3.0L EcoDiesel vs. 4xe Hybrid: Real-World Fuel Costs for Gladiator (2025)
The Jeep Gladiator is known for its off-road capability, rugged design, and practicality. But when it comes to fuel efficiency, buyers often debate between two powertrain options: the 3.0L EcoDiesel V6 and the upcoming 4xe Hybrid. While Jeep discontinued the EcoDiesel for 2025, used models are still available, and the introduction of a 4xe plug-in hybrid brings new fuel-saving potential.
So, which option saves more money in the long run? Does the EcoDiesel's high MPG offset the cost of diesel fuel, or does the 4xe Hybrid offer better efficiency with electric driving? Let’s dive into real-world fuel costs, MPG comparisons, and long-term ownership expenses.
2025 Jeep Gladiator: Engine Comparison
Before comparing fuel costs, let’s break down the specs of each engine:
| Engine | Horsepower | Torque | Fuel Type | EPA MPG (Est.) | Max Towing |
|---|---|---|---|---|---|
| 3.0L EcoDiesel V6 | 260 hp | 442 lb-ft | Diesel | 22 city / 28 hwy | 6,500 lbs |
| 2.0L 4xe PHEV (Plug-in Hybrid) | ~375 hp | ~470 lb-ft | Gas + Electric | 50+ MPGe (electric), ~20 MPG (gas) | 6,000 lbs |
✔️ The EcoDiesel is best for highway efficiency and long-range travel.
✔️ The 4xe Hybrid offers all-electric city driving but lower towing capacity.
Real-World Fuel Costs: EcoDiesel vs. 4xe Hybrid
Fuel savings depend on driving habits, fuel prices, and efficiency in different conditions. Here’s how the 3.0L EcoDiesel and 4xe Hybrid compare in real-world fuel costs based on 15,000 miles per year.
1. Fuel Costs for the 3.0L EcoDiesel
-
Diesel MPG: ~25 MPG (combined average)
-
Diesel Price (2025 estimate): $4.00 per gallon
-
Annual Diesel Usage: 15,000 miles ÷ 25 MPG = 600 gallons
-
Annual Diesel Cost: 600 × $4.00 = $2,400 per year
2. Fuel Costs for the 4xe Hybrid
-
Electric Range: ~25 miles per charge
-
Gas MPG (after battery depletion): ~20 MPG
-
Electricity Cost: $0.15 per kWh (home charging)
-
Battery Capacity: 17 kWh (~$2.55 per full charge)
Assuming 50% of driving is on electric power and the rest on gas:
-
7,500 electric miles: 7,500 ÷ 25 miles per charge = 300 charges
-
Electric cost: 300 × $2.55 = $765 per year
-
7,500 gas miles: 7,500 ÷ 20 MPG = 375 gallons
-
Gas price: $3.50 per gallon
-
Gas cost: 375 × $3.50 = $1,312 per year
-
Total fuel cost (electric + gas): $765 + $1,312 = $2,077 per year
3. Long-Term Fuel Savings Over 5 Years
| Engine | Annual Fuel Cost | 5-Year Fuel Cost |
|---|---|---|
| 3.0L EcoDiesel | $2,400 | $12,000 |
| 4xe Hybrid | $2,077 | $10,385 |
✔️ The 4xe Hybrid saves ~$1,615 over five years, assuming regular charging.
✔️ The EcoDiesel is better for long highway trips with minimal charging access.
Other Ownership Costs: Maintenance & Repairs
Fuel savings are just one part of the equation. Maintenance costs also impact long-term savings.
| Maintenance Factor | 3.0L EcoDiesel | 4xe Hybrid |
|---|---|---|
| Oil Changes | Expensive (~$120 per change) | Cheaper (~$80 per change) |
| Battery Replacement | No hybrid battery | Expensive (~$6,000+ after 8–10 years) |
| Brake Wear | Standard | Regenerative braking extends brake life |
| Diesel Particulate Filter (DPF) | Requires maintenance | No DPF |
✔️ EcoDiesel requires more expensive maintenance, especially oil changes and emissions system upkeep.
✔️ 4xe Hybrid benefits from regenerative braking, reducing brake wear.
✔️ Battery replacement costs for the 4xe could be high after 8–10 years.
Towing & Performance: Which Engine is Better?
| Category | 3.0L EcoDiesel | 4xe Hybrid |
|---|---|---|
| Max Towing | 6,500 lbs | 6,000 lbs |
| Torque | 442 lb-ft | ~470 lb-ft |
| Best for | Highway towing & efficiency | City driving & light towing |
✔️ The EcoDiesel is better for long highway hauls with higher towing capacity.
✔️ The 4xe Hybrid is better for city commutes with shorter trips and daily charging.
Final Verdict: Which Gladiator Engine Saves You More Money?
🔹 Choose the 3.0L EcoDiesel if:
✔️ You drive long distances or tow frequently.
✔️ You prefer higher highway MPG and better resale value.
✔️ You don’t mind higher maintenance costs for a diesel engine.
🔹 Choose the 4xe Hybrid if:
✔️ You drive mainly in the city and can charge at home.
✔️ You want lower maintenance costs and regenerative braking.
✔️ You prefer eco-friendly, all-electric short trips.
Winner? 💡
➡️ 4xe Hybrid saves more in urban settings with charging access.
➡️ EcoDiesel is still the best for highway MPG and long-haul driving.
