    ..."So is there more potential profit for an auto maker in going the hybrid route rather than the diesel route? Since these big manufacturers are looking 5-10 years out at a minimum I'd have thought that there would be more by now. Except for Honda, which has trapped itself with it's hybrid technology and VW of course, there is almost no mention of diesel autos for the NA market in the press. "...

    I am not sure what you mean by Honda trapping itself with its hybrid technology?

    My own take is Honda has used its Civic platform for such concepts as: gasser, gasser hybrid, nat gas, hydrogen, and lastly diesel (in Europe)I think it does not demo E85 simply for it would have to upgrade fuel delivery systems due to the highly corrosive nature of ethanol on aluminum, etc.

    Not only does the platform continue to be HUGELY successful, it has defined the segment of ECONOMY cars. It has helped to pioneer the mpg standards within that segment and has demonstrated in the real world the a fore mentioned fuel options. I probably left out a lot of other accolades.

    As for the % of increase of diesels, we need only use the growth of the SUV segment as a model. It started off at something like 1% of the population and in 30 years rose to a 12% population. This was hailed on the one hand, as the invasion of the mongol hordes, breeding multiplying uncontrollably and taking over the world ending western civilization, as we know of it. On the other hand, 11% growth over 30 years is LESS than half of 1 per cent per year. .00367. So disingenuous to try like hell to keep diesel out and when it is shown to be impossible for a myriad of reasons to keep it out, vilify diesel for lack of so called "robust growth".

    For as much hot air as we devote to the "GREENING" of the environment, cutting back imported oil, yada, yada, the small car segment is less than 25% of the passenger vehicle fleet.

    I would say that given that reality trying to shoe horn folks into that segment would be a bit like trying to fit cinderellas glass slipper onto the feet of the wicked sisters. So for sure lets recognize fairy tales and put diesel on the SUV and pick up truck,luxury car markets for the 25-40% better fuel mileage. Its worked for big rigs for literally generations.

    The IMA as it was and is currently designed is not capbable enough for midsized vehicles. It is very good for smaller vehicles like the Civic and the just announced smaller vehicle to be built probably in Indiana. The Insight is and was a concept and the HAH was just wrong. Honda needs to be in diesels in the midsized segment ( Accord, Ody, Pilot, MDX, etc ).

    I'm not trying to push any agenda one way or the other. As I've said before I'd jump at a chance to use biodiesel and especially a hybrid-diesel that can use bio diesel.

    My question though is, 'Are we not likely to see many diesel autos here due to the expense of manufacturing them?' Outside of VW and Honda are all the others shying away from diesel autos for NA? Ford and Toyota seem to be saying so. GM? Nissan? Hyundai?
  • ruking1ruking1 Member Posts: 19,826
    I think a good question. Again my SWAG, given the economic health of and declining market share's of the big three, this is probably NOT an opportune time to get into this segment (diesels). I think if it has the profit potential of the suv/P/U truck segments they would integrate/switch. They already have steady year to year diesel historical data in their 2/3 series trucks. So all they need is a 1 series killer application diesel engine/s. Ford for example has announced a F-150 diesel option.

    I have also read in passing, that in some truck plants in the USA, diesel engines are ALREADY being OEM'd or assembled in the USA. They obviously have been for "EXPORT" if I am using the correct terminology.
  • ruking1ruking1 Member Posts: 19,826
    Just heard this in passing on "Motorweek" as they reviewed the new 2007 Toyota Tundra. The host mentioned that some time in the future, there will be a diesel Toyota Tundra model. My SWAG would be 2007.5 or even 2008.
  • jeffhempeljeffhempel Member Posts: 3
    Does anyone know of a high MPG diesel vehicle available in the USA? Any coming this way in the future. Europe has all kinds of high milage diesels in both cars and pickups. Why not USA?
  • eliaselias Member Posts: 2,209
    jeff, mylocal VW dealer has a bunch of new 2006 jetta TDIs on the lot. mid-$20k range. you might find a leftover 2006 new beetle TDI too, $20k for one of those. your local VW dealer ought to be able to find you one if they don't have one on their lot.
    but if you are in one of the five CARB state you are out of luck unless you find a used one with at least 7500 miles.
    as for the future 2008+ diesels, there are lots of pre-announcements but i recommend skepticism.
  • ruking1ruking1 Member Posts: 19,826
    ..."I'm not trying to push any agenda one way or the other. As I've said before I'd jump at a chance to use biodiesel and especially a hybrid-diesel that can use bio diesel."...

    It will be interesting to see how the problem/s is/are solved. Even with the gasser hybrids, the oem has yet to come out to say there is an app 20% savings for the hybrid portion. A side issue is 20-30% hybrid will be knocked off the stated mpg of 60/50 for the 2008 model year. The real world for example is instructive. My gasser only gets 38-42. Under like conditions I would SWAG the Prius would indeed do 48 mpg (my TDI does 48-52) So the real world advantage for gasser hybrid over gasser only is 48-40=8/48= 16.7%

    Irregardless, part of the problem is you have a dual system for having very high torque at low RPMs and operating speeds. So where you would (in theory) reap up to 20%% advantage with a higher reving (atkinson cycle)engine, whose low torque high revs disadvantages are off set with a high tech high torque LOW RPM electric motor, in diesels, I am swagging not more than 10%. This of course is probably not cost and operationally effective. Indeed much has been written about the fact the extra hybrid cost is really not recoverable on an operational level. Even less so for the RANGE of 4500 to 7,500 premium paid. This is not to mention the cinderella cinderfella aspect of cost of replacement battery issues at 6/8 year mark. On the diesel comparison between the gasser/diesel a 500-1000 dollar difference puts B/E at 2 years and or 30,000 miles and in some cases above. Also all this to specific points are/is not very sound bite able.

    I would agree that one more option to use alternative fuel: such as bio diesel, is a plus.
  • jeffhempeljeffhempel Member Posts: 3
    elias, thank you for your input, however, I have a small business and need at a minimum a compact pickup. I love the VW TDI's and should own one for my personal use, but I drive my work truck 35,000 miles per year. I checked out European trucks with diesels and they get up to 56 mpg! I cannot import them to USA because of "emission requirements". I cannot believe the Big Three are sooo shortsighted.
  • kdhspyderkdhspyder Member Posts: 7,160
    I agree. I don't understand the lack of diesel engines in small pickups since these are the most common types in other parts of the world. I know why the trucks cannot be imported, there is a 25% special import penalty on trucks. Thank you Big Three! But why the detroiters haven't been building diesel pickups here is what I don't understand.
  • ruking1ruking1 Member Posts: 19,826
    I have said this about diesels in other threads. The diesel with its 500-1000 dollar premium over like gassers make economic sense starting approximately at 20,000 miles per year. B/E occurs usually at the 1-2 year point. So with 35,000 miles per year as a yearly metric, SAVINGS happen very very quickly. Small business miles seem to be of the rugged type, again that is also a forte of the diesel engine.

    Again this is pretty transparent to compare.

    (Toyota Tacoma 4 cyl)

    2.45 UR
    2.69 ULSD
    35,000 miles

    26/27/56 mpg. = 1,346 gals/1,296 gals/625 gals diesel.

    This would equal $3298/$3176/$1681.

    MPG savings are 54/52 %
    $ savings are 49%/47%.
  • winter2winter2 Member Posts: 1,801
    Have you ever considered the Dodge Sprinter? It is a rebadged Mercedes diesel van.

    I would like to see more trucks (small to medium) with diesels. If Dodge had put a small diesel in a Dakota, one would be sitting in my driveway right know.

    I own a Jeep Liberty Limited CRD and it has been pretty good. It is fuel efficient and yet powerful. It has been quite reliable too (have only 16K miles on it though).

    Give it another model year or two and we will be seeing more diesels. As to the big three, do not count Daimler-Chrysler amongst them. They have lots of diesel powered stuff waiting to get into the U.S.
  • ruking1ruking1 Member Posts: 19,826
    ..."As to the big three, do not count Daimler-Chrysler amongst them. They have lots of diesel powered stuff waiting to get into the U.S."...

    Yes, it is looking like the only domestic oem to bring a new dieselproduct offering on the market will be Ford in the F-150 model. I read they took a serious hit to their most profitable, meat and potatoes segment. So a diesel F150 would make sense as ANY increase in sales would help. While I would think a diesel motor in the Tahoe series SUV would be the ultimate killer app with targets of 24-30 mpg, the fact of the matter is they are doing REAL well without a diesel offering. Again I am swagging they would see a diesel offering as canabalizing already stellar sales for that series model (GM/Cheverolet/ etc)
  • hwyhobohwyhobo Member Posts: 265

    Yep. That's what Detroit seems to lack today - foresight. They seem hell-bent on waiting until the bottom falls out of the market segment, and then attempt to catch up. Of course, in the meantime they lose 3-4 years out of the cycle, creating an opening for someone else to eat their lunch. They got lucky with Honda and Toyota having invested in SUVs and trying to milk that market, too, but that may not last.

    While I would think a diesel motor in the Tahoe series SUV would be the ultimate killer app with targets of 24-30 mpg

    Agreed, that and a minivan with 35/45 mpg. I think the latter is quite achievable with modern diesel technology as long as Detroit doesn't go stupid with the power trip and the "we've got a bigger engine than the competition", as if that was the most important thing these days. Unfortunately, Detroit just seems incapable of getting their heads out of past decades.
  • eliaselias Member Posts: 2,209
    no minivan is going to get 35 or 45 mpg. too much weight, too much frontal area. it's just not physically possible. imho.
  • hwyhobohwyhobo Member Posts: 265
    How about 30/40, then? I think with a diesel similar to the the Merc 2.7l and a stick that should be possible, even with CARB-compliant mods.
  • kdhspyderkdhspyder Member Posts: 7,160
    The Odyssey is doue here in MY 2009 with a diesel option. If a gasser Ody gets say 22 on average it seems to make sense that a diesel would be in the 30-32 mpg range on average. 40 mpg would be a stretch but it's a good goal.
  • hwyhobohwyhobo Member Posts: 265
    I could live with that. Too bad Detroit is behind the curve again. I admit to being a bit of a stuck in the mud buy-American-if-you-can kinda guy, but the policies of the big three in recent years make me feel like they're pretty much flipping the customers off, and that offends me.
  • eliaselias Member Posts: 2,209
    well, hobo... consider that the liberty CRD can get barely 30 mpg in optimal not-too-fast highway driving. i don't think a minivan can do much better than that on highway due to similar weight & frontal area. i can think of one way that a diesel minivan can get 30 or more in suburban/around-town driving however - add a hybrid system to it. consider saturn vue hybrid - supposedly it gets about 30. swap its gas engine for diesel and poof, it gets 40. but both diesel engine & hybrid drive would add cost... some of us would gladly pay it though... i'd rather pay detroit/japan/australia/euro-land the extra $ than have it go into countries which allow terror funding.
  • jkinzeljkinzel Member Posts: 735
    While I would think a diesel motor in the Tahoe series SUV would be the ultimate killer app with targets of 24-30 mpg,

    I agree, however the Tahoe is a little big for us. We purchased a Ford Explorer new in 1993 and it’s still going strong. If Ford put a diesel in the explorer I might buy one again, however with their last announcement about no diesels in passenger cars, I guess I can kiss that dream good bye. Im assuming from reading the article that only pick-ups and bigger get the diesels.

    “Ford had considered diesel engines in cars such as the compact Focus. A diesel usually boosts fuel economy by about 30 percent. A European diesel-powered Focus gets about 50 mpg on the highway. But tougher U.S. emissions rules took effect this month. The rules make all diesel-powered vehicles sold in the United States more expensive because of added filters and other emissions equipment.”

    The above quoted statement seems bazaar at best if my facts are correct and please inform if I’m wrong, but: In another four or five years do not the European emissions standards and the US standards end up on a level playing field? If this is true and Ford wants to continue to sell cars in Europe, then do they not have to comply with these standards that should be the same in the US? This should apply to GM as well.

    So Ford is going to Kiss off the diesel in the US and lean towards hybrid and ethanol because the diesel will cost too much to meet emissions.

    A quick look at Ford web sight and one will notice that the Escape gasser is $6,000 cheaper than the Escape Hybrid. If you put $6,000 worth of filter on the Escape you would have no room to drive it.
  • hwyhobohwyhobo Member Posts: 265
    Sorry, I think Liberty cannot count as an indicator of what a diesel engine is capable of. 4WD SUVs have always had lousy mileage compared to other vehicles of the same mass. I also don't think the diesel in the Liberty is optimized for fuel efficiency.

    If you can get up to 30 mpg on a Sprinter with enormously larger frontal area and weight, I don't see why 40 should be such a challenge on a minivan. Perhaps lower the profile if need be, why not. I think it's achievable, and it would be a big selling point these days.

    BTW, I am not a huge fan of diesel in general, but I am tired of funding ME terrorists and pi$$ing money away that could be used to fuel our economy (or my retirement).
  • ruking1ruking1 Member Posts: 19,826
    To me I would also include the (diesel) Ford Explorer. As you probably know the Ford Excursion already has the diesel option.
  • berniedgberniedg Member Posts: 54
    I agree 40 mpg should be doable.
    Heres a 2.2l CRD Santa Fe --U.K market--, (for comparison) thats does 7.3l/100 km combined, or 39 MPIG average, sorry don't know U.S gallon conversion.
    Granted the Santa Fe is about 3800lbs, 400 lbs lighter than outgoing Dodge Caravan. Too bad American trucks/vans are getting fatter not lighter. Too bad. This is what we need in North America ! (F,GM, DCX) Are you listening, anyone home ?

    Bernie, if you want to convert liters per 100 km into US MPG, just divide the liters into 234.34, like so:

    mpg = 234.34 / l

    where l = liters per 100 km.

    It works the other way around as well, so:

    l = 234.34 / mpg

    I'm in full agreement here especially if the fuel can be created here like biodesel and is replenishable.

    This is a nifty little program for converting (hence the name) measurements of all kinds.
  • hwyhobohwyhobo Member Posts: 265
    Alas, it has a rather poorly designed interface, and it forces you to do many clicks instead of just one. It could be designed like a calculator with many buttons - enter the value and click a button. Oh, well, the curse of working in an engineering field. ;)

    I do have a script for converting things for me, but we're getting a bit off topic, I guess. :)
  • eliaselias Member Posts: 2,209
    hwyhobo, no need to apologize for disagreeing. you are in good company.
    i try to follow various sprinter newsgroups/etc, and i've never read of anyone getting more than 25 mpg in a sprinter.
    i test-drove the tiniest sprinter (cargo version) a couple years ago. it was nifty but the cacophony of highway-road-noise was a dealbreaker. perhaps the tiniest passenger version is not so bad with regard to road noise.
    i would definitely consider sprinter as a platform for a conversion-van, but i don't need one of those.
  • larsblarsb Member Posts: 8,204
    Um, guys, i HATE to break this to you, but:

    There is no oem Tacoma diesel or otherwise in the world which achieves 56 MPG on the USA mpg chart.

    Nice to fantasize about, but not a real vehicle. Sorry. :shades:
  • kdhspyderkdhspyder Member Posts: 7,160
    from London and Paris..

    Here is this gem too. Carbon emission cap to end vehicle production in Europe?

    Snippet:
    Gas-guzzling sports cars, 4WDs and people carriers could be priced off European roads within five years after a crackdown on carbon emissions.
  • ruking1ruking1 Member Posts: 19,826
    Hate to break it to you, but I was not referring to a Tacoma diesel. That 50's number was indeed hypothetic as there was not a specifically targeted or mentioned vehicle, as like when I specify usually an example; such as 2003 TDI, etc. And of course we always try to talk of USA conversion for we are in the USA. But you know all this. :)
  • eliaselias Member Posts: 2,209
    i think there might have been a few USA rabbit-pickup-diesels way back when. not sure. but if those beasties did exist, i bet they got ballpark 50 mpg.

    Mini Diesel

    quote-
    It'll be the first ever diesel Mini to wear the sporty Cooper badge, so it's no surprise that the Cooper D manages 62mph in 9.9 seconds and presses on to 120mph. But, despite being a fun hatch, it's also the cleanest (118g/kg CO2) and most economical (64.2mpg) diesel Mini ever.
    -end

    And it is not more expensive than a "petrol" Cooper. ;)
  • ruking1ruking1 Member Posts: 19,826
    As goofy as it sounds the Jetta TDI has ground clearance issues in real world driving. I would swag the Mini with even a LOWER center of gravity also has them. Despite that ( you can buy aluminum protector plates) that sounds like a WOO HOO to me!!! 192# ft of torque and 50 mpg!! Again would be a great product in the USA!
  • berniedgberniedg Member Posts: 54
    When you think about future fuel prices doubling and tripling from current prices, how would you design a smart diesel SUV for USA market ? For me.
    1/ reasonable acceleration: approx.10sec 0-60mph.
    2/ low weight under 4000lb vehicle and good drag number.
    3/ carry 5-6 people in comfort and tow 2k to 4k trailer.
    4/ nice style at a reasonable purchase price !
    5/ use a 2.2l CRD engine, approx 260lb/ft torque, able to propel 4000lb vehicle with ease and achieve 40mpg.
    Which car company will pull this off, first ?
    Probably Honda.

  • kdhspyderkdhspyder Member Posts: 7,160
    Honda has already announced for MY 2009
    a diesel Odyssey option
    a diesel MDX option ( prolly Pilot also )

    a probable diesel Accord option.
  • moparbadmoparbad Member Posts: 3,870
    Actually, the Accord is the only one that is confirmed for 2009, the 4 cyl diesel for the Accord is already completed and is undergoing testing, the V6 diesel for the Ridgeline, Odyssey, Pilot, MDX is only a rumor at this point.
  • hwyhobohwyhobo Member Posts: 265

    Sorry, I think Liberty cannot count as an indicator of what a diesel engine is capable of. 4WD SUVs have always had lousy mileage compared to other vehicles of the same mass. I also don't think the diesel in the Liberty is optimized for fuel efficiency.

    I would have to disagree with you about the Liberty. I own a Liberty CRD and get far better FE than many smaller SUVs. On a highway trip I can get greater than 30 MPG if I keep the speed under 65 MPH. Yes, it is not optimized for FE but if driven judiciously can achieve very good FE. Yes, it has the aerodynamics of a cinder block but no small SUV is really all that aerodynamic to begin with. My Liberty weighs 4306 pounds empty. Do you know of any vehicle that is that heavy that can achieve 30+ MPG?
  • winter2winter2 Member Posts: 1,801
    Comes out to about 32.5 MPG (U.S.).
  • winter2winter2 Member Posts: 1,801
    Funny you should bring up this article. There so few gassers that meet the 120 gm/km carbon emission standard but there are lots of diesels that do.

    Most of the gassers are under one liter in displacement.

    Here is the link:

    Then you disagree mainly with elias, not me. I have no dog in this hunt. I do not own a Liberty. I talked about a minivan, but elias used the example of a Liberty CRD to show why good FE gains are not likely.

    Anyway, I am glad you are getting good results with that engine. That's the name of the game - use your disposable income for something sensible instead of throwing it down the ME rattlerhole.

    Since you asked, YES I do. The Highlander Hybrid can do that at 5600+ pounds. :shades:

    My cubemate regularly get 30+ for his 4wd HiHy tanks.
  • qbrozenqbrozen Member Posts: 33,737
    The Highlander Hybrid can do that at 5600+ pounds.

    Actually, the highland hybrid is 4245 ... not that it makes your point any less valid, however. just wanted to straighten that spec out.

    '11 GMC Sierra 1500; '98 Alfa 156 2.0TS; '08 Maser QP; '67 Coronet R/T; '13 Fiat 500c; '20 S90 T6; '22 MB Sprinter 2500 4x4 diesel; '97 Suzuki R Wagon; '96 Opel Astra; '11 Mini Cooper S

  • larsblarsb Member Posts: 8,204
    Yep my bad - the HiHy does weigh 4245.

    So I guess I don't know a vehicle that weighs as much as the LibCRD that can do 30+ MPG..... :cry:

    none of my VW TDIs have had ground clearance problems so far:
    03 TDI variant 5 spd
    05 passat
    06 newbeetle DSG
    06 jetta 5-spd

    but then again, i tend to drive on PAVEMENT! HELLO! ;)

    also my basis for comparison for ground clearance has been about 25 years of driving Z28s and more recently an australian GTO. the Z28s especially had clearance problems in deep snow, but other people are smart enough to avoid driving Z28s in snow. me, i would slap some 245/50-16 eagle M+S tires on the back and have a blast countersteering. the goodyear dudes in california were fascinated with those tires after i drove the car there - they had never seen them before.
    i haven't tried the GTO in snow yet because i don't have proper snow tires for it, and the jetta TDI is a way better winter car than a GTO of course.
  • ruking1ruking1 Member Posts: 19,826
    I am talking about driving on THE PAVEMENT!! HELLO!! HELLO!!! Indeed as you probably know oem puts plastic. While you are probably not interested, there are steel aluminum front undercarriage protection products(oil pan protection. Some even sell springs that raise the car. You can see them on www.TDI.com.
