    similar situation here: No pulling, about 4000 miles, wishing for a bit more boost in the parking lots... and still enjoying my MDX! :shades:
  • Thanks, everyone, that is good to know. I notice that the material on the MDX describes the steering as being variable torque (or something like that). Does anyone know if that means it's potentially adjustable, eg, could the dealer adjust for more boost?
  • I test drove a 2007 MDX with the 19" wheels and it rode quite rough and pulled to the right. I purchased an MDX with the standard wheels and it rides smoothly and no pull in either direction. Gas mileage registered 20.4 on the 100 mile trip from dealer to home. It has now settled to about 18MPG here in the Orlando, FL area. Am very pleased with the car.

    Speed sensitive power steering adjusts boost depending on speed. I don't think your dealer can adjust the boost.
  • varmintvarmint Posts: 6,326
    With the MDX, the steering is actually torque-sensing rather than speed-sensing. Torque-sensing works off of the engine rpm, rather than the vehicle speed.

    End result is more or less the same. And I agree that a dealer isn't likely to mess with it.
  • robertsmxrobertsmx Posts: 5,525
    I thought torque-sensing was more of a function of the DBW system, as opposed to power steering system itself.
  • varmintvarmint Posts: 6,326
    Not quite sure what you meant when you wrote, "a function of the DBW system". Are you suggesting the term torque-sensing steering refers to manipulating the throttle rather than the steering? That would be incorrect.

    In don't have a link handy, so read up on the 2nd gen TL and TL-S. The base model used a speed-sensing design, while the Type S got torque-sensing. With a little digging, you may find a better explanation of the difference between the two designs.
  • I agree with you about the tires. I have the base model MDX with the Goodyear tires on it. The steering at highway speed is horrible and a ton of work not to mention a rough ride all the time. I just had a dealer loaner for 2 days that was loaded with the Michelin tires on it. What a difference! Great steering and a much smoother ride. I can't beleive that Acura put the Goodyear tires on their cars to save $25 per tire. AMAZING TO SAY THE LEAST!

    I tried finding out information on torque-sensing part of variable assist steering but most of the returns were related to patents. TL (including base) apparently has torque-sensing variable assist steering as does MDX. But no details on how it helps. RL uses speed sensing variable assist system.

    Regardless, it is highly unlikely that people looking to reduce assist at lower speeds will get any help at dealerships. It’s a part of the design (greater assist at lower speeds, and reduced assist at high speeds).
  • varmintvarmint Posts: 6,326
    Yes, the current TL and TL-S both use torque-sensing. It was the second generation of the TL that used speed-sensing on the base models. In 2002, the TL-S got torque-sensing, while the base remained speed-sensing.

    Unfortunately, Acura's media site doesn't provide much detail. This is all that has to say on the subject.

    The 3.2 TL features a speed-sensitive, variable power assist system designed to complement the model's handling characteristics.

    By varying the amount of power assist according to vehicle speed, the system provides light steering effort during low-speed parking maneuvers and, as vehicle speed builds, progressively heavier steering effort for a positive and secure feel.

    The TL Type-S is equipped with an exclusive sport-tuned, power steering system (similar to the CL Type-S). The Type-S uses a torque-sensing rotary valve steering gear that varies the amount of assist according to steering input and the resultant torque generated between the pavement and tire. The system also varies assist based on engine speed, helping make steering light in parking maneuvers and heavier as speed increases for enhanced road feel.


    Might be a good question for Shawn.

    Because I want to know the difference in light offroading without the Differential Lock button that the old model had. Is the new one as adaptable like the old one?
  • robertsmxrobertsmx Posts: 5,525
    With VTM-4 as in the old model, lock button was to engage all wheels upto 18 mph. With SH-AWD, the button is unnecessary since all wheels are engaged at all times anyway.
  • Have an '04 and '07 and the former is much better w/ "light offroading" and in deep snow ( just got two feet of it) The '04 will go anywhere I need to go, not so sure about the '07. That being said, the '07 is light years ahead of the previous gen. in everything else.
  • varmintvarmint Posts: 6,326
    Ditto that. At least in theory.

    The "lock" feature available with VTM4 not only locked the torque output 50/50 fore and aft, it also locked the rear axle half-shafts in a 50/50 spread. While this is something you would never want to happen on dry pavement, it does give the vehicle an advantage on slick or loose surfaces.

    On old-school "four-by-fours", they would add devices known as lockers for the same reason. Here's an example of an air-powered locker.

    SH-AWD can send power left and right between the rear axles, but I've read nothing which suggests the system is programmed to lock the rear half-shafts when one side slips. It is far more likely the VSA system will instead clamp on a slipping wheel using the brakes. That action send power back across the differential to the wheel on the other side. If that other wheel starts slipping, VSA will reduce power from the engine.

    This combination of SH-AWD and VSA is very effective when the vehicle in on the road and has some momentum. It'll help keep you from hitting the guardrail. But at low speeds when climbing over rocks and such, it's just a likely to get you stuck.
  • Looking for what monthly lease payment might be for dealers in Long Island area?? Any input appreciated.
    Paying taxes, tag, bank fee up front. -TC
  • For Your lease your looking at about $650 - $700 per month for a 36 month, 0 down, 15K miles per year.
  • Can anyone who has an 07 with the DVD entertainment system? Or anyone who knows how it works? let me know the following:

    1. how many people can access different types of entertainment at one time, eg, is it two people in the back plus the front seat occupants?

    2. can a front seat occupant use the headphones to listen to music either from a CD/DVD or radio (terrestrial or XM)?

    3. will the system play home produced DVD's, eg, TV programs captured and burned?

    Many thanks.

    Hi everyone. I'm in the market for a new car for my fiance and we've narrowed it down to two cars of which the new Acura MDX is one. We drove one with the tech pkg but we're also interested in the sport pkg. Does anyone have any feedback for me on it? The one we drove seemed very nice.
  • my3rdrxmy3rdrx Posts: 167
    Personally I much prefer the Sport over the plain Tech package ~ the improved handling in Sport mode and perforated leather-trimmed seats are well worth the addtional cost.
  • mdjaymdjay Posts: 3
    Hi all,

    Is the 2007 MDX base suspension exactly the same as the Comfort mode in the sport model? Or is it somewhere between Comport and Sport mode?

    Thanks

    Just beware...this SUV EATS GAS!
  • mdjaymdjay Posts: 3
    Hi all,
    we've trying to see if other than being perforated, is there any other difference between leather in the sport package vs. non-sport. We keep seeing that the sport has "premium full-grain" leather. Does non-sport have a different grade leather?

    Thanks
  • varmintvarmint Posts: 6,326
    The base model suspension is somewhere between the Sport and Comfort settings on the Sport model. Everyone's opinion will vary, but most reviewers report that it's a fairly good compromise between the two.
  • varmintvarmint Posts: 6,326
    Yes, they have different grades of leather. Best to stop at a dealer and see for yourself before making a decision on that issue.
  • lucien4lucien4 Posts: 68
    I didn't go for the sport since my concern is that the leather just collects dirt. Also the base suspension is already quite tight so this is not for everyone.

    And yes, best to see for yourself and test drive both.
    Regarding gas consumption. It's normal for this size of SUV.
    I do get the rated EPA numbers.
  • Over 5000 miles on my 2007 MDX.
    Never reset the "B" odo --> 18.5 mpg.

    Was driving our '07 last week after an ice storm. Trying to leave our neighborhood, basically WOULD NOT move due to all the systems involved in trying to prevent wheel spin, etc. Was actually pretty funny to watch.

    This may help some people save some "green". My complimentary XM subscription ran out last week and I had heard a while ago that there was a promotion called "winback" which you could mention when you go to renew it and you would be charged $77 a year. It is still in effect as I just renewed today. There are other posts which outline the exact procedure to follow so I won't repeat them (search all posts for xm radio promotion). Has anyone found a better deal on xm service?

    Next time turn off the VSA. It really can hinder launching in slick conditions. Just make sure you re-engage after you get moving.

    Not a whole lot about snow performance (other than one or two favorable remarks), but here's an article about SH-AWD on a track covered with ice and a few inches of snow for good measure. Props to Chas2 for finding it.

    We had only 1" of snow and it performed without problems on that (no slipping, perfect traction).
    Didn't have a chance to try on tougher conditions but typically you want to have appropiate snow/traction tires in these conditions anyway (regardless of AWD).

    Also turning off VSA can help a lot if it keeps blocking the tires and you don't gain any speed. Once you're moving it's safer to turn it on again.

    You can see some sample fuel economy on truedelta.com. I do get the EPA numbers (16-17 in town, 21-24mpg on highway).
