Overview
Reliable performance and low hourly operating cost
The Cat® 320 GC offers an excellent balance of reliable performance, operator productivity features and reduced costs. The 320 GC is equipped with a C4.4 engine and an aftertreatment system that eliminates downtime and diesel exhaust fluid (DEF) and meets China National IV non-road emission standards.

advantage
Up to 20% reduction in fuel consumption
A precise combination of low engine speed and a large hydraulic pump delivers class-leading performance while reducing fuel consumption.

Improved reliability and efficiency
The advanced electro-hydraulic system provides an excellent balance of power and efficiency while giving you the control you need for your precise digging requirements.

Up to 20% reduction in maintenance costs
Service intervals are extended and more synchronized than previous models, so you can get more work done at a lower cost.

Note (1) Net power advertised is the power available at the flywheel at 2000 rpm when the engine is equipped with fan, intake system, exhaust system and alternator. The power advertised is tested to the specified standard in effect at the time of manufacture.
Note (2) ¹Cat diesel engines require ULSD (Ultra-Low Sulfur Diesel, 15 ppm or less) or blends of ULSD with the following lower carbon intensity fuels**: up to 20% biodiesel FAME (Fatty Acid Methyl Ester)* or up to 100% renewable diesel, HVO (Hydrotreated Vegetable Oil) and GTL (Gas-to-liquid) fuels. Refer to guidelines for successful application. Consult your Cat dealer or Caterpillar Machine Oil Recommendations (SEBU6250) for details. *Engine without aftertreatment equipment can use up to 100% biodiesel blends (for blends above 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions of lower carbon intensity fuels are similar to conventional fuels.
