Our last Petrol vs. Diesel Comparo featuring the sassy Skoda Octavia drew the scoreboard at one-all. Now the pressure is on and the final round’s contender has a tough job to sway the argument one way or the other.

The final comparo for this season features Hyundai’s brilliant i30 hatch, and though we’ve been impressed with the i30 before, the results of this little experiment blew us away.

First up the sporty looking Vivid Blue SR went in to bat for its petrol brethren offering a 2.0 litre four cylinder petrol CVVT (Constantly Variable Valve Timing) engine not uncommon in spec to that found in the majority of small hatches.

On paper the synopsis is quite typical of an engine this size and the claimed economy figures do seem relative to the category, but just how these figures relate to real world driving can often be misleading.

How a car delivers its available power can be all together another thing to what seems true on the spec sheets. Body weight, throttle response, gear ratios, valve timing, electronic aids and chassis set up can all impact the way in which power is delivered, and the personality of this delivery can vary greatly in cars with near identical specifications.

Whilst 105kW @ 6,000rpm is a respectable output for an engine this size, the revs build in a far too linear fashion meaning the peak power delivery is never really felt and you’ll eventually find yourself on the rev limiter without having really achieved very much, almost as if the valve timing or cam lift needs revision.



It’s fine around town and it leaves a lot of its competitors looking like they’ve had one too many cheeseburgers, but out on the open road, especially through hills and windy bits, you just never really seem to be able to use all that the engine could offer, no thanks to a rather short torque curve.

The 186Nm on offer comes in soon enough for good pull from the lights, but fades off sharply after 4,600rpm creating a gap before the power peaks. In turn this leaves an exposed and weak high end which is further hurt by a gearbox ratioed to deliver fuel economy and little else.

First and second gear are quite tall and pull you from a standstill well, even with four people on board I had no trouble, but the all important pulling power expected from third gear just isn’t there and the loss of momentum at this crucial juncture is irretrievable.

The gap from second to third gear ratio simply does not match the overlap in torque/power delivery meaning a huge loss of power delivery at speed which can make highway overtaking very lethargic.



Final fuel economy figures came in a little over our expectations. ADR tests claim 7.2 litres / 100km combined average which was by our reckoning a little optimistic. Our results, 8.6.

Now don’t get us wrong, the petrol i30 is a good little car, and in comparison to similar hatches it’s brilliant, but it could be so much better but for a few minor alterations in gearbox ratio and/or CVVT settings. If you’re not after a spirited drive and are happy to go with the flow, this little beasty may just suit your needs.

However if you’d prefer a little more pep, and a lot more economy, then get a load of this. Forget everything you’d thought of small capacity diesels, the i30 CRDi is revolutionary in its ability and almost unbelievable in terms of power delivery and economy gains.


Hyundai i30 SX CRDi in Shine Red

It’s a rather quiet and smooth diesel, and most people won’t believe it is in fact diesel until you show them. Using modern common rail technology and a sweet little turbo charger, the 1.6 litre twin cam engine is surprisingly quick to rev, incredibly strong in terms of torque and amazingly efficient.

Presenting 85kW @ 4,000 revs and a very tidy 255Nm from just 1,900 rpm, the little oiler builds power very quickly and holds its torque over a nice thick band to offer incredible pulling power in all manner of driving circumstances. City gridlock, country cruising, freeway fastlanes, and windy alpine roads, it seems no challenge is to great for the i30 diesel’s stamina.


The gearbox is well matched to the power on offer and provides a flexible spread of gear ratios for any situation. Although the (gearbox) linkage feel could have been a tad smoother, it is nonetheless very easy to shuffle through from cog to cog with a nicely weighted clutch helping the CRDi feel that it will pull in just about any gear all day long.

Now for the best bit, the fuel economy. After my week with the car I managed an average of 4.7 litres / 100kms, which funnily enough is bang on that quoted by ADR tests (how often does that happen). On the open road lowering this figure is an easy task whilst around town trying to persuade the car to drink more than 6 litres was nigh on impossible.


Clearly then, the third round of our little comparo is awarded to the diesel vehicle. Not only has it proved a strong performer with its athletic performance but the economy figures just cannot be argued with.

If you’re the market for a new car, and the model you’re interested in offers a diesel option, then by all means drive both. You’ll be stunned at what a modern diesel can offer and no doubt further pleased with economy gains achieved.

Scoreboard – Diesel 2 : Petrol 1


  • milbob

    On the Hyundai Website, it states the Automatic Diesel consumes 6.0L/100km.

    So IMO, the Auto version isn’t worth as much now as it is only 1.6L/100km within the SR Auto.. with diesel being a good 30c difference today!

  • Matt

    Apologies for that one Milbob, you are in fact correct. The i30 CRDi Auto does indeed use 6.0 litres/100km (combined).

  • Lightbulb

    Even though diesel is dearer than petrol (that could change at any time) I agree with the review that the diesel version would be a better buy than the petrol model, not only because it seems to be easier to drive but also is more economical.

    Cheers !

  • http://realcars realcars

    Shame the petrol engine isn’t sorted.
    Couldn’t be too hard to fix?

    Shame about the domestic price differential between fuels.

  • milbob

    No worries Matt, I was hoping for a second that they did something to the transmission for better fuel economy!

    If the price difference wasn’t that much I would gladly take the plunge and spend slightly more for a better engine and environment. But 30c is way too much to ask.

    You’d have to travel at least 15000km/year to get the same amount spent on petrol! Even more if you want to recuperate the extra $2.5k for the diesel engine.

  • Carl

    Good to see a car company with the honesty to claim real world achievable fuel consumption numbers! (Toyota take note!)

  • Snowman

    Well, I’ve had my i30 diesel for a month now, and am very happy with it – worst fuel economy so far is 5.41 l/100km!

    This tank is going to be very close to the 1000km mark at current usage – and the price difference for fuel is only 20 cents here in Country Victoria, and I have done 3000km in a month so I’ll make the cost back quicker than a lot of people :)

    Quibbles?? Drivers seat could go back further on its rails, and a sixth gear for highway runs would be perfect – it would use a lot less fuel than it does now!

  • Tony

    The 1.6 Diesel is a very nice car but can you tell me how you calculated your fuel consumption. I hope it wasn’t with a pen and notepad. The hyundai website says the car you tested doesn’t have a trip computer.
    Secondly, why would Hyundai sell a car such as this, which will attract people who are trying to save fuel, (amonst others) and not include a trip computer which would cost about $10 to install?

  • Matt

    It’s not rocket science Tony. Fill the tank, zero the odometre, then drive around the city until it’s empty. Lather rinse repeat on country roads. The tank capacity is known, the distance traveled is also known. From there it’s very simple mathematics.

  • Reckless1

    Working out whether to buy the diesel or the petrol should include such factors as

    1) Price of diesel vs petrol – at the moment there is a hefty difference, but that is only because the oil coys are under scrutiny for petrol price gouging. They are not under scrutiny for diesel price gouging, so they are gouging. Expect the price to even out over the life of the car.

    2)Purchase price of petrol vs diesel – often the diesel is dearer, but not always.

    3)Driving satisfaction – clearly in this comparison, the petrol sucks, the diesel shines.

    4)Service costs – what are the service costs for a 100,000k set of services. This comparo can often be alarming. For this comparo, you have to keep it “factory” serviced for 5 years to preserve warranty, not just 3 like most others.

  • Andy

    Test drove it and its actually pretty good in Auto form. Now if only Kia gets that hot C’eed here (never thought i’d ever say that). Hav a look in Kia’s UK site and you’d be shocked thats actually a Kia/Hyundai.

  • trackdaze

    Even with Diesel at 30cents (were im at its 18cents)more it still makes economic cents!?

    Correct me if im wrong but isnt the diesel the cheaper in this instance?

    Remember, a diesel will get closer to its ADR fuel numbers than a petrol. This was borne out in the test. In auto form the petrol will do heaps worse than its ADR.

    At 4.7litres per hundred & 21k it trounces a PriArse.

  • Jonathan

    I’ve had my i30 CRDi for over 3 months now and I absolutely love it :) I bought it not for any sort of financial reason, but purely for performance reasons; the torque rush is awesome!

    This car does 40-100kmh quicker in 3rd gear than my Honda Civic 2.0 Sport does in 1st and 2nd gears. Acceleration is just so effortless; the car never feels like it’s labouring, it just digs deep into its bucket of torque and delivers. What’s more, it’s a helluva lot quieter than the Civic’s petrol engine… good to have a car that doesn’t scream all about it when you need to get on it.

    Best economy I’ve managed on 1 tank is 840km, in stop/start peak hour traffic along a very hilly route with the aircon. I can’t remember if I filled up last week or the week before.

  • Al

    I drove the SLX CRDi when it first came out and I was very impressed with its driveability over the petrol model. I wasn’t impressed when I saw the final onroad price for the SLX CRDi! They weren’t even prepared to do a deal as it was a new model.

    For about $3000 more, I ended up getting an 08 Mazda 3 MZR-CD turbo diesel that trumps this car on power and torque at 360 nm, and it even has stability and traction control as standard. Mazda even gave me $1000 of free diesel which will last me about a year.

  • Carl

    Al….that Mazda 3 diesel must be a cracking car to drive with all that torque! What sort of fuel consumption are you getting?

  • booter

    isnt hyuandai the group that were flogging their fuel economy results after the last solar (and others) car race. only to be noted that they didnt adhere to the normal conditions driving policy of the race. had only one person in car, no air con, no windows down and a support car to carry the drivers luggage?? from what i could find on the web at the time, all other cars had a driver and passenger, their luggage and air con on (driving through centre of OZ youd want it). i remember seeing a photo of the driver pushing his huyandai into the service station. if you want diesel fuel economy get a peugeot, they are the best with diesels, i borrowed a friends and drove from sydney to mt hotham and back to wodonga before refueling

  • Cameron

    A slick looking car. Nice work Hyundai. Even if its styling is borrowed from BMW.
    Reported 0-100 in 11+ seconds for the diesel undoubtedly is because most turbo diesels suffer off the mark. Turbo lag is a killer and the only way to get around it is a bi-turbo config which is costly to design and build. If you want to be quick off the mark this car isn’t for you. If that’s not you major concern but you appreciate in-gear acceleration then you will love this donk. Particularly when you want to overtake, it will leave the 2.0 petrol looking lethargic.
    Could be a fantastic little car for towing a small boat or trailer too. And considering some guy has driven from Adelaide to Sydney on a tank its damn frugal on the open road. If fact he had enough juice left over to continue up to Newcastle before it was spent!

  • Tony M

    What seems to stand out here is that the petrol engine needs to rev up to it’s optimum torque figure of 186Nm which drops off dramatically after 4000rpm and the diesel doesnt need to rev as hard as it reaches its torque figure of 255Nm at 1900rpm. I believe that the petrol engine is working harder than the diesel which is a lazier engine. Longer term wise I believe the diesel is the better option.
    One thing that never seems to be considered is the expected period of time that Mr and Mrs average keep their cars. I know that I normally keep our family car for 5 to 10 years which goes well for a diesel purchase. But I think if you were to buy a new car every 40,000km/2 years it might be better to purchase the petrol option.

  • joober

    Agree, its all about what you plan for this car, if only keeping for a year or 2. But then again diesels are probably more wanted than petrol variants so you probably get more on the resale…

    Diesel should be cheaper than petrol, given that it doesnt need to go through the full refining process. But as petrol its tied in with barrel prices. So diesel is a temporary measure.

  • Blue

    If you haven’t driven one of these little CRDi gems, do your self a favour… go test drive one… I drove one back to back with a Focus Diesel and a Mondeo Diesel. In terms of the engine… No Contest. This little thing will knock your socks off.

  • No Name

    Ha Ha all the diesel critics – AND THE DIESEL DOES IT AGAIN.
    $5K extra for the gutless poorly tuned fuel guzzling petrol.
    TP eat your heart out dude. One day you\’ll realise common sense as well as common rail is the thing old chum. 😉

  • Myke

    Question: Why does the petrol only get a space-saver spare type while the diesel gets a full-size?

  • Dazz

    Hey Johnathon..Checkout http://www.i30Ownersclub dot com

    I drove the Mazda 3 Diesel and the i30 Diesel back to back and went with the i30 (brilliant)

    From my understanding the SR model usually comes with full size 15″ steel wheel. Most buyers of the SLX Diesel have been lucky enough to get 5 alloys (even though supposed to only get 15″ steel spare!)

    Great Cars.. pity about the waiting list…



  • Al

    I have driven my Mazda 3 turbo diesel 3700 km now and I have averaged 7.3 l/100km. This has been mainly city driving in Brisbane. When I drive on the highway it drops to about 6.0l/100km because of the sixth gear it sits at 1800 rpm at 110 kmph!

  • Carl

    Al… haven’t even run it in yet, those numbers will come down further in the next few thousand Ks!

  • Technofreak

    The CD engine is the perfect engine for small cars. Better economy and performance than any petrol engine could ever hope….and soooo much fun to drive :)

    I bought the larger Mazda6 MZR-CD…..holy crap does it haul! tries to rip the tyres off the rims!….hehehe

  • Chris

    Just to add to the argument, my wife & I purchased a new Renault Laguna Diesel & we are totally impressed with it, sure its a wee bit louder at idle, but once on the move its very quiet. And with less than a 1000k’s on it now its returning 7.6 L/100 & will only improve with running in.


  • No Name

    I have an elderly Pug 406 2.0HDI which does 7.4 round town in commuter stop start. and 5.2’s on motorway work at 120Kmh. Not actuallt too bad for a bigger 9yr old car with 170K k’s on the odo.

  • http://evo Frugal One


    DIEsel, +30cpl and rising….


    Buy the ULP and SAVE!



  • himi

    Great comparisson test guys! I love how the blue i30 SR looks. Compared to cee’d it’s a little better car (more comfortable)…but both, cee’d and i30, mean the new beginning for Hyundai-KIA.

  • asdf

    With the diesel being so good on the open road, why on earth would hyundai leave cruise control out of the slx when it is part of the standard features of the petrol version, this was the deal breaker for me, just not interested in a vehicle withour cruise (use it every day)

  • Al

    >>>> I bought the larger Mazda6 MZR-CD…..holy crap does it haul!

    It’s the same engine in my smaller Mazda3 hatch.

  • Name1

    Why is there a difference in turning circles of the petrol and diesel i30?

    The i30 does seem a great car, I haven’t hear much, if any, problems about this car at all, all reports seem to suggest it’s great. I’ve seen one pass me in a carpark, and I couldn’t hear the engine idling at all – it’s silent!!

    Shame the price of Diesel is more than Petrol, but there’s still the benefits of a Diesel motor – torque at low revs, etc.

    It’ll be a good buy on the second hand market, I’m sure!

  • Al

    >>>>> Shame the price of Diesel is more than Petrol

    I’m yet to see a Diesel engine cheaper than the Petrol in the same model.

  • Fred

    Curiously, I’ve only seen two i30s on the road since I came to know about it months ago. Is it selling well at all?

  • JansJetta

    To put another foot in, I went for the VW Jetta. Up to the 15000klm service, I have averaged 6.2l/100 90% city driving(best 5.2 on a run from Perth to Bridgetown – 697klm). It’s a 2.0l 103 killawasp and 320nm engine. Luv the torque.
    Paying up to $1.80 per litre but again – do the sums when comparing Diesel to ULP. It costs me less than 10c per klm.

  • Al

    >>>> To put another foot in, I went for the VW Jetta.

    But they don’t even make a VW Jetta hatch, so it’s not fair comparing it to the i30. Plus it’s a lot more expensive and the tail lights look weird (sorta like a 1980’s Sigma).

  • JansJetta

    Fair call Al, I was commenting on what I decided to buy when looking for a diesel and how it was going. If you want a diesel hatch to compare to the i30, then look at the Golf (the world standard for hatches) or the Polo, which won the best small car in Australia for the past 2 years ….and that is even more economical (in the 4s) than the diesel Jetta.

  • paul

    I too test drove both the i30crdislx and mazda3 diesel back to back, i bought the mazda for several reasons,it has far superior handling and performance, a six speed box standard dsc and traction control, and the most important reason, hyundai dealers tried to flog me an 07 model at full retail(touch over 30k)with hardly any discount, mazda dealer on the other hand,offered me 07 model more than three grand cheaper than the hyundai, enough said!

  • bikejockey


    I was concerned about the service costs for the diesel – got the salesman to list all services for both petrol and diesel up to 120,000 km.

    Diesel was 10% cheaper.

  • Chicka

    Looks like everyone is happy with their diesels… too.
    I purchased a Ford Focus TDCI 2LTR @ $25990.00 driveaway,and couldn’t be happier.Just love the 320nm torque,and getting
    great economy.With mixed Town/Highway driving I am achieving the quoted figures of 5.6ltrs/100kms.Seriously looking at a performance upgrade with a tuning chip to take it to 120kw and 380nm…still doing research on the varying units available.Maybe someone has a turbo fitted with a tuning chip
    and could offer some advice on which brand they chose and why?

  • Caspah

    Could I please ask where did you get the Ford Focus TDCI 2LTR @ $25990.00 driveaway?
    It would be worth my while traveling anywhere to get it for that price.

  • Chicka

    Gooday Caspah….Yep, I am happy to tell you that I purchased my Focus TDCI from the Pacific Ford Motor Group at
    Maroochydore on Queensland’s Sunshine Coast.After researching the vehicle on the Internet,I noted that these guys had great deals happening on the TDCI….I found that they had plenty of stock, and offered great deals.I flew down from Cairns( where I live)and drove the vehicle back over a 2 day period.
    Here are the contact details…
    Ph 07 5458 9713
    Fax 07 5458 9799
    I dealt with Robert Atkinson( Sales) and Mike Jackson(Finance)…..
    At the time ( April 2008), they explained that sales of the TDCI were slower than expected because of people wanting an “automatic” version of the vehicle.., and currently, only the manual 6 speed version was available.
    Well, as far as I am concerned…That’s great!
    I loved the car from the first moment I drove it….
    Hopefully.. You will have the same experience…
    I have about 4000 kms up now and I love it more everytime I drive it!
    PS.. Although I stand to gain nothing from these comments.
    My dealing with Pacific Motor Group …..Exceptional!
    Everything was easy as…
    Wonderful People….Highly Recommended…
    All the very best!

  • Chicka

    Hey Casper…more info for you…I see that Pacific Ford at
    Maroochydore are now offering the TDCI at $ 24.990.00 Drive Away.What a bargain !

  • Glen

    If a large number of Australian and American motorists started driving cars that burn less than 6L/100km of fuel, the demand for oil would fall and the price would fall too.
    The i30 CRDi shows that a family with up to 4 adults can do this.

  • Glen

    The good thing about small diesels is they can tow a trailer or a small caravan. My 2L 307 HDi uses 7.5L/100km with an AVan Aliner in tow. A Corolla uses nearly the same amount with no van and you can’t tow anything with a Hybrid Prius.

  • http://evo Frugal One

    GLEN –

    A Corolla using 15l/100km, i don’t [know] think so.

    The Corolla is the BEST HATCH from ASIA, decades ahead of Korean product.



  • Phil

    We’ve had our i30 SLX for about 3000ks so far and don’t regret it. Very comfortable to drive and no vices. I commute between 2 country towns in W.A. (Denmark and Albany, around 53 kms apart) daily and average 5.1 per 100 kms with the lightest possible throttle on mostly flat roads at a tad over 100 km/h. Power/torque is smooth and usable across all driving conditions. Conventional wisdom suggests that the really good consumption figures won’t be available until at least 10,000 ks. I can’t wait – already, I’m getting nearly 1100 ks from a tank, but you do have to be patient when filling it owing to the frothing nature of diesel.

  • Garry

    Phil Is that the manual or auto?? What did you choose and why thinking about trading my Tucson in on a i30 TD.I like auto over manual with other TD’s a 5/6 speed auto is available.Hyundai have only put a 4 speed auto in the i30 and TD Sonata.Or would a manual be better???

  • Glen

    Frugal One, the Corolla uses 7.3L/100 with no van, my car uses 7.5L/100 with a van in tow.

  • Phil

    Garry, we chose the manual primarily for reasons of economy. After all, the i30 was chosen for that reason. As a postscript to my comments – I have tried driving progressively slower in fifth until I can achieve mid 3s at around 70 km/h, which is pretty special. However, the reason that I don’t do so regularly is that I can’t see the sense in doing that speed on the open road – there does have to be a trade-off between superb economy and getting to your destination before you die of old age. I’ll keep averaging around 100 kmh until the price of petrol suggests that I start going slower.

  • Mick

    I have just brought the I30 SLX Diesel, and have noticed that the distance to empty component of the trip computor is not working correctly, it seems to be going down 1 km for every 2km that i do. Hyundai service say they have not seen the fault before, has anyone else ?

  • http://realcars realcars

    Mick does this rate of consumption occur on cold short runs or long highway trips or both as computed consumption will be significantly higher on small runs while the engine is still cold etc.

  • Russ

    We purchased an i30 SX diesel last week. I test drove lots of cars prior to the purchase including a Corolla which I could only describe as being very average. As soon as we drove the i30 we both knew that this was the car for us. I can’t believe how good this car is for the price we paid. We’re loving it!

  • Do test drive all brands before buy

    Some of Korean car is much better than Japanese and European car in terms of quality and price. I had test drive Toyota Hiace diesel and then Hyundai iload diesel ysterday ..Toyota Hiace diesel? Absolutely rubbish compared to Hyundai iload

  • phil

    Just something to watch for with the SLX i30 manual if you have after market cruise control fitted: autopilot is definitely designed for automatics! If you have it switched on and knock it out of gear going downhill it will disengage OK, but DON’T FORGET to engage fifth again before re-engaging autopilot or you’ll get to see what 6 grand looks and sounds like in angel gear. Or so I am told.

  • Tony Dawson

    I have done 18,000kms in my Hyundai i30 1.6 ltr diesel manual. Mostly country touring. This car has very few niggles. If I was a city driver I would buy the auto- the manual would be annoying there. The manual is good but would be even better of a 6th gear was added. Challengers like Focus and Astra manuals get similar economy figures because they have a 6th gear. Economy? – well cant complain BUT average cruising at speed limits gives 5.3-5.7 ltrs/100kms. City driving 5.9. If you drive slow and light footed even 3.8 is possible but unrealistic. It is achieved under turbo revs – under 2,000 in every gear. The motor eats hills, feels robust, cheap to service, inside is comfortable, easy to use and reach audio controls. I tow a 600kgm caravan with it and does it easily. Well done Hyundai.!!


    You guys with the i30 diesels have got to be *burning*..

    Diesel is now 35c/l MORE than ULP, and here is the crusher, the i30 petrol is already very economical.

    You will NEVER make up the extra $2500 extra to buy the diesel in the first place, and now the actual $/km is about equal.

    Enjoy the greasy filthy concrete and fuel-hose and nozzle at the servo-station.

    One day you guys will discover the real discount fuel, its made in australia and goes by the name LPG




    Your graph/data above is WRONG as in a error listed.

    The auto diesel use 6L/100km and NOT 4.9L/100km.

    Its very close to the 7.6L/100km that the ULP uses, so you can see the auto is hardly much more frugal than the diesel [overpriced] model.

    The above confirms what i said on the above post

  • Mel

    I’m currently awaiting delivery of my brand new i30 SLX manual diesel. It was supposed to be put on a truck this morning for transport to me 1200km north of Perth. The lady from the dealership in Perth called me earlier to say she had taken the car for a run this morning, and found that there was something wrong with the gearbox. She took it to the workshop where it was found that a tooth was missing from one of the cogs in the gearbox, and they will have to put a new gearbox in. I’m hoping I haven’t bought a lemon since I live 450km from the nearest Hyundai dealer.

  • Boney Maroney

    I filled up this morning…..surprise surprise, deisel now is te same price as ULP………whos burning now, when I get 4.9 to the 100ks, I am saving money every k i travel, and will make up the initial purchase price difference in 18 months, and from there baby it is savings

  • Ian

    I understand the extra tax on diesel fuel is because it pollutes the environment more than petrol. The pollution from petrol is reduced because of the catalytic converter whereas the diesel exhaust is full of poisonous heavy metals. I certainly HATE to follow diesel vehicles because they stink. The “rotten egg gas” from the petrol vehicle smells like roses in comparison. The petrol Mitsubishi Colt gets equally low consumption figures (as the i30 diesel), and you don’t have to worry about the price difference (fuel and purchase costs), or the pollution.

    • Robin Graves

      Where the hell did you get that chestnut from? Heavy Metal in Diesel? I think you might be mistaken for a ’80s ‘rock’ band.

  • JollyRoger

    @IAN^ Well said!!

    Smallish petrol powered vehicles, like even the i30 are already very frugal on fuel, the difference between them is very small.

    NO real world savings to be had with a DIEsel

    • Ozman

      I guess that you have never driven or compared a petrol 4 to a turbo diesel. Economy is only a small part of the equation. The torque in the I30 diesel is massive, there is just no comparison between a 2 litre petrol engine and the I30 diesel. My wife has one and I drive a 6 litre Clubsport. I find the I30 a really fun drive because of the torque. The gearing is really tall and 65K in fifth gear isn’t possible but once you hit 70K you can leave it in fifth all day and pull up hills that would have most cars going back two gears. Put four adults in the car and the passengers will ask what you have under the bonnet. The I30 is the best bang for your buck in its class and and then some.

      Jolly did you not see the end of test figures you moron? the Diesel got 4.7 litres per 100 and the petrol got 7.2 per 100, that’s a huge difference. 53% higher and looking back at Frugals stupid post about Diesel being 15 cents a litre dearer at the time, it was still more economical. Most I paid at the price hike last year was 1.88 a litre of Diesel. Now based on the difference unleaded would have to be cheaper than 1.20 a litre to be the better vaue fuel. Well let’s see, 1.88 minus 15 cents equals 1.73.

      Nope even at the height of petrol and Diesel prices in 2008 Petrol was still 53 cents a litre worse off.

    Does anyone know why some diesel cars in this country have particulate filters and others not? Does the i30 have one? From my readings they are very expensive to replace if they fail.

      I believe the Manual i30 does not have a DPF while the Auto does.

        Both manual and auto have a particulate filter. Be careful which oil you use, it must be made for vehicles fitted with the particulate filter. Supercheap Auto have a Nulon variety which complies and is recommended for the I30 diesel.

    Petrol SUVS and Falcons and Bommodores, Magnas, Aurion etc etc etc emit far more CO2 than diesels.

    Get over your ill informed prejudices and try a diesel.

    In the UK cars the Rego is not based on how many cylinders a car has but rather on how much CO2 it emits.

    You would pay a fortune to drive the inefficient and uninspiring hunks of junk littering the roads over here.

    Because fuel is cheap here (compared with Europe) the car makers are buyers are lazy and the net result is polution and lots of it.

    As a driving instructor, I use my SLX 2.0 petrol I30 and is a great car.
    It’s true that the petrol version is designed for economy and not racing, so is a bit sluggish, but other than that is sweet.
    If this car will last me 5 years and that means about 300 000kms, then it must be a good car.
    Holden astra can go and screw itself from every point of view.

    Funny how people convinced that LPG is a better solution. Unless i drive a bus or a truck its not even a consideration. The i30 Diesel is a real convincing alternative. Its a bargain at whichever way you look at it. For under $30k I don’t know whats the argument is. Compare to a Peugeot, VW diesel varient the Hyundai is a small change. Extra torque, extra economy, quality and real world price tag its a winner.

    I got one in Brazil 2.0 aut. with sunroof for usd$38k(american dollars) car are expensive here you know but I like this car.
    Mine is a 2011 model, 1600km driven and does 7.87km/l on average, I just drive around the city and push hard the gas pedal sometimes too. Girls can’t stop looking at it. xD hahaha at least here it has a lot of status.

    The Hyundai diesel has no particle filter which means it will/does spew soot into the air we breathe; these are not city cars !

    Hate dirty diesels,
