Rho, as I’m sure you all know, is the 17th letter of the Greek alphabet. Stylized as RHO, it’s also the designator for this Ram 1500 4x4 package.

Rho is also used in the sciences to denote densities such as mass density or air density. Perhaps Ram used this designator to allude to the twin-turbocharged, 3.0-liter inline-six under the hood, which cranks out more than 500 horsepower and results in what Ram claims is the most power per dollar of any truck on the market.

Rho is also used to denote the amount of electrical resistance of a specific component of an electrical system, perhaps Ram’s clever allusion to the RHO’s Bilstein-based off-road suspension package resisting the many heaves and bumps of a rough, rocky trail or the washboards of a dry desert road.

But rho can also represent a concept in economic theory that correlates the rate of change of a fixed portfolio of securities with respect to prevailing interest rates. Perhaps a subtle nod to Ram’s current offer of a generous $2000 total cash allowance and 3.9% APR financing for 72 months* for qualified buyers (offer ends 6/2/25. Act now!).

Oh, maybe the Ram 1500 RHO is a… hang on… being told that Stellantis says the RHO doesn’t actually stand for anything. Okay never mind that whole intro. It was just something that sounded cool, I guess?

The most likely scenario comes from the internal codename for the 3.0-liter, 540-horsepower pressurized straight six: Rhino. The horned beast on the console-mounted VIN tag would lend some credibility here, although there’s no official confirmation. And now it’s called the “Hurricane,” so who knows.

And all this really fits in well with the overall character of the truck, which is a lot of knobs going all the way to 11. The 1500 RHO is the vehicular equivalent of a guy in a tank top with sunglasses on the back of his head. When he walks up to you, you think he might be a really cool dude or he might be a real pain in the ass, but one thing you know beyond a shadow of a doubt is he’s going to be A LOT.

Indeed, this truck is A LOT. Some of it good, some of it, I dunno, good-adjacent?

Like, good but in the wrong context? For example, this thing has launch control. This truck. Has launch control. It goes zero to 60 in 4.6 seconds. It’s a truck. A truck. I guess for when you need to be the first dad at the boat ramp on Memorial Day?

It’s also got Stellantis’ hands-free driver assist that pilots the vehicle on limited access highways as well as GM’s Supercruise. But unlike GM’s system, this implementation doesn’t function while towing. So if you want to RHO your boat to the shore, you’ll have to be in command the whole way there.

Man, I don’t even know anymore. I’m just so tired and this truck is just so much. I just want it to do truck stuff, and it has all the ingredients to do that well but it keeps showing up to my peaceful cookout and yelling, “HELL YEAH, PARTY!” and tossing cans of beer and Monster Energy to everyone and putting on some Molly Hatchet and, oh my God, can’t I just enjoy a hotd og with my family!?

Look, there are some cool ideas here. I love Ram’s implementation of their rear bed assist step, which is manually deployed and decoupled from the tailgate, meaning it can be used even when the tailgate is up, unlike, say, Ford’s rear step. I also like the amount of connectivity, with its USB-A and USB-C ports, as well as an HDMI port prominently located on the dash.

The max tow capacity of 8380 pounds seems a bit low in a marketplace where 10,000 or even 12,000-plus pounds are more the standard for a half-ton pickup, but I get the feeling the focus here was more on desert carving and rock crawling than towing with the fancy remote-reservoir shocks and all.

Although the main implementation for this $88,100-as-equipped truck will likely be more of the hard parking/mall cruising variety, the serious off-roaders will certainly appreciate the massaging seats.

Really, I guess I’m just bitter that a company that clearly has cool people working there–the kind that implement things like launch control and trick suspension systems–doesn’t have a proper sports car or even a proper muscle car in the lineup to implement some of those trick features on and instead they have to use a VERY EXTREME® truck as their palette.

The RHO has cool bits, and the basic truck is competent and substantial feeling. This particular execution is a bit … much, but I can’t fault the enthusiasm of its creators.

Can we get a Hurricane powered Charger soon?  With the Hemi, Hellcat, in everything they make let's see the  Hurricane power something useful like a small wagon or hatchback.

I would be wary of anything Hurricane powered after reading the, uh, "glowing" reviews by Chrysler techs.

Apparently that new Hurrican engine is a disaster, according to Chrysler techs on Reddit:

  • "Hey guys, For all the techs at the Chrysler dealers, be aware of the crap going on with the twin turbo Hurricane engines in the DTs. We have had two in a row now with coolant leaks right off the transporter. Found clamps left in tanged open positions, not in the untanged tight set. These are on bypass and heater hoses on left side of engine. Coolant was spraying all over when hot andn running. Took a lil bit of bright light and good visual inspection to actually see down to the lower clamps where the coolant was actually coming from. Guess the raise the Union guys got doesn't include proper assembly, another raise is needed for that. Thought vehicles were run up and inspected before ship out. Lmfao!! Unbelievable!! Retirement cant come soon enough for me."
  • "We have had 2 of those at our dealership. The hurricane is a "natural disaster." Thermostats sticking and cooking the engine as well. We have another HO hurricane that keeps losing oil pressure from a suspected self deleted piston sprayer/cooling jet. Fun times. We're gonna miss the almighty Hemi, sure the lifters eat cams, manifolds, and whatnot but that engine was tried and proven. Gone are the days of reliability. Note to add: the manufacturer specifies that the motor does not turn on the cooling fan until the engine temp hits 235. That info is STAR verified with the vehicle tha5s dropping oil pressure at 14 psi."
  • "The Hurricane blows. They have the name right. Most of ours on lot run rough on start then almost miraculously clear up setting no fault codes. Then runs rough again. And repeat. Had another brand new one off the truck with constant rough run with coil control circuit fault stored. Had to manipulate harness and found high resistance in the engine wiring when manipulating. Had to order a complete new harness. Unbelievable. My previous student, now an awesome line tech, had one in a Wagoner at 8k destroy a catalytic converter. I'm not sure of where the misfire came from. I might ask him tomorrow."
  • "To give a little background, Stellantis laid off a large part of their engine development team when they had just started designing this engine. The high output version of this engine loves to grenade itself. Get ready folks, you're going to see a lot of these things come back with engine problems. And don't even get me started on their new turbo inline 4 with 2 sets of spark plugs and 2 sets of injectors."
  • "And everyone likes to E36 M3 all over the mighty 3.6L. They made over 10 million of those and sure some of them break but, percentage wise, the Pentastar is a solid engine. The Hurricane lives up to it's name as a disaster. Plastic thermostat? What could possibly go wrong? If a Wagoneer isn't being towed in it's because the tow truck didn't get there yet. The 1500s are dropping like flies too. As an added bonus, they throw in a TCM that might last 5000 miles before it dies. We see a lot with less than 500 miles, can't turn the ignition off, kills both batteries and then you have to battle the powertrain center for a valve body that they know is garbage."

Dang. That's not exactly confidence-inspiring.

Yeah I read this a few months ago. It does make me wonder how many of those things are easily solvable build/assembler issues and how many are inherent design flaws. Is this a case of "Don't buy a Hurricane" or "Don't buy an early Hurricane"?

Fingers crossed for the latter of the two, because I think the Hurricane is pretty neat (on paper, at least).

Yikes! Hopefully those are ironed out in the next MY and warranties are extended to early owners. For what it's worth, my last SUV/CUV was a Jeep Cherokee Trailhawk V6. I sold it at 100k and had done some repairs (as befitting a 100k-mile vehicle that has seen off-road use), but it always ran perfectly.

It's just a 5.7 Hemi swap away from being a good truck.

I mean, I'd be leery of any products from a company in a financial death spiral that started even before the current economic shakeup and who's current big plan for salvation is to dust off an engine design that was notorious for chewing up valvetrain at low miles and they were being fined by the government over for how high it's emissions were.

I like that one of those techs uses, "E36 M3" as a verb.

The move away from a V8 is problematic - even if this brand didn't tie its entire identity to large American V8s... and they did.

Trucks like this are an emotional purchase.  No one needs one of these.  When we buy one of these, the part of our brain that never evolved passed neanderthal is in charge.  And that presents a problem for the intellectual argument that this inline 6 should be better than the V8.  Neanderthals aren't listening to anything other than the sound of the motor.  And this one doesn't sound like it should.
