    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.

    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?

    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. 

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

    I had the Cherokee XJ with the 4.0L I6. it made an already good SUV even better.

    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.

    • Those that cannot accept a multi-cultural world and immigration deserve to lose everything. I will stay professional, but believe that our North American Economy is about to get far worse over the long term than it is now. It is amazing how people do not seem to realize that the first two years of a new president is dealing with the ramifications of the last president. The high inflation was due to the failed policies of those before. We now have low unemployment and a strong economy. Will be interesting to see how it ends.
    • I say, let it get worse.  The people have spoken and this is what the MAJORITY voted for.  He even got the popular vote.  Therefore the people of America have spoken.   This is what they want.  This is what they feel comfortable with.   But I dont want to hear ANY whining from ANYBODY about what possibly may happen with him Him in power.  Fool me once,  shame on you!  Fool me twice, shame on me?   Technically this is how that saying goes.  But you never know. Maybe it really IS the lefty libtards that are the problem.   Hopefully it IS the lefty libtards that are the problem and the Messiah Trump will BE the solution to ALL of our problems.   I will be the first one to apologize if He actually does fix America's and Canada's problems.  And unite ALL of the world and the world gets to sing Kumbaya ALL in unison. Hopefully He is the next coming of Christ.   Keeping my fingers crossed but I aint holding my breath if you know what I mean.   
    • @oldshurst442 This pretty much sums up just how bad it is going to get. Trump's economic plans would worsen inflation, experts say | AP News
    • Not just iPhones... He tariffed Canadian wood the first time around as Pres and the prices of wood skyrocketed so American home builders bought American wood which was and is more expensive than Canadian wood.  I guess that is good for American wood producers. But for the fact that house prices also skyrocketed.  And considering that Canada and US have a more or less good trading thing going on...so not that good.  Not for the US and not good for Canada.  But Donald thinks otherwise. And all the folk that voted for him this time around think that the economy will get better?  I hope so for their sake. But Elon and Jeff B's billions rose quite a bit upon the announcement of his re-election.  I wonder if those  people that voted for him, I wonder if their wealth also rose instantly?    You poor bastards... You have no idea what is coming to you... (those that voted for him.  With the excemption of the rich of course)     Donnie Rides Again
