There was a discussion earlier today (sorry, late yesterday) on whether the Sonata Embera would be launched in a CRDi Avtar, and that discussion moved on to Hyundai's CRDi range of Engines.

A bit or research showed that there's been quite a lot of development by Hyundai on the CRDi front. I collected stats from various places to bring together this (incomplete) listing of their known CRDis.

Note that this range does not include the 3-pot 1.5 litre CRDi currently used in the Accent here - that has been replaced by a new 4-pot 1.5 litre CRDi which is smoother and comes in two states of tune.

As mentioned in that thread, their new VGT series of CRDi engines seem to be taking these diesels into serious petrol performance territory.

The CRDi range:

Capacity Type Cylinders Max Power (bhp @ rpm) Max Torque (nm@start rpm)

1.5 CRDi 4 87 @ 4000 215@1900~

1.5 CRDi VGT 4 103 @ 4000 235@1900~

2.0 CRDi 4 110 @ 4000 235@1800~

2.0 CRDi VGT 4 125 @ 4000 285@1950~

2.2 CRDi VGT 4 152 @ 4000 35KGNM@2000~

2.5 CRDi 4 140 @ ???? 314@????

2.5 CRDi VGT 174 Bhp @ 3800 Torque - NA

2.9 CRDi 4 165 @ 3800 345@1750~

I amjust wondering whether Hyndai is going to upgrade their present CRDi offerings in India.
Especially the ones in their sedans.
With Fiesta Duratorq coming up, We seriously need to assess which one is real value for money. Yes, FE is the main reason in going for diesels but I need a greater torque too.

I am sure Ford's range will be more refiend and better overall than the crdi's of Hyundai.

Because all the other diesels in India when the crdi was launched came from the palaeolithic age, the Hyundai's seemed awesome etc etc. Not to say they are not good engines and all ( they most certainly are) but they arent superlative. Their refinement and NVH could certainly be better.

[Mpower]

Good Summary Steerioid. I haven't kept up with Hyundai's latest diesel offerings. Look like they havent fallen back in the technology race. The 1.5 VGT makes outrageous torque.

Hyundai's diesels come from Detroit Diesel and VM motori.

Sonata 2.0 Crdi was supposed to launch globally 4th quarter 05...still no news.

[drifter]

@Islero: Its mostly the 3-pot thats lacking in NVH...drive the Elantra CRDi and theres a world of difference. Its so much more quieter and so much more refined.

But have heard a lot of good things about that diesel in the fiesta as well...will have to try it out.

If I remember right, Hyundai has some tech-MOU with Merc and hence Hyundai have those great CRDi engine. Lets see what the VGT engines can do if brought to our roads, till then i am gonna wow and drool and dream driving my next car which can be the next gen Accent with that 103bhp CDRi

In between, can someone enlighten about VGT?

p.s. : just read Mpower's post, but still I think I read abt the merc link with Hyundai

[drifter]

Yup theres a link with merc...cant remember exactly how but it has something to do with detroit diesel producing the CRDi engines for hyundai and i think detroit diesel is owned by daimler. Could be wrong though...but there is certainly a link to mercedes...try and go through the first overdrive test of the CRDi.

DaimlerChrysler owns Detroit Diesel, who in turn makes engines for Hyundai. That's the link.

2.2 CRDi VGT 4 152 @ 4000 35KGNM@2000~

These specs are pretty similar to the Merc C 220 cdi.

1.5 CRDi VGT 4 103 @ 4000 235@1900~

Those are some serious numbers. 235nm from a 1.5? Amazing.

Used to. Hyundai makes their own CRDIs now, products of their Namyang R&D setup. The initial batch of CRDi engines were from Detroit Diesel (eg. the one that's on the Accent) but the later ones (eg Tucson/Elantra) are Namyang products.

The rumour is that it would get the same engine as the new Santa Fe that was launched on the 22nd of this month...the 2.2 litre VGT. Thats probably the reason for the delay as well...

Dont bet on it....refinement is the reason they changed the Accent's engine from the 3 pot Detroit Diesel to the 4 pot in-house CRDi. Unlike Ford's TDCi which is developed by Peuguot, Hyundai have moved away from 3rd party dependence.

VGT is Variable Geometry Turbocharging. I dont know much about it other than what I read up yesterday, but basically it means that an electronic vane controls the flow of exhaust gases to the Turbocharger...


You can read a bit about it here:

The strong commitment to diesel engines has played a significant role in Hyundais strategy to grow in the European diesel friendly markets, and others emerging (India etc.)

I doubt you will find much good in fiesta diesel after driving the crdi. The Indica blower can make the fiesta eat dust in a 0-100 drag, even more so if you make it 0-120. I doubt fiat getting close enough to hyundais performance in near future. All they have done is bring a moden spacious diesel car in the 6-7 bracket. The Hyundai was a generation older and the only competition for Ford. But if hyundai introduces the new 2006 version at the same price, it will spell trouble for Ford.

[Mpower]

Detroit Diesel bought VM Motori and DaimlerChrysler bought Detroit Diesel. Hence the link. The 2.4 petrol is also shared with Chrysler and Mitsubishi. Jeep Liberty diesel uses the Terracan lump.

Korean local market strongly favours diesel these days (surprise!) and hence Hyundai's been vigourusly developing their own diesels lately.

I think they are still in the process of launching these new VGT engines. Nothing is out yet except maybe the Santa Fe. maybe thats why Sonata crdi is getting delayed. Is the indian Tucson VGT?

VGT is a device that cuts lag and improves peak power. something like VTEC.

Yes, other than the Santa Fe the only other models to feature the VGT are the Matrix and the Getz (both get the 1.5) primarily in the German market. The Santa Fe VGT is also restricted to some European markets - the UK doesnt get the 2.2 VGT and will probably get the 2.5 CRDi.

I thought it was different, actually - it optimizes boost as opposed to valve timing. Could be wrong since I've only started reading up on these - apparently Bosch is developing VGT for John Deere's high-end super tractors...

[Shan2nu]

Is the indian Tucson VGT?

I don't think so. As far as i know, there are no VGT engines in India. I'm azuming that the VGT in question, is the same VGT that stands for "Variable Geometry Toroidal". Unless we're talking of "Variable Geometry Turbochargers".
