Jeep News: Rumorpile: Details On the Hurricane 2.0L Turbo for Wrangler

14 posts in this topic

Last month, Fiat Chrysler Automobiles announced a $75 million investment into their Trenton Engine Complex to build a new four-cylinder engine. Automotive News has learned some details about this new engine and where it could end up.

 

According to a source, the new four-cylinder is codenamed Hurricane and it will be a turbocharged 2.0L. The engine will feature direct-injection and a twin-scroll turbocharger. Hurricane is expected to produce almost 300 horsepower.

 

This seems like a perfect engine to drop into a hot version of a compact model, but Automotive News says this engine will likely appear in the next-generation Wrangler. FCA CEO Sergio Marchionne has hinted the Wrangler would have the option of a four-cylinder paired with a new eight-speed automatic. This would likely improve the current Wrangler's fuel economy of 17 City/21 Highway with the current 3.6L V6 and five-speed automatic.

This would be a good start for the updated Wrangler, but then they should also have a Turbo V6 to have a performance model like all the other products.

So will the new base engine be a downsized 3.2L Pentastar to give more separation to the 300 hp 2.0T? I can't imagine people wanting to upgrade from a stout, smooth 300 horsepower V6 to a 300 horsepower 4-cylinder, regardless of torque or FE advantage.

All that is anyone is certain is that the Wrangler will have a revised Pentastar V6. I don't know if it's going to be the 3.2 or 3.6L.

Won't the Wrangler also have a new transmission?

 

Anyways, I guess refinement of the engine need not be an issue given the intended purpose of the vehicle.

Yes, a new eight-speed automatic. It is badly needed. I drove the Wrangler seen in the picture and got 16.7 MPG for the week. I wonder how much the eight-speed would have improved it.

The other side of the coin is this: we've seen 4-cylinder turbos come out of Fiat with underwhelming results before. Their 1.4T was rated 160 hp/184 tq and many of the cars using it can barely get out of their own way. I recall a Dart 1.4T with an automatic transmission testing slower than a Cruze automatic with 138 horsepower/148 lb-ft, and the cars were close enough in weight not to make a difference.

 

Is this "hurricane" 4-cylinder going to make real power or spec sheet power?

I said a while ago that they need a 4-cylinder Wrangler.  This was more horsepower than I was expecting.  I think they need a base 4 cylinder with like 200 hp (for 2 door models), but the Wrangler also needs to lose some weight and size.   In the 70s, 80s, 90s, there was always an entry level Wrangler, now it is like a $30k base model with a 280 hp V6.  They priced a lot of former fans out of the market I think.

Normally I'd be like... boosted four cylinder in a Wrangler....NEVARRRR!!!

 

But if some guy from Ferrari, becuz Sergio put the head of Ferrari powertrains to be head of Alfa powertrains....jeezus, Ferrari engines in a Jeep? A Wrangler of them all? Why not?!!!

Base Wralgler starts at 24k and I too thought the 4 would have been more a 200hp/tq type of engine and then 300ish for the v6.

Also, the next gen wrangler is supposed to be aluminum so it will be losing weight as well because i also agree that it needed a diet or something to be able to comply with the ole CAFE. And aluminum and whatever high gear ratio tranny should help a fair amount.

I am pretty sure MacGyver's Jeep wasn't nearly as big as todays or needed that much power.  I just looked up a late 80s Wrangler, they were 153 inches long and 2,850 to 3,241 lbs.  Base 4 cylinder and the straight six optional.  Today's Wrangler is 3,700-4,400 lbs.  It gained like 1,000 lbs, meaning you have to put a V6 in, up the cost.  But it is more popular than ever so maybe people want bigger.

Wrangler or not, this Turbo-4 is badly needed by FCA across the lineup.  With those kind of power numbers, I bet we'll see it in a host of products including the Charger, and Cherokee, and possibly even the Pacifica.

      Fiat Chrysler Automobile has quietly ended production of right-hand drive models from Chrysler and Dodge. According to South Africa's Wheels24, the announcement comes as FCA drops Chrysler and Dodge from their South Africa lineup.
      "FCA will say a fond farewell to two of the mainstay car brands, with the Chrysler and Dodge vehicle ranges no longer being available locally. This unfortunate situation has arisen from our principals in the USA no longer building Chrysler or Dodge vehicles in Right Hand Drive configuration," the company told Wheels24.
      According to Allpar, FCA built RHD variants of 300 and Charger in Brampton, Ontario, and Pacifica and Grand Caravan in Windsor, Ontario. It is unclear if this move will affect other markets where FCA sells RHD models such as Australia, New Zealand, and Indonesia. When reached for comment by Australia's CarAdvice, FCA Australia's manager of public relations Alessia Terranova said,
      “I am not at liberty to comment on South Africa’s decision. What I can tell you is that Australia will continue to sell the right-hand drive Chrysler 300 as an ongoing product in our lineup. In relation to Dodge, at this stage, this brand is represented as a parts and service operation only.”
      We'll keep you posted on this story.

      If you need a distraction on this Monday, may we point you in the direction of the 2018 Jeep Wrangler Owner's Manual and User's Guide. JL Wrangler Forums discovered both books on a public FCA Canada website and has provided PDFs of both for your perusal. 
      Is there any new information that can be gleaned? Yes.
      There will be a power-retractable hardtop. However, the top is not removable. A 4WD Auto mode that will shift power between the front and rear axles when needed. UConnect system featuring pages for off-road settings Max towing capacity of 2,000 pounds for 2-door models, 3,500 pounds for 4-door models.  The manual mentions both the turbocharged 2.0L four-cylinder and 3.6L V6, but doesn't mention power output. Thanks to an earlier leak, we know the 3.6 will produce 285 horsepower.

      If there is one thing the Fiat Chrysler CEO Sergio Marchionne has been consistent on aside from changing his mind on a number of things is his dislike on electric vehicles.
      Speaking to reporters this week at the New York Stock Exchange, Marchionne said there isn't a viable economic model for electric cars.
      "We still don't have a viable economic model for delivering an electric car. As much as I like Elon Musk, and he's a good friend and actually he's done a phenomenal job of marketing Telsa, I remain unconvinced of a ... economic viability of the model that he's pitching," said Marchionne.
      Marchionne believes the costs for batteries and the various technologies need to come down to make them viable. Otherwise, automakers should focus on developing hybrid and plug-in hybrid powertrains. 
      "So how do we find a convergence of technology bringing prices of components down and allows us to price accordingly — or we need to navigate through this process in a combined way between combustion and electrification to yield at least a minimum of economic returns that allows for our continuity? The last thing you want is me to be successful selling cars for 24 months and then go bust. That's not a good story. Especially in a place like this which rewards economic success. Let's not sit here and design our own future in the tank. Let's try and do it properly. We will do all the right things. We are investing without making a lot of noise on electrification. We will combine it with combustion to yield the right level of CO2. But we're not betting the bank on going fully electric in the next decade. It won't happen," said Marchionne.
