There has been several discussions concerning fuel consumption figures; the EU method of measuring the CO2 emitted has well known flaws, these are generally used for Taxation use on Company cars.

The Eco, so called "green" cars manufactured by BMW (318D), Ford Escort 1.6TDCi style, VW Golf 1.6TDi 105S, purchase & running costs actually costs more than the standard vehicle, over 36000 miles.

The KIA 1.6CRDi 90PS does save money, albeit there is less power than the 115PS standard version.

The  Hyundai i30 CRDi 1.6 (No DPF), real (uk) world motoring figures, show Mixed Use 51.5mpg, Gentle 64.4mpg, Urban 33.9mpg & Motorway at 70mph 49.6mpg. It was carried out by measuring the actual amount of diesel used, and not from the on board computer. The air con was not used (UK!).

This is discussed a lot in the UK press. The major issue is people buying small diesels and then running them around town all the time, where they don't get the economy benefits of stretching the legs on the diesel.

Of course the diesels cost more to procure, so there is always going to be a hurdle to get over for the break-even point. I doubt it's exactly 36,000 miles for each of these cars, it will vary a bit. The chain-cam diesel's in the Hyundai's give them a slight advantage here, as they don't have those so-frequent costly belt changes that some require.

With regard to the flawed method of measuring co2 and economy figures, it doesn't matter, as long as the same proceudure is followed on each car, at least you can get some kind of comparison. If you are keen to replicate the test results you will of course most likely be disappointed.

Lorian, thanks for your input, good points, well put.
As finally stated in my report, those figures were based on UK tests. Our climate is somewhat different than say Southern Spain, that is clearly the real reason for EU testing in laboratory conditions. EU countries climate and conditions all vary greatly, as would the climate in an Australian summer compared to a Finnish winter.

In the Publishing World, (I am not), headlines rarely sell  stating "Dog Bites Man" - boring, but "Man Bites Dog".............that's different.

I have offered another insight, as you have.

Ah, I think the final two paragraphs appeared after my post.

I didn't know they made the 1.6CRDi 6 Speed without the DPF.

[Mike SX]

Lorian,
Both the Dealer and Hyundai themselves (after a lot of probing), said there was no DPF, mine is a 1.6CRDi. I get the feeling that you may be in a more favourable position to find out, I would be very interested.
Incidentally, I understand KIA have no plans to install DPF's in vehicles used as predominately around town  Taxis - KIA seem to be Taxis Owners favourite no DPF vehicle.

Only by taking a look

Here is where it would be if you have one, the big canister on the back of the engine by the turbo,



This is what it looks like on the car, a kind of cylinder browny coloured, just a little further left than where the arrow stops, you can see a big plug just going in to the top of it.

I don't think they will have any choice soon on the 1.6CRDi (High power) in the UK as it wouldn't meet EURO5 emissions without one. The specific type of DPF used by Hyundai (and presumably KIA) is Aluminium Titanate type, which is reported to be possibly better at coping than the type fitted to a Focus, for example. I am no expert, it's just what I read.

They might of course have a real mean map for the low power motor to achieve the same.

[Mike SX]

Lorian, Yes, you are correct, it looks like I have a DPF, my i30 CRDi was the first 6 speed the Dealer had received, and both them and Hyundai Technical Support gave me outdated information.
They told me the DPF would be subsequently fitted to the 1.6CRDi.

However, the tested i30 5 speed (and i20, tested simultaneously October 2009) in the reports did not have a DPF's.

I will also check our new i20 when the Wife returns from France.

[Mike SX]

Lorian,
Would you happen to know the difference in the CRDi(i in red) and the CRDi (i in green), I was lead to believe that one of the differences was the DPF.
I am grateful for your assistance; road testing on i30 and i20 were being carried out by Test Engineers adjacent to our offices last October when the subject of DPF's came up, and they explained the significance.
I simply trusted the information from Hyundai, and would like to know.

[Mike SX]

 Lorian,

I have posted a statement on 6, and a question on 7. Sorry should have replied here.

[Mike SX]

Lorian,

Yes, our i20 also has a DPF.

I had understood that with a DPF in place it was difficult to measure the actual amount of fuel used, over a certain period, because from time to time the DPF would "burn off", and use excessive fuel, which would plunge the figures downwards, and you never knew when it would happen.

Apparently, that is why the vehicles tested last October, had no DPF's.

As a general rule I think if it has a 6 speed box (and is a 1.6) then it will have a DPF. Whilst the DPF is not mandatory until 2011 to meet EURO5 emission regulations, they seem to have been shipping it since about August 2009 production in the Nošovice plant.

However, the tested i30 5 speed (and i20, tested simultaneously October 2009) in the reports did not have a DPF's.

I don't think any 5 speed i30 CRDi's have a DPF they just have a DOC (diesel oxidising catalyst). The new ones have these too as well as the DPF, I believe (but have not looked).

Would you happen to know the difference in the CRDi(i in red) and the CRDi (i in green), I was lead to believe that one of the differences was the DPF.

I  *think* a red i means the higher powered engine, and the green i means the low power version, but I think this may vary from market to market. My high power, DPF equipped model has a RED i. Models equpped with idle stop and go should really come with a blue i, but I have yet to see one.

Yes, our i20 also has a DPF.

The i20 gained the U2 before the i30 so its possible its been shipping with a DPF for longer, maybe since launch.

Hyundai employ a  Corning Duratrap AT (Aluminium Titanate) DPF which is considered to be a  "Next generation" DPF - unlike on some older cars I think it does NOT require a burn phase, and it has a natural ability to cope with higher ash loading. I am not an expert on this. You can read lots about it by googling "corning duratrap AT". Hyundai/Kia were first to sign up for this new type of filter, and I note Ford and Volkswagen have recently too.

You may also find this presentation of some interest.

and this press release

http://www.hyundai.no/Hyundai_U2_diesel.html

If I owned and i20/i30 with a DPF and drove it round town exclusively, I would still give it a good run occasiionally for the benefit of the DPF as well as the rest of the engine.

Keep in mind DPF equipped cars oil must meet ACEA-C4 spec, and you cannot rely on a dealer to get this right, always worth double checking with them!

[Mike SX]

Lorian,
The information you have provided to me is simply outstanding, thank you very much.

[Mike SX]

Lorian,

  I have read the Hyundai U2 release, although my 1.6CRDi 6 speed has a sticker on the front door jamb stating 115PS, and Czech manufacture, the article says the U2 has a 128PS output, my Sales Invoice states U2. Am I missing something, please don't say 13PS!

[Lorian]

Lorian,

  I have read the Hyundai U2 release, although my 1.6CRDi 6 speed has a sticker on the front door jamb stating 115PS, and Czech manufacture, the article says the U2 has a 128PS output, my Sales Invoice states U2. Am I missing something, please don't say 13PS!

You have a U2. The 6 speed gearbox is only available on a U2.

In europe currently the U2 engine is mapped to only produce 115PS (113BHP) for three reasons:

1. It saves the costs of re-testing the car
2. It allows the car to stay (just) under the 119g/km co2 figures that are VERY important for the UK market as it means road tax is just £35GBP per annum.
3. It keeps the car in the same insurance class as the previous U variant.

You do however get a little more torque over the U variant, and get a quieter engine, 6 speed box, dpf etc. I doubt you would notice the extra 13PS too much, as you already get the extra torque on offer anyway (5NM)

This will naturally lead to some more questions:

1. Does this mean there will be a 128PS i30 sports model sometime?

My guess is not in the current economic and regulatory climate. It is more likely the unrestricted 128PS version will turn up in bigger cars (perhaps it already has, but I don't think so). The i30 7 seater MPV could be a candidate I guess.

2. How is the restriction done, and is it possible to un-do it?

Almost certainly it's governed by the ECU map, and could be re-tuned like most CRDi diesels, just the results would likely be more impressive. This would be a declarable modification for insurance purposes, and would invalidate the warranty (if found). I know if I did this my insurance company would no longer insure me.

[Mike SX]

Thanks for the detailed information.

I am very happy with the car, and do not intend to modify it, once you start.......you never seem to want to stop.

I can remember dropping a Jaguar 'S' type engine into a Ford Anglia 105E, a few years ago, we called it a Jaglia, pulled away in 4th easily, broke the speedo first time we tried it, only on cross plys, with drum brakes all round, insured TP only, the shocked look as you overtook the "fast" cars of the day, as they tried to out-accelerate you, was obviously very memorable.
