    but also, those systems add weight, which would account for the mpg differential with the FWD models. So that could possibly be the reason for different ratings.

    Well, permanent AWD systems (in that class of vehicle) do appear to weigh between 50-100 lbs more than the reactive systems. But I believe the EPA has a weigh allowance built into their calculations which would put the system vs system difference within the margin of error.

     

    It's definitely not a perfect science. But the fact that I found similar results with each and every model I was able to check is kinda telling.

    varmint:

    It was 2001 Civic HB that got high marks from Euro NCAP in terms of pedestrian safety and became the best ever to achieve 3/5 rating. Here is a link to NCAP’s Official Press Release on the same.

     

    It would be interesting to note that Honda has been slowly but surely pushing pedestrian safety in its US market PR (began with the new Odyssey).

    Using DI could help improve a little more, but 1000 lb and poorer aerodynamics and greater power train loss is still going to account for a few mpg off. As far as EPA rating is concerned, click here to go to a webpage trying to justify real world to rating discrepancy. Here is the excerpt of interest:

     

    “No laboratory test can simulate all driving conditions and driving styles. Trip length, traffic conditions, terrain, temperature, and weather all affect fuel economy. In addition, fast acceleration and heavy braking, driving at high speeds, carrying extra weight, using cargo racks, using electrical accessories, and using 4-wheel drive reduce fuel economy.”

     

    An inference to be derived is that if 4-wheel drive were already “tested”, it shouldn’t result in poorer fuel economy.

     

    As for permanent versus full time AWD systems, weight difference is primarily due to how they are designed / engineered. Honda’s VTM-4 is a full time AWD system but SH-AWD is a permanent AWD system, and the latter is said to have been derived off the former. Being electro-mechanical systems, however, they are lighter than most other hydraulics/all-mechanical systems.
  • varmintvarmint Member Posts: 6,326
    I stand corrected on the crash tests. Thanks.

     

    I wonder if they mean using four-wheel drive, as in, engaging the shift level below the dash. Not so much AWD, but the old-fashion lock the hubs kind of thing. It would make sense if they tested selectable 4WD vehicles in 2WD mode only, rather than both modes.
  • robertsmxrobertsmx Member Posts: 5,525
    With 4WD (manual), if they were testing for fuel economy, I would expect them to keep it engaged. In case of automatic versions, it would be impossible to have controlled scenarios.

     

    In case of SH-AWD (a permanent system), this may not be an issue since all wheels are powered at all times. In case of VTM-4, however, all wheels are powered during startups/acceleration but not during cruising. And in both cases, amount of power transfer varies dynamically.

     

    These variances only add to already complex set of scenarios that EPA is using to derive fuel economy estimates. So, they may be simply chopping off a percentage from whatever is achieved. In most cases, after all, the estimates are left to the automaker. EPA tests only a fraction of all vehicles (and only to confirm the claims).

    The bed line is a bit odd, it's taller at the front then it is at the back. Even more strange, the tail gate is lower than the bed line where it meets up.

     

    To be honest I don't even recall if the ones on the floor were leather right now. I took 288 pics and must've caught that, though:

    New Avalon is in there, also. Nicely improved over the old one. Bigger engine, too.

     

    Acura RDX looked pretty sharp. I'd like to see Honda/Acura challenge the Vue Redline, Forester XT, and BMW X3 in terms of small and sporty SUV, emphasis on sport.

     

    RDX has SH-AWD I believe, and a V6. Though I read it will not be based on the CR-V as was rumored earlier.

     

    In fact it looks much smaller than the CR-V in person, so I believe it.

  • varmintvarmint Member Posts: 6,326
    The RDX is based on a new platform. At least, new to the NA market. Everybody pretty much expects that the 2007 CR-V will be based on the same platform. So, which is based on which is an exercise in semantics.
  • carlisimocarlisimo Member Posts: 1,280
    Woah! Mugen (Honda-specific racing/tuning company) showed off an Acura RL concept at the Tokyo Auto Salon - the Legend Max.

     

    It's powered by Mugen's Le Mans engine: 4.0L V8, 500+ps in street mode (590hp in its racing application). It's longitudinally placed so it can't use SH-AWD; it's RWD with a manual transmission.

     

    Here's the link; if it's illegal hopefully the rest of this post can stay?

    I don't expect this concept to get anywhere, but I think it's writing on the wall for an eventual Honda V8.
  • anythngbutgmanythngbutgm Member Posts: 4,277
    That thing is downright mean... 590hp through a manual tranny to the rear wheels. WOW.
  • ateixeiraateixeira Member Posts: 72,587
    CR-V might get a longer wheelbase, then. RDX did seem smaller.

     

    I still liked it. Thumbs up.

  • varmintvarmint Member Posts: 6,326
    According to Acura, the RDX concept is 7 inches shorter than an MDX, which means the RDX is 181 inches long. The current CR-V is also 181" including the spare. Actually, the SE model is 181.8" apparently because of the hard spare cover! Anyway... I digress... the RDX isn't any shorter in terms of overall length. I do suspect that it is "shorter" in terms of height, though. Looked to have a lower roof line than the CR-V.

     

    Of course, that might just be a visual thing. There are a few styling elements that make the CR-V appear taller than it really is. Stuff like the integrated roof rails and vertical taillights bring the eye upward. The 19" rims and curved roofline on the RDX might counter that perceived height.
  • robertsmxrobertsmx Member Posts: 5,525
    MDX is slightly smaller and sportier than Pilot. I wouldn't be surprised if AHM carries the same formula for RDX/CR-V duo.
  • varmintvarmint Member Posts: 6,326
    Agreed. That's pretty much what I'm expecting.
  • ateixeiraateixeira Member Posts: 72,587
    Up close it didn't seem nearly as tall as the CR-V, maybe that's why it seemed smaller.

     

    I'll dig up the pics I took...here's the album:

    Photos relevant to this thread:

     

    50 - Ridgeline's door handle. Interior differs from Pilot substantially. Built for durability vs. appearance or feel.

     

    51 - Ridgeline back seat folks up, but that leaves a track so the floor is not flat.

     

    54 - Ridgeline interior shot

     

    57 - RD-X concept. Maybe that thick D-pillar makes it seem shorter than it is. No door handles! I think they use a camera in place of a side view mirror.

     

    Exhaust is integrated. Lights are LEDs. Overall look is sporty and aggressive.

     

    58 - Ridgeline door swung open

     

    59 - Ridgeline spare and storage well (HUGE!)

     

    61 - front of RD-X looks nice but not as successfully styled as the rear IMO. Front has hints of BMW X3 in the lights.

     

    Check out the glass sky roof also.

     

    62 - Ridgeline tail gate does not meet up with the sides for some reason. A bit odd.

     

    65 - Ridgeline rear seat. Middle position is too stiff for any long distances.

     

    66 - Ridgeline bed extended

     

    That's all I got.

    Thanks for the pics.

     

    The interior is another area when I'm under-whelmed. In this case I think the Tribeca is far better (different market segment, of course). I don't blame Honda for going with a traditional truckish design, but I would have thought they could give it something unique. Aside from the fold-up rear seats, there is little of that Honda magic in there.
  • ateixeiraateixeira Member Posts: 72,587
    Hey maybe we could get Honda and Subaru to team up, let Subaru do the interior and Honda do the exterior...LOL.

     

    It's not so much the styling of the Ridgeline, which seems kinda tacked on, accessorized rather than designed.

     

    It's the design and utility of the bed. Impressive. The thing has crowds of people ogling it. You had to get in line to check it out up close.

     

    Funny thing is the crowds congregated behind it, there were no lines to get inside.

     

    I think they designed the Ridgeline interior to handle mud and dust, probably hands with gloves, so plastics are kind of hard, but that's OK for a pickup.

     

    I just like how they beefed up the payload and towing.

     

    This thing will easily meet sales forecasts, watch.

    but I kind of like the front of the Subaru Tribeca. Pays homage to older subarus and is unique in todays market (at least to me it stands out). For some reason I like it. The porsche cayenne-esqe head lights could be different, but I really like the grill area on the tribeca. At least it is interesting.
  • ateixeiraateixeira Member Posts: 72,587
    You're not the only one, a handful of us like it, in fact all three Edmunds regulars that have seen it in person liked it better after they saw it.

     

    I'd prefer less chrome in the grille, but add a mesh grille in the front, and see the full design in person, and it's nice. Especially the interior, which makes the MDX look dated.

     

    MDX is due for an update, and the Tribeca interior sorta looks like the TSX', only applied to an SUV.

     

    Still, copy or no, give them credit for aiming ahead of the MDX, at the next generation, instead of the current one.

     

    Check the Tribeca thread, a while back someone put links to the interior of the MDX, RX330, and Tribeca, and the Subaru is easily the best design.

    the gauges look like a Matrix. The exterior is fugly. Looks kinda like a cockroach, but the rear looks like some car from the late 50s/early 60s (maybe a Stude' wagon? A lark?) Anyway, I know that I've seen those lights someplace.

    Subie quirk - that is the first good shot of the interior I have seen. Trust Subie to be different. That interior belongs in the Men In Black's cruiser. Which is not to say it isn't stylish.

     

    In the world of premium-branded cars, of course, I would think that the more conservative the interior the better (and the more upscale materials the better). Having been in the Toyota and Honda, I would have to rate the interior of the Pilot higher then the Tribeca, and the Toyota Highlander lower, but of course, the HL gets to be all-new later this year.

     

    Haven't been in the RX330, but IMO it looks a little too much "boombox" for a car of this class.

     

    As far as exteriors, the car world is beginning to converge too much. The Tribeca has many obvious overtones of the Nissan Murano/Infiniti FX in it. Have you seen the new M45? To me it looks just like the new RL from many angles. Even the lights are similar.

    Pilot is going to be redesigned this year (official announcement was made at NAIAS). But no word on MDX yet. I assume it will be as well since it is in its fifth year of the model run (launched as a 2001 model). But sales have been up so who knows?
  • varmintvarmint Member Posts: 6,326
    The Pilot is too conservative. The MDX is nice, just dated. It's due for an FMC this year and Acura's latest interiors have been impressive. The RX330 is ruined by those two metallic accents on either side of the center stack. But having sat in one, I can confirm that the materials are top notch, the gauges look great, and the controls are well placed. From a styling perspective, I like the Tribeca's dash. Too much faux metal trim for my tastes, but otherwise the design is pretty good. Some comments from the press refer to penny-pinching, though.
  • varmintvarmint Member Posts: 6,326
    I read that the Pilot was getting VCM. I haven't read anything about a redesign. It's due for a mid-life update, but not a full model change.

     

    The MDX is due for an FMC and prototype spy photos have been posted. I expect they will keep sales of the current model strong by not releasing information until the last minute. I'm anticipating that the MDX will get an upgrade like the Ody. Not a radical change, just more of the same basic goodness.
  • robertsmxrobertsmx Member Posts: 5,525
    I stand corrected. Pilot will be receiving MMC after all. From hondanews:

     

    “In the area of environmental leadership, Mr. Fukui announced plans to further advance and expand the use of Honda fuel-efficient technologies including its hybrid technology and Variable Cylinder Management (VCM) system. VCM will be applied to the 2006 Honda Pilot sport-utility vehicle scheduled to debut this fall.”
  • ateixeiraateixeira Member Posts: 72,587
    MDX has good ergonomics, but you can just tell it was designed in the previous decade. That's fine, it probably was. But I bet the new looks a lot more like the Tribeca's.

     

    Pilot's is sort of blocky, nothing wrong with it but there's no design flair at all. I'll agree with varmint (is that OK? LOL) and say it's just too conservative.

     

    Lexus has the right idea but it doesn't flow that well. The sides look tacked on. Boomboxy, sure.

     

    VCM is brilliant, I bet they get Pilot up to class-leading mpg.

     

    Has the new Ody with VCM had any teething issues? I'm bummed that you have to go all the way up to an EX with leather to get it.

     

    Street prices around here are $28k, it doesn't make sense to spend that much more than a basic Sienna/Ody ($22-25k) to save a few bucks on gas.

  • varmintvarmint Member Posts: 6,326
    Dang. I was hoping Robert might be right.

     

    VCM is good for about a 5% boost in fuel economy for the city driving cycle. On the highway, it has a greater impact (about 12 or 13%). So, I'm expecting about 18/24mpg for the VCM-equipped Pilot.

     

    Not sure that will be class-leading for long. But it is pretty good for such a large vehicle.
  • stickguystickguy Member Posts: 53,357
    the Ody feedback is that mileage is disappointing, even with VCM. Not that the mileage is bad for 4,500#, 255hp box on wheels. Just not close to whats on the sticker.

     

    Almost seems that VCM is great for the EPA test, but has much less impact to real world driving.

     

    20-28 is pretty darned high target for a big beast like an Ody. Same will likely happen with the pilot.

    Compared to EPA only, or compared to non-VCM models?
  • nippononlynippononly Member Posts: 12,555
    have to train themselves to drive like the EPA test, that is, not on and off the gas allthe time but making some small effort to maintain a constant speed. That is the time when the VCM will boost their mileage the most.

    I always find Honda enginess don't really "break-in" until about 15 - 20,000 miles. With the VCM technology new to the Ody, maybe 05 owners haven't reached that point? My milage on my 02 Accord has been consistant 32 mpg for this time of year, while the first winter with it I wasn't over 27 mpg...
  • stickguystickguy Member Posts: 53,357
    there doesn't seem to be too much difference between VCM and non VCM, though to be fair, the majority of us owners (here and on the Ody specific forum) have EX-L and touring models, so I can't really say about non-VCM.

    I agree with anythngbutgm - it has been my experience that it takes Honda engines a while to "break in."
  • robertsmxrobertsmx Member Posts: 5,525
    Based on my experience with three Hondas (currently own 1998 Accord EX with 112K miles, and 2000 Civic EX with 58K miles), 7-8K miles is a typical. The engine, the transmission and the fuel economy tend to settle down by then.
  • ateixeiraateixeira Member Posts: 72,587
    18/24 is fine given the size of the Pilot, i.e. bigger than most competitors.

     

    So the jury's still deliberating on VCM? I can afford to wait and see neeways.

     

    Maybe later on Honda will put it on the Ody LX.

    I drive it like a bat out of hell on the highway. I'm "that idiot" in the minivan doing 90 mph. But I still get 23 mpg. That's why I think it's BS when people say you should slow down to save gas. When they stop selling those gas guzzling Hummers and other trucks that can't break mid-teen mpg's, I'll do my part.

     

    I think 23 mpg with a full load of family and gear with the A/C running and Finding Nemo in the DVD player is doing pretty durn good when you average above 75 mph over 600 miles including stops.
  • varmintvarmint Member Posts: 6,326
    VCM is more than just the hardware in the valve system. It also requires ANC (active noise cancellation). They have to study the harmonics of the engine compartment and probably a dozen other factors in order to get the counter frequencies correct.

     

    It's going to take a little time.

    Maybe they are hedging their bets with VCM, making sure it's reliable first. I think that's the first application on the 3.5l V6.

     

    I think VCM just won't kick in if you drive like that!

    VCM was used in Japan for about a year before they brought it over here (in a 3.0L engine). I suspect that gave Honda their beta testing data.
  • robertsmxrobertsmx Member Posts: 5,525
    Yep, VCM with the J-series V6 has been sold in Japan since June 2003 in Honda Inspire.
  • varmintvarmint Member Posts: 6,326
    It's not like the technology is all that new anyway. As far as the valves are concerned, it's just a matter of getting them to close under certain conditions, rather than opening wider or longer like they've done in the past. As I mentioned earlier, it's the ANC that requires development and attention.
  • ateixeiraateixeira Member Posts: 72,587
    That must be a complex camshaft, to vary timing, lift and even whether it lifts the valve at all!

     

    VCM has been around for a while, but I'd still wait and see how it works on this particular engine.

     

    I'm interested, though.

  • robertsmxrobertsmx Member Posts: 5,525
    Not really complicated. It is VTEC at work. In fact, Honda has used this concept of controlling opening/closing of valves using VTEC for years now. In the most basic form, the idea was to keep some valves shut at low engine speeds to create a swirl (speeding up the intake charge).

     

    This idea was also used in the first motorcycle application of VTEC (2002 Interceptor). In that case, the 800 cc 90-degree V-4 DOHC VTEC engine operates in 2-valves/cylinder mode thru 7000 rpm and then switches over to 4-valve per cylinder mode from there on to about 14K rpm redline.

     

    With VCM, the VTEC now applies the logic to shut down all valves (instead of two) in one bank of the Vee. In Cylinder Idling System (in Civic Hybrid), the VTEC is designed to just that but to shut down three of four cylinders during deceleration/braking.

    Well, you don't HAVE to have active noise cancellation to have a VCM type sytem. And you don't need to "study" the engine harmonics to have noise cancellation eitheer. You just need a simple chip that will calculate the inverse frequencies on the fly. Just integrate a mic somewhere in the cabin to use as your source, and you're done. If you do it that way, you'll even cancel out road noise from your tires, etc.
  • robertsmxrobertsmx Member Posts: 5,525
    Thats exactly how Honda's ANC works (used in Odyssey w/VCM, Accord Hybrid which has VCM and Acura RL which doesn't have VCM at the moment). It is a two mic system that takes a range of input frequencies and inverts them to neutralize their impact.
  • ateixeiraateixeira Member Posts: 72,587
    Wow, so the camshafts are asymmetrical, then. No wonder they need active noise cancellation.

    When running in 3-cylinder mode, the configuration is really that of an I-3 (as far number of cylinders being fired are concerned) although all six pistons are still moving. But, I don't know if firing order of a typical I-3 (as in Insight) would be similar to the three cylinders in this V6 system.
