Denali 6.2 Vortec V8 (403 Hp) Automatic FlexFuel Verdict:

Rating 5 stars

Performance Verdict

Delivers the ultimate V8 power and luxury experience in a 2WD configuration. Exceptional acceleration and towing for those not needing AWD.

Fuel Economy

Still very thirsty, but potentially marginally better than the AWD Denali due to less drivetrain loss. Fuel costs remain high, especially with E85.

Best Use Case: Luxury truck buyers prioritizing maximum power and premium features for on-road use, without the need for all-wheel drive capability.

Pros and Cons:

Pros:

  • • Powerful V8 engine options
  • • Excellent towing and hauling capacity
  • • Spacious and comfortable Crew Cab interior
  • • Robust and durable build quality
  • • Available 4WD/AWD for versatility

Cons:

  • • Poor fuel economy, especially with larger engines
  • • Some V8 engines (e.g., 5.3L) prone to Active Fuel Management (AFM) issues
  • • Ride can be stiff when unladen
  • • Interior plastics feel dated compared to some rivals
  • • Large turning radius in tight spaces
