    I was thinking that you should be able to arrange with your dealer to have them swap the 17" wheels with the 16's if you think the 17's are too much for a sedan. This way you get the firmer ride, lowered suspension, and fabulous seats in a more conservative-looking package. I love the 17" wheels but I can understand it if a more mature person thinks they are too much. They dealer should be willing to do it, as you are essentially trading more expensive wheels for cheaper wheels. BTW, the '02 330i is getting the style 44 wheels - same ones from the '01 325i SP and the 325ci SP. Obviously, there are a lot more people out there who think that the style 44 wheels are great looking.

    I live and drive and 6-7K feet. Octanes offered
    in this part of th country are lower than what's
    found in Houston for example.

    On my first test drive of 3-Series here in
    Albuquerque, the salesman specificly stated that
    all their vehicle used and were filled with
    regular 85 octane. When I pressed him about what
    the factory recommended he still insisted that
    regular was adequate and the dealer stood by that.

    You're right -- inertia does not vary with velocity (independent of velocity). What I should have said is that momentum ( = mv) becomes less sensitive to mass as velocity increases. The higher the v, the less m contributes to momentum. So a 1500 kg car at 1 m/s has 100 kgm/s more momentum than a 1400 kg car at that same speed. However, at 100m/s, that same car now has 10,000 kgm/s more momentum than the other car -- all due to the change in v. This is also why cars' rates of acceleration decrease with increased velocity -- constant force (roughly) applied to a constant mass, but more momentum to overcome. Not to mention other factors that increase (some exponentially) with speed, such as wind drag and other frictional forces.

    Which is why we should all use the minimum octane that the engine is designed for (91 for 3ers, I believe)...
  • Not absolutely sure, as this waiting has become a blur for me--translation, everything seems just plain too long. It was slated for June 1 production or thereabouts, so it looks like it's pretty much on schedule.
  • I can't even remember when I placed my order, somewhere at the end of April. If yours went into production status that early, I'd say you bought the guys in Munich some very good beer. I feel like I've been waiting forever.

    I see what you guys mean. At increasingly higher speed, the same absolute changes bring less relative changes, right? Example: adding 1 to 2 is a 50% difference. Adding 1 to 50 is only a 2% difference. The higher the speed, the less the acceleration difference due to weight between otherwise equivalent models because we are working with smaller relative changes. It's that simple.

    I've seen several spy-shots of the upcoming 2002 3-series, but today on bimmer.org, I found a full blown frontal shot. Is this the M3? Or is it really a 330? Can anyone enlighten me?

    I think your car might be a south african build. I hope not...that would mean a couple extra week delay. Did you ever get a response back as to what the N on the VIN meant?
  • burrsrburrsr Posts: 255
    Yes, that is correct in a simplifed way of looking at it. I'm just glad to be able to APPLY this stuff after 10+ years of learning it...

    So, have we figured out the optimal octane rating for our 3ers? If it's 91, then I'm pumping in a couple octane ratings too high and wasting a couple dollars/month in the process. I don't care about the extra $5/month, but I DO care about engine longevity and performance optimization! Is it 91 or 93??? Shipo -- you seem to be the most knowledgeable about this topic -- any further insights?

    I figured BMW would eventually decide to switch back to the style 44 wheels for the 330. I wasn't going to order the SP on my 330 because the sport suspension was standard and I preferred the 4-spoke steering wheel of the non-SP. However, when I saw those hideous radial wheels on the non-SP 330, I decided to order the SP for the M-double spokes. The radials are a pain to keep clean.
  • I'm not too keen on the new styling, if that is, in fact, the way the new 3 will look. It changes the very things that don't need changing. The grille looks bad with the pointy outer corners. The previous kidney bean grille was perfect. This photo also shows a front-heavy and bulbous front spoiler w/ the fog lights moved up to the actual bumper. I don't think it looks very cohesive or attractive. It's the answer to a question that nobody asked.

    I am taking my 330i into the shop this weekend for its 15k service.

    I love the car and I don't think I have any problems with it, but the more I think about it, I think I could.

    Anyway, I've driven standards for 10 years; honda, nissan, mazda, ford... All of them have been easier and much smoother than the BMW. I am not sure if it is because it is rear wheel drive or what, but when I shift, the noise is loud, like a clunk and it is rarely smooth; at least from 1st to 3rd gear.

    So, this gets me thinking... is this normal? I don't remember the car I test drove to be that "rough", but it has been 9 months or so.

    I have read comments where people have said the car needs to be broken in, etc... and things only get better. Well, 15k miles later and mine doesn't appear to be getting better.

    Not only that, but does anyone have a hesitation when pressing the accelerator? Sometimes, the car just doesn't want to move. Where is all the power?

    Okay guys (and ladies) help me out here. Am I paranoid? I'd like any suggestions so that when I take the car in on Saturday I can speak to the service advisor with some knowledge of what I am talking about.

    Suggestions are welcome... appreciate it.

    Thanks,
    Stacy

    Please explain why you all own the 3 series over the 5 series?

    Thanks.

    emilyk - this is not the M3 - it does not have the distinctive M3 side vents. I can believe it is the new 330i. Well, let's see what the changes are: same color molding for the sedan, fresher grill, halo lights from the 5-series, better-looking wheels - yeah, a few cosmetic changes to keep it looking fresh. It's nice but it looks a lot more like a downsized 5-series and it is les distinctive that way. I would not wait for it if I were to buy right now. Not unless there is a substantial discount over the '01 MY models (very unlikely) and you can get the same dealer discount as on the MY models (even more unlikely). You are saying "back to the style 44 wheels"? I didn't know they used the 44s on the 330 in the past...

    Brave1heart: I don't know enough about Dinan, but my dealer reccommended the Dinan mods. He said any other type of mods would void the warranty. The mods that were on my previous cars were: Performance Choice Cold Air Induction, Hypertech stage 3 chip, and the Flowmaster 2 chamber muffler Cat-Back Exhaust System. 2 chamber mufflers are loud and agresssive and are less restrictive. 3 chamber mufflers are deep and mellow and a little more restrictive, but add alot more airflow compared to a factory muffler, way more!. Music? The first CD I popped in was Yanni and John Tesh, with special guest Kenny G! Then "Who Let The Dogs Out!" (just kidding). First song was Pat Metheny's "Are You Going With Me" from one of his live albums that I downloaded off of the internet. Then Linkin Park for some updated hard rock. Then the 80's hits radio station. Hmmm.. The 80's... The land of pastel clothing and Pac Man, but it was alot of fun! :o)

    I asked the same question of both my dealer and BMW North America. Both said that while the car WILL run fine on 87 octane, long-term use will probably adversely affect the engine. The dealer also told me that some people think they can use 87 octane most of the time and then add a tank of 93 octane once in a while to "clean" out the system. Bad move. Apparently doing this messes up the catalytic converter and causes strong hydrogen sulfide type fumes to back up into the interior of the vehicle. He also told me that the car IS actually spec'ed for 91 octane, so 93 is really something of an overkill. Said 89 octane (mid-grade) is a good compromise and is close enough to 91 to allow the car to run well with no danger of engine damage.

    That said, however, I do remember reading a post a while back stating that use of 93 octane does increase fuel economy, so it might just be worth spending the few extra cents per gallong after all.
  • Well, some of us have a car spending budget (like me). Others may like the styling better. I also chose the 3 b/c the 5 doesn't have a coupe version. But, again, it's mostly about price, I think.

    "Anyway, I've driven standards for 10 years; honda, nissan, mazda, ford... All of them have been easier and much smoother than the BMW". ?!?!?!?!?!?!?!?!?!?!? I am afraid I can't help you here. You should sell your 40-grand Bimmer and buy a honda, nissan, mazda, ford. Your boyfriend might be happier you got rid of that overpriced, underpowered German car.
    As far acceleration, there isn't a whole lot of it under 1,800 RPMs - you should specify what RPM level you feel that at.

    I recall that BMW used the Style 44 wheels on the 328 of years past, however I could be mistaken.
