2016 to get twin turbos?

From what I was reading today the 3.6 is supposed to get twin turbos and direct injection for the 2016 model year. The Grand Cherokee is supposed to be the first vehicle to get this engine. I wonder if it will replace the 5.7?

I think that is the theory, to move away from v8s and use more economical turbo 6 cyl engines (as per Ford ecoboost). There was talk of them using the pentastar with turbos in some maseratis.

I hope they keep the Hemi as an option. I ignored the new explorers because they only had the 6, same with the new 4runners.

If this does happen I guess I'll have to switch to BMW or an SRT. Go ahead jeep, give me an excuse....
Same here. If a V8 was not an option I just moved on to the models that did offer them. I passed over the 4-runner, explorer, pathfinder, ect. The anti V8 agenda is the result of the crazy Government gas mileage requirements. This has also caused some great models from even being offered in the US. Maybe people will actually think next time before they pick a leader.

If Chrysler makes the switch to twin turbos, they will have a lot of problems initially, just as BMW and Ford have with their initial efforts at gas turbo charged engines. They save fuel if you have a light foot on the accelerator, so that the turbos don't spool up that much. But if you stay on the boost, your mileage will be as bad as a V-8 if not worse.

I'd pay more as long as I can get what I want. Id be mad at myself if I settled for a v6 to save 10 grand.

I have a feeling the v6 turbos will cost more also. So, if a v6 turbo overland runs me 55ish, I'll gladly pay 10-15k more to have a true beast instead of a wanna be beast.

My guess is there are a lot of people who feel like I do with regard to engine size, at least I hope that's the case....

I'd love a petrol/gas v6 turbo. Nissan have been doing them for years with the skyline (my first car was a GM Holden Commodore with a nissan turbo 3l straight 6), as long as you look after the oil they can be very reliable. And torque delivery is great, along with lots of tuning options.

Given there is time for development and refining these new power plant versions, the end result could be surprising. ('could be a dud, too, but I suspect that's less likely)

If a turbo v6 will move the GC better than the 5.7 Id consider it. I'm sure it's possible.....but then again...aligning the trim properly is also "possible".....

See what I'm getting at?

I doubt Chrysler gets the twin turbo right the first time around....my prediction-the next body style will be absolutely GORGEOUS, and the engine, if it's a v6 twin turbo, will underwhelm.

Just my personal nightmare, er, opinion.

Yea I can't really imagine those engines will hit the market with no issues. I don't think Chrysler puts anything on the market without a bunch of issues that need to be worked out...at least from what I have seen. I think I would give it a good 18 months to 2 years before I would want to buy one.

The only way I'd be happy with a Turbo V6 would be if it had V8 range performance. And by that, I mean:
- 0-60 in under 7 seconds or better
- 350 HP + with similar torque

The only SUV that even comes close to offering these kind of numbers is the 2014 Range Rover Sport which has a supercharged V6:

It has a 3.0-liter 340-horsepower supercharged V6 engine with start/stop technology, creating 332 lb-ft of torque

Remember...

There is No Replacement for Displacement!

Every now and then it would not hurt to Google (or Bing) a bit about turbo engines. Now, I am most definitely NOT the authority on turbocharging but I have been through turbo, intercooler, up-pipe and down-pipe replacements in my life. And 3-4 retunes on the dyno and 7-8 street tunes. Turbo lag is a non-issue in modern cars with 2-3 turbos. It is not an issue in my single scroll TD04-16G. It categorically is not an issue on a twin-turbo charged engine.

The replacement for displacement is called turbo. It is valid in F1. It is valid on the street. In the 1980s, in qualifying, cars would have more than 1300 horsepower from a 1.5 L V6 engine. At the height of the V10-V12 era (pre-Senna accident in 1994), from an engine more than twice as big (3.5L V12) they were barely scraping 800 hp.

The only thing better than large displacement is a large displacement engine with even more cylinders and turbos (AUDI RS7 :drool:). One could make the argument that it is not so much the displacement (engine size) as the sheer number of extra cylinders that makes the difference. I am quite certain that not many of you would find a 5.7 L V6 exhilarating to drive. Nor do I think people would prefer a 4.2 L inline four to the AUDI's 4.2 L V8. And last time I checked the new M5 (V8, turbo) was faster than the V10 larger engined predecessor.

I would trade an SRT and all its 6.4 L mighty Hemi V8 for a 3.0 supercharged Range Rover (340 hp, 332 lb-ft) on engine alone. A turbocharged 3L V6 should be even better. A simple look at BMW tuner DINAN
Products - Dinan, Leader in BMW Performance Parts and Upgrades
shows what is possible with a simple ECU reflash for a 3L V6 turbo engine: Stage 1 adds 44 HP and 58 lb-ft. Add a few other toys: 98 More Horsepower / 129 More lb-ft of Torque (Stage 3) which puts it on par with the V8 M3.

And yes, I have driven tuned BMW cars. Most recently was last summer behind the wheel of a buddy's 135i. I hate BMWs but the engine and the chassis were superb. In fact the owner is on this Jeep board. And in fact a common friend has a V8 M3. And in fact I July when I last drove the 135i, the 135 pulled out of corners faster than the M3 at our undisclosed cornfields test grounds :rolleyes:

And i guess then there's this
http://truckyeah.jalopnik.com/2016-mercedes-benz-gle-450-amg-coupe-this-is-it-1669052554
The biturbo three liter V6's output has been posted at a fairly hair-raising 362 horsepower and 384 lb-ft of torque on tap from just 1,400 RPM.
A new identity crisis from Mercedes.

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!"

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).

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.

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.

Don't say that, not just yet.

Me too! I love the growwwwwwl of my Hemi when I stomp on it! Turbo . . . bleh!

Twin Turbo will be awesome. Here in Australia they have a Ford Falcon Ute with a 4.0 Straight Six with single Turbo. Properly modified and tuned, the thing can be a monster. Speaking of monsters, the Nissan Skyline GTR is a 3.8L Twin Turbo. I know it will be a Jeep and a SUV but I wouldn't discount it just yet.
