Ram’s new Hurricane engine is on a power terror, showing up in many Ram 1500 models for 2025, including the high-powered RHO. This new engine is smaller by two cylinders than the outgoing Hemi V8, which should translate to better fuel efficiency, but that might not be the case for every version of this new engine.

Power isn’t an issue with the new Ram Hurricane Engine

We’ll certainly miss the naturally aspirated Hemi V8 engines, especially the useful 5.7-liter model. This engine produced 395 horsepower and 410 lb-ft of torque, but the race for more power means these figures aren’t enough.

The new 3.0-liter twin-turbocharged inline 6-cylinder engine delivers the goods with 420 horsepower and 469 lb-ft of torque. These figures handily beat the 5.7-liter Hemi, effectively putting the old V8 out to pasture.  In high-output versions, the Hurricane engine produces 540 horsepower and 521 lb-ft of torque for the new Ram 1500 RHO, which replaces the TRX.

How efficient is this new Ram 1500 engine?

2025 Ram 1500 pickup trucks equipped with the standard-output Hurricane engine and RWD return 18 city/25 hwy mpg. These are good figures compared to the 5.7-liter Hemi, which delivered 18 city/23 hwy mpg. The Hurricane is more efficient, but you might expect much better figures from two fewer cylinders and forced induction.

Ram trucks on the higher end of the power spectrum aren’t quite as fortunate. The high-output Hurricane engine only comes with 4WD, instantly reducing fuel mileage. These higher powered models deliver 15 city/21 hwy mpg. This gives us figures that take things backward for Ram. The 4WD Hemi Rams produced 18 city/22 hwy mpg, easily besting the new 6-cylinder engine.

What’s the most efficient 2025 Ram 1500?

Although most automakers switching from V8s to turbo-6s see impressive fuel mileage improvements, the Ram 1500 lineup tells a different story. If you want the most efficient half-ton Ram truck in 2025, it’s the HFE model with the base 3.6-liter Pentastar V6 engine and RWD. This powertrain returns 20 city/26 hwy mpg, besting the new standard-output Hurricane engine.

Could Ram improve efficiency soon?

2025 will be the first model year for the Hurricane engine to replace the Hemi V8 in Ram trucks. Going forward, adding hybrid technology to these trucks could improve fuel mileage while maintaining or improving power. Ram trucks have had a mild-hybrid system available for a few years. It could play a part, but a traditional hybrid or PHEV version of the Ram 1500 could dramatically improve efficiency.

Of course, with the Ramcharger and REV models on the horizon, traditional hybrid layouts might not be in the cards for the Hurricane engine.
