    No, The Wrangler's Turbo-Four Will Not Produce 368 Horsepower

      368 Horsepower? Yeah, about that...

    The internet went aflame last week when a NHTSA filing revealed an interesting tidbit about the next-generation Jeep Wrangler. The turbocharged 2.0L four-cylinder was said to produced 368 horsepower. A crazy number and one that made a number of people - some here on our forum question whether that was actually true or a mistake.

    It seems to be the latter as The Truth About Cars found an updated filing from FCA which now lists the turbo 2.0L at NR (Not Rated). Everything else on the table is unchanged.

    A source at FCA told Road & Track last week that the 368 figure was 'dead wrong'.

    For now, we'll to have wait patiently for Jeep to debut the Wrangler or for another leak to come out.

    Agreed.  Although if it makes 268 hp and 280 lb-ft, what is the point of the Pentastar that is like 290 hp, 260 lb-ft?  Now you have 2 powertrains with the same power output.

    One had much less lag. If your rock crawling, you don't want to be into the turbo all the time just to get your torque.

    Any car maker that isn't 100% turbo by 2020 is way behind the times.  The Pentastar V6 should be turbo only.  

    The one place the turbo 4 makes most sense is over seas where the Pentastar will get hit with displacement tax.

    If your v6 larks torque, you built your engine wrong.  If your 4cyl lacks torque, you built a Honda engine.  A Jeep turbo 4 is silly when they can use the Pentastar v6 and add some more torque.  How do you haul and tow and climb rocks with a turbocharged 4cyl?

    Ya Don't! :P 

    Always said these high HP low torque engines with dual overhead cam crap are just marketing fluff for idiots that cannot understand real torque is the answer, not butt loads of HP.

    Will take a properly built pushrod V6 or V8 over turbo everything in today's driving of needing torque to move along.

    I am guessing 268 HP and higher torque and tuned for the torque to hit early and hard.  Jeep understands their audience.  The Pentastar was redone in 16 in the GC and Durango and provides a much better torque curve and is much torquier lower in the rev range.  Of course the ecodiesel will be the torque monster, but am sure the other engines will work just fine off road.

    You really need to stop looking a peak output that only happens under full throttle situations.  The coming Benz electric turbo might change things, but for now, the only time you'll be getting that huge torque is when the turbo is fully cooking. Absolutely the wrong situation for driving a Wrangler.

    I have no problem with a turbo 4 in a Wrangler as a base option for suburban warriors who only buy it for looks. It is not a V6 replacement.

    Expand  

    The turbo 4 replaced the V6 in almost every sedan, from Sonata to Malibu to CTS to E-class.  And the turbo V6 replaced the V8 in the F150, replaced it on the Audi RS4, E43, etc.  

    The Wrangler has 285 hp and gets 17/21 mpg, a Turbo 4 can get near that power and beat that MPG.  A turbo V6 can be the upgrade.  GM has the same problem with their 3.6 V6 in a lot of vehicles, mainly Cadillacs.  It doesn't offer much difference in acceleration or fuel economy of the 2.0T and it is way outgunned by German V6s.

    For fun:

    2005 Chrysler 300C  340 hp, 390 lb-ft  17/25mpg  (5-speed)

    2017 Chrysler 300C Hemi 363 hp, 396 lb-ft  16/25 mpg (8-speed)

    That is what 12 yeas of advancement got? 

    By comparison, progress being made in Stuttgart:

    2005 Mercedes S500 4Matic  302 hp, 339 lb-ft,   16/22 mpg  (5.0 liter V8)

    2018 Mercedes S450 4Matic  362 hp, 369 lb-ft,  18/28 mpg  (3.0 liter V6)

    2018 Mercedes S560 4Matic  463 hp, 516 lb-ft,  17/27 mpg  (4.0 liter V8)

    1. Having to use a lot of turbo in the type of slow speed rock crawling the Wrangler does is a BAD IDEA.

    2. The Chrysler and GM V6es are not being out gunned by the Euros. You don't get a euro turbo V6 until you pay GM turbo V6 prices. GM is out gunning the blown 4 pots the Germans will sell you using V6es. If your only choice in a car is a turbo 4 or a naturally aspirated v6, you'll get the V6. 

    The EPA numbers for the LX cars are always under rated.

    With displacement increases.  Chrysler should have a 3 liter V6 making more power than the 2005 5.7 liter Hemi V8.  Alfa does, so it is doable.  The Pentastar should be turbo to 370 hp as the upgrade from the myster horsepower turbo 4.

    CAFE also goes up like 10% per year in the 2020-2025 time frame.  They are paying fines now, they need massive gains.  And all this stuff should be electrified in some way post 2020.

    AMG has 603 hp, 627 lb-ft from a 4.0 liter V8, 485 hp out of a 6.4 liter is a joke, even the 2007 Mercedes 6.3 had 510 hp.  And they replaced that engine twice already.

    Chrysler raised displacement 0.5 liters and horsepower over DOUBLED.

    how much of a joke is 510 HP out of 6.3L against 707HP out of 6.2L?

    And I didn't even mention 840 HP out of 6.2L.

    They still sell the 5.7 liter as the option in the 300C, which is why I compared an S500 then to an S560 today, same model.  The Mercedes 6.3 is 10 years old and has been out of production for years, no point to compare it to a engine introduced in 2017.  Mercedes can win any HP/liter argument too because they have a 700 hp 1.6 liter V6, but never mind that, not the point.

    The Demon and Hellcat make a ton of power, no doubt.  Terrible fuel economy but nonetheless huge power.  Problem is Chrysler's mainstream engines are bad.  And they haven't seen increases in fuel economy and power as others have.

    But the 5.7 is no longer the only Hemi- there are 3 distinct displacements in the family but they are all 'Hemi's.
    Without question Chrysler has (massively) upgraded Hemi power as opposed to your claim. The tiny adjustments in displacement are irrelevant. The fact that there is still a 5.7 with similar power levels is also irrelevant, beside the fact that  375/410 power numbers are more than enough for most drivers as it is. Name another brand that has increased power in the same engine family to this degree in the same time period.

    But no gas mileage increase, and CAFE in 2005 was around 27 mpg, in 2025 it is 54 mpg.  In 12 years they went no where, now they have to double the fuel economy in 8 years.  

    375 is definitely a lot of horsepower, but a six cylinder can make that.  The Pentastar should replace the 5.7 Hemi with equal power but a 5 mpg advantage.

    The V6, the vast bulk of the sales, just got it's upgrade last year for a few of the models that got refreshes. They haven't even added Direct injection yet, though the Pentastar is designed for it, and it is still competitive.

    Expand  

    But they went from 350 hp to 363 hp in the Chrysler 300.  

    An 06 S500 4matic got 14/20 mpg out of its 302 hp V8,  the 2018 S560 4Matic gets 17/27 mpg with 463 hp.  Adding 160 hp and 7 mpg highway is pretty good.

    The S63 went from ab6.3 V8 with 518 hp, 11/17 mpg in 2008, to 5.5 liter V8 with 577 hp 15/23 mpg in 2013, to 4.0 liter V8 603 hp 17/26 mpg in 2018.   9 mpg highway improvement with adding 85 hp and 160 lb-ft of torque.

    So the point is you can raise power and fuel economy at the same time with engine downsizing, turbos, DI, etc.  Use the technology, Chrysler doesn't do that.

      I believe that you can get a good read on people - most of the time - and I knew I never liked him early on, not knowing much about him.  Then, when you read about him in more detail, it's both off putting and corroborates what you guessed in the first place. After driving that rented Tesla, and which I promptly exchanged, I know I would never want one of their products.  In the last year, I walked up to a parked Chevy EV (Bolt, not sure) and, while an EV, everything, such as the dash, looked more conventional and with a reasonable learning curve. I have way more questions than answers when it comes to EVs.  The next one for me is going to be ICE or hybrid.  The range on that rented Tesla was also not enough for the long distances and open spaces I'd be covering.

      Genesis is on my list, specifically the GV60. The EV GV 70 also seems to lease well. We went to the Pittsburgh Auto Show last month (ewww, public days, I had to mingle with peasants) but oddly, the Korean trio brought very few EVs. Only the EV9 was there. He did like the look of that one, but the ZDX is more his size. I wanted him to look at the EV6 and the Ioniq 6, but neither were there.

      Narcissist never think they are wrong, nor do they ever think what they do should affect them. I also think he is looking to mess up the government more so that his companies can take over key areas to run increasing his perceived power, control and money. To Musk, he probably thinks the drop is a short-term thing as anyone that goes against Tesla is now considered a Terrorist. The conversion from Democracy to Fascist communism with what he sees as everyone should only be driving a Tesla is his narcissistic view imho. This is why I hope Tesla now fails as an auto company and everyone else succeeds as he clearly is out of his Ketamine fueled brain.

      Genesis News: Genesis debuts a Long Wheelbase G90 Black Edition

      By G. David Felt · Posted

      The G90 Black edition in long wheelbase did not come about by the normal approach of someone saying they wanted a black auto, as an all-black trim is nothing new in today's evolving auto industry. To understand the passion that went into this top-of-the-line executive trim G90 Long Wheelbase edition, you have to first look at the team that has brought about the ultimate Black Edition. Genesis turned to an all-woman trio in asking them to build the ultimate luxury Black Edition in the auto industry that would successfully set itself apart in the auto industry.   BLACK is the origin for everything in reflecting on what the color would mean for the brand. The ladies felt that both Genesis and black symbolize creation, and particularly a focus on essence. By blacking out all exterior and interior elements, we are showcasing the pinnacle of our brand identity, “Athletic Elegance.” The next step was to review how the competition approached black and how Genesis would approach it. The trio of ladies noticed that everyone had a flexibility in offering shades of black both externally and internally allowing one to find differences on each auto.  In contrast, every element of a Genesis Black model, big or small, is uniformly black. Just pure black. This creates a harmonious blend that underscores black’s elegance.  The final attention to detail was not just the Crest Grille, wheels, emblem, wood garnishes and doorsteps, but even the tiny buttons and switches were all developed as Genesis Black-exclusive details that required changes in their manufacturing methods. Even the Bang & Olufson logos on the speakers were made in a darker shade.  Working with wood, leather, various metals, required endless rounds of sampling to create the ultimate natural mix of black, ensuring every inch would have a luxury feel while matching the surrounding elements. This is shown in the attention to detail that shows from the dash to the seats, including the back seats. The Black Edition team had to considering how each vehicle contains tens of thousands of parts, changing just one — even its color — prompts a chain of questions they had to investigate and think through, like how they will affect operations on the factory line.  Sustainability was an important part of how they would use materials and as such recycled materials to better ways to tan leathers or stain natural woods were researched. As such the Black Edition had driven sales as even more favored among customers as shown by sales figures. The goal was to have customers take pride in owning a Genesis Black Edition from the G or GV 80 or 90 series. The complete blackout of the G90 Long Wheelbase has been enhanced by ensuring every little detail is a perfect matching black. From the moldings around various points on the exterior such as the bumper moldings to headlamp inner side bezels. The Genesis Black Edition has taken it to the littles details throughout the interior ensuring that everything matches even the audio-visual systems when they are off. The Navigation system even has a special black mode. Some might feel it to be a bit extreme, but even the Smart fob for running the auto as well as the engine bay are ensured to be a matching black. The welcome and goodbye animations, 2D and 3D vehicle images and graphic themes used are all special Black Edition to match the auto.   The G90 Long Wheelbase edition will be available only with a 3.5L turbo gas motor paired to a 48-volt electric supercharger system and all-wheel drive. Specifications will vary depending on region and Genesis has stated that interested parties should contact their local Genesis luxury retailer for more information.     View full article
