Caterpillar 320D vs 320D2 GC - what is the difference?
The Caterpillar 320D and 320D2 GC are both 20-ton class excavators, but the 320D2 GC is a later, more fuel-efficient model designed for general construction. The 320D2 GC typically features an upgraded engine and hydraulic system that can reduce fuel consumption by up to 15% compared to the 320D, while offering similar digging performance. For used equipment buyers, the choice often comes down to budget, availability, and specific job requirements.
Model Overview and Key Specifications
The Caterpillar 320D was introduced in the mid-2000s and became a workhorse in global construction. The 320D2 GC, introduced later, is part of Caterpillar's GC (General Construction) line, which prioritizes simplicity and lower operating costs. Both machines share the same 20-ton class size, but differ in engine, hydraulics, and features.
Below is a comparison of typical specifications for used machines. Actual specs may vary by year and configuration.
| Feature | Caterpillar 320D | Caterpillar 320D2 GC |
|---|---|---|
| Engine Model | C6.4 ACERT | C4.4 ACERT |
| Net Power (hp) | 148 | 142 |
| Operating Weight (kg) | 20,300 - 21,500 | 20,000 - 21,000 |
| Fuel Consumption | Higher | Up to 15% lower |
| Hydraulic System | Standard | Optimized for efficiency |
| Typical Used Price (USD) | $35,000 - $55,000 | $45,000 - $70,000 |
Note: Prices are indicative and vary based on condition, hours, and market demand.
Performance and Fuel Efficiency
The 320D2 GC is engineered to deliver lower fuel consumption without sacrificing productivity. Its C4.4 engine and refined hydraulic system reduce parasitic losses, making it ideal for general construction, trenching, and utility work. The 320D, while slightly less efficient, is known for robust performance and is often preferred for heavier digging or tough applications. Both machines offer excellent digging forces and lift capacities, but the 320D2 GC may provide a smoother, more controlled operation.
Condition and Inspection
When buying used, condition is critical. ExcaYard performs a 150-point pre-shipment inspection on every machine, including hours verification and paint-thickness checks to detect prior repairs. We provide detailed photos and video so you can assess the machine before purchase. For the 320D, pay attention to the C6.4 engine's maintenance history, while the 320D2 GC's C4.4 engine is generally simpler. Regardless of model, check hydraulic pumps, undercarriage, and electronics.
