    Default XM Economy

    Hi,
    Would anyone be able to help me with the economy figures of a 2.0 l XM, turbo and non-turbo?

    Thanks, Prav

    Praveen, the words XM and economy together consitute an oxymoron.

    I suppose a 4 cylinder one would be more economical than a V6 though. The only time I can get my V6 (12v) auto below 10l/100km is on a long trip, when I get about 9.5l/100km.

    You might want to ask this on the yahoo list, quite a few 2.0 XM's there, only one that I know of in Australia and he does post sometimes.

    General consensus seems to be that the CT turbo is the best compromise (unless you go for diesel ).

    Thanks for your replies, have posted on the XM forum as suggested. Certainly not looking at running a V6, thanks anyway Roger :-)

    Sometimes he does. And he reports that his 2.0i non-turbo gets around 12.5 litres per 100 km around town (not great - it's a big beast to lug about). The good news is that the long trips are around 7.5 - 8 litres per 100 km.

    Hey Greg, I saw your mighty machine the other day while it was in Elliot's joint getting its strut towers fixed. I can't believe how much rooms there is under the bonnet, you could throw a party in there. I don't reckon you could fit a footy in amongst my V6 and shut the bonnet. Having recently pulled out the main high pressure pump outlet pipe to silver braze a vibration hole (caused I suspect by the Sydney specialists not reinstalling all the stand-offs) I know how hard it is to do any work under there.

    I was asking him about the Spanish spheres and buying some LHM. He didn't ask me to pay, when I pay for the sphere will be fine, but who knows when that will be. And this the first time he has met me! But hey, I respond well to being trusted.

    Roger, that damn HP line gives me the absolute &^%$#*(&%. I have had to repair it twice on mine now due to vibration stresses or rubs. "one day" I am going to get Pirtek etc to make me a nice strong rubber HP hose with metal ends.

    The low qual pipe they use from the factory and the torturous route it follows contribute to its demise. IIRC, this is not an uncommon V6 XM problem.

    Yes Roger, that was the Dark Shark with its itty bitty power plant. I carry my 205 GTI in the XM engine space as a spare. The XM was a good conversation piece in Elliot's garage, apparently (eg "what happended to the engine?").

    BTW, Elliot has been a pleasure to deal with. He's new to XMs, but kept me informed with all the work all the way, and tried hard (and overcame) various obstacles. He's getting work from Shannons (wonder if Dogboy put in a good word?) and his shop had a lot of interesting automotive exotica yesterday when I picked the Shark up.

    You might want to give him a ring about the Spanish spheres - his supplier couldn't get them for my XM. The least expensive way of obtaining new spheres that I have found is to have them shipped from GFS in the UK - works out at around $76 per sphere, including postage.

    Now that the struts and spheres have been seen to, I'm off to get a set of Michelin XM1s.

    Regards,

    Hi Greg,

    Could you give us an update on what happened with your struts? Did you replace the rubber bit or the entire strut?

    Agree on the spheres, just had a new accumulator sphere arrive from GSF nothing easier. Now I just ahve to install the thing.

    Hi Sean,

    Rusted strut top also had small cracks in the rubber, so bit the bullet and replaced the whole top assembly. Elliot's part supplier didn't believe that the standard series 1 strut top for the V6 would fit my car's front strut, however the advice from Willy Johnson in Ireland proved correct (and was corroborated by the parts catalogue). A series 1 strut is a series 1 strut, it seems. I provided Elliot with the Series 1 and 2 XM parts catalogues and the BX Series 2 parts catalogues on a CD ROM, so he can now win arguments with his parts suppliers.

    Replacing the rear anti-sink sphere was apparently a rotten job - I recall Shane and Roger's account of doing the job on Roger's car last year. Never been replaced, and wouldn't budge without major persuasion.

    Now with all new spheres and new Michelins, the car's ride is smooth and quiet (and doesn't sink in a hurry). Looking forward to driving it down to Westernport Bay tomorrow morning.

    Hope this helps,

    Regards,

    Greg

    Thanks for the info, a few other jobs to do on my XM and then I plan on replacing the struts as there is no record of them having been done and I figure they must be getting on a bit.

    Replaced the centre spheres when I first got the car and would definatly do this again- they really do make a difference. For better or worse mine dosn't have anti-sink.

    regards

    Are you sure? Looking at page 730 of the parts manual, I can't see exceptions to anti sink identified. There are evidently some cars without hydractive, but they still seem to have the anti-sink spheres.

    Sorry Praveen, we XM types have completely hijacked your thread.

    Greg, do you really mean anti-sink sphere? My rear centre sphere that was tricky to get to was the hydractive sphere. Like Sean's, mine does not have anti-sink. I thought anti-sink came out later than our cars. Mine wasn't all that tricky to remove. You need to get the car up high enough, and Shane's mega-ramps were great for this. Then you have to find the sphere, hiding behind a large cover plate. Then you have to get the cover plate out, and this was the hardest part of the job. I had to flex and bend it a bit to get it out. The sphere itself wasn't hard to screw off (Australian delivered car, remember). Getting the cover plate back on was nearly as tricky as getting it off. It was held on at the rear by a couple of cable ties and it was pretty tricky getting the new ones on properly.

    How many spheres did you have to order from GSF to get them for $76 each? And did you just get the standard spheres? I am considering getting estate rear spheres for mine because their dampers are larger (0.70 instead of 0.50 for the hatch -- what does that figure mean, can anyone tell me?). The car has makeshift spheres on it, CX rears and half flat GS accumulators for the centres, and I'm starting to get used to the floaty ride.

    I'm pretty happy with the new Michelin XM1's on the front of mine. Just waiting to wear out the MXV2's or 3's or whatever they are on the rear so I can put new XM1's on there too.

    Elliot's main parts supplier, Alain Newton, is French too. They probably talk in French to each other. I have spoken to him but he won't sell directly to you unless you are in the trade.

    It was only series 2.5 XMs (in Aus 24v V6, AL4 auto box etc) that had anti sink. They are "easy" to identify as they have the 6+2 pump mounted on the lower right of the engine and do away with that bloody awful metal spaghetti that joins the pump to the FDV on the 12V.

    The easy way to get the centre rear hydractive sphere off is to have a non standard exhaust fitted. This does away with that huge secondary muffler that sits crossways and replaces it with a smaller unit that sits in line. A little more gurgly but still fine at highway speed. I can now take the shield off with no bending, reach up and remove the sphere, have a party in the spare space, etc etc. A bonus is that after easily removing the spare tyre cage it is easy to remove the fuel filter for changing.

    Have been running XM1s on my XM for a while (well the name matches!) and they are quite good.

    Got 2 front and 2 rear GSF standard XM spheres and now I wish I had bought the comfort model. Roger if you are buying I suggest you buy the comfort option.

    Mine has the original exhaust system in it and it is showing no signs of dying. I'm not paln ning to replace it so I will just have to put up with the hassle of removing the shield every so often.

    I'm keen on the comfort spheres. I need 2 main rears and front and rear centre hydractives. Problem is my 2 main front ones are the super-dooper diaphragm ones with dimples, and they are right up to spec on pressure whereas the 2 main rears had 5 and 8 bars in them and the 2 hydractive ones were completely dead. The car now has pretty good CX rear spheres and half charged GS accumulator centre spheres (they were the most suitable Shane could find lying around!). I've got used to the floaty rear so will definitely go with comfort ones there but I can't bring myself to replace the front ones.

    I have comforts spheres on the rear of mine (came with them) and have never found it too soft.

    I think the fronts need re gassing so if they are dead I will be looking for long life spheres to replace the regular spheres there now. Anyone know of a source of long life spheres?

    GSF charged me 40 quid for accumulator sphere and postage so $76 sounds like a good price to me.

    If your front spheres are dead or near to it replace them REAL soon otherwise you will be following up with a strut mount, bonnet......

    Roger - the irony of having the exhaust replaced was that the stainless inner was still "perfect" well... But the mild steel outer was rust city.

    Prav,

    Sorry this thread keeps veering away from fuel economy. That said, the thread perhaps illustrates that a well-sorted XM is the car to buy, regardless of the model.

    Sean,

    I suspect there's some discount for higher volume, and/or the accumulator sphere is more expensive. My GSF quote was based on buying all seven spheres, including postage, then dividing the amount by seven. Postage and handling for an indivual sphere seems likely to be more expensive.

    Roger, Craig - Apropos of anti-sink - I still have a lot to learn! ("What's this button for?" exclaimed Captain Feathersword).

    Anyway, have just arrived in Westernport after a 70 km drive with the new tires and spheres, and it was a very pleasant experience (not enough corners though!). Car is much quieter and the ride is very smooth. Was pursued by a '92 Saab 900 Aero for much of the journey, which couldn't stay with the XM through the roundabouts.

    Regards,

    Greg

    The funny bit about the 'anti-sink' sphere your that gets discussed.... Actually has nothing at all to do with anti-sink. The anti-sink system is just a pressure differential valve that shuts off fluid return.

    The 'anti-sink' sphere is actually a rear brake accumulator Replacing it will have absolutly no effect on how quickly the car drops (after all if it was anything to do with 'anti-sink' both axles would need one).

    Found this salted away on my Hard drive. Test figures only but at least it provedes some way to compare.

    As noted above all this only goes to prove that an XM will make you very happy.

    ..provided you don't own the 3.0 litre.

    *happiness, in this case, being related to low fuel consumption only. Comment does not include happiness relating to and/or contingent upon all other aspects of XM ownership, living or dead, insofar as happiness and car ownership may be construed to have a causal relationship and not merely a correlation, etc, etc...

    By the sound of it they do know what they are missing - the increased fuel costs. However, when you need the go ya got it in a V6.
