Fuel Efficiency:

The CT660 offers unique engine ratings created specifically for vocational applications, resulting in the best horsepower/torque combinations to positively impact fuel economy. Additional factors that will also positively impact the CT660’s fuel economy include the truck engine’s Advanced EGR system, which takes advantage of the latest in fuel injection technology.

Fuel efficiency can also be improved through use of the CX31 Automatic Transmission. When appropriate, the CX31 will engage the torque converter lock-up clutch, which couples the engine directly to the driveline and results in enhanced fuel economy and performance. These are just a few of the reasons why we fully expect the CT660’s fuel economy will equal or surpass competitors’ trucks.


Cat Product Link:

Cat Product Link is a comprehensive fleet and asset management solution that is standard equipment for the CT660. Through remote monitoring and cellular notifications, owners can manage a host of truck use aspects including service and maintenance requirements and fuel use and costs. Such information can be used to extend the life of the engine and improve fuel efficiency.
