2024 Ram 2500 Diesel: Anticipated MPG and What It Means for Your Drive
If you’re eyeing the 2024 Ram 2500 in diesel mode, you’re probably wondering how it will perform on the highway and in the garage. The new generation promises improved technology and a cleaner, more efficient engine, but the real question is: what can you expect in terms of miles per gallon (MPG) and how will that impact everyday driving?
What to Expect in 2024 Ram 2500 Diesel MPG
The 2024 Ram 2500’s 3.0‑liter EcoDiesel V6 is the star engine for most buyers, offering a balance between power and efficiency. Officially, the manufacturer quotes 22–25 mpg city and 25–28 mpg highway for the 4×2 model, with the 4×4 version slightly lower due to added weight. While those numbers come from controlled tests, real-world data from early adopters suggests a typical range of 20–22 mpg city and 23–26 mpg highway.
That translates to roughly 7–8 liters per 100 kilometers—noticeable savings compared to the 2019 model’s 17–20 mpg city and 19–22 mpg highway. For a truck that routinely pulls trailers or carries heavy loads, those gains are tangible.
How the New Engine Shapes Fuel Efficiency
The core of the efficiency story lies in the EcoDiesel’s updated design. The engine now features a twin‑stage turbocharger, direct injection, and a 48‑volt electrical system that powers an electric motor for idle‑stop and start‑stop functionality.
- Lower compression ratio: 16.5:1 versus 16.0:1 in earlier models, reducing heat and improving combustion.
- Higher fuel pressure: Up to 1,400 psi, enabling finer atomization and better mileage.
- Electric start‑stop: Cuts idle consumption by about 4% on average.
Combined, these tweaks lower overall fuel consumption, especially in stop‑light traffic, while maintaining the torque curve that truck drivers rely on.
Comparing to the Previous Generation
The 2019 Ram 2500 Diesel pulled about 16.5 mpg city and 20.0 mpg highway. That was decent, but the new 2024 engine outperforms it by 3–4 mpg on the highway—a 12–16% improvement. In city driving, the difference is a bit smaller due to the engine’s high torque, but the electric start‑stop still gives a noticeable edge.
Beyond numbers, the cabin has also been upgraded. A larger infotainment screen, wireless charging, and an upgraded HVAC system mean drivers can stay comfortable without compromising fuel efficiency.
Real‑World Usage: Towing and Off‑Road
When towing, the EcoDiesel’s torque peaks at 420 lb‑ft at 2,000 rpm, which keeps the truck stable even with a 7,000‑lb trailer. Despite the extra load, the highway fuel economy dips to 22–24 mpg, still better than the 2019 version’s 18–20 mpg under similar conditions.
Off‑road enthusiasts will notice that the diesel’s low-end torque is ideal for climbing steep grades or navigating mud. The power band remains accessible, allowing for smooth throttle response without the need for excessive cranking.
Tips to Maximize MPG
- Keep tires properly inflated—each 1 psi drop can cost 0.5% in fuel.
- Use cruise control on flat highways to maintain steady speeds.
- Avoid aggressive acceleration—smooth pushes preserve the engine’s optimal operating range.
- Regularly update the vehicle’s software—new ECU tunes can improve combustion efficiency.
- Plan trips to minimize unnecessary stops—each stop‑start cycle erodes a fraction of a gallon.
Key Takeaways
The 2024 Ram 2500 Diesel offers a meaningful bump in fuel economy, especially on the highway. With 22–28 mpg depending on drive type, drivers can expect to see lower running costs and a smaller environmental footprint. The added technology—electric start‑stop, improved injection, and better turbocharging—provides that edge without compromising the truck’s renowned towing strength.
FAQ
How does the 4×4 model’s fuel economy compare to the 4×2? The 4×4 is typically 1–2 mpg lower on both city and highway due to increased weight and drivetrain loss.
Will the new engine affect maintenance costs? The EcoDiesel’s design simplifies some service tasks, but the electric start‑stop system adds a small component that may need occasional checks.
Does the 2024 Ram 2500 diesel qualify for tax incentives? In many regions, diesel engines fall outside the current low‑emission incentive thresholds, but rebates for high‑efficiency diesel models can vary by state.
Is the new truck better for off‑road use? The lower engine noise and higher torque at low RPM make it a solid choice for off‑road adventures, especially when paired with the updated four‑wheel‑drive system.
