My opinion is Stellantis should have pursued an I5 instead of I6. One large advantage is the main bearing support on a 5 is greater than a 6 because they need the same number of mains. Get a beefy 3 litre I5 block and twin turbo’s at the higher psi and could have a virtually bulletproof 450HP engine. The I5 Configuration is the smoothest running, least vibration configuration design.
Not sure 2 turbos would be very balanced on a odd number of cylinders.

With a computer anything can be balanced. Now, would I trust them to get the programming correct. Absolutely not. They can’t even program a ****** radio with wifi properly. (I have already posted elsewhere about the 12” control panel programming issues.)

This reminds me of DSP in home theater audio. You can do a lot, trying to remove and/or add frequencies into the audio chain to try and fix nulls in your room or tame reflections. But in the end, a dead room is still better than a computer trying to fix the mess. That's what an inline 6 is, it's inherently balanced. Why futz around with an i5 when the better option is clearly the i6?

Just as a sample of what is happening out there with the I6 business, I went to a BMW dealer for a test drive of a X4 M and this was equipped with an I6 TT. In speaking with the business manager about warranties when I was pricing everything out as he was attempting to up-sell me to an 8 year plan, he said that a replacement engine is $40,000.00. At that point I declined the purchase.

I’m not sure what the cost of Stellantis engines will be but it is a warning sign, to me anyway.

BMW and Mercedes always have stupid repair and maintenance costs and depreciation reflects that. They are like a steak dinner. Enjoy it today, but understand tomorrow it'll have turned to ****.

Don't know why they (FCA/Stellantis) have not continued to perfect and refine the hemi V8 over the years. We still have to deal with broken exhaust manifold bolts.

Pretty much all German car brands are that way. Repair costs for my aging Audi are unbelievably high. With my extended warranty expiring in Sept, I'm starting to look at other brands to replace it by then.

Honda and Toyota are pretty reliable. But not a whole lot of excitement to be derived therefrom.

6=8 is a marketing slogan of Clifford Performance who specialize in 6 cylinder engines.
Also anyone who thinks you can’t get a nice sound from a 6 banger needs to listen to the 4.2 in my CJ.
I had a Clifford 6=8 decal on my 1978 Ford 300.

Inline is only superior for high torque @ low rpm. The rigidity of the load path combined with inherent reciprocating balance is an unsurpassed configuration for diesel.

V engines are for compactness and high rpm, so for high horsepower - not high torque.

Glad I didn't have the money to afford a Honda Magna back in the day. I might be dead.
Btw, Harley gets low torque from twin V by sheer displacement. My 107 cid is app. 1750cc.

I had the first year Sabre and for it's time it was a beast but then came along the V max lol...

Just watched a video of a mopar mechanic that just took a class on this new engine. It doesn't have a dip stick. He also stated the internals were a lot different from standard and the HO model. That you won't be able to just bolt on the HO stuff on the standard to up the hp.

But presumably there's a way to monitor oil level? My (16 year old) Porsche doesn't have a dip stick but it automatically displays the oil level on the dash every time you fill the gas. And you can manually check it any time you want.
Yes he mentioned it's got a sensor. I was not trying to knock the engine just thought it was interesting. Some fast change oil changers suck oil out using dip stick access so it's there problem not mine. Although I do have a oil extractor for my boat so could use this same method on a regular engine I suppose.
