When it comes to heavy-duty work trucks, diesel engines often steal the spotlight with their massive torque and towing capacity. However, gas-powered V-8s remain the preferred choice for many buyers who prioritize everyday drivability, lower maintenance costs, and simpler operation. MotorVero's comprehensive comparison reveals how today's leading 3/4-ton gas trucks stack up in real-world fuel efficiency and performance.
Key Findings:
- Ford's 6.2L V-8 leads the pack in fuel efficiency with a combined 15.2 MPG average
- Nissan's advanced 5.6L DOHC engine pairs with a 7-speed transmission for responsive performance
- Chevrolet's proven 6.0L pushrod V-8 demonstrates remarkable longevity despite older design
- Ram's 6.4L Hemi delivers the most character but struggles with loaded fuel economy

3/4-Ton Gas Truck Fuel Economy Showdown
Our rigorous testing protocol evaluated each truck in both empty and loaded conditions (with 2,000+ pounds in the bed), simulating real-world work truck usage patterns. The results reveal significant differences in how these powertrains handle demanding workloads.
Ford Super Duty F-250 XL: Efficiency Leader
Equipped with Ford's , the Super Duty posted the segment's best combined fuel economy at . This impressive showing comes from several innovative engineering solutions:
Engine Highlights:
- Single-overhead cam design with roller rocker shafts reduces friction
- 16-valve configuration optimizes airflow
- Advanced fuel injection system maintains precise mixture control
Beyond the numbers, testers noted the Ford's powertrain delivered the smoothest operation of the group, with seamless power delivery that made it exceptionally livable for daily driving. The transmission calibration proved particularly adept at keeping the engine in its efficiency sweet spot during both highway cruising and hill climbs.
Nissan Titan XD S: The Technological Contender
Nissan's entry achieved a average with its , despite being handicapped by the extra weight of unrequested 4×4 equipment. The Titan stood out with several segment-exclusive features:
Innovative Drivetrain:
- Only 7-speed automatic in class provides closer gear spacing
- All-aluminum DOHC design reduces weight
- Direct injection improves combustion efficiency
The transmission's quick, intelligent shifting helped compensate for the engine's smaller displacement compared to competitors. Testers appreciated how readily it downshifted for passing power while maintaining smooth operation when hauling heavy loads.
Chevrolet Silverado 2500 WT: The Dependable Workhorse
Chevy's may use dated pushrod technology, but it delivered a respectable average while demonstrating why it remains a fleet favorite:
Proven Advantages:
- Simple design reduces maintenance complexity
- Cast-iron construction enhances durability
- 20 years of refinement in HD applications
While it can't match the power outputs of newer designs, the Silverado's engine excels at providing consistent, reliable performance in demanding work environments. The torque curve is ideally suited for stop-and-go work site operation, and mechanics appreciate the accessibility of service points.
Ram 2500 Tradesman: The Personality Pick
Ram's brought up the rear with a average, though it won praise for its charismatic operation:
Performance Characteristics:
- Segment-exclusive cylinder deactivation (though limited in application)
- Most powerful base V-8 in class at 410 horsepower
- Distinctive exhaust note enhances driving experience
The Hemi's relatively thirsty nature under load (just 12.1 MPG when hauling) reflects its performance orientation. The engine works hardest when pushed, but delivers satisfying acceleration that makes empty driving particularly enjoyable. Judges noted it sounded and felt more like a performance engine than a traditional work truck powerplant.

Choosing the Right Gas-Powered Work Truck
Selecting the ideal 3/4-ton gas truck depends on your specific needs and priorities. Here's how these contenders compare in key operational categories:
Best Applications for Each Truck:
- Ford F-250: Ideal for high-mileage users who prioritize fuel efficiency and refined operation
- Nissan Titan XD: Best for those wanting modern technology and responsive performance
- Chevy Silverado: Perfect for cost-conscious buyers needing proven reliability
- Ram 2500: Top choice for drivers who value character and acceleration
While diesel powertrains dominate the heavy-duty segment for extreme towing, these gas V-8s offer compelling advantages for many users. They typically cost less to purchase and maintain, avoid diesel emissions equipment complexities, and provide more immediate throttle response for daily driving.
Modern gas engines have also closed the gap in capability, with all these trucks offering payload capacities exceeding 3,000 pounds and conventional towing ratings approaching 15,000 pounds - sufficient for most commercial and recreational needs.

Future of Gas-Powered Heavy-Duty Trucks
As emissions standards tighten and fuel economy demands increase, manufacturers are developing new technologies to keep gas engines competitive:
Emerging Technologies:
- Dynamic fuel management systems (beyond simple cylinder deactivation)
- Mild hybrid systems for stop/start and energy recuperation
- Advanced thermal management for faster warm-ups
- Combined port/direct injection for optimal efficiency and power
These innovations promise to further bridge the efficiency gap with diesel while maintaining the gas engine's cost and drivability advantages. For many 3/4-ton truck buyers, the latest gas V-8s represent the sweet spot between capability and everyday usability.
