6.6 V8 (401 Hp) 4WD DRW Automatic Verdict:

Rating 4 stars

Performance Verdict

A highly capable gasoline option for heavy-duty tasks, combining the 6.6L V8's power with 4WD and DRW for maximum stability, traction, and payload in varied conditions.

Fuel Economy

Fuel consumption is high, as expected for a gas heavy-duty truck with 4WD and DRW. Best for those needing the capability but not the consistent extreme loads that warrant diesel.

Best Use Case: Heavy payload and towing where 4WD is essential, commercial use in challenging terrain, users who prefer gasoline and need maximum stability/traction.

Pros and Cons:

Pros:

  • • Exceptional towing and hauling capabilities, especially with the Duramax diesel.
  • • Robust and durable construction designed for heavy work.
  • • Comfortable and well-appointed interior for a heavy-duty truck.
  • • Advanced technology and safety features available.
  • • Choice of powerful gasoline or diesel engines to suit various needs.

Cons:

  • • Large size can make urban maneuvering challenging.
  • • Fuel economy is inherently low, particularly for gasoline variants under load.
  • • High purchase price, especially for top trims and diesel.
  • • Ride quality can be stiff when unloaded, typical for HD trucks.
