CT11 or CT13 in-line, six-cylinder diesels (10.5-liter rated up to 390 hp or 12.4-liter at up to 475 hp) or a CT15 with up to 550 hp and 1,850 lb.-ft. of torque, and 116-in. or 122-in. bumper-to-back-of-cab (BBC). Cat's CX31 automatic transmission delivers power to the differentials. A lock-up torque converter is said to lock at about mid-speed in all but the first gear range, for improved efficiency. The CT660 can also be specified with an Eaton manual or UltraShift Plus Vocational gearbox. A C15 engine is expected in the first quarter of 2012, and introduction of a CT680 truck built around the set-forward front axle is scheduled for the first quarter of 2013.
