    The Maserati GranTurismo and Quattroporte are currently powered by Ferrari V8s but if rumors prove to be true – the next generation of these models could feature the same Pentastar 3.6L V6 used in almost every current Dodge brand product.  The key difference is that when the Pentastar finds its way under the hood of these Italian exotics it may pack a pair of turbos – pushing the output of the Pentastar well beyond the numbers seen in the Dodge lineup.


    While a twin turbo version of Chrysler’s Pentastar V6 serving as
    a proper engine for an Italian supercar may seem farfetched, I recently
    had a chance to chat with an insider with some interesting
    information.  My source told me that since Chrysler engineers finished
    the 3.6L Pentastar V6 pre-production testing procedures prior to hitting
    the showroom, that the mighty little motor under the hood of the Dodge
    Avenger, Charger, Challenger, Durango, Journey and Grand Caravan has
    undergone intensive high performance testing.  He explained that the
    Pentastar has been tested in a variety of forms, all making well over
    the factory output of any current Chrysler Group models, most
    importantly and interestingly, including a twin turbocharged variant.

    informant would not go into too much detail, but he did comment that
    the twin turbo Pentastar has made enough power to easily overpower the
    Ford EcoBoost found in the Taurus SHO.  In that application, the
    EcoBoost makes 365hp and when I pushed the source a little more, he
    suggested that the 400 horsepower range is not out of the question. 
    However, when this information was offered to me, the rumors of the next
    Maserati models featuring twin turbo Chrysler V6 engines were not yet
    public, so the news of a boosted Pentastar seemed a bit odd.  Now that
    these Maserati rumors have surfaced, the discussion of a twin
    turbocharged Pentastar being tested seems to make a tremendous amount
    more sense, while at the same time working to support these Maserati
    rumors.

    The 3.6L Pentastar V6 makes between 283 and 305
    horsepower in the Dodge lineup, depending on the model in which it is
    fitted, so getting 400hp out of this compact engine shouldn’t be too
    much effort for the engineers at Chrysler.  Like the Ford EcoBoost 3.5L
    V6, running a low-boost twin turbo setup with the other modern engine
    technology already included on the Pentastar V6 should push the powerful
    Chrysler V6 into or past the power range of the Ford EcoBoost.  That is
    all well and good, but if these Maserati rumors prove to be true, the
    twin turbocharged Pentastar will need to compete with much more powerful
    models than the likes of the Ford Taurus SHO. And once Chrysler has
    designed this high performance variant of the popular new engine – how
    long will it be before this engine ends up under the hood of an
    American-sold Dodge vehicle?
