• Horsepower: 355 hp
• Torque: 383 lb-ft

6.2L V8 Engine

• Displacement: 6.2 liters
• Horsepower: 420 hp
• Torque: 460 lb-ft

EPA-Estimated Fuel Economy: Breaking Down the Numbers

5.3L V8 Engine

• City: 15 mpg
• Highway: 20 mpg
• Combined: 17 mpg

6.2L V8 Engine

• City: 14 mpg
• Highway: 19 mpg
• Combined: 16 mpg

Performance vs. Fuel Economy: Striking a Balance

While the 6.2L engine boasts superior horsepower and torque, it comes at the expense of fuel efficiency. The 5.3L engine, on the other hand, offers a more balanced approach, providing adequate performance while delivering marginally better gas mileage.

Real-World Fuel Consumption: Factors to Consider

• Driving habits: Aggressive acceleration, frequent braking, and excessive idling can significantly impact fuel consumption.
• Vehicle weight: Additional weight, such as cargo or passengers, can increase fuel usage.
• Tire pressure: Underinflated tires increase rolling resistance, leading to reduced fuel efficiency.
• Terrain: Driving in hilly or mountainous areas requires more power, resulting in lower gas mileage.

Towing and Payload Capacity: Implications for Fuel Economy

The GMC Yukon is capable of towing up to 8,500 lbs with the 5.3L engine and 8,100 lbs with the 6.2L engine. However, towing heavy loads or carrying significant payloads can adversely affect fuel economy.

Technology and Features: Fuel-Saving Advancements

• Active Fuel Management (AFM): This system deactivates cylinders under light loads to improve fuel efficiency.
• Variable Valve Timing (VVT): Optimizes engine performance and fuel consumption by adjusting valve timing.
• Direct Injection: Delivers fuel directly into the cylinders for increased efficiency.

Cost of Ownership: Considering the Long-Term Impact

• Fuel costs: The higher fuel consumption of the 6.2L engine will result in increased fuel expenses over time.
• Maintenance costs: Both engines require regular maintenance, but the 6.2L engine may have slightly higher maintenance costs due to its increased complexity.

The Verdict: A Matter of Preference

Ultimately, the best choice between the GMC Yukon 5.3 vs. 6.2 gas mileage depends on individual needs and priorities. If fuel efficiency is paramount, the 5.3L engine is a more suitable option. However, if performance is a higher priority, the 6.2L engine offers unparalleled power but with a compromise in gas mileage.

The Bottom Line: An Informed Decision for Optimal Performance

By carefully considering the factors discussed in this comparison, you can make an informed decision that aligns with your driving habits, performance requirements, and financial constraints. Whether you prioritize fuel efficiency or raw power, the GMC Yukon 5.3 vs. 6.2 gas mileage debate provides valuable insights to guide your choice.
