The CT681 is a Class 8 set-forward-axle model with a spacious and ergonomic cab, industrial styling, and a vocational-specific engine and transmission.
Industrial, attachment-ready design
With its set-forward axle, the CT681 allows customers affected by bridge law formulas in their states or on the interstate highway system to maximize loads. It’s also ideal for those who prefer a longer wheelbase truck for better ride quality on long hauls or rough haul roads.
Comfortable, productive cab
The ergonomic dashboard and center stack feature easy-to-read gauges that drivers can view through the steering wheel. A tuned cab air suspension system, premium grade sound insulation, and tight fitting components and trim deliver a smooth, quiet ride. Drivers can choose from multiple seat options, including the Cat Comfort Seat. They’ll also find plenty of room for paperwork, log books and other important items in the easy-to-reach side compartments, back-panel storage and oversized side pockets. Overhead, under-dash and adjustable map lights illuminate key work areas, and easy-access HVAC controls and vents are positioned for optimum air flow.
Performance-matched engine and transmission
Under the hood, the CT681 is powered by a Cat CT Series Vocational Truck Engine with horsepower ratings from 365 to 430 and peak torque ratings from 1,250 to 1,550 lb-ft. Designed for vocational applications, these engines deliver optimum horsepower/torque combinations and the flexibility to match power and performance to specific jobs and operating conditions.
Cat Connect/LINK technologies
The CT681 comes standard with Product Link, a proprietary Cat telematics system that collects data from on-board systems and transmits it via satellite and cellular networks to a secure Internet site. Using Product Link and its easy-to-use web interface, VisionLink®, truck owners and fleet managers can access accurate, timely data about how, when and where trucks are being used. With information from LINK technologies, customers can make fact-based decisions to help reduce costs, enhance productivity and improve security. An optional Vehicle Infotainment System and Bendix Tire Pressure Monitoring System are also available on the CT681.
