When comparing the Ram RHO vs. TRX, it’s clear that neither of these Ram 1500 trim levels tolerates weak airflow. Both cram as many air molecules as possible into their engines in order to generate their extreme specs. The air induction method and cylinder count/layout are what differ.
Firing the first volley is the TRX, as it entered the market earlier as a way to get Hellcat power in a full-size truck. A 6.2-liter supercharged HEMI V-8 is that Hellcat power. For the Ram 1500 TRX, the sixth circle opens, and this engine crawls out with 702 horsepower for a 4.5-second 0-60 mph time.
While the supercharged TRX is like an artillery bombardment, the twin-turbo, inline-six-powered RHO is akin to a sniper taking direct aim: it uses its 540-horsepower output with more precision, achieving a 4.6-second 0-60 mph time.
For more speed, see the Ram 1500 REV electric truck specs: They include an even faster 4.4-second 0-60 mph time with minimal noise.
On the topic of noise, the TRX is the polar opposite of an EV. It screams, roars, and shakes the ground as it shotguns fuel. This melody alone can be the determining factor; the Ram 1500 RHO still rumbles and blasts you with high-decibel glory, but with a sportier, smoother tone.
If you were to keep your foot down past 60 mph, the RHO would almost be the faster truck: It posts a 13.1-second quarter-mile time, which is only 0.2 seconds off of the Ram 1500 TRX pace.
The topic of efficiency is another major difference (the RHO wins), but neither truck is an efficiency-oriented vehicle (see a Pentastar-powered Ram 1500 for that).

Both of these pickups take truck stuff to the extreme. By “truck stuff,” we mean off-roading, and both choices here are kitted to dominate dunes, rocky trails, and pretty much anything else that a set of 35-inch tires can bite into.
The upgrades are very similar, with mostly minor differences to touch on. For example, both offer 18-inch beadlock-ready wheels and 35-inch all-terrain tires, but there’s something major to keep in mind: As seen above, the 2024 Ram 1500 TRX has a $47,630-higher starting MSRP than the 2025 Ram 1500 RHO.1 An almost identical quarter mile with similar off-road ease and a lower price makes the RHO more than just a worthy replacement for the TRX – it makes it the next chapter in the history of factory-built lifted Ram 1500 trucks.
Plus, the RHO is a part of the redesigned next-generation Ram lineup (which can be further explored in our Ram 1500 vs. 2500 guide), and as such, it has next-generation interior features. The TRX, without a doubt, is well-equipped, but the RHO is a bit more modern.
Both trucks here offer features like a 19-speaker Harman Kardon® sound system, leather upholstery, a digital rearview mirror, a Head-Up Display, Pedestrian Emergency Braking, and an electronic-locking rear differential, but the Ram 1500 RHO goes further with 2025 features like dual wireless charging pads, a Hands-Free Active Driving Assist, and a 12-way power driver’s seat. The TRX doesn’t offer those final two features and has an eight-way power driver’s seat.
Thanks to the 2025 updates, the Ram 1500 vs. Ford F-150 favors the Ram truck more than ever, though the violently supercharged Ram 1500 TRX is still quite the luxurious truck.

The Ram RHO has a much lower starting price, an almost identical quarter-mile time, and better MPG ratings than the Ram TRX, which can make it clearly the better truck. However, the Ram TRX is irreplaceable in terms of brutality, and if you find a supercharged scream with 702 horsepower from a V-8 to be the best thing a vehicle can offer, then the TRX is for you.
The “RHO” name doesn’t have an official brand-confirmed meaning, but many consider it to mean “Ram Hi-Output” because of the high-output Hurricane twin-turbo engine that it gets its power from. RHO can also be interpreted as “Rhino,” which is an apt comparison: both a rhino and an RHO are powerhouses who charge forward with massive strength.
The Ram brand has replaced the TRX with the RHO: a twin-turbo, six-cylinder alternative that has a similar quarter-mile time and a significantly lower starting price than the 2024 Ram 1500 TRX. This comes in conjunction with further CDJR-family evolutions, such as the gas-powered Dodge Charger sedan being replaced with the two-door Dodge Charger EV.
