    I actually think a roll up, consolidation, whatever, might not be too far fetched.

    Whoa! easy on the irrational exuberance ;)

    Y'know, I can see it now: Paul Revere, with his head poking out of the sunroof of that Chrysler 300C, yelling: "The diesels are coming! . . . the diesels are coming!"

    Just maybe there will be a hero for the domestics in this modern history, and someone will listen and be prepared. Regardless, those diesels ARE coming . . . from Germany . . . maybe later on from Japan . . . we'll see.

    But one thing is certain . . . The attack is imminent.

    With apologies to those who have tried to keep on topic, this discussion is taking a hiatus.

    The diesel and hybrid discussion simply does not belong here. And we are not here to continue to debate the etiquette of posting habits. I've addressed the former already, the latter is something that need not happen, but if it does, it certainly shouldn't become a running debate.

    We'll take a rest now. Everyone go take a nap. I'll wake you up when it's time for a snack. :)

    There is some milk and cookies over there on the table. If you promise to be good, you may have some. :)

    Welcome back. Let's try again.

    Cookie Monster says, "Yum yum . . . me love cookies. Thank you so much." :blush:

    Is there an official future replacement for the BMW 3.0 liter inline 6 cylinder engine? BMW has done miracles with their inlines, but is a V6 in the cards?

    Are there any ol’ goats like me who remember Froggy from the Andy Devine Show in the 50s?

    I seriously doubt that BMW would even consider replacing their vaunted inlines for a traditional V6. The M3 has already shown what the engine can do at 3.2L. I think they'll just make the next one larger. BMW would be more likely to resort to forced induction than to abandon the inline.
  • hpowdershpowders Posts: 4,269
    Yeah. Andy ("Jingles") Devine's show had the old Buster Brown shoe commercial.

    I agree with Lexusguy. The inline 6 IS BMW. That is one sweet engine.
    They may refine it, but I don't anticipate them changing to a traditional engine.

    If you have the length, an in-line 6 is inherently balanced...capable of high rpm and minimal vibration. In contrast, a v6 is much harder to balance - it requires extra parts or much larger harmonic balancers.

    "Is there an official future replacement for the BMW 3.0 liter inline 6 cylinder engine? BMW has done miracles with their inlines, but is a V6 in the cards?"

    I'm thinking that given that there is a brand spankin' new from the ground up redesigned I6 in the E90 and E60, the suggestion that BMW might move to an inherently unbalanced V6 anytime soon (if ever) is highly, highly unlikely. True V6s can be smoothed out with the application of high speed balance shafts (a misnomer if there ever was one as "balance shafts" are themselves highly unbalanced), but at their very best they'll never be as smooth as a completely unadorned I6. Why? Simple, because the I6 engine configuration holds all mechanical inertial forces in natural balance at all times (the H6 and V12 configurations do too). All a "balanced" V6 can do is approximate a balanced condition by spinning unbalanced stuff at high speeds to try and cancel out the natural imbalance of that engine configuration. The problem here is that the balancing devices employed are installed in such a way as to balance the average of the imbalanced forces, and as such, are typically only perfectly balanced at one specific RPM.

    When engines are tested for mechanical "balance", there are four different measurements typically performed (I say typical because Radial back in the WWII era were measured and balanced to as far as the sixth order), and they are as follows:

    - Free forces of the first order (i.e. once per rotation)
    - Free forces of the second order
    - Free movements of the first order (i.e. twice per rotation)
    - Free movements of the second order

    Naturally balance I6, H6 and V12 engines score a perfect zero in all four of the above categories, however, an even firing V6 (natural firing V6s are even worse) suffers from significant Free movement forces of both the first and second order.

    Hmmm, wordy enough; suffice to say, BMW has staked its place in the automotive world as the last manufacturer of I6 engines in the world. I don't see that changing anytime soon.

    I go away for a couple months...and return to...familiar names and cookies on the table. Makes a man feel comfortable. Hey... Did anyone attend the Chicago Auto show? What else is new?
  • You mean as in "Pluck your magic twanger Froggie!! BOING!!BOING!! Hi ya kids, hiya hiya!!

    A couple of things, actually. It looks as if Acura is abandoning touch screens for center stacks in the same vein as the RL's. Here's what the inside of the RDX looks like.

    Another interesting development, and one I would definitely like to hear Mark's thoughts on is that "Audi will terminate their free maintenance on all 2007 models.", according to Autospies anyway.
  • The latest on the Audi is that indeed they may do away with the free maintenance for new vehicles, but will allow return buyers to extend their free maintenance as a type of loyalty payback...

    The BMW 545 rocks with its superb 4.4 liter 325-hp 32-valve V-8 engine.
    However, after also driving the inline 6 for 12 years, I have to say when the power factor is taken out, I do prefer the inline 6- a little smoother, believe it or not.

    On another note, while you were watching the AD show with its hand-puppet, Froggie,
    I was tuned into Jon Nagy's Learn To Draw show.

    I believe it! Dude, you must have one seriously sensitive Butt Dyno because according to the "Internal-combustion engines" chapter of my handy-dandy Automotive Handbook, V8 engines suffer from a very small Free Movement of the First Order. I'm impressed. ;-)

    I could not have said it better myself!

    The BMW i6 is a World Wonder in the automotive industry.
  • I agree about the BMW i6. You would think some of the other companies would catch on.
