    Rumorpile: FCA To Switch from V6 to Straight-Six Engine

      Hasn't been a straight-six engine in a FCA production since the 2007 Wrangler

    Fiat Chrysler Automobiles is considering replacing the Pentastar V6 with a brand new straight-six engine. A source tells Allpar the new engine will be based on their new four-cylinder Global Medium Engine (GME) - what is found under the hood of the Jeep Wrangler and Alfa Romeo Giulia. This will allow FCA to build the engine alongside the four-cylinder variant.

    Not many technical details are known about the engine aside from it being pegged around 2.9L to avoid taxes in certain European countries. We might expect larger displacements for trucks and SUVs. Production could take place at FCA's Dundee and Trenton, Michigan plants. It is expected that Ferrari will use a variant of this engine for Maserati vehicles. No timeframe as to when this new engine could debut.

    Allpar also mentions in their report that FCA was considering adding some sort of boost to the Pentastar, but ran into issues with the size and power constraints.

    running into issues with size and power constraints tells me that the V6 was already built at it's maximum potential. Sad failure to build an engine that way.

    Seems the story at Auto Evolution states the following: Love it or hate it, the Pentastar V6 is getting on a bit. In addition to age, the six-cylinder suffers from cylinder head failure and overheating of the valve seats. The cam phasers, oil filters, and cap O-rings also leave much to be desired from a naturally aspirated engine.

    Sounds like FCA heard Mercedes was doing this, and said “well they know what they are doing, let’s do the same thing”

    It does make total sense though, you don’t need more than 275 hp in a front wheel drive car, the chassis can’t really handle it, and you can get to 275 hp with a turbo 4 or hybrid, etc.  Over 300 hp is going to be a rear drive vehicle and the inline six makes the most sense for that.

    Sounds like FCA heard Mercedes which heard BMW. Jabroni.

    It does make sense for all manufacturers to do this as I4's are super common so building an engine family off the most commonly produced engine makes sense.

    Tell Honda that a FWD chassis can't handle more than 275hp.

    BMW never stopped making I6es... so Mercedes is just following them.  

    Regal, Lacrosse, XTS, XT5, Enclave, Acadia, Impala, Traverse, Fusion, Taurus, Flex, Edge, Explorer, MKX, MKZ, Continental, S90, XC90, CLA AMG45, RLX, MDX, Maxima..... off the top of my head... all have 300+ available horsepower in a FWD chassis..

    Almost all those cars are lousy.  You can put 300 hp in a front drive suv because they are so heavy it will reduce some torque steer but most of those 300+ hp  vehicles are all wheel drive and the CLA is a 4 cylinder with more power than the V6s on that list so you don’t need a V6 for a front drive car.  

    The other issue is that NA engines are becoming obsolete, everything is getting turbocharged and electrified to the point in the 2020s the vehicles with 6 cylinders will be large trucks and performance cars.  In addition I think turbo 3’s will become common place for small cars.

    None of those cars are lousy when they have 300+ hp.  Lousy are the ones with tiny displacement turbo 4s that get overworked trying to keep up. Yes, even my lil Encore is hindered by its power train.  I'll take a 300hp engine in it any day.

     Whatever vehicles the v6 goes away, i sure hope the replacement is as good.

    pentastar in our pacfica is so good, way better than the GMv6.

    i would love someday to have a turbo six.

    Because it is a weak turbo 4.  The Silverado even has a turbo 4 now, there is no need for a V6 in a family sedan, they just make the car front heavy and no faster than a good turbo 4.  And the CLA45 does 0-60 in 4.1 seconds of something in that range, that is faster than a V8 Lexus GS-F.  If GM put their engineering hats on they could turbo 4 stuff like the Lacrosse and Acadia, he’ll they have a non-turbo 4 in the Acadia now.  

    A six cylinder in today’s world should be nearing the 400 hp level.

    Great to hear.  I miss the straight 6 that was a staple of Jeep for so long.  I have always thought of straight 6s when I think of Jeep engines.

    Doesn't Mercedes have 6cyl in most everything? Isn't the GLA and CLA the only two vehicles that don't have a V6 right now?

    I loved and was not able to buy at the time the Jeep Eliminator Pickup truck with the HO straight 6.

    I put 170k on the 4.0 I6 in my Grand Cherokee WJ.  The engine was reliable overall, had oil leaks for years...

    :rofl:

    My daughters 1999 Durango with the 5.9 L V8 is awesome and runs so smoothly but after 323,000 miles even with changing them out the engine seems to leak oil since about 100,000 miles. Very weird, but leaks about 1/2 Quart between oil changes. So pan underneath and will just top it off till she decides what she wants to buy.

    After 17 years and 170k, my Jeep was tired...didn't want to spend any more on it..transmission was starting to slip, power windows and locks worked intermittently, air bag light came on on left turns..   desert life is hard on vehicles and people.   Didn't trust it on the 2000+ mile drive from Phoenix to Cleveland...the A/C wasn't very cold anymore either.  So glad to be done with the desert shithole..never want to be in Southwest ever again.

    GLA, CLA or any A-class/B-class is 4 cylinder only.  The Metris is 4-cylinder and any “300” model is 4-cylinder.

    400/450 models are Six cylinder and 500s are V8s.

      The COVID-19 pandemic has possibly caused another auto show to rethink their plans. According to Automotive News, organizers of the show are planning to delay the show from November to next May. Three sources tell the outlet the new dates are May 21st to 31st. Two of sources go on to say that an announcement could come this week.

      By possibly moving the LA Auto Show to May, automakers and organizers of the New York and Detroit shows find themselves in a difficult spot. The LA show sandwiches between New York (April) and the revised Detroit show (June), which may cause automakers to make difficult decisions as to which shows get the most significant unveilings or whether to attend at all.
      Auto shows in general have been struggling before the onset of the pandemic. With automakers deciding to hold their own events to have more time in the spotlight and save cash, the spectacle of the show has gone down.

      When Kia revealed the new Soul to the U.S. in 2018, they announced that the EV would be arriving sometime a year later. 2019 came and the automaker announced that the Soul EV had been pushed back to 2020. A few months later, the launch date was pushed to 2021. Now, an internal source at Kia's U.S. office has revealed to Roadshow that the Soul EV isn't coming at all.
      According to the source, a number of factors played into this decision. Some of the factors such as limited supply of batteries and motors, along with increased demand for the model Europe were used to explain the last delay. Also, the Soul EV has independent rear suspension. The standard Soul doesn't, which would make the EV more expensive to bring to the U.S. and add complexity. 
      Adding fuel to the fire, Kia has removed any mention of the Soul EV on their U.S. consumer and media sites. There is also no mention of the Soul EV on the EPA site. Previously, the vehicle was mentioned with a range of 243 miles.
      When reached by Roadshow, a Kia spokesperson said they haven't heard anything about the Soul EV being canned for the U.S., but did confirm they have "no pending plans to introduce before 2021 at the earliest."
      We'll keep you posted on this story.

    • Yellow - no (agreed) Orange - in rare instances Rust (metallic) - often very nice on the right car
    • Blorf.    About 5 yrs back my local Ford dealer had a bright yellow F-150 STX; it sat on the lot about 6 mnths cause no one wanted it.
    • My brother used to have a Chevy pickup that looked very much like this..he called it 'Big Bird'..
    • Always though it was the worst. I generally agree with your other points (no B-59 / big truck yellow-family, '70s GM 2-tone trucks look good). I liked the circa 2018 retro-painted SIlverados, and I would not have thought I would based on a verbal description.
    • '65-67 Corvettes, esp. convertibles look great in that pale yellow they had back then. Bright yellow was an iconic color for the '69-70 Boss 302 Mustang.    Today, bright orange or bright yellow seem to be popular on the GT models of Porsches and more exotic fare like Lambos, but I prefer Porsches in the more subtle colors, like dark brown or dark green...  The upcoming Bronco 2dr looks good in orange, at least in pictures..
