Anyone have any info on what to expect? Will it be direct injected? What are the expected numbers for HP and torque? I'm guessing at least 320 hp. It wouldn't make sense to be too close to the 300hp turbo 4, especially if the 4 gets significantly better fuel economy.

Let us know if anyone gets any inside info on what to expect for this engine. I'm pretty certain it will be powering my JL through a 6 speed manual.

Jeep seems to have been tight lipped about the new 3.6-liter Pentastar V6 in the Wrangler aside from the rumor that it'll be paired with a new eight-speed transmission. They may not be able to squeeze much more out of it since the engine is already at 305hp/268ftlb in the 2016 Grand Cherokee.

Isn't the current 3.6-liter Pentastar V-6 in the outgoing Wrangler making around 285 horsepower? The 305hp from the Grand Cherokee would still be an upgrade in comparison.

Well, if currently at 305hp, then direct injecting it could easily take it close to 320. I think there are other ways to get it there, too. I wouldn't mind 305hp and maybe a bit more torque, or even the same torque peak hitting lower in the rpm band.

I'm not sure they are just tweaking it, either. There may be some significant redesign, too. The name has a good brand image, so even if it were significantly new, it would make sense to keep it at 3.6 liters and call it the Pentastar.

I'm really looking forward to seeing what they do with it. I'm hoping we get some info sooner rather than later.

Ok, so we now know the 3.6 will have Start/Stop, but I can't imagine they'd try and make that work on a manual transmission.

I'm still looking forward to hearing other details of changes to the engine, but most of all, the hp and torque numbers.

There is also info now about the option of a heavy duty alternator, larger battery, and auxillary switches. I think this package is available for all engines, though.

As far as I can imagine they will want to phase out the manual or at least make it so undesirable compared to the automatic that people will want to make the move. I have seen it before with other car makers and its kind of scary the impact it has.

Wrong. They wouldn't have developed it for the JL if that were true. Manual sales are still profitable on the Jeep. They found this out with the JK in 2007. Mine was ordered in January or early February of 2007 and arrived in late September as an 08. The reason? Higher than anticipated demand for manual transmissions. They've sold lots of them on the JK, and they clearly believe they will on the JL, as well. It appears the JL manual is a new unit, too. I'm not sure if it is a new design, but it will be new to the Wrangler. Spy shots of prototypes have shown a different pattern for reverse than on the current unit.

Actually you're right, that does sound about right and thinking back to those photos I doubt its just a new shifter but a setup they developed. Its more of a world product now than before so I can see that being another influence to offer manual.

That being the case the JL is an even stronger product to look forward to!

Well, we know the six-speed stick is going to be offered, but not which engine it'll be offered with. Could be a diesel only offering?

The way I interpret the latest info, it will only be offered with the 3.6, and not the diesel or 4cyl.

Just looking at current hp/torque figures, I would think we could at least expect 300hp and 300lb of torque in the new 3.6. That would be a modest, but nice increase, especially if combined with a 200 or 300 pound weight reduction in the JLU.

I have to admit, the Ecoodiesel, with 240 hp and a whopping 420lbs of torque at 2000rpm is making me rethink. I just don't think I could stomach the 5,000 dollar premium I believe it would command over a 3.6/manual. I'd have withdrawls from rowing gears, too.

If it is available right from the start, it might give me pause. Especially if the 3.6 doesn't make the 300hp 300 torque mark.

Update...I just saw that the current 3.6 makes only 260 lb of torque, so maybe 285 would be a more reasonable gain. I still think 300hp should be the minimum, and if they go with direct injection, we should see 315 or more. Chevy's reworked 3.6 puts out 308hp and 275lb ft of torque. They should at least match that.

Btw, the old 3.8 in my 2008 Rubicon is almost as good as the Pentastar with torque. They really need to bump that up. I'd sacrifice the hp gain to get that torque number to push 300.

I actually won't be surprised if a lot of people don't bother upgrading to the JL and instead just keep their JK's. With a product so good its going to take a lot to see a major shift in owners.

A lot will definitely keep their old JK, especially if they've put in a lot of money and time into modifications. But a 3.6-litre V6 engine is very appealing, especially if it really does have north of 320 hp and equally impressive torque numbers.

It appears the 3.6 will be at about 305hp and the same torque as before, but it will, according to FCA, have 14% more torque from 1,000 to 3,000 rpms. That's a modest increase, but it should be easy to feel, especially if there is any weight reduction in the JK.

Right now, I'm leaning toward the diesel, but I won't wait too long for it. If it doesn't show until 2019, then I'll be in for the 3.6 manual.

Was hoping for something closer to 320 as that was in your initial thread post. Why do you think it'll be around 305 hp instead?

At least we're a long enough way out till diesels get banned, car makers and even people like us are probably living in one of the last decades of mass diesel passenger vehicles being offered .

its a bit scary when you look at where most EV's are being sold meanwhile diesels are also being pushed a lot here

Here's a look at the goals by country:
Britain: The U.K. said Wednesday that it would ban sales of new gasoline and diesel cars starting in 2040 as part of a bid to clean up the country's air.
By 2050, all cars on the road will need to have zero emissions.
"We can't carry on with diesel and petrol cars," U.K. environment secretary Michael Gove told the BBC. "There is no alternative to embracing new technology."

Nearly 2.7 million new cars were registered in the U.K. in 2016, making it the sixth biggest market for car sales in the world.
Stephanie Brinley, senior autos analyst at IHS Markit, said getting rid of gas-guzzling cars would be difficult. But if politicians are serious, manufacturers will have to respond.
"The big automakers are highly unlikely to just abandon the market," she said. "They'll find a way."
France: The government announced earlier this month that it wants to end sales of gas and diesel-powered vehicles by 2040 as it fights global warming.
After that date, automakers will only be allowed to sell cars that run on electricity or other cleaner power. Hybrid cars will also be permitted.
Nicolas Hulot, the government official in charge of France's "ecological transition," said the goal would help the nation's automakers "innovate and become market leaders."
The share of cars powered by electric, hybrid and alternative fuels in France is small -- about 4% -- but growing fast. Sales of those vehicles were up 25% in the first quarter of 2017.
India: New Delhi said earlier this year that every vehicle sold in the country should be powered by electricity by 2030.
"This is an aspirational target," said Anil Kumar Jain, a government energy adviser. "Ultimately the logic of markets will prevail."
India, which suffers from an especially acute air quality problem, is home to many of the world's most polluted cities.

But it's also a country where policy can make a big difference.
The number of cars on the country's roads is expected to explode over the coming years as four-wheel vehicles become more affordable for the middle class.
If families purchasing a car for the first time are able to buy electric, the country could leapfrog ahead of some developed economies.
Norway: The government's transportation plan outlines a clear target: All new passenger cars and vans sold in 2025 should be zero-emission vehicles.
The country is considered a leader in this area. About 40% of all cars sold in the country last year were electric or hybrid vehicles.

The others: At least 10 other countries have electric car sales targets in place, according to the International Energy Agency.
Austria, China, Denmark, Germany, Ireland, Japan, the Netherlands, Portugal, Korea and Spain have set official targets for electric car sales. The United States doesn't have a federal policy, but at least eight states have set out goals.
China -- which buys more cars than any other country -- is also the largest electric car market. China accounts for more than 40% of the electric cars sold in the world and more than double the number sold in the U.S., according to the IEA.
The IEA report contains an alarming statistic that shows just how far many other countries have to go:
Globally, 95% of electric cars are sold in only 10 countries: China, the U.S., Japan, Canada, Norway, the U.K., France, Germany, the Netherlands and Sweden.

Because FCA says they are using the updated 3.6 already for 2017 in the Ram and one SUV, (Grand Cherkee?), and it is 305hp and has the same torque peak, but they claim a 14% improvement in torque between 1,000 and 3,000rpm.

That's a solid increase, but yeah, I'd have loved to have seen 320hp and/or 300lbs of torque.

I'm sure engine tuning is taken into account during the development stages, they're never preforming at optimal levels for maximum output, that's why tuning exists because there's potential.

it could even be a case of them not factoring that in because whether they do or don't, aftermarket will still come along and make the changes they have set out, as long as there are buyers, they will make it. there might be road blocks from time to time but tuning culture never dies.
