Stellantis Hurricane4 Engine Reveal

[hemioiler]

It will be irrelevant indeed if they manage to pair that beautiful curve with refinement, smoothness and balance close to something with more cylinders.
I don't know how the previous 6 cylinder behaved, so - maybe it will be a tie or win by omission.
All I know is that in the Jaguar's case the 6 was smashing the 4 cyl in the ground like slamming a kitten in a telephone pole. And Jaguar is not exactly known for a lack of refinement. Noise, vibrations, huffing and puffing - you name it, the 4 cyl had it all. It was also more powerful and almost as torquey and so on and so on. Both cars were great and very fast. Same cars, similar trim, two model years difference, the diesel was the older one.

But again - in Stellantis' case, if the existing V6 was unrefined to begin with - sure, the 4 pot could be the thing.

The pentastar and hemi have both been on wards 10 best engine list for years. The hurricane inline 6 is incredibly smooth. Comparing this new hurricane to other stuff you have driven isn't going to prove anything one way or the other. I'd suggest waiting for it to arrive before writing it off.

For actual primary cooling pump, Prius has had electric water pump since day 1.

Not on a 2nd gen-- the electric pump was for the inverter coolant loop. There was still a belt-driven engine coolant pump.

I owned the pentastar in my 2012 grand cherokee for 5 years, it was/is a great engine but like you I felt it was let down by the 5 speed mercedes transmission it was paired to, or maybe transmission tuning was just bad. When I used gear limiter and held the gears longer it did great, but without that it wanted to up shift super fast into 3rd and then it was like hitting the brakes lol. I test drove the 2014+ model with the ZF 8 speed and it was a much nicer experience.

I know the bitog FCA haters aren't going to like this but all that GC cost me in 5 years was regular maintenance and an $80 brake pedal sensor, sold it at 150k KMs to get my current truck to use as a bigger tow vehicle, otherwise would probably still be driving it.

Yeah the transmission programming is all over the place I've noticed. The 5.7+NAG1 combo in our challenger is wonderful. Nice firm shifts, doesn't hunt for gears, pulls like a freight train, I cracked off a 5.8 0-60 in it the other day with 161k miles on the clock. But the V6 Durango? Totally different transmission feel.

And my mother's 200 S... Identical drivetrain to our Grand Caravan, but for whatever reason the transmission programming is wildly different and so much better. It has nice firm shifts, where the van is the definition of slush box.

Unrefined? In terms of NVH, It is smooth as silk and sounds much better than any 4 I have ever heard.

I currently am driving an Avis rental. It's a 2025 Explorer. When I arrived at the airport rental counter a couple of days ago to pick up the car I reserved, they said it wasn't available and the choices I had were a Durango or the Explorer. Surprisingly this Explorer is the Platinum version with AWD, I was expecting a base model. This is a nice car and at first I thought it had an Ecoboost V6 under the hood. The sound though wasn't V6, popped the hood and there's a 4 banger.
I've never driven a 4 banger that pulls like this one. In sport mode the low and midrange torque this thing has is impressive. Also, Ford has dialed out a lot of the NVH I would expect out of a 4 cylinder, just cruising around it's a very nice ride. Looked it up and apparently this is a 300 horsepower 2.3 liter engine.
If this 2.3 Ecoboost is what modern 4 cylinder engines are like, the Hurricane should be a good Pentastar replacement.

These fours are indeed powerhouses and I would have no trouble owning one if.....and a big if, they show to be durable and long lasting. I see Pentastars regularly with well over 200k on them. A close friend has a Jeep with one with 270,000 trouble free miles and he keeps racking them up. Will these little turbos do that? Time will tell. I hope so.

I've got 3 Pentastars in 3 Jeeps (my two and my daughter's). They have about 270,000 miles among them. All 3 with zero issues. One is an E-torque version, too, that gets 90% short trips. It is at 100k.

The Pentastars have been hard to replace because they are cheaper to build than the turbos and when they have a problem, generally less expensive to fix. They are known to have among the lowest warranty claim costs in the industry. That's money in the corporate bank account. Ford, when they went almost completely Ecoboost, had a year where they spent more than anyone on warranty claims. Reportedly, it was because of the turbo engines. But that may have been teething pain. They have seemed to get that well under control. Again, time will tell. But I am sure they wouldn't be so popular among manufacturers if they were costing them an arm and a leg with warranty. So I think they will be a good bet. So far so good for the previous 2.0 from Jeep. I haven't heard of problems with them in the Jeep community as of yet. And some are piling up the mileage by now.

They are still pounding me with warranty offers for my 2020 PUG - but hopefully - I won’t see more than that oil cooler thing in the next few years …
(no issues so far) …

Been saying that ever since I bought the Ranger back in 2020. The 2.3L punches well above its weight. It is a little more powerful in the Explorer and I'm sure they have it smoothed out some, but it is a fantastic little motor.

My son has the I4T Mustang - it will join traffic with ease … !

Irrelevant. Look at the dyno charts, this turbo is putting out more power literally everywhere in the rpm band vs the engine its designed to replace.

Show me 1/8th throttle opening torque. The sixer I bet would kill an off boost 2 liter Turd Broh

Problem with dyno it's WOT torque charting. Not how you drive unless "motorsports"

There is practically no "off boost" with these engines if designed correctly. I occasionally drive a couple cars with BMW B46 engine with 255 hp (turbo 4) and it blows away the Pentastar 3.6 in reality in every facet including part throttle power delivery.

It's a VGT turbo, waiting to get over 2,000 RPM probably. Hybridization, either of the turbo itself or the powertrain, fixes this. But of course Stellantis is going a different route. I'm sure it will be fine for the average driver. It's not the 3.6 was so awesome.

I think The Drive is the only outlet to describe it as laggy from the reviews I have watched and read. I think most reviewer say it is fine. Which is about all we can expect from this engine in something the size of a Grand Cherokee. I will probably be curious enough to go test drive a Grand Cherokee L at some point in the near future with this engine and find out for myself.

 

[Number_35]

Yep. I was interested in a newer rogue to replace my 2018 with the indestructible 2.5. Then I joined a forum and realized that their 1.5L turbo charged sewing machine engines were locking up and self destructing.

Is the Nissan 1.5T equipped with variable-compression technology?

It seems like a lot of added complexity for minimal real-world gain.

The Drive Article

Looks like it is quite an interesting engine. I'm thinking I will be in the market for a 3-Row vehicle pretty soon so I'm interested to see how it performs in the Grand Cherokee L.

Max Horsepower: 324
Max Torque: 332ft-lbs
Estimate Grand Cherokee MPG: 21/23/27

Some listed Features
- Variable Geometry Turbo
- Turbulent Jet Injection in addition to 1 regular spark plug in the combustion chamber.
- Port and Direct fuel inject
- Electric water pump
- Block design appears to be an open deck design. But with the thickness of the cylinder walls it is probably closer to a closed deck than an open deck block.

Power density is 26% higher than the Hellcat Redeye V8 at 126hp/L.

You lost me at the variable geometry turbo. That word variable pertaining to turbos, displacement and compression scare me. My wife's Nissan uses that VC_T engine and to me it just leaves too many variables that can and possibly will go wrong.

VGTs have been around for ages in diesel applications. They are becoming more common in gasoline applications. I doubt the VGT is going to be the limiting factor from a reliability standpoint on this engine.

 

[rijndael]

I'd rather have an electric turbo than a variable turbo.
