I have had my CRTD CDX auto since Jan this year and the BEST I get is 27mpg average. My driving is equally divided between motorway and town.

Not good fuel consumption.

:(

I've been looking at 'Parkers' website and the owners revues for the 2.0 lite diesel in the heavier Santa Fe. A number of them report averaging 40mpg solo and getting around 30 mpg towing. Now I believe this the same diesel engine as in the Tuscon, so why can a heavier car with the same engine acheive FC figures that most Tuscon owners only dream of? Only a thought!!!!
Good to hear that Hyundai seem to be taking this problem seriously. I've also written to Hyundai and I am awaiting a response.

See theNew Topic entry Help required from Itsatusconmatey and send your details re fuel consumption to tuscon.dieselmpg@virgin.net

Thanks
Geoff

Thanks Grimfish
The only problem with the report is its by the American Government and is based on US Gallonage, Us Brits have the Imperial gallon and pay through the nose for it.
Current UK Price for a UK Gallon is £ 4.13p or $A9.62 a gallon US $ 7.35.
Our government adds about 70% on to the cost with Tax and VAT (Value added tax! )

The main contention of UK Buyers is that Hyundai issued brochures and in these it advertised that the vehicle would do a certain mileage to the gallon, It didn't say that the guide was a US based figure so any UK Purchaser me included looking at the figures thought the vehicle would be an excellent purchase.
In the UK SUV's and 4x4's have only just started to be used by drivers (In any number anyway) We can therefore only rely on figures quoted by companies regarding their products.
The Hyundai Santa Fe actually does more to the gallon than the Tuscon but equals it in the published figures.
Documents published in the UK for UK purchased items should be correct and that is the way most of us feel(as I read it).If the figures had been lower then Hyundai would probably not have sold any Tuscons in this country. The Odd 10mpg that we are not getting to the gallon equates to 25% extra fuel per tankfull/ miles

The Tuscon 2.0CRTD is £17200 in of taxes thats a whopping A$40,076 what did you pay for yours?

Sorry to go on but I'm compiling the figures as acurately as I can and anyone who will help send me your consumption figures for my excel spreadsheet at least then maybe Hyundai will adjust the figures and make them accurate for UK Byers.

Send your facts to tuscon.dieselmpg@virgin.net

Thanks

Geoff

I've read somewhere (on this forum probably) that turning off the Traction control (TCS) has a dramatic effect on MPG. Does anyone have experience of this? Could a malfunctioning TCS be one possible source for the high FC?

I note that one or two people are getting particularly bad mpg from the CRTD -low to mid 20's, while a majority are getting around the 30 mark, and odd one or two get mid 30's mpg (which is still far below that stated in the literature and website) Variation is to be expected but are these results indicative of more than one casue for the poor MPG?

I would also be very interested to know if switching the traction control off makes any difference to fuel consumption

BUT

The figures quoted by Hyundai make no mention of doing this or turning anything else off in order to achieve their claimed MPG.

You may be interested to know that all the tests carried out on cars within the EEC are in Lab conditions on a rolling road and are completeely independant of the motor manufacturer. They are not tested on a road under "real" conditions. The test equipment is set up so every car is tested under exactly the same conditions i.e the pad that pushes the accelerator down uses exactly the same pressure on every car so in theory it has to be representaive. In most cases this does appear to be accurate to within a few MPG but in the case of Tucson it is so far out its unbelievable.The figures in the brochure by the way are UK gallons despite the fuel trip being calibrated in US gallons.The main difference on the Tucson compared with other 4 WD vehicle is the ability of the car to self select 4 wheel drive when needed although I have never notice it come in (does the light come on?) and the heater on auto will alternate between the screen ( which activates the air conditioning unit.)and the footwell. Both 4 WD and air con is a know factor for gobbling fuel and I would suspect if we ever get an answer for Hyundia these 2 factors will be a major contributer to the gas guzzlers appetite for Diesel.

Hi All,

I'm back - not been online for a few weeks, and its really interesting catching up on all the recent posts. I'm amazed at how many posts are on this thread now!

Regarding comments about the effect of TCS and 4WD - I have given info on my own tests further up this thread. Basically NO - TCS doesn't affect it, and 4WD would - but it disengages above 20mph, and you definitely know when 4WD is engaged at low speed and turning corners. My conclusion was that unless there is actually something wrong with either of these, in normal driving conditions they are not responsible for high MPG as all of us are experiencing on this thread.

Now, take a look at this forum page for a Toyota RAV4. It gives an idea of MPG that the RAV4 gets. You'll have to make your own mind up as to how it compares to Tucson because some RAV4 owners are happy, and some are not! Some believe their fuel computer, while others do proper MPG tests.

http://toyotaownersclub.com/forums/index.p...pg++consumption

I thought it was quite amusing in a way because the Toyota crowd seem to be experiencing very similar problems with fuel meters and consumption. Its like looking in a mirror! :wink2:

My Tucson has now gone over 5000 miles. And its not doing any better.

I had been waiting for Bob Brampton (Hyundai UK Cust Svcs) to ring me back on April 2nd (he absolutely promised he would) but he didn't, so I left it for a while to give him the benefit of the doubt. I got fed up of waiting, so rang him yesterday and he said he hadn't rung me because there was nothing positive to tell me. I said that every customer services dept should return calls when they are supposed to, whether there's good news or not.

MPG Testing

Anyway, he reported that their UK engineer has been in Korea for the last few weeks assisting with testing. This is *apparently* in progress but is taking longer than he originally thought and and there will be nothing to report until mid to late May.

Hmmm - buying more time from our warranties? (an old cynic me!)

New UK Gallon MPG Computer

Bob also said that from June the factory lines will be producing a new MPG computer meter calibrated in UK gallons in new Tucsons. He wasn't able to say whether there will be a retro-fit for existing customers.

He promised to keep me informed on any progress.

He also told me they recognise there are various problems reported by a couple of customers with Automatic drive Tucsons. I reminded him that mine is a Manual.
He mentioned some customers have had brakes binding, and some with the auto gear changes not working properly.

He says 9 of *his* customers have reported they are unhappy with fuel consumption.
He also said that he knows of some of the other Hyundai franchises around the UK who also have customers who are concerned. (I would have thought that being central UK office they would know exactly how many customers this equates to, but perhaps he just doesn't want to say).

If Toyota RAV4's do genuinely manage higher MPG than us then I would say that the Tucson should be able to match it, and therefore Hyundai's engineers MUST come up with a solution.

I also believe that the Tucson 2.0 CRTD can manage 35 or even 40MPG but ONLY IF YOU DRIVE LIKE A SNAIL !!!! i.e. 45-50mph. But none of us have the time to drive like this and it takes all the fun out of driving it.

Thats all for now
Jim

sorry, i have been twice with the tuscon.

garethr,

That must be very frustrating!
I know I would be a bit peeved!

Sometimes I think maybe I should have got the petrol engine which would have been more fun to drive and probably just as economic as the Diesel.

I drove a friends Santa Fe 2.6 and I loved it. But I thought I would go for the diesel Tucson to be more economical.

Maricha - the problem is that the Tucson is very greedy!
Its a naughty Tucson :wink2:
It burns holes in our pockets.

With regards cold weather, perhaps technically it would improve consumption, but it all depends on the persons right foot, which far outweighs any amount of extra oxygen that might be in the air at a few degrees difference in temperature.

But regardless of how much diesel the Tuc uses, after 5 months of driving it, I still like to get in and go! Its a nice motor. :)

Jim

Hello I have been watching this topic for a little while now,I have a 2.0 crtd CDX and I am getting around 27 MPG all local at the moment it's only been on the motorway once.

I got rid of a freelander to get the Tucson and have not looked back since.

I've now received a reply from Bob Brumpton at Hyundai UK. He suggests that its too early for an accurate assessment of mpg on my Tuscon and would consider 3000 to 4000 miles necessary for the engine to be 'run in'. Its at this stage that he believes a true assessment of mpg would take place AND that mpg would improve by this time. I hope so - what do others think?

By the way I was chatting to some friends about my low mpg and they said that they noticed a marked improvemnt in the mpg of their Vauxhall Meriva (deisel). When new they were getting around 40, now after 7000miles they're getting around 50 - so maybe its true!!!!

Don't hold your breath. I've now done 5000 miles and any improvement is minimal.

Brian

Ditto.
Sorry, but no improvement after 5200 miles.

Hmm. Maybe we should have gone for a Vauxhall Meriva for the 40mpg to start with!
After 5200 miles I'm still getting only around 30mpg.
I'm about to fill up again tonight when I will do a calculation, but so far on this tankful I've only done about 310 miles.

Pie2000 what did you get MPG in the Freelander?

Jim

The Freelander was V6 auto so I only got 15 MPG around town. I am a member of the landrover forum and the Freelander TD4 members get around 34 MPG.

Yes, well 34MPG I would be happy with.

Tonight I filled up with 52 litres which is 11.43 gallons, and I had done 319 miles, so thats again a rather poor 27.9 (say 28) MPG, driving what I would consider to be normal, not excessive, and not careful, just normal. And thats after 5200 on the clock.

Perhaps I should consider some radical action like;

a) put a wooden block under the accelerator so I can't push it down too far
B) wash it with plenty of Turtle wax to get a beautiful shine for less air-friction
c) put a streamlined nose cone on it like Concorde
d) pull up close into the slipstream of lorries
e) get a big rope and hook so I can latch onto other vehicles for a free tow
f) ask my boss for a pay-rise due to increased fuel costs

Any other bright ideas?

Come on Hyundai, surely you've got something wrong somewhere?

:unsure:

Hi Jim :57:
I've sent off a letter to Hyundai complaining re my fuel usage :angry2: but I still seem to be doing more than you ! On average I'm getting about 31Mpg per fill.
For a thought what fuel you using? I've heard that Tesco or supermarket fuel isnt as good as shell or BP.
Saw something on the internet that stated that certain additives were put in at different times of the year basically to thin the derv in winter. Maybe out Tucsons dont like this additive.
Have u thought of getting a chip to increase power etc apparently when these are increased then you arn't as heavy with ur rt boot and you get a better MPG.
I am awaiting some details on chips ex Germany and am contemplating Purchasing one for myself(£100) only I dont do that much mileage a week now (I cant afford the diesel now I'm on a pension)
I had planned that this was to be the car to take me to 2010 but perhaps 2005 is more than possible...but the Tucson does drive nicely and it looks good,, but if it were a person it would be over the limit every 31 miles (If you get my drift Hic Hic)
I met up yesterday with Richwafta his 2.0 CRD has done 4000 Miles + and returns 34 MPG but he travels 30 Miles each way to work and mostly on the Motorway.
We need more people who dont like their fuel consumption to contact me on
tuscon.dieselmpg@virgin.net

Giving Details of MPG returms so that I can complete a spread sheet to send to HYUNDAI to back up our Claims . Hyundai say only a few have complained that cannot be correct surely..
