23 MPG combined makes the 2025 Ram 1500 HFE 2WD 3.6L 6-cyl an efficient entrant into the full-size truck market, an almost unheard-of number for a vehicle of this size and capability just a decade ago. This isn’t a truck built for hauling construction materials to a job site every day, nor is it the choice for someone routinely towing 10,000 pounds. The Ram 1500 HFE, High Fuel Economy, is precisely what its designation implies: a workhorse for the individual or small fleet prioritizing efficiency above maximum payload or tow ratings. This is the truck for the contractor who occasionally pulls a small trailer, the landscaping business with lighter loads, or the individual who appreciates the utility of a truck but spends most of their time commuting or running errands. They value the Ram’s comfortable ride, its well-appointed interior, and its undeniable presence, but they also want to minimize the pain at the pump as much as possible for a vehicle in this class.

City and highway performance

Breaking down the 23 MPG combined figure, the 2025 Ram 1500 HFE delivers an estimated 20 MPG in city driving and a commendable 26 MPG on the highway. Ram achieves this balance through the well-regarded 3.6L Pentastar V6 engine paired with the smooth and responsive 8-speed automatic transmission. The Pentastar, despite its venerable status, remains a strong performer, offering a good blend of power for everyday tasks without consuming excessive fuel. Its naturally aspirated design means predictable power delivery, and Ram’s optimization for the HFE trim focuses on minimizing parasitic losses and optimizing shift points. The 2WD configuration also plays a crucial role in these numbers, shedding the weight and driveline drag associated with a 4WD system. For urban environments, the refined transmission manages to keep the V6 in its most efficient operating range, and on the open road, the 8-speed allows for low-RPM cruising, contributing significantly to that 26 MPG highway figure. For a truck that still offers full-size utility, these numbers are genuinely impressive and speak to a deliberate engineering effort to carve out a niche for the fuel-conscious truck buyer.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,900 for the 2025 Ram 1500 HFE 2WD 3.6L 6-cyl. This figure is calculated based on a standardized assumption of driving 15,000 miles per year, with a combination of 45% highway driving and 55% city driving, and using national average fuel prices. This provides a tangible benchmark for prospective owners to understand the yearly financial outlay purely for fueling the vehicle. For someone stepping out of an older, less efficient full-size truck, or even a larger SUV, this $1,900 annual fuel cost represents a significant saving. It underscores the “High Fuel Economy” designation, demonstrating that while it’s still a truck, its running costs are considerably lower than many of its heavier-drinking siblings or rivals. This transparent estimate helps buyers budget effectively and confirms the HFE’s mission to offer truck utility with more wallet-friendly operation.

Real-world expectations

While the EPA’s 23 MPG combined rating is an excellent benchmark, real-world fuel economy for the 2025 Ram 1500 HFE will always be subject to driving conditions and habits. For owners who do a significant amount of highway cruising, especially at moderate speeds, consistently achieving or even slightly exceeding the 26 MPG highway figure is entirely plausible. The V6 engine, in concert with the 8-speed transmission, is particularly adept at maintaining efficiency when settled into a steady rhythm. However, for those who regularly carry heavy loads, tow close to the vehicle’s capacity, or predominantly drive in dense, stop-and-go city traffic, expect figures closer to the 20 MPG city rating, or potentially even slightly below. Aggressive driving, frequent hard acceleration, and high speeds will naturally diminish these numbers. The individual with lighter duties, less frequent heavy hauling, and an appreciation for a smoother, more deliberate driving style is precisely the demographic that will consistently see numbers aligning with or exceeding the EPA estimates. It’s a truck designed for smart driving, not unbridled performance.

How it compares

The 2025 Ram 1500 HFE 2WD 3.6L 6-cyl with its 23 MPG combined rating stands out in a segment often dominated by V8s and boosted six-cylinders. To understand its position, consider its direct rivals configured for maximum efficiency. The Ford F-150 with its 2.7L EcoBoost V6 and 2WD drivetrain typically achieves around 22-23 MPG combined (20-21 city, 26 highway), putting it directly in line with the Ram HFE. The Chevrolet Silverado 1500, when equipped with its 2.7L Turbo High-Output engine and 2WD, often posts similar numbers, around 21 MPG combined (19 city, 22 highway), though some configurations might see 23 MPG combined. The Ram’s achievement is noteworthy because it does so with a naturally aspirated V6. While the turbocharged engines of its competitors offer more torque lower in the rev range, the Ram’s smooth and linear power delivery, combined with its class-leading ride comfort, presents an alternative for those who don’t necessarily need the peak power and torque of forced induction for their daily tasks. The Ram HFE specifically targets the buyer who prioritizes the foundational efficiency of a full-size truck without the added complexity or cost of hybridized powertrains found in other segments.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the easiest ways to ensure your Ram HFE achieves its best fuel economy. Underinflated tires increase rolling resistance, forcing the engine to work harder than necessary. Check your tire pressures regularly, preferably once a month, and adjust them to the manufacturer’s recommended levels found on the door jamb placard.

Smooth acceleration and gentle braking are critical for maximizing the efficiency of the 3.6L V6 and 8-speed automatic. Avoid aggressive starts and hard stops, which consume significantly more fuel. Anticipate traffic and lights, allowing the truck to coast when possible, which keeps the engine in its most efficient operating range.

Consider the weight you’re carrying. The Ram HFE, like any truck, becomes less efficient with additional mass. Remove unnecessary items from the bed or cabin when not in use. Even seemingly small loads can add up, impacting the truck’s ability to maintain its advertised economy.

Aerodynamics play a role, especially on the highway where the 26 MPG figure is observed. If you frequently carry items in the bed, consider a tonneau cover to reduce drag. Open windows at higher speeds can also create significant aerodynamic resistance, so opt for the air conditioning when cruising on the open road.

Regular maintenance, following Ram’s service schedule, ensures all components are operating at their peak. This includes oil changes, air filter replacements, and spark plug checks. A well-maintained engine runs more efficiently, directly contributing to better fuel economy over the life of the vehicle.
