The Ram 1500 pickups are getting a refresh for the 2025 model year. While there’s plenty to be excited about for this refresh, the most notable change will be removing the legendary 5.7-liter Hemi V8 engine, which has been powering these pickups for over 20 years. The replacement? Stellantis’ new twin-turbocharged 3.0-liter Hurricane inline-six engines, which in some configurations are more powerful and efficient than the Hemi, though it doesn’t sound as great.
2025 Ram 1500 Engines: What To Expect
According to 5thGenRams, Ram will call the Hurrican engine the Straight-Six Turbo (SST) engine. In the late 90s, the SST moniker was also used for a particular version of the Dodge Ram pickup dubbed the Super Sport /Truck (SS/T). While Ram or the U.S. Environmental Protection Agency (EPA) have yet to release the official MPG numbers for the new engine, we don’t have to look far to understand what to expect. The engine is already in use in the Ram 1500‘s close relative, the Jeep Grand Wagoneer / Wagoneer and that has about a 1 or 2 mpg difference from the Ram pickup; in the Grand Wagoneer, that comes to 17 mpg combined with 14 in the city and 20 on the highway.
As for the fuel type, Ram’s SST engine can run on the same fuel as the Hemi, which means 87-octane without issue, though 89-octane provides the full power the twin-turbocharged Hurricane engine has to offer. The standard output (S/O) 89-octane can give the pickup 420 horsepower and 469 lb-ft of torque. That engine will be available as a $2,695 option for the Tradesman and Big Horn (Lone Star) trims. Meanwhile, it’s standard on the Rebel and Laramie. The pickups will also have access to the high-output (H/O) SST engine, which Ram requires the use of 91-octane fuel.
The new Ram SST H/O engine can produce 540 horsepower and 521 lb-ft of torque on 91-octane fuel. That engine will be standard on models like the Limited, Limited Longhorn, and Tungsten, though it is not available for other trims. Another thing to note is that the H/O option won’t provide the best towing. The S/O model will be the one to set the bar for the refreshed Ram 1500 pickups, with a maximum towing capacity of 11,560 lbs on specific models, compared to the H/O’s maximum towing of 10,740 lbs.
Finally, the S/O also provides a higher maximum payload capacity for the Tradesman and Big Horn (Lone Star) models, as that engine can be equipped to have a maximum payload of 1,910 lbs. By comparison, the H/O only has 1,370 lbs. However, if you’re looking for even more capacity, the standard 3.6-liter Pentastar V6 with eTorque mild-hybrid system on Tradesman and Big Horn (Lone Star) will be the way to go, with a maximum payload of 2,300 lbs.
