    To expand on this, I just spoke to one of my buddies who has a new F-150 with the start stop installed on his pickup. He claims it's not really noticable on his truck at all, and that says alot given how picky and anal-retentive he is about things like that. I suppose there is hope, but they are completely different drive trains so who knows.

    Do you doubt that I have done this? It is a requirement for Hairy Chest Hairy Chested Curmudgeons crew ...... if spotted passing or sitting near a Prius without gunning it, another member can pull your card.

    Again, it's not that big of a deal. Disable it if you don't like it. It will probably take about a second, maybe two, to reach over and push the off button.

    Two words:

    Active

    Exhaust

    I was once challenged with the question, "Where are you going to use 707 horsepower?", to which I curtly replied, "Everywhere I take it!" to a chorus of thundering applause (that is to say, laughter).

    The first time i saw a hellcat on the street he was going the other way. I was stopped a set of lights away and when he nailed it "it was like thunder" (lots of cloud cover that day) and i thought.... holy crap ! Needless to say mine was already ordered...

    In my opinion it's a good thing they're dropping the 6.4 SRT and working on a new HEMI. The challenger itself is heavy and adding 6.4 liters of displacement hurts even more. It is impressive however, that you can get low 4 seconds out of that thing, now that's the work of the HEMI. Hopefully the engineers can pull of something with a small amount of displacement but high output. I think a turbo 5.7 would be great and probably is the solution. I also hope and will probably see a more aerodynamic and lighter challenger to go with that.

    I was under the impression that the 5.7 was going to be replaced in most of the large cars while the SRT engines will live on with updates.

    I'm with you about the mandate, I'm for freedom of choice. But I am very interested in fuel economy, and would love to see a 50+ MPG Mopar being offered. I'm also super excited about the Pacifica Hybrid getting mid-30s MPG after charge is depleted. My beloved Neon averaged 34.5 MPG for the 370K miles I had it, and it's surreal that the Pacifica Hybrid can match it.

    I, for one, want more displacement and more power!!

    Yes, I was also under the impression from Bob's quote above that both the 6.4 and 6.2 SRT motors would survive for now.

    Correct. HELLCAT and Apache survive.

    Do we expect the start/stop to cross over to the charger/challenger in 19 with the ram?

    Is there any code name for the 3rd HEMI?

    Larger displacement does not mean greater weight. If I’m not mistaken, the new hemi is the same physical block in all its sizes. Additional weight to the car comes from additional cooling, larger brakes and wheels, and in the hellcat form, supercharger and required coolers. Adding turbos to the 5.7 would increase weight dramatically, and probably put in hellcat weight territory

    I believe the hemis motor mounts were chosen to accentuate the noise and vibration. Hopefully during r and d engineers will choose an active motor mount that will isolate much better during start/stop.

    6.4 correct? a lot of highway mileage to get that number? I saw about the same with a 5.7 Chally sitting in a ton of traffic and street driving.
