21 MPG combined makes the 2025 Ram 1500 4WD with the 3.6L V6 a deceptively efficient workhorse, a smart choice for those who need truck capability but don’t want to live with the gas station remorse often associated with full-size pickups. This isn’t a truck trying to be a commuter car; it’s a truck that acknowledges the cost of ownership while still delivering the uncompromising utility and comfortable ride Ram is known for. Owners of this specific configuration are typically not chasing ultimate towing bragging rights, nor are they weekend off-road warriors. They’re the demographic who values the versatility of a full-size truck for home improvement projects, hauling recreational gear, or simply appreciating the commanding presence and spacious cabin, all while keeping a sensible eye on the pump.

City and highway performance

The EPA rates the 2025 Ram 1500 4WD 3.6L 6-cyl at 19 MPG in the city and 24 MPG on the highway. These figures are surprisingly competitive for a vehicle of this size, weight, and capability. The standard 8-speed automatic transmission plays a significant role here, expertly managing gear changes to keep the engine in its most efficient band. In city driving, where stop-and-go conditions usually punish larger vehicles, the Ram’s mild-hybrid eTorque system (a standard feature on this engine) subtly assists with acceleration from a standstill and allows for smoother engine restarts, contributing directly to that 19 MPG figure. On the open road, the V6, while not a powerhouse, maintains highway speeds with ease, allowing the transmission to settle into higher gears and maximize that 24 MPG highway rating. It’s a powertrain designed for balance, not outright speed, and its fuel economy reflects that.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,100 for the 2025 Ram 1500 4WD 3.6L 6-cyl. This figure is calculated based on an average of 15,000 miles driven per year, split between city and highway driving, and using national average fuel prices. For many truck buyers, this annual cost represents a tangible saving compared to V8-powered alternatives. It brings the overall running costs closer to those of larger SUVs or even some sedans, making the Ram 1500 a more financially palatable option for those who genuinely need a truck but aren’t looking to spend significantly more at the pump each year. Understanding this specific cost allows potential owners to budget effectively, confirming that the Ram’s versatility doesn’t necessarily come with an outrageous ongoing fuel bill.

Real-world expectations

In real-world driving, the 2025 Ram 1500 4WD 3.6L eTorque often meets or slightly exceeds its EPA estimates, particularly on the highway. Owners report that maintaining a steady 65-70 MPH cruise can consistently yield numbers at or even above the 24 MPG mark. City driving, however, is more variable. Aggressive acceleration and frequent short trips will inevitably dip below the 19 MPG city rating. The eTorque system’s smooth start/stop functionality is key in urban environments, and drivers who allow it to do its work without overriding it tend to see better results. Hauling significant loads or pulling a small trailer will, of course, reduce efficiency, but for typical light-duty truck use – trips to the hardware store, commuting, or weekend excursions – the 21 MPG combined is a realistic expectation. The truck’s smooth ride and comfortable cabin also encourage a more relaxed driving style, which invariably aids fuel economy.

How it compares

When placed against its direct competitors with similar configurations, the 2025 Ram 1500 4WD 3.6L 6-cyl holds its own, often besting them. A Ford F-150 4×4 with the 2.7L EcoBoost V6, for instance, typically achieves around 18 MPG city, 23 MPG highway, and 20 MPG combined, making the Ram slightly more efficient on paper. The Chevrolet Silverado 1500 4WD with its 2.7L Turbo high-output engine is rated at 18 MPG city, 20 MPG highway, and 19 MPG combined, placing the Ram in a considerably more favorable light for highway efficiency. The Toyota Tundra 4×4 with its base i-FORCE 3.4L twin-turbo V6 comes in at 17 MPG city, 22 MPG highway, and 19 MPG combined, again showing the Ram’s V6 to be a strong contender. For buyers prioritizing overall fuel efficiency without sacrificing four-wheel-drive capability in a half-ton truck, the 1500 MPG across all years with the 3.6L Pentastar eTorque engine stands out. This is a good choice for those who appreciate the best-in-class interior and ride quality that define all Ram fuel economy data, alongside a genuinely competitive fuel economy figure.

Tips to maximize efficiency

Maintaining proper tire pressure is important for the Ram 1500. Underinflated tires increase rolling resistance and force the engine to work harder, directly impacting your 19 MPG city and 24 MPG highway figures. Check your tire pressure at least once a month and adjust to the manufacturer’s recommended settings, typically found on a placard inside the driver’s door jamb.

Smooth driving habits will yield considerable benefits. The 3.6L eTorque system performs best when not subjected to aggressive acceleration and braking. Anticipate stops, coast where safe and appropriate, and maintain a consistent speed on the highway to allow the 8-speed transmission to settle into its most efficient gear.

Consider the weight you’re carrying. Unnecessary items in the bed or cab add significant weight, reducing your achievable MPG. Regularly remove anything that isn’t essential for your daily tasks. Even small amounts of excess weight can chip away at your fuel economy over time.

Regular maintenance is crucial for optimal fuel economy. Adhere to the factory-recommended service intervals, ensuring your engine air filter is clean, spark plugs are in good condition, and oil changes are performed on schedule. A well-maintained engine runs more efficiently and delivers better fuel mileage.

Use the truck’s technology to your advantage. The eTorque system’s engine start/stop function is designed to save fuel in stop-and-go traffic; allow it to operate. If your Ram is equipped with an ECO driving mode, engage it to optimize throttle response and transmission shifts for maximum efficiency during everyday driving.
