It looks like the 5.7L Hemi days are numbered and will be replaced by a turbo 3.6L.

Those will be hotties.:driving:

I hope Mopar has studied the lessons of carbon buildup in GDI mills and engineered accordingly.

Why are some direct injection engines more prone to deposits?
If you look up direct injection carbon deposit problems on the Internet, engines from BMW, Audi and VW always rank the highest. Engines from GM and Ford that have been on the road for at least four years hardly have a carbon deposit complaint. What’s the deal?
Some direct injection engines have bad timing. The modern engine typically has variable valve timing and even cylinder deactivation. The engine management system can control when, how long and, in some cases, how deep the valve goes into the combustion chamber. If an intake valve is dropping into a combustion chamber with combustion byproducts or unburned fuel, the valve might be exposed to the precursors that cause carbon build-up.
Some have blamed the positive crankcase ventilation (PCV) systems for leaving an oily film on the intake valve that is then baked into carbon. Some blame the valve overlap during the intake stroke that eliminates the need for an EGR valve.

While I see the turbo 3.6L gaining more market share as stated in the article, I don't see how that means the "5.7L Hemi days are numbered and will be replaced by a turbo 3.6L".

Expanding that information into speculation of the V8 dying is just that...speculation. While they may have less market share, they will likely still be around for quite a while.

Imagine what applying turbo technology to the 5.7L would mean for fuel economy and performance.

Fiat/Chrysler hasn't upgraded the 5.7L for 6 years and with cafe standards being raised I can't see it being kept in the line-up for much longer. 5.7L hasn't improved much in fuel economy even with the new 8 speed, 16 mpg city is pretty bad for 2015 models.

My guess is the 6.4L will be kept for the low volume SRT and they will follow Ford with 3.6L turbos used instead.
Can't see the 5.7L being turbo charged as they have the 6.2L for that.

Would be nice if they made a 'bolt on' it for the current gen v6's...

 

[iamstubb]

That will make and already good engine much better. Can't wait!

I have known this for a while. 3.6L got a black eye on the head issue with the wrong reamer size.

Direct injection is going to have power increases and operating challenges especially with the volatility of the fuels and the oils. Tighter tolerances and vapor recovery are part of it not percolating vapor back into the intake.

Been working for a while on GDI engines and also GDI QuantumBlue Engine Oils for when this takes place!:bigthumb:

The 3.6L DI twin turbo will be considerably more expensive than the 5.7 Hemi!

They didn't upgrade the previous version for about that long either (03-08). It may go away in the cars (I doubt it, even if only for the police market) but I can't ever see it leaving the trucks.

Hmmm... I knew they turbocharged the 3.6 for use in the Maseratis as well. Which is cool because we can now say that we basically have a Maserati motor in our Dodges

Misnomer. It's doubtful that they'll drop the mid range Hemi option. They wouldn't kill a motor that makes big sales and is an integral part of the name brand. It's like BMW saying they're switching to V6 from straight sixes.
I have a feeling that the 5.7 will co-exist alongside the 3.6 as a less expensive variant. Sort of like the 3.7 and 2.0T do in the Ford Mustang
