Intelligent application of power and technology Power The Cat C27 ACERT diesel engine is delivering 5% additional power to the drive train. As a result, new and more robust drive train components, including a larger drive shaft and differential gears have been designed to handle the power. Technology G Series introduces a new planetary powershift transmission control strategy called APECS. APECS takes the benefits of ECPC (Electronic Clutch Pressure Control) and adds part throttle shifting and torque shift management. The result is exceptionally smooth automotive-type shifting and ride...

Fuel Saving Strategies Solutions that support your lowest cost per ton Fuel Saving Strategies • Standard Economy Mode – G Series can adjust engine power based on your individual needs. With this feature, fuel savings are achieved by reducing power between 0.15 to 15 percent. Adaptive Economy Mode – New for G Series – requires a baseline for production from you. As the truck goes through the haul cycle, it constantly evaluates your baseline against opportunities to reduce power and save fuel. It’s fully automatic with no special operation required. Speed Limiting – while you can continue to...

Structural Integrity Designed for years of off-road service New Brake Design G Series has increased the number of springs in its brake design. This increases the force available to disengage the brakes ensuring clearances are maintained, reducing wear. A new brake wear indicator can be found on the rear wheels to help you monitor brake life. Extending brake life can also be achieved by choosing the optional Cat Engine Brake. This Caterpillar design works in conjunction with the automatic retarder control (ARC) to slow the machine. Rear Wheel Steel Spindles G Series wheel spindles are solid...
