6.4 Hemi
5.7 Hemi
3.2 Pent.
3.6 Pent.
3.0Turbo Diesel

Now

Turbos and direct injection.

Geeesh!


Well , I remember my dad smiling when I brought my 1st girlfriend around, he was so proud.
I loved making him proud.
So I started bring all these different girls around.
He suddenly stopped smiling and asked me ,"What are you doing!?". I said "what?".

He said...

"Sometimes when you have too many , you really have none.
GO FIND A GOOD ONE!"

Re: 2016 to get twin turbos?

Haven't the 2 hemis been reliable? Why mess with a good thing...there's a solid market for the v8's. It's a huge selling point for me.

And I think you forgot the gold old 4.7 V8 that went away a few years back....She was a good girl.

The hemi is a solid engine that is reliable and for the performance you get is reasonably efficient. You can further increase performance and efficiency with DI and such. But turbos are a way to game the MPG numbers so that's what everyone will go to.

This will be our future way things are going, and if the Liberals like Obama have their way:





Folks might want to hold onto their current V8s.

Re: 2016 to get twin turbos?

If the power output was reasonable, I'd be fine with a twin turbo six. I've got a tuned BMW 535 putting out about 390 hp from three-liter turbocharged six. Tune only, no other mods. For me, this is one of the really appealing points in favor of a turbocharged engine...once the code is cracked, it's easy to bump up the power and torque without compromising reliability (assuming one is not a dumbass).

Re: 2016 to get twin turbos?

I might even go for a basic DI upgrade for the NA PentaStar in the JGC- as long as rear limited-slip or locker (like KL TrailHawk) is available, unlike now. Wouldn't mind having start/stop either.

Re: 2016 to get twin turbos?

Bottom line for me-

If a v6 jeep is the only option then I'm out.

If the SRT lives on then I'll go that route.

Re: 2016 to get twin turbos?

I see a lot of emotion and little facts.
- The Ford ecoboost is a sucess. People love them for towing.
- In the last century, the diesel was king for cost per ton-mile. The government fixed that.
- Gas engines are less expensive to build than diesels mainly for the add-ons (e.g. DEF) - even adding direct injection.
- The torque band on DOHC engines with VVT is essentially 1500 rpm to redline. The redline of a small (3.0 liter) gas engine is usually 1,000 rpm higher than an equivalent diesel.
- 87 PON is less expensive then Diesel

So what you have with a direct injection 87 PON turbo engine is a cheaper engine to build that can get equivalent mpg on cheaper fuel, and has a greater torque area (area under the torque curve - see "tractive effort") than an equivalent diesel.

Can still sell diesels overseas where the tax structure and relative fuel costs still favor them. But in the US "the rules are different here".

ps I've had a turbo diesel and really liked what it could do but can do more today with a gas engine. Just my opinion.

pps don't care about the number of cylinders, just find it easier to tune a six. Importnt thing is a 3.25" stroke and about a 500cc cylinder. Math on why is a little complex.

Re: 2016 to get twin turbos?

CAFE needs to be canceled. Hopefully that will happen in 2017. With fuel prices greatly decreased, I suspect many vehicle makers realize they have made bad decisions. I do not like the sound of V6 engines, and many of us want a V8 with rear wheel drive (or rear-based four wheel drive). That is a major reason sales of four door pickup trucks are so high. I very much liked my 2006 Ford Explorer V8, and since Ford turned the Explorer into a front wheel drive junk, I replaced it with my 2014 Grand Cherokee V8.

It's the number of 4 and 6 cylinder engines being sold that help auto makers meet those corporate CAFE standards so they're still able to sell V8's.

I doubt very much that CAFE standards will ever be cancelled. Fuel prices are and always will be a volatile commodity. There's a finite supply of it. We just happen to be enjoying an unprecedented drop in oil prices at this time. I'm enjoying it while it lasts but it will eventually go back up.
