Acura RL

    I went looking through the pics for the Ody and they have a torque curve there. None for the RL, though.

    Yeah, cars are getting heavy. I suspect that making them safe in a crash, silent on the road, and filled with goodies is simply one too many goals for a featherweight. But I was hoping that the use of aluminum subframes would have kept the weight under 3,800.

    add another 1/4th pound... lol

    Robertsmx, dude, you rule.

  • 1) Weight
    2) Mileage
    3) Turning circle

    Accord Hybrid anyone?
  • It appears based on the descriptions I've been able to find that the RL doesn't have split fold rear seats - just a pass through.

    I was watching the RL with interest, but now it just dropped off my list for consideration. I don't understand why Honda isn't putting them in... The TL also became a non-starter for the same reason.
  • Messages 2019 and 2020, posted in the early morning hours of Sept. 1st, reference new content regarding the 2005 RL on the Acura web site. As of 9:00 pm EDT, same day, that content has been pulled, or the web site is malfunctioning. Although the RL prototype button is now gone, the new 2005 RL button only takes you to info on the NSX, MDX, and RSX, and the regular 2004 RL data remains. Were some erroneous specs published, I wonder, and subsequently taken down?

    I had the same problem trying to use Firefox browser. Tried the site with Internet Explorer and it worked fine. (Make sure pop ups are NOT blocked.) Its basically a mini-site for the new RL.

    Sidenote - the interior is stunning. I want this car!

    Robertsmx -Based on your various calculations on torque, gearing, drive ratios and your propensity, for the most part, for being "right on the money" - Given the RL's drag coefficient of .29, and weight of 3,900+ lbs - what do you estimate is the RL's top speed?
  • robertsmxrobertsmx Posts: 5,525
    Thanks shotgun/ksoman.

    Thats hard to figure out. But I assume it may be around 150 mph. I believe someone tested TL at 152 mph, not sure who. RL may match that.
  • Carmakers consider folding rear seats too utilitarian for their top-line luxo class cruisers and unbecoming of their image. They offer the ski opening as a concession.

    BTW, while it's interesting to read all the technical prose about the weight, turning-circle, gearing, etc. about the new RL, I'll base my judgment on an extended test drive putting the car through its paces.

    I expected a weight increase with the addition of the SH-AWD system, so the "porkiness" of the '05 is a non-factor for mr.
  • I just went to Canadiandriver website and they had a news post saying Acura Canada has just announced the MSRP for the new 2005 RL. It apparently has jumped from C$55,000 for the old 2004 to C$69,500 for the brand new 2005. That seems a very large jump even taking into consideration the significant amount of improvements in the 2005 version. We are talking about Lexus territory here. In fact, for C$70,000, you can alomost get an Audi S4. I thought I would get one of these new RLs but if the price is indeed correct, I am leaning more towards an Infiniti M45 or FX45 now. What do you guys think? I don't think Acura US has announced their pricing yet.

    I have fold-down rear seat in my BMW 540iA (for extra few hundreds buck as an option). For one thing, I have never have an occasion to use it yet (my Odyssey took care of things). For second, I believes it compromises structure integrity (specifically, torsional/bending rigidity) by roughly 5-10% (due to lack of cross members that could be placed there).

    I guess I can do without one. Just MHO. That turning circle does bother me. In California, there are many tight U-turns. My friend's RX300 with 44ft proves hard to negotiate tight U-turns and parking spaces.

    robertsmx, great posts on the gear ratios.

    I see that on their web site they now show EPA highway as 25 - vs. 26 on the press releases dated 1 Sept.

    Still "based on internal testing".

    Looking at a couple of roughly comparable (nothing will line up exactly regarding size, HP, equipment, etc.) AWD sedans, I see the (2004) A6 4.2 300 HP listed at approx. 4000# and the Passat W8 (I happen to have owned one) at just under 4000#.

    I do not think that the published RL weight is disappointing.

    And I do not think that the EPA highway numbers (26 or 25) are disappointing.

    If one requires (or desires) AWD, there are trade offs. One is the additional weight and parasitic drag of the additional drivetrain components.

    - Ray
    No longer looking at AWD as a requirement . . .

    I guess "porkiness" was too strong a word. Still when compared with cars like the BMW 530 and G300, the RL comes out roughly 400 lbs heavier. Adding AWD will account for 200 lbs, making the difference much smaller. That's very true. However, given that Acura wants to stay with a V6 only, I would think that weight would be a larger concern for them than other manufacturers.

    Robertsmx - I've been thinking about your formula. At it's core, it's simply power multiplied by mechanical advantage, then divided by factors of resistance. But I've got a question about the tires. In your equation, you use the circumference of the tires as an indicator for their resistance to the power of the engine. What about the mass of the tires?

    I would think tire mass would also be a factor, though I cannot for the life of me guess at how significant. Have you got any links on the subject?

    Thanks in advance

    Dear Acura,

    If your reading this, and I know you do since you've posted Edmunds comments on your site in the past.

    Please add the ability to ask for the time using the voice command.

    In our 04 MDX 189, the clock is so far down the dash that you have to look away from the road for 2 seconds just to see the time.

    Having the clock adjust for daylight saving time would also be a plus.

    thank you.

    Varmint, mass of wheel will not play a role in affecting the overall gearing (hence thrust or the max speed in each gear). It will, however, contribute towards drag/rolling resistance and weight of the vehicle, besides handling.

    I have had the set of formulas I quoted for several years now, and have been playing with them. But I’m sure a web search could lead us back to the source.
  • l943973l943973 Posts: 197
    I can't believe the 05 RL still has a 4-way power passenger seat! That was one of my grips with the current RL. Hopefully they will have a touring package like the MDX to fix this problem.

    How come the rear headrests can be powered down but must be manually raised? Most folks that sit in the back NEVER raise the headrest.
  • ksomanksoman Posts: 593
    Oh the RL looks good in the darker colors.... Now if only the US side of the Acura company becomes brave enough to move away from the 100s of shade of silver, champaigne & white & black that they offer and actually offer some nice deep dark colors...

    but i bet their entire line up for the next 10000 years will always be these ridiculous boring silvers, golds & shades of gray...

  • ksomanksoman Posts: 593
    the edmunds review of the 2005 honda ody is out. how far behind is the RL...

  • rayainswrayainsw Posts: 2,935
    Anyone heard when US pricing is expected to be released?

    I prefer black/dark blue tones. But the fact is, silver (or shades of) is the best selling color in the USA.
  • IBM Delivers New, World-Class In-Car Speech Recognition System for Navigation in 2005 Honda Cars

    (From: Auto-Tech 2004)

    SOMERS, N.Y.--(BUSINESS WIRE)--Sept. 1, 2004--

      IBM's Breakthrough Embedded ViaVoice(R) Technology Recognizes Street Names; Solution Bundled with Real-Time Navigation and Zagat Survey

    IBM(R), the world leader in information technology innovation, today announced that it has jointly developed with Honda Motor Company a unique, hands-free and natural-sounding in-vehicle speech-recognition system - the industry's leading-edge navigation application. Honda will offer the system as standard equipment on the 2005 Acura RL and as options on both the 2005 Acura MDX and 2005 Honda Odyssey in the United States and Canada beginning this month.

    Using IBM Embedded ViaVoice software, Honda is the first car manufacturer to equip automobiles with in-car navigation systems using advanced speech recognition and text-to-speech capabilities that can identify spoken street and city names that exist across the entire continental United States. This allows drivers to speak all street addresses represented in the US navigation system database and receive turn-by-turn voice guidance to their destinations. The breakthrough voice-recognition system can also enable enhanced ease-of-use by eliminating the need for drivers to take their hands off the wheel or eyes off the road, since no typing on touch screens or manual dialing is required.

    To create this advanced, natural-sounding text-to-speech system, IBM and Honda research-and-development teams digitally processed hundreds of hours of speech recordings previously found in earlier-model Honda systems. They also produced hundreds of additional recordings to design a high-quality, customized, natural-sounding text-to-speech voice, digitally segmenting speech and intonations that can allow vehicles to communicate naturally with their drivers. The result: a totally new type of speech synthesis that can capture the characteristics of the human voice. In addition to the natural-sounding text-to-speech, the Honda Odyssey, the Acura RL and the Acura MDX now feature more than 700 commands and more than 1.7 million street and city names that are accessible by voice.

    Another unique system feature is nationwide dining information from Zagat's Survey, which provides drivers and their passengers the ability to request the names of, and directions to, nearby restaurants and also listen to or view restaurant reviews.

    Besides its advanced speech recognition capabilities, the 2005 Acura RL comes equipped with the first real-time traffic navigation system in the United States, which integrates real-time traffic data into the navigation display. Other integrated features include:

    -- AcuraLink, which communicates information between dealers and drivers, and

    -- HandsFreeLink, which uses BlueTooth technology to synchronize personal cell-phone data within the car environment; this provides drivers hands-free, speech-enabled dialing on phones with built-in BlueTooth capability.

    IBM's voice-recognition technology is integrated into the car's audio system so that driving instructions can be heard over the speakers. Alongside its navigation functions, the system also provides command-and-control capabilities for audio, DVD entertainment system (Odyssey) and climate control functions.

    Honda and IBM, using IBM Embedded ViaVoice, have deployed leading-edge voice-enabled telematics solutions since 2003. User satisfaction with the Voice Recognition-enabled systems has been outstanding due to Honda's engineering ability and the strength of IBM Embedded ViaVoice's speech technology and automotive telematics solutions.

    The new Honda navigation system is the latest in a broad portfolio of in-vehicle solutions that combine IBM's pervasive computing technology and telematics know-how. Software and electronics comprise a rapidly growing percentage of innovation and differentiation in cars today. IBM's integrated, open-standards-based software and telematics solutions are increasingly allowing data to benefit customers virtually wherever they are, helping to create entirely new industry models.

    "Drivers can now fully access the majority of the resources inside the navigation system with voice input" said Tom Elliott, executive vice president of American Honda Motor Co., Inc. "As in-car navigation systems evolve and become more commonplace in today's vehicles, our extensive voice-recognition features give Honda and Acura products a distinct competitive advantage."
  • Thanks for the link. That's exactly what I was hoping for, but I'd given up on it being that sophisticated.
  • Will the American version (RL) be identical to the Legend (Japanese version)? I assume it will be -- minus the rear badge.

    From the side, the car looks like a glorified Accord. It seems to me that it's the Honda Accord that is back. Hard to believe that after all these years this was the best that Acura could come up with for the "new" RL.

    Clearly, most of what is new and exciting is INSIDE the car, and not on the outside. But hey, that's just my opinion .. your mileage may vary.

    I have a similar feeling couple days ago when I went to the interactive showroom at acura's web site.
    Strange speaking, I still do know how my accord v6 looks like exactly after 3 years. I guess all I do is get into the car and drive it and get out of the car and the process repeats countless times. And, all I pay attention to is really the inside of the car.
  • l943973l943973 Posts: 197
    The IBM voice software is great even for current 04 TL and 04 MDX owners since these models already suppose voice commands. They can just upgrade their DVDs in the future and get the new IBM voice software. My only concern is that the upgrade will probably be more expensive to cover IBM license issues.

       Are you a tuner or some sort? You know quite a bit about car design.
       Any good book to learn more about car design?

    Thank you very much,
  • robertsmxrobertsmx Posts: 5,525
    Thanks. But no. Its been a decade since I dealt with anything mechanical at engineering level.

    I've learnt much of the things by observation and participating in these forums though. I'm sure you have and will, as well.
  • I think it is pretty much the same except for one difference that I know of. The JDM version will have a new sensor that detects pedestrians since in japan some 30% of accidents occur with pedestrians. I don't think this feature will make into our RL.
