    Wouldn't just adding some turbos or a supercharger be a lot easier? Its not as if the 335 engine is anything more than the 3.0L with turbos on it. It seems a little silly to transplant an entire engine for just that. Since overall displacement is the same though, I don't see how the 335 engine could have any trouble fitting in the space large enough for the 540i and M5.

    Trust me, it's WAY more complicated than a simple blower installation. Consider the following points:

    1) The engine in the 2002 E39 was the previous style (and in fact many years old in its life cycle) aluminum block with the cast iron sleeves. Decent for its purpose, but hardly as robust as the new aluminum core/magnesium shell composite block that debuted with the introduction of the E90.
    2) Factory built turbocharged engines are typically reinforced (over that of the normally aspirated siblings) with the following goodies:
    - 2a) Higher strength crank, rods and pistons
    - 2b) Rod based oil squirters to cool the piston domes
    - 2c) Considerably greater cooling capabilities such as:
    - - 2cA) Larger radiator and the necessary plumbing
    - - 2cB) Additional and/or larger oil coolers and the necessary plumbing
    - - 2cC) Large size intercooler(s) and the necessary plumbing
    - - 2cD) Extra coolant plumbing to the bearings on the turbine houseing to keep them cool, especially at shutdown
    - 2d) Significant software remapping
    - 2e) Revised/more robust valve train
    - 2f) Higher flow intake and exhaust manifolds (2 in the case of the 335i)

    Did BMW do all of the above to the 335i engine? Probably. Would I trust the (bored out to within an inch of its life) 3.0 liter mill from an E39 to withstand the rigors of a 300 (320-340 by all accounts) HP turbocharging application? Not a chance. While the old 3.0 liter mill was certainly a good and robust engine for its intended output, there is only one word to describe what would happen to that engine when an intake charge 150% of design spec was fed into it. KABOOM! ;-)

  • Ray,

    After reading your post, I went to the BMW USA web site under Future Vehicles and read the overview and press release on the new 5 series.

    Does the press kit you mentioned have any additional information than the web site?

    In the overview, when describing the 550i sport package, they say " ... new 19” double spoke alloy wheels (non run-flat) ... " Does anyone know if this implies that versions other than the 550i SP will have RFTs?

    Thanks
    Bruce

    So far, I have only seen a batch of additional photographs - that I do not yet see on the web site.

    Semi-happy with my run-flats....

    An engine doesn't have to be made out of exotic metals to handle some serious boost. Take the Toyota 2JZ-GTE for example. Its an iron block, aluminum head SOHC straight six that dates back to the early '90s. Hardly state of the art. Normally aspirated it made 225hp. With twin turbos, it could do 500hp without serious modification. I know the S2000's engine can do well over 300hp with just 2.2L, and Honda did not design it with forced induction in mind.

    "An engine doesn't have to be made out of exotic metals to handle some serious boost."

    Agreed, however, the old BMW engine was more than a little long in the tooth. Comparing an iron block Toyota mill or or the very high revving S2000 is rather apples to oranges. I've never torn one of the old 3.0 liter BMW engines down so I cannot speak from first hand knowledge, however, as I understand it, its been bored out to the point where keeping three hundred plus HP contained would be more than a little hard on head gaskets and such.

    Regardless, even if I was playing with one of the new mills I still wouldn't breath on it without a serious internal rework, including a lower mechanical compression ratio. Long story short, the only real way I'd ever attempt this would be to find a totalled 335i with the drive train still intact. Realistic? Probably not. :-(

  • I want 535d xi
  • shiposhipo Posts: 9,152
    A 6-Speed 535d SP (sans "x") sounds great to me too, especially given that I'm driving nearly 100 miles per day. That said, given the 300 (plus) hp on tap from the twin turbo gasser, oooh, I'd have a difficult time passing that one up. ;-)

    I read that the 535i will be here in March!

  • The Audi was app.$7200 more similarly equipped. Audi had a lower MF. Infiniti had a slightly higher residual.

    GUESS WHAT!!!!!!!
    Audi is now offering a $2500 owner loyalty on A6's until 3/5/07.
    36/12 50% res. .00027 MF. Added in Audi maintenance for $550 which raises res.1% to 51%. Added 18" wheels and ordered a blk/blk. May miss the acceleration of the M but there is someting about the "planted" secure feeling of the Quattro Audi that I wanted. With the wheels($900) paying $app.$%5 month less than before.
    I'm excited!!!!!!

    I can see why some would prefer the G's interior styling over the M's. I think it is a little more sporty. However, from the quality and texture of the materials, the G isn't even close to the M.
  • Hi, Told my dealer about the lease terms you mentioned. They said they do not know anything about an owner loyalty program for the A6. Do you have a link or source? They also told me MF was .00042. They must be looking to close the deal because last Monday the MF was quoted at .0014. However, while MF is down they say residual is 49%, down for 50%. (A6 3.2Q 36mo/12k) I don't think I believe that. Tough keeping up with these guys.
  • Interesting post, LexusG. I also own an older A6 (3.0, 2002), and just returned from testing the new one. Did not like it much. I felt that the new A6 was too noisy, and provided less visibility than my older Audi. I still loved the interior and technology in the Audi, but did not enjoy actually driving it as much as driving the old one. Unlike many people here, I like a quiet and soft ride. Not too interested at "feeling the road". I just tested the Lexus ES 350 and enjoyed it. Feels like lots of car for the money. Following other discussions here, I would want to try the Infinity and see how that feels.
  • Late April/early May my dealership says. They are taking orders, but they don't have pricing yet.

    In terms of creamy isolation from the outside world, the ES does it better than any other car under $65K. If by Infiniti you mean the G or M, I wouldn't bother. They are about as far on the other end of the spectrum as you can get from the ES; raw, mean sports sedans. My suggestions for other cars to consider would be the GS350 AWD, and Volvo S80 3.2. The Toyota Avalon also has most of what the above cars have, for a lot less money. The Passat is also worth trying.
  • WOW.

    I had the following (not a complete list):

    1995 S6
    1997 A8
    1999 A6 2.8
    2000 A6 4.2 comfort
    2001 A6 4.2 sport
    2003 allroad 2.7T
    2005 A6 3.2 with 18" wheels and 245 x 40 x 18" tires

    At the same time, my wife had multiple A4's, three TT's and one BMW X3 3.0.

    The A6 is the quietest of the bunch (including the A8), it also is both more compliant and able to corner better than the 2001 sport version of my A6, which I assumed is due to the its greater, by far, chassis stiffness.

    I tested, thoroughly, the Infiniti M35X and the Cadillac STS and have rented, repeatedly, competing lux and/or sport lux cars from Europe and the US. I rented, too, a Lexus and participated in a test with Car and Driver that included the new Lexus cars.

    Lexus cars are the most quiet. Audis and Cadillacs are second and the Infiniti is third. The BMW's I have tested and or have in my garage at this moment are hardly loud, but they are the loudest of the bunch -- due perhaps to the choice of tires they come with.

    Perhaps you drove a new C6 Audi with 19" wheels and tires and the S-Line package. This version can be noisier and I assume it is entirely a function of the wheels and ultra low profile tires (with extra stiff sidewalls.)

    The ride of the Audi IS firm, but it is also shudder free and able to telegraph the road to the driver.

    The Lexus seems to me to be as comfortable and quiet as the Cadillac DTS, and able to handle better -- but the Cadillac on a smooth road at 80MPH remains like riding on your living room Barcolounger -- and even the Lexus doesn't do that.

    Thank god.

    I urge you to test Audi A6 again -- unless for other reasons you have totally ruled it out -- and other than this suggestion: ask them to make sure the tires are properly inflated -- well, it should be quite smooth,compliant and quiet. Moreover, it should handle very well, certainly better than the Lexus and Cadillac models it competes with.

    Wow. :surprise:

    Great point. First time I test drove the 07 A6 I thought it would knock my teeth out. Asked the dealer when I got back if the car really was that stiff. He apologized and said the cars come off the truck with 50psi and he had forgotten to adjust. Since then, I always ask if the inflation has been checked...it usually has not or they are left at 45psi so the tires don't get "flat spots" sitting on the lot.

    I'm still hoping that Audi comes out with a lease program for the A6 so that it is not more costly then the 530xi. If they wait much longer, I will have to wait for the 535x.
  • Tell your dealer to read his bulletins. It was sent out last Monday and expires 3/5/07. It was shown to me by the NJ dealer and the New York dealer was aware of it. The MF is .00027 and the res. did go down to 49% for 12,000 miles however if you take the Audi care for $550 the res. is increased by 1% to 50%. I gave NY dealer a deposit for a blk/blk. There isn't enough time to order to receive before my current Audi lease expires. Premium, convenience, technology, heated steering wheel, 18" wheels and Audi Care.

    Good Luck,
    J
  • Thanks, LexusG...I will check out the Volvo. I'm sure Avalon is similar to the Lexus, but I prefer the extra conveniences offered by the Lex.

    Didn't realize that the Infinity's ride was harsher..may still worth looking it. Bottom line, these are all good, capable cars, and it all comes down to subjective preferences.
  • Wow, you're obviously a loyal Audi driver....I can understand that my "heresy" affects you. But, in my case, I'm more loyal to my buns, than my brand....
