EPA Fuel Economy: 19 MPG Combined

The 2024 RAM 2500 6.7L Diesel Crew Cab delivers a combined fuel economy rating of 19 MPG according to EPA estimates. This diesel-powered truck achieves 17 MPG in city driving and 21 MPG on the highway, making it a solid choice for those seeking better fuel efficiency in the heavy-duty truck segment. The 6.7L diesel engine paired with the 6-speed automatic transmission balances power and fuel consumption, allowing owners to tackle demanding jobs while maintaining reasonable fuel costs for a vehicle in this class.

Diesel engines have long been recognized for their superior fuel efficiency compared to gasoline counterparts, and the 2024 RAM 2500’s ratings reflect this advantage. The 6.7L diesel option in the Crew Cab configuration provides the towing capacity and hauling ability that RAM trucks are known for, without sacrificing the fuel economy considerations that matter to fleet operators and individual owners alike. With the 6-speed automatic transmission optimizing power delivery across various driving conditions, this truck manages to achieve respectable MPG figures while maintaining the performance expected from a heavy-duty work vehicle.

City vs Highway Performance

The EPA ratings show a meaningful difference between city and highway performance in the 2024 RAM 2500. City driving at 17 MPG reflects the challenges of stop-and-go traffic, frequent acceleration, and lower speeds that characterize urban environments. Highway driving delivers notably better efficiency at 21 MPG, which is typical for diesel trucks when cruising at constant speeds on interstates and open roads where the engine operates at optimal RPM ranges. This 4 MPG difference between city and highway performance demonstrates how driving conditions significantly impact fuel consumption in heavy-duty diesel trucks.

Drivers who spend more time on highways can expect to see better overall fuel economy, while those in congested urban areas should prepare for fuel consumption closer to the 17 MPG city rating. The 6-speed automatic transmission in the Crew Cab helps optimize efficiency during highway cruising by maintaining lower RPMs at sustained speeds. Understanding this difference helps owners plan fueling stops and budget accordingly based on their typical driving patterns.

Annual Fuel Cost

Calculating annual fuel costs for the 2024 RAM 2500 6.7L Diesel Crew Cab requires using the combined 19 MPG rating with typical usage patterns. Based on driving 15,000 miles per year at the combined efficiency of 19 MPG, here’s the breakdown:

Annual Mileage: 15,000 miles ÷ 19 MPG = 789.47 gallons of diesel per year

Annual Fuel Cost: 789.47 gallons × $3.50 per gallon = $2,763.16 per year

This calculation assumes an average diesel fuel price of $3.50 per gallon and consistent combined driving. Owners whose driving is weighted toward highway miles may see slightly lower annual costs, while those with more city driving could experience higher fuel expenses. Diesel prices fluctuate based on market conditions, so actual costs may vary from this estimate.

Real-World MPG Expectations

Real-world fuel economy for the 2024 RAM 2500 often reflects the EPA ratings, though actual results depend heavily on driving habits, vehicle load, maintenance, and driving conditions. Owners who drive primarily on highways may achieve MPG numbers approaching the 21 highway rating, while urban drivers typically see figures near the 17 city rating. Towing and hauling loads significantly impact fuel consumption, as the added weight requires more power from the 6.7L diesel engine, reducing overall efficiency.

To maximize fuel economy, drivers should maintain proper tire pressure, keep the engine well-maintained, avoid excessive idling, and reduce unnecessary cargo weight. Smoother acceleration and maintaining steady highway speeds contribute to better fuel efficiency. The diesel engine’s torque characteristics mean drivers don’t need to rev the engine aggressively to merge or climb grades, allowing for more economical driving patterns compared to gasoline trucks.

How It Compares

Comparing the 2024 RAM 2500 6.7L Diesel to similar heavy-duty trucks provides perspective on its fuel economy positioning. The 2024 Ford F-250 Super Duty with a 6.7L Power Stroke diesel achieves 19 MPG combined, matching the RAM’s efficiency. The 2024 Chevrolet Silverado 2500HD with a 6.6L Duramax diesel reaches 18 MPG combined, slightly behind the RAM. These comparisons show the 2024 RAM 2500 is competitive in the heavy-duty diesel truck market, offering similar or slightly better fuel efficiency than key competitors in the segment.

Tips to Maximize Efficiency

• Maintain Regular Oil Changes: Keep the diesel engine running smoothly with manufacturer-recommended oil change intervals to ensure optimal combustion and fuel economy.
• Monitor Tire Pressure: Underinflated tires increase rolling resistance and reduce fuel efficiency—check pressure monthly and maintain the recommended PSI.
• Plan Routes Strategically: Minimize stop-and-go driving by planning trips during off-peak hours and combining multiple errands into single trips.
• Reduce Towing Resistance: Use aerodynamic covers for truck beds and ensure trailers are properly aligned to minimize wind resistance at highway speeds.
• Allow Proper Warm-Up: Diesel engines benefit from adequate warm-up time before driving, improving combustion efficiency and fuel economy.

Frequently Asked Questions

Q: Can I expect 19 MPG combined in real-world driving?
A: Real-world results vary based on driving conditions, cargo loads, and driving habits. Highway-focused drivers may approach or exceed 19 MPG, while city-heavy driving typically yields figures closer to 17 MPG.

Q: How does towing affect fuel economy?
A: Towing significantly reduces fuel economy, with actual impact depending on trailer weight and aerodynamics. Expect 15-20% lower fuel economy when towing compared to unloaded driving.

Q: Is diesel fuel more economical than gasoline for this truck?
A: Yes, diesel engines in heavy-duty trucks typically deliver 20-30% better fuel economy than gasoline equivalents. Diesel fuel pricing varies regionally, so total fuel costs depend on local prices.

The 2024 RAM 2500 6.7L Diesel Crew Cab represents a practical choice for buyers seeking a heavy-duty truck with respectable fuel economy. With its 19 MPG combined rating, this diesel-powered pickup demonstrates that work capability and fuel efficiency can coexist in the modern truck market.
