The Hummer H3 has plenty of looks and style on top of a remarkable recreation capacity. But does it have a powerful towing capacity as its siblings? Can it tow heavy-duty trailers without breaking the engine? How well does it perform compared to its rivals? Let’s find out.

All the automatic transmission models of the Hummer H3 with the 3.7L L5 engines can tow as much as 4,500 pounds, while the manual transmission variants (same 3.7L L5 engine configuration) can tow 3,000 pounds. However, the H3 models with 5.3L V8 AT engine variants can tow as much as 6,000 pounds.

Now that we have identified the maximum towing capacity of the Hummer H3, let’s discuss in detail what you can tow with this car. Following are various tables and details that provide you an analysis of the towing capacity of this car in relevance with several trailer types.
