The average towing capacity for an SUV largely depends on its engine type; for example, SUVs with V6 engines can tow about 3,500 pounds of cargo, according to Autos.com. SUVs with V8 engines haul from 5,000 to 6,500 pounds of cargo, and some can haul even heavier loads.
SUVs that have a type of V8 engine called a HEMI engine can perform serious towing at more than 7,500 pounds, says Autos.com. However, V6 engines tend to be better for fuel economy.
Other factors in how much weight a SUV can tow include its transmission, brakes and rear axle, according to Edmunds.com.
