Secrets Behind The Dodge Ram 1500 Hemi

Back where it belongs. Plenty of truck folks still call it the Dodge Ram 1500 Hemi, a habit that stuck around long after Ram split off as its own brand in 2009, and honestly, nobody at the sales counter minds. What matters is the V-8 under the hood. It vanished for a year, but Ram listened to buyers.

Gone for a Year, Then Back

The 5.7-liter Hemi landed in the Ram in 2003 and became the exact engine half the job sites in America seemed to idle on. For 2025, Ram went six-cylinder across the board, leaning into turbos, efficiency targets, and the modern playbook.

Truck buyers were having none of it. The pushback got loud enough that the 5.7 came back, landing in trims from the Tradesman up to Limited Longhorn. Ram’s own brand boss even admitted dropping the V-8 was a mistake.

Power, Torque, and eTorque Assist

The returning Hemi brings back familiar output figures alongside its eight-speed automatic, with mild-hybrid hardware riding along as standard:

• Output: 395 horsepower and 410 pound-feet of torque
• Transmission: TorqueFlite eight-speed automatic
• Hybrid assist: 48-volt eTorque with a 430 watt-hour battery behind the rear seat
• Efficiency tech: variable cam timing paired with cylinder deactivation

That 48-volt eTorque setup smooths out stop-start driving and fills in low-end grunt off the line. You feel its help more than you notice it, delivering up to 130 pound-feet of short-burst assistance when accelerating.

What It Pulls at the Hitch

Properly equipped, a Hemi-powered Ram 1500 pulls more than 11,000 pounds. While the twin-turbo Hurricane SO edges it out by a few hundred pounds on paper, behind a 30-foot camper that minor gap is a rounding error.

Against the 540-horsepower Hurricane HO, the V-8 wins at the hitch outright. That is by design: the HO six-cylinder is tuned for speed, whereas the Hemi’s torque curve is built for steady, long pulls up steep inclines with heavy iron behind you. Boat, horse trailer, or skid steer; it doesn’t care.

Comparing the Engines

• 5.7-liter Hemi V-8 eTorque: 395 horsepower / 410 lb-ft torque | Max Towing: 11,000+ lbs
• 3.0-liter Hurricane SO: 420 horsepower / 469 lb-ft torque | Max Towing: 11,530 lbs
• 3.0-liter Hurricane HO: 540 horsepower / 521 lb-ft torque | Max Towing: 9,480 lbs

A Growing Hemi Lineup

The 5.7-liter isn’t the only Hemi on the menu anymore. Four versions now wear the badge:

• 5.7-liter with eTorque: Mainstream choice from Tradesman through Limited Longhorn.
• 5.7-liter without eTorque: Exclusive to Rumble Bee for an old-school setup.
• 6.4-liter “392”: Packing 470 horsepower, marking the first time this engine sits in a Ram 1500.
• 6.2-liter supercharged V-8: Cranking out 777 horsepower and 680 pound-feet of torque in the TRX SRT and Rumble Bee SRT.

That Rumble Bee name carries history, hailing back to the short-bed 2004 and 2005 Dodge Ram 1500 models that still turn heads at car shows.

That Cold-Start Sound

Spec sheets can’t capture what happens when you turn the key. When the V-8 returned, Ram fitted these trucks with a performance exhaust as standard and placed a “Symbol of Protest” badge on the fender, a cheeky nod to vocal owners who demanded its return. Some folks buy the Hemi for heavy towing, but plenty buy it for that cold-start rumble on a January morning that wakes up the whole street.

Frequently Asked Questions

Q: Is the Hemi a hybrid now?

A: Sort of. The mainstream 5.7 uses eTorque, a 48-volt mild-hybrid system with a small battery behind the rear seat. It won’t move the truck on electric power alone. The one exception is the Rumble Bee’s 5.7, which skips eTorque entirely.

Q: Hemi or Hurricane, which should I get?

A: Depends on what you’re after. Towing is close to a wash against the SO, so it really comes down to character: V-8 rumble and that familiar feel, or more peak power from a twin-turbo six. Drive both. Seriously.

Q: Is the TRX engine a Hemi too?

A: Yep. A 6.2-liter supercharged Hemi rated at 777 horsepower, shared with the Rumble Bee SRT and a very different animal from the 5.7.
