Stellantis Hurricane4 Engine Reveal

[HemiBenny]

This is the engine that should be in the Miata!

Let’s just leave Mazda and the Miata out of this!

Mazda engineering vs Stellantis engineering? Mazda all day long.

As for Stellantis? I’ve always had good luck with my Chrysler products, but I wouldn’t touch a Stellantis version with a 10’ pole right now. Of course, I wouldn’t touch a Ford, GM, Hyundai/Kia, or certain Toyota products with one either.

I’ll be interested in watching the reliability on this Hurricane engine. Hopefully, it doesn’t die a quick death like hurricanes do once they hit the ground.

This would matter if the rest followed. A Grand Cherokee will still be north of 4000lbs with this thing, and they'll have to be hauled by it.


GOD FORBID !!!
Miatas are precious and have to last. Don't doom them.

Sorry guys….I don’t know much about recent Stellantis products. I’m smart enough to have never purchased one.

Gonna be a hard pass from me. Just can't get past a 4 banger moving 5000Lbs+.

From hellcat v8's to buzzy 4 bangers.... Ugh

Outdated thinking.

I'd go back to that small displacement 2.3L Turbo in a heartbeat if they would bring the hybrid here and had the onboard 7.2kw inverter.

And no, it wasn't wound out or struggling to pull the weight. We normally run about 65-70 in 8th gear at something like 22-2500 RPM.

Properly built and implemented small turbo motors can do the work. I never worried about the motor in my truck. Only thing I was going to plan on doing at 100k is to walnut blast the intake valves.

I know, I still don't like it

I'll take mine V8 please.

A GC is currently being "hauled" by a NA V6 (Pentastar) with much less peak HP and Tq, and much less power under the curve. The pentastar even powers the heavier ram 1500 more than adequately for daily driving.

Of all the reasons to worry about purchasing this engine where previously the 3.6 was used, "engine power" is not the concern.

No that more accurately would be Peppy Pentastar minivan moovers to buzzy 4 banger exploders

Me I'd take a good ole 318 in Magnum form

I had a Dakota with a 318 V8 and the MOPAR premium gas ecu. Mt turbo 4 Colorado would leave that V8 Dodge 100 yards behind in the quarter mile.

 

[ARCOgraphite]

Different engine. The Hurricane4 as discussed in this thread is a new engine and not the same as the GME4T/Hurricane EVO family.

Of course. But just commenting on the underdeveloped engine management and other uncomfortable issues. Maybe Stellantis made them get their "stuff" together. Those Dutch can be strict - even if they are known to swim nekkid.

Yeah but a modernized 318 would be smooth and easy. I don't see any of my fellow citizens jumping on their engines - NONE - other than Bruhs with dirty diesel coal rollers.

Me, if I am up front at a light wid some schmoe in the left lane - it's all Brittany Force cuttin' a light and gone!
70 year's old, boy needs a thrill ...

No, no, no! Wankel.

 

[Hohn]

Yeah I think it is probably super useful to be able to vary the flow rate through the engine on command instead of being tied to engine rpm.

We went to electric cooling fans ages ago for a good reason. Seems to me that an electric water pump (especially if it's modern brushless DC) makes a ton of sense to help engines warm up faster and have less parasitic drag.

Are there any engines that include an electric sprayer to prelube the engine valvetrain before dry starts? Seems like a no brainer.

I rather like the pentastar... when mated to a proper (8 speed) transmission. I've owned 2 of them. In the grand caravan though it's just blah but the 62TE is a joke of a transmission, just like the 545RFE/65RFE.

It's not always about being the fastest.... Sometimes you just gotta sound good and man those magnums sounded good!

No, because the valve train isn't super sensitive to oil delay. Not the way rod bearings are.

Interesting, I was thinking more in terms of the timing hardware. I just had my chain replaced.

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.

And much less cubic centimeters. And two less cylinders.
Drove two identical Jaguars back in Europe this summer, one with a 2l turbo something 4cyl, the other with a six cyl diesel. Same power and close torque numbers, different worlds.

Yep, I love the Pentastar. It's great with the auto....Love it in my Gladiator, but I love it also with the manual in my JL. It's a great match to both. Funny, though, it is generally more fuel efficient in the heavier Gladiator with the auto than the lighter JL with the manual.

Interesting note....On our trip to Moab and back last week, on the highway between 75 and 80mph the Gladiator and my brother's Colorado ZR2 Bison achieved nearly identical fuel economy. The Colorado was able to hold a higher gear than the Gladiator, too. Both trucks were running 35" tires. The Gladiator has a 4.10 axle ratio and the Colorado is a bit taller at 3.42.

So the old V6 performed pretty well compared to the 2.7 turbo. But at 80mph with a 40mph headwind, it had to fight and run at higher rpm. The torque from that 2.7 enabled the Colorado to not work as hard. I was carrying probably 300lbs more load, though, too.

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.

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.
