What about VW TDI engine?

Well, I'm considering purchasing a new Golf
(have to get _something_--two non-licensed,
non-insured morons just totalled my perfectly
good 1986 Mazda 323) and am very attracted by
the TDI engine. Anyone have any remarks on the
durability of this engine (according to theory,
should be significantly better than the gas
engine, but that's theory...), starting in cold
weather, real-world MPG, emissions, or anything

    I've got a TDI in my New Beetle. Get it! It's another brilliant piece of engine design from VW.

    Forget everything you've ever heard about diesels. It's quiet, clean (meets TLEV emissions standards for all 50 states WITHOUT additional controls), very peppy, and awesome pulling power. When I went to run some errands two saturday's ago, the thermometer read -4F. The glow plugs warmed after about 5 seconds, and the car purred on the first try. It's also torquey enough to start the Beetle moving from a dead stop in first gear without giving it gas!

    And it gets great mileage. We picked ours up on 16 December. On 11 Jan (ok, we were out of town for a week and left the bug, but still...) and almost five hundred miles later, we filled the gas tank for the first time. About 43 MPG in mixed highway and city driving. Plus, diesel in Connecticut is taxed at a different rate, so it's CHEAPER than regular. And as far as fuel availability goes, I can't speak for your area, but here, it's good. Of the seven gas stations reasonably close to our home and work, six have diesel. Ironically, only one of those actually advertises the fact on its sign, and all of the others only have it at one pump, but they do have it.

    And you're right. In theory, it should last a lot longer than a gas engine. My neighbor has a 1971 Mercedes diesel which (according to him, anyway) has never had any major engine work performed. Just belts, glow plugs, oil changes, etc.

    There are only two drawbacks that I know of: 1) after about a week, the underside of the back of your car (near the tail pipe) is covered with dark grime, which you can only see if you bend down, and which comes right off with a little soapy water; and 2) if you ever run out of gas, the check engine light comes on and stays on until you see your dealer.

    But don't take my word for it. Check out Motor Trend magazine's Import Car of the Year (New Beetle) article (Feb '99 issue), or look at the long term road test for the New Beetle here on the Edmunds website.

    Go for it! Happly Dieseling. Prrrrrrrrrrrrr.
  • I, too, purchased a Beetle TDI. Just got delivery 2 weeks ago. The engine is great. Living in Oregon there are lots of hills, mountain passes, etc, and I was concerned about comments that the car is underpowered. They're wrong. This car cruises over the steepest passes in 5th gear. It will accellerate in 5th uphill at 1500 rpm. I think this has to do with the abundance of torque. I think it's a bit slower to accellerate quickly from a dead stop (like a stoplight), but still plenty snappy. And the first trip got me a fraction over 50 mpg (really!). The second tank netted 47.5 mpg--with about 1/4 city miles. I've only been in town for the past 1 1/2 weeks and it seems the tank is emptying quicker, but it'll still take weeks before I need a fill-up so I don't know what the mileage will be. It's a great engine--- and it's something a little different. Good luck.

    For some great discussion and technical information on the TDI you must go to

    The site is FANTASTIC.

    Go for the TDI !!!!!

    Thanks for bringing us Fred's home page, pinhead! Most intersting!!

  • BwummerBwummer Posts: 46
    Good call on the hills, darenjpdx. The TDI feels much spunkier than the GLS going uphill, especially if you need to accelerate.

    Now I know Connecticut doesn't have mountains quite like the Rockies, but some of our inclines are very steep (7-8%) over short distances.
  • BwummerBwummer Posts: 46
    The official word from a TDI owner is: "Underpowered, shmunderpowered."

    Yes, compared to a Viper. But because of the torque range of the diesel, it has much better low RPM pulling power than the gas engine. If you think you're running out of power, and you're above 3000 RPM, shift to a higher gear and bring the RPM back down to around 1800-2000. Your TDI will FLY.

    Complaints about underpowered cars probably come from people who are used to driving gas engines, which don't generate peak torque and HP at the same RPM's. They wonder why at 4200 RPM their diesel isn't pulling as hard.... (Hint: maybe its not designed to :) !!!).

    You only run out of steam above about 3600 RPM in 5th.... by which time you're already going 90MPH or so. If you want to qualify for the Winston Cup, find another engine. If you want to go from point A to point B at mostly legal speeds, it's a terrific engine choice.
  • Just a quick update on mileage in my Beetle TDI. A half tank of in-town stop-and-go traffic over short distances to work resulted in only 34 mpg. My Grand Cherokee 6 cyl gets under 11 mpg in the same setting. But the next tank took me to 450 miles with more than a quarter tank left and netted 47.7 mpg (all highway miles).

    This is a repost from the New Beetle board. I thought the experience was appropriate here, too.

    I just pulled into a Full Service station (in New Jersey, where they have so much unemployment that you can't pump your own gas), and the yo-yo already had the regular fuel hose out and was ready to fill my poor TDI with that nasty stuff. I said, "Fill it up with diesel, please," and he
    TANK. Then he caught himself and said, "Did you
    say diesel?" I told him I had. He replied, "I
    didn't know these things were diesels." Sigh.

    Well, at least I didn't actually PUT unleaded in my tank (unlike the Edmunds crowd).

    I've owned a VW diesel since 81 and can say that they're extremely durable. My Rabbit was still running like new after 230,000 miles when it was wrecked last year. I bought a NB TDI and after 10,000 miles, can say its another winner. I was stunned by the power compared to the Rabbit! Others have already commented on the great low-rpm acceleration, and I agree. And I like the deep growl the engine makes.

    A trip from Portland, OR to Sacramento was covered in less than one tank (49) mpg at speeds up to 85 with the AC blasting. It was just cruising along at low rpms without any strain.

  • Just filled the Bug again. MPG? 51.2!!!! Kewl, man!

    At this rate, I'll soon be able to afford food again.

    Since mid Dec., when my wife bought her NB TDI, she has saved enough in fuel bills to pay more than half the payment. 42 avg. local on winter fuel! Might have to buy one for myself with that kind of justification.
  • govugovu Posts: 62
    When I stopped by my VW dealer the other day to check on the arrival of my TDI New Beetle, I took a Jetta TDI out for a spin. After my half hour out, I walked away more excited than ever. What a beautiful engine! Plenty of oomph and a total joy to drive. I can't wait! I'm seriously considering not being so picky in my color choice so that I can get my hands on one now.
  • lucien2lucien2 Posts: 2,984
    you know, I cannot understand Road and Track Magazine's attitude about the TDI. They say it is too slow, but then the track numbers show that it is only 1 sec. slower than the gas engine (and let us not forget that the test driver may be shifting as if in a gas powered car, over-revving the tdi, losing out on the torque, and therefore not turning in the best run). I actually cancelled my subscription, primarily because the editorials are always strident, anti-environmental, anti-safety rants. C'mon, guys! We can be responsible and still drive sporting cars- VW tdi proves it. Moreover, LOTS of cars are available in Europe with a tdi of some kind. The U.S. market is way behind. I for one don't believe gas prices will stay low forever, and then where will the gas sucking insurance nightmares these editors love so much be? In the driveways, making room for all you TDI owners to zip around the twisties! I don't own one, but am seriously considering it. I wish there were more choices than VW and Mercedes. I really need a wagon, but can't afford to spend over 18K or so. Golf may be a compromise, or I might wait for the Ford Focus, which promises to be sporting and effecient (and ULEV compliant...). Of course, the new Ford 1.8l TDi will be a Europe only power plant...*sniff*

    The praise just keeps on going. I bought a Jetta TDI in July of 1998. I have 19,000 miles on mine and it has been perfect. I have averaged 47 MPG overall, you will get spoiled by that. The fact that you can routinely drive 600 miles between tanks is wonderful. I have not had any trouble starting in the morning and that is accounting for sub zero weather. The diesel is quiet compared to the Mercedes 300D I traded (it is loud when cold in the morning, sounds like a John Deere and I like it). Great car and great engine. Can't wait for the V6 TDI to come from Europe. Then I can finally get me Passat.
  • Lucien --
    Now you know why I subscribe to Car and Driver and Motor Trend, but not Road and Track.

    C & D measured the TDI at about 0.4 seconds slower (11.2 0-60 vice 10.8 for the gas). That's less than the average human's reaction time. I completely agree that anyone who complains about the TDI's lack of speed or power probably doesn't understand the differences between a diesel and a gas engine and is driving them the same way.

    Two days ago, we had a huge (8") snowstorm, and I confess I was worried that the diesel's high low range torque would cause it to spin the wheels. I shouldn't have worried. With 4.5" of unplowed snow in the driveway, my wife (in the TDI Beetle) purred out of the snow just as easily as I did in my Explorer, even crunching through the barrier of snow thrown up at the end of the drive by the snowplows without a hitch.

    And Lucien, if you really want (or need) a wagon, check out the Passat wagon. Don't know if you can get it with a TDI, but both C & D and Consumer Reports loved it.
  • lucien2lucien2 Posts: 2,984
    well, I did test a Passat and loved it, but I hesitate to commit that much disposable income to a car payment. New Passat is out of reach, unless I save a big down payment- I bet that if I have a 6k chunk of cash laying around I may have a problem handing to a car dealer..I may wait until a few Passats show up used, for around 18K or so. For the moment, I'll keep tinkering on the old 4Runner.
  • rdeschenerdeschene Posts: 331
    lucien2. Yes, with $6000 cash around, it much easier to put it into an RRSP or IRA than a car (depreciating asset) downpayment, isn't it?
  • BwummerBwummer Posts: 46
    .... that is the question. Whether 'tis nobler in the mind to suffer the stings of your friend's arrows for lack of a new vehicle, or to take arms against a sea of dealers...

    Sorry. Carried away there.

    Actually, I've frequently stated on other boards, few people really need to buy a car today. Most of them just WANT to buy a car today, because a new one is usually nicer than an old one.

    For my money, if you have $6K lying around, invest it in a growth fund at about 25% return, then add $250 per month (which is much less than the average car payment, plus you don't get in trouble if you have a bad month and can't pay). In three or four years, you'll be able to pay CASH for a new vehicle. I put $1000 in a college fund for my son when he was born, and have religiously added $100 every month since. He's now 27 months old, and I have $4750 in the fund. This means that I've made over $1000 in dividends and capital gains in 2 years. With a little more aggressive strategy, you can do the same thing over a shorter period and get a car. But you have to be willing to wait....

    I think it's important NOT to fall victim to the new car bug; don't get less than you want today just so you can have a new car. Save for the one you really want!

    On the other hand, marrying someone rich is also a good strategy...

    Also for the record, I've only ever owned one car that wasn't a VW. I think they're worth the extra money.
  • I have a question for the TDI owners out there. How long does it take before you get heat from the vents? I love the thought of 50 MPG, but is that thought all I will have to keep me warm while I'm driving?
  • pinheadpinhead Posts: 33

    I have a 99 NB TDI and we have had 15 deg F mornings for the last week or so. Heat has NOT been a problem! Don't worry about it.

    Starting. Also not a problem. Go for it!
  • rdeschenerdeschene Posts: 331
    Travis169. Hedge your bets, man. And no, I don't mean: "sell S&P500 puts at the current price"... well not necessarily.

    Price out electric car heaters and get measurements so you can figure out where in the car you would put it. If worse comes to worse, this is what you would have to live with. I've driven in toques and mitts through several winters, just waiting for my gas-fired car to warm up. If you're in the contiguous-48 it shouldn't be any worse than that.
  • darenjpdxdarenjpdx Posts: 14
    The TDI heats up just as quickly as any car I've ever driven and provides tons of heat to the interior. Don't worry about it.
  • corvettecorvette United StatesPosts: 6,665
    This is off-topic, but... The bull market will not last forever, and I only invest money I know I won't need for 5-10 years. The thing to keep in mind is that if you invest money for a new car and the market goes down, you will have to ride it out (leaving your money in) for at least another 1-2 years. It's also important to pick a good fund, most of them don't even beat an S&P index fund (a fund that requires zero brains to manage). For more info, check out

    Paying cash is definitely the way to go.

    For something on topic to add substance: Does anyone know if/when the TDI will be available with an automatic?
  • dae3dae3 Posts: 55
    I read a review that said the TDI doesn't have any power to pass at highway speeds and that passing on a two lane road would be dangerous. Is this just another case of the reviewer not knowing how to drive this car or is it a fair evaluation. If an owner could respond that would be a great help.
  • govugovu Posts: 62
    The owners will be able to give you a better testimony (of which I hope to be included -very- soon), but in my test drives I've had no problem with that. Sure, it's not a V-8 by any means, and it's certainly not going to be like driving a Corvette, but the engine had plenty of pep. The way I was driving it, my girlfriend thought that maybe I should buy a car with a little less under the hood.

    The owners I've talked with have been very enthusiastic about the engine. It seems like the TDI owners LOVE their cars even more than those without TDI, if that's possible.
  • pinheadpinhead Posts: 33
    I have a 99 NB TDI and there is plenty of power. And if you want more, 115hp and 185 ft/lb is a chip away!

    I love my TDI, but it honestly took about a week to learn how to drive it properly.

    Hwy cruising is a blast, 70 mph is a lazy 2400rpm. Need to pass? Push your foot down and you'll be @ 85-90 before you know it. The most fun is passing the gas stations!
  • dupperdupper Posts: 6
    I own a 1996 Passat TDI wagon. GVW is about 3200lbs, the largest US auto VW makes with a TDI engine. In the 64K mile I have put on this car passing power, starting, heater performance and overall quality of this vehicle has NOT been a problem. Those among you out there in the baby Beetle , Jetta'a and Golf's who may be concerned re. the above, don't worry about it...enjoy the ride past the fuel pumps, just my .02
  • mjb56mjb56 Posts: 170
    Whoever wrote the review claiming that the TDI NB lacks sufficient passing power has no clue how to drive this vehicle. Just got mine out of winter storage and I forgot how much fun it really is. The only time I see power drop off is at 85-90 mph. Then it flattens out a little, but who in their right minds wants to drive like that. Trust me, power is not a problem with this car. Oh, and by the way, my last tankfull showed 44-45 mpg in mostly city driving.
  • ddeebleddeeble Posts: 2
    A couple questions for you TDI pwners out there! I am now in the process of picking my next car (I currently drive an '86 Mustang that gets in the teens for mileage and commute 120 miles to work each way) and the TDI engine in the New Beetle seems like a dream come true - 49MG!!! My wife and I crunched numbers this week and it looks as though the gas savings alone will cover the entire cost of the car! My questions are these - I have seen a couple of postings stating that the TDI s 50-state compiant, but when I go to there is a California Emissions option listed at $100. I may be buying the car out of state since TDI's appear to be in short supply in California and don't want to get dinged with the $300 polluter penalty the DMV levies. Has anybody done this before and what was your experience with the DMV? Second: As I stated before, TDI availability, as far as I have been able to tell, is atrocious in California (I live in Sacramento) - does anyone know a dealership anywhere in the U.S. which seems to have a decent supply of TDI New Beetles (or who the 5 largest VW dealerships in the U.S. are)? The only one I have been able to find so far in Sacramento was a black TDI with damage to the hood incurred during shipping (and they still wanted $2500 over MSRP!) I would greatly appreciate any help you may be able to provide!

    Thanks you all!

    Does anyone know if the new Golf is available with the TDI. I haven't seen one. I know it was supposed to be an option.
