2026 Ram 1500 MPG and Fuel Efficiency by Engine and Trim

Modern truck buyers no longer accept a hard trade-off between capability and running costs. Whether you are hauling to a job site or heading toward the San Bernardino Mountains for the weekend, what a full-size pickup costs to operate matters. For 2026, the Ram 1500 answers that with a rare thing in the truck world: a genuine choice of four gas engines, each tuned for a different balance of efficiency, power, and character.

That choice is the real headline for 2026. The twin-turbo Hurricane inline-six that arrived for 2025 continues in two outputs, the efficient Pentastar V6 remains the mileage leader, and the 5.7L HEMI V8 — dropped for 2025 — is back by popular demand. At Jeep Chrysler Dodge Ram of Ontario, we help shoppers match how they actually drive to the right powertrain. Find us at 1202 Auto Center Dr, Ontario, CA 91761.

2026 Ram 1500 Engine Lineup at a Glance

Every gas engine pairs with an eight-speed automatic transmission. The Pentastar, Hurricane SO, and HEMI can be configured with rear-wheel drive (4×2) or four-wheel drive (4×4); the High-Output Hurricane comes with four-wheel drive.

EPA-Estimated Fuel Economy by Engine and Drivetrain

Here is how the four engines compare on EPA-estimated fuel economy. Use these figures to compare configurations — your actual mileage will depend on how and where you drive.

Figures shown are EPA-estimated for the drivetrain listed. The High-Output Hurricane and the RHO come standard with four-wheel drive; the RHO’s off-road-focused setup rates lowest in the lineup. The HEMI V8 recommends midgrade fuel, and both High-Output Hurricane configurations require premium.

EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.

The Efficiency Leader: 3.6L Pentastar V6

If maximizing gas mileage is your top priority, the 3.6L Pentastar V6 is the engine to choose. It produces 305 horsepower and 269 lb-ft of torque and comes standard with a 48-volt eTorque mild-hybrid system. eTorque replaces the conventional alternator with a belt-driven motor-generator that recovers energy during deceleration and feeds it back to smooth stop-start operation and assist the engine off the line.

• Best-in-lineup efficiency: an EPA-estimated 20 city / 25 highway MPG in 4×2.
• 4×4 available: an EPA-estimated 19 city / 24 highway MPG.
• Best for: daily commuting around Ontario and Corona, light hauling, and buyers who rarely tow heavy.

The Volume Powerhouse: 3.0L Hurricane Standard Output

The standard-output Hurricane is the engine most Ram 1500 buyers who tow will want. Its twin-turbocharged inline-six makes 420 horsepower and 469 lb-ft of torque — more than the outgoing V8 — while still returning strong highway numbers.

• Efficiency for its output: an EPA-estimated 18 city / 25 highway MPG in 4×2; 18 city / 24 highway MPG in 4×4.
• Highway match: ties the V6 at an EPA-estimated 25 highway MPG in 4×2, despite making 115 more horsepower.
• Best for: drivers who tow regularly but still want manageable weekly fuel costs.

The Performance Flagship: 3.0L Hurricane High Output

For maximum power, the high-output Hurricane raises output to 540 horsepower and 521 lb-ft of torque and comes standard on the RHO, Limited, Limited Longhorn, and Tungsten. It is tuned for acceleration rather than maximum efficiency.

• EPA-estimated fuel economy: an EPA-estimated 15 city / 21 highway MPG (4×4) on the Limited, Limited Longhorn, and Tungsten; the off-road RHO rates lower at an EPA-estimated 14 city / 16 highway MPG.
• Best for: buyers who want the quickest, most powerful Ram 1500 and treat fuel economy as a secondary concern.

The Return of the 5.7L HEMI V8

After a one-year absence, the 5.7L HEMI V8 is back for 2026, producing 395 horsepower and 410 lb-ft of torque with eTorque mild-hybrid assist. It is available across most trims for buyers who want the traditional naturally aspirated V8 character and sound.

• EPA-estimated fuel economy: an EPA-estimated 17 city / 22 highway MPG in 4×2 and 16 city / 20 highway MPG in 4×4.
• The trade-off: the HEMI trails the Hurricane engines on efficiency but delivers the V8 experience many truck buyers still prefer.
• Best for: traditionalists who value V8 feel and sound over maximum MPG.

Fuel Tank Sizes and Driving Range

Range depends on both fuel economy and tank capacity. The Ram 1500 offers two tank sizes, letting you tailor range to your typical drives.

• 26-gallon tank (standard): the standard capacity across most configurations.
• 33-gallon tank (available): the larger option for drivers who want to minimize fuel stops on long hauls.

With the 33-gallon tank and an efficient engine, an EPA-estimated highway range can exceed 800 miles on a single fill — enough to bypass local stations entirely on long-distance trips. Range figures use EPA highway estimates and will vary with driving conditions and load.

The Warranty Behind Every Engine

Whichever engine you choose, Ram backs it with segment-leading coverage for 2026:

• Basic limited warranty: 3 years / 36,000 miles.
• Powertrain limited warranty: 10 years / 100,000 miles for the original owner — among the strongest in the full-size truck segment, covering the engine, transmission, transfer case, driveshafts, differentials, and axles.

That decade-long powertrain coverage is a meaningful reason to buy with confidence, regardless of which powertrain fits your driving.
