Replying to: sfcharlie (Jun 24, 2006 5:10 am) obviously, I did not have a dB meter with me, so my assessment is subjective (how loud did it seem?). From most road noise to least, they were RL (Hondas all seem to have this problem), M35X, A6 and GS. The GS was by far the quietest, but to me, was the least "fun" to drive. OEM tire selection clearly is an issue here too, but so is suspension tuning, bushings, etc. Again, all seemed to be excellent cars, but I think it is too bad that some manufacturers seem to make so little effort to deal with interior noise. Cranking up the radio volume to overcome the racket from the tires is unfortunate.

Replying to: sfcharlie (Jun 24, 2006 5:10 am) It is the sound proofing they put in the wheel wells that rids the vehicle of excessive road noise, I drove the RL with the radio on to allow the noise canceling system to work and the vehicle was just as quite, they use this new system to get rid of the excess weight, also the others cars don't have the saftey cage the Acura hase which contributes to the solid feel of the vehicle.

Look on Edmunds (http://www.edmunds.com/insideline/do/News/articleId=115914) and also on the Infiniti site. Bottom line, not much change, still a 5 speed automatic and AWD only on the M35. Limited options in LPS if you want AWD and 8 cylinders. Replies to this message: lexusguy (Jun 27, 2006 7:38 pm)

Replying to: sfcharlie (Jun 24, 2006 5:17 pm) Maybe it's just me, but the louder at full throttle acceleration, the more I like it. Especially if the loud sound has the proper tone. VRrrooooommm..... Replies to this message: james27 (Jun 27, 2006 2:39 pm)

Replying to: purplem46 (Jun 27, 2006 12:50 pm) While a weighted sound pressure measurement does account for the frequency, it is not a lnear effect nor is it affect how one perceives the sound (there are at least a few scales, A and B are two). In other words, two cars could have identical measured sound pressure levels, but one could sound "good" and the other could sound "bad". The definition of good and bad is up to the listener.

Limited options in LPS if you want AWD and 8 cylinders.   No one expects major changes when a car has only been around for a year. I dont think Nissan has a 6-speed auto, but I'd rather have their rev-matching 5-speed tiptronic than many of the 6-speeds out there. Infiniti originally said there wasnt enough space for the V8 and the AWD gear, so I wouldn't expect an M45x any time soon.
#7648 of 10007 Audi Commercial by aflc Jun 28, 2006 (10:19 pm)
I've been seeing a lot of Q7 commercials lately. The most I have ever seen for an Audi in the past few years. It's on almost every channel and I see a few every night. Before you would be lucky to see one on anything besides the history channel, and those were pretty limited too. I wonder if they need the extra boost with gas prices out of control.   I wish the people in the marketing group would have thought about spending a little money and had given the A6 a little more air time when it first came out. I don't think anyone knew that a new A6 model was even out there. Replies to this message: markcincinnati (Jun 29, 2006 4:02 am)

Replying to: reality2 (Jun 23, 2006 5:45 pm) Audi has improve their quality alot since the 80s, my 2k A6 is like day and night compare to 5000CS (1987) and 90CS (1991). Its been trouble free. On the other hand, our 1998 Lexus GS400 has as trouble free as our 1990 LS400. Maybe its the first year in that second gen, but Toyota/Lexus dont make cars the way they used to with the Cressidas (1986 and 1989). Still, looking in to GS430/460 or the IS350, hoping they improve since the GS.
