At $550 a pop for the Continentals on the Golf Benough its in a slightly different league than an i20 (are they out yet? I think you mean i30) You dont buy an i30 if you want a sports car. With the extra $20k you save from a GTI thats a lot of fat tyres for your Hyundai! If Hyundai do bring out a sport hatch with these engines then you might have to upgrade the golf because it might have a little bit of trouble keeping up..

Sounds like the Koreans have gone shopping in the european parts bin.

Case in point, they obviously bought their ESP from them.

How’s an i20 round a corner?

I once had to keep up with a diesel i20 in my Golf GTI TDI but the tyres on it looked like they were from a pushbike.

It’s one thing to be equal but another to innovate

Yes we all know that bmw and VW have already been in similar territory.. but the big deal here is that it is HYUNDAI!!!!!!! dont you remember the first gen excel??????

Seems Hyundai have caught up with others. Reckless is quite correct about the tuned outputs and turbo charging. VW’s golf 8 yrs ago had diesel outputs (sorry for bhp outputs) of 115 and 130 and 150. Whilst the 150 was obviously quicker the 115 was the nicest to drive. Again BMW supplied 2.0litre units to Rover producing 116bhp whilst the same engine in a diesel I think had 125bhp but the rovers was a more refined installation.
It not all about max torque and power, its how its produced. Nuff Said

The other variable you guys are omitting is emmissions. thats the thing they need to balance to come to a compromise. This is not just a matter of bolting on a bigger turbo. Dont forget Hyundai have been making some of the most powerful diesel engines on the planet for some time – in the region of 100,000 HP in conjunction with Wartsila, in there ship building industry. Different kettle of fish but they aren’t mucking around!

The thing to remember here is the power output is directly controlled by the ECU, Injector system, and turbo size.

Hence it is no real feat of engineering to produce these power outputs, considering it uses the Bosch injectors, and more than likely the Bosch ECU.

The VAG 2.0T 125kw engine is conservatively fuelled (as would be the MB and others) for longevity.

A simple reflash of the VAG diesel (see superchips.co.uk) results in 146kw and 427nm, which easily surpasses the Hyundai output.

The other issue affecting real world driveability of any turbo, and particularly the diesel turbos, is how early the torque is available and how broad the torque band is. It’s childs play to up the turbo size and create massive numbers, but if there’s huge lag as a result the engine is a monster to drive in the suburbs.

So, accolades to the Koreans for building this engine (using Euro injection technology), but let’s not get carried away so we think they’ve beaten the Euros – they haven’t. I have driven the 2.5 Diesel Sorento from the same family, and it’s a ripper of an engine except for the severe noisiness of it before it’s up to operating temperature, and the turbo lag which was a pain even in the auto car.

Usually a balance between torque and power is to do mainly with the engine being understroked or overstroked i.e length of stroke relative to the bore.

Formula 1 like high performance bike engines are built to produce high horse power with relatively little torque at high RPM because it easier to produce high power as the more rpm the more power produced and these machines are relatively light so they don’t need large amounts of torque.

To produce both high horsepower and torque figures as this Hyundai diesel claims is definitely a product of design rather than just tuning.

Power figures are simply a matter of tuning. Formula One engines produce 550+Kw from 2.4 litres. ANY manufacturer could obtain the figures Hyundai has produced if they wanted to. The trick is to make an engine high in output while simultaneously FUEL EFFICIENT and DURABLE. Do people honestly think that Hyundai has suddenly out-engineered BMW from far left field?

Can’t wait to find a rolled or wrecked diesel Tucson, I’ll snap it up and shove the 2.0 diesel in a Getz….woooohoooo!!!

Thats a great effort by Hyundai, really taking off my hat to them.

Just hope that more power/torque does not equal more fuel used, beats the purpose of having a diesel.

Oh and Bosch did NOT invent common-rail, FIAT did
