As per advise before, no need to reply to this thread
Let it idle n move to page 2 so no one will bother
There's specific optima thread in car clubs where he's not welcome there
U can contribute there

Maybe goldfries can move this thread to /k since it's not helping to optima buyer at all

What's the big deal that Kia uses the Theta engine instead of the Nu engine for the Optima GT? It just means that they haven't developed turbo for the Nu engine, that's all. Do you think that such a big corporation like Kia can't maintain 2 separate engines? What confusion for the technicians? Every auto company have a variety of engines and they have no problem on spare parts and training for all of them. You talk as if Kia will collapse under the weight of maintaining both the Theta and Nu engines. Even Proton has lots of different engines and Proton is a fraction of Kia's size.

The problem with you is that you tend to blow things out of proportions to fit your blinkered view that Korean cars are dying without you and your friends' help. You can talk till the cows come home but Kia and Hyundai are doing very well without your help. Your vision of doom and gloom is just to satisfy your biased mind but it isn't going to happen. Korean cars continue to improve every year and they are almost on par with the Japs. Give them a few more years and they will overtake the Japs. Korean cars no longer compete on being cheaper, they compete on quality and value for money now.

If you think Korean cars are dying then so be it. It's enough that you convince yourself, there is no need to try and convince others. There's so much prejudice and hatred in you towards Korean cars that you can't be a good judge of their future.

As you said, walk in customer care about the car it self, not much about the specification details. Then why so much talk about specification la, power numbers la, torque ratings la, engine family la....etc

It is their engines, and they will decide what engine characteristics suite what particular model. Multiple engine families can give headache to technicians/mechanics??!! oh wow 

Before you discuss about the korean engine family "confusion", please make known to your members how to deal with this first ar :

later he say you infringe his freedom of speech rights 

Oh wow....implying it yourself then pusing your words....seriously great "respect" 

Putting on the hat of a "commentator", using the impassioned image of standing on the great ideologies for open/transparent discussion and freedom of speech, bemoaning on the declining quality of comments, with approaching 40 years of "industry experience", seeing unfettered lies....got to clap hands dude   

And just few years ago, you're the same person who points out all the good points that you now turn it to bad points...

With the great irony in preference to commenting in absolutes, not willing to consider some context, subtext and pretext of a given matter, people give another side of the view or requesting clarification or refuting you, but anything contrary to your views, confirm kena label as die hard korean fans or employees working for hyundai/kia. ....just wow....

No harm to point out issues, but your unreasonable amplification and constant unnecessary alarmist tone, that is something to reflect about. Certain subjects are not as simple binary like the CPU/GPU example you gave to the moderator. For CPU/GPU, the points to consider are just a handful, the max performance, performance per value, and to some degree, cooling performance and form factor considering the sizeable demand for HTPC. Nothing much subjective other than some people preferring how bling bling the LEDs are. But coming to cars, got so much more to factor in as people have different personal preference for any given price point, but you make it seems so binary.

Optima GT turbocharger is outsourced ??? When did manufacturing of Kia Optima GT outsource to 3rd party ? Mind to share with us what is the company name ?
If what you mean is the turbo turbine then I can answer yes, FYI, most of the car manufacturing in the world do not make their own turbo turbine, BMW, VG, Audi, MB, Honda, Toyota do not make turbo turbine.

I advise you to do some homework on Hyundai engine before giving any nonsense comment, please check the objective of development of nu engine and Theta engine respectively.
A lot of enhancement(not only engine tuning) has been done on Theta engine use in Kia Optima GT as compare with the 1st version of Theta use in 2010, At least I would say Hyundai is honest, they did not play around with engine code name even though they can change it to new code name, technically it can qualify as a new engine. Take the current Honda engine 2.4 EarthDream as example, Initially I though it is a new engine when it launched 3 years ago, but I found out it just a gimmick, this engine is almost the same as K24 engine which was developed at 2002, Honda just did some enhancement on existing K24 engine and market it as EarthDream engine, what's wrong with Hyundai did the same thing and keep using the old code name,  what say you ?     

It is not an issue if you share with us the serious flaws, but the problem is you are keeping to tell us the flaw with some point is not make sense and obviously you are bias and not from the neutral point of view.

I still remember you are the one who put a lot of flame in Autoworld/Nissan forum in many years ago, at that time you commented Nissan car is not worth a single sen, this round is Korean car, so what is next ? Honda ? Toyota ?

and Last I would like to update you, Most parts in Nu GDI is identical with Nu MPI engine

So the reason for this hatred is because your friend failed to be employed by kia/hyundai Malaysia?

Wah..since when become chassis, thermodynamics and physics engineer? Even experienced auto news journalist don't simply make such claims but you 

How much more rougher?

How much less inefficient?

How much more incapable ar?? 

What are the metrics you used ar??

Be very careful of what you want to say, because what you commented on the engine alliance is falsehood, the other way round was true. It was hyundai that came out with the general blueprint for the engine block and headers. And it was then Chysler (now FCA group) that decided to end the joint venture and buy out both mitsubishi and hyundai's stake.

I think the friend thingey is a facade of saying that they didn't hire him. But regardless, he will sway like the wind wherever the wind blows. He/his strategist friends are just lucky opportunists that managed to hop to Honda at the right opportune time.

So much ego to claim the global and regional team's effort as their very own.
Can go higher, but pay more for higher rated tyres, strengthened internal components and enhanced suspension to handle that additional speed.

Did I say Nu MPI and Nu GDI is 100% identical ??? What I trying to say is most of the parts is identical, don't try to tell me both type of engine use different engine oil filter and air filter...

Based on the parts number I got from stockist, the short block, throttle body, VVT mechanism, oil pump, water pump, MAF, O2, EGR valve, PCV and many other parts is all identical, the diff parts is fuel injector, fuel pump, cylinder head, spark plug and of course the ECU.

Top Car manufacturer in 2016 (Based on the total number of cars sold in the world)

2.Toyota
3. Renault/Nissan
4. Hyundai/Kia
7. Honda
10. Suzuki

The ranking is telling the truth

I 100% agree that Malaysia authorized Korean car distributor need to improve their marketing strategy and after sales service, they still left behind from the Japanese brand competitors, nevertheless we able to see the improvement over these few years  but this is not enough to change the old school perception from the public.

I think the so called ACE Strategist is himself la. Rejected by Korean Company, so now spreading all the hate here.
Nobody in their right mind would hire such employee. 
Last time Kind Strategist, now Ace Strategist. Next will be Hyper Ultra Mou dak Deng Strategist.

K Thx Bye before he come and flame me 

currently have any pre-reg unit for optima GT ? or any 1 that bought this car?

Please share, on what is volvo's strategy to overcome their poor resale value.

And please share on how is volvo's great strategy will affect japanese car sales..

What is the advantage of buying a volvo also need permission?

Imaging a family trip with ferrying 4-5 persons in a v40 on a 4 hours journey ,
maybe shorter time, bcos T5, vroom vroooom !!!! Ignoring of aes too !!!
And small luggages behind the tiny boot.
Really ?????

V40 is tiny. I would prefer Optima GT... but then RM180k for Kia/Hyundai brand... 

... might just end up with Camry Hybrid. lol

wow...really a sign of desperation for using a car of different segment and market segmentation to make the comparison and making things up without proper reasoning. I can't believe that an industry "giant" with approaching 40 years of experience together with so many industry "insider" can make such a write up.

Aiyo why can anger them? It is actually good for their development as you "challenge" them to up their game constantly. Kaizen right, continuous improvement, your gang working in Honda should be very familiar with this culture and should actually thank you.

Are you so sure that it is more technologically advanced against the koreans version of the 8 speeder? No industry experts say that but you can?
Why don't you also state the annoying points of the korean gearbox? I stated it before sometime ago, why don't you use my word against me? Oh i know why, because your mazda also have part of the similar annoying point regarding the gearbox, don't want to spoil own market?

I really thought you would use more points, but just only that gearbox thing? Why don't state the obvious also :
- faster acceleration
- class leading safety features
- conti feel, etc

Why don't you also state the not so obvious :
- the V40 is actually a shared platform with the ford focus, with interchangeable suspension components. Since you say Ford here is shitty strategy and parts damn rare, do you think that volvo malaysia with even lesser sales volume and service centres will have a better situation?
- the facelift is late by almost 2 years and it will be "obsolete" in less than 2 years as the replacement is just on the near horizon
- it uses belt driven timing
- the turning radius is larger than average
- you really think the maintenance costs actually cheaper??

Come on la...You only think just because of the Volvo belonging to China, the parts will be cheaper. Please enlighten us which tier 1 major parts suppliers that are not manufacturing in China? They only supply to Volvo exclusively in your mind? Did you even read the automotive news before commenting? Volvo is going to have electrification on all of their products before 2020, you think that more hybrid parts will be cheaper to replace and maintain? You keep bemoaning there are no electrical experts in malaysia, and you think by going exclusively doing all maintenance work in the official service centre throughout the lifetime of car ownership is going to be easy on the pocket? Oh wait....the hybrid battery pack is from LG wor.... and how much is it going to cost to replace electric driven air cond compressor ar??

And you really have a hard time really understanding what is model facelift do you? All brands does that on the average of 3.5 years, even your dear Honda does that. Die die want to say sonata new horizon as new model when it is actually facelift.

Car talk, yup, with more and more misinformation and misrepresentation of facts.

Looks like you getting more sloppy to even try fact checking, Volvo didn't say they are fully phasing out internal combustion, nor did i mention it. But it is a fact that they are not keen in diesel anymore :

http://autoweek.com/article/diesel/volvo-s...-demise-horizon

They will only have hybrid/battery electric propulsion for all models in the turn of the decade :

https://www.nytimes.com/2017/07/05/business...ectric-car.html

And the environmental treaty is called the Paris Agreement :

https://ec.europa.eu/clima/policies/interna...ations/paris_en

So, using your very own nomenclature, despite both the koreans being top 5 in the world in terms of car volume, you still insist in claiming that parts damn rare, owner will suffer till die...

http://www.infographicsarchive.com/economi...les-statistics/
Despite Volvo being owned by Chinese, how much more they sell around the world, malaysia's volume is almost like a rounding adjustment in the company as a whole, and you actually expect can have more parts here? And, if you really pay just a little more attention, the approach that Volvo will be embarking is approaching what range rover is doing, going even more upmarket. With more and more hybrid parts and batteries that come from "be-hated" Korea instead of China, you really think maintenance and ownership cost will be cheaper and easier?

You really like out of context comparison, how old is the genesis range in the market and how old is the 5 series or volvo s series? Genesis range only come into market around 2008-2009, less than 10 years to date. Nevermind, this one how hard they try, still many years to go to have even a little more brand presence.

Eh, you were so good last time to be able to pin point steering rack no smooth to machining residue from manufacturing? Still don't know what am I trying to hint you? It is a hardware nuisance, not the mere subjective juddering of the matrix; and best of all, I'm referring to the 6 speed box, how come you can go to matrix old box? That point is such a good point for your propaganda against the korean brand, even i won't refute you a single bit on that.

Haih...sonata new rise argument again, still cannot accept that it is facelift :
http://www.caradvice.com.au/530970/2017-hy...ealed-in-korea/

You should be more aware then me right? When marketing, must hype as much as possible, but why hyundai so "humble" to claim it is just a more aggressive facelift? Won't it create even more hype by "lying" to the world to say this is a new generation model? Let me tell a real product that like your words, a short lifecycle like a handphone --> Honda Civic FB

Year in production : Jan'11 to Sept'15 (4 years 8 months)

Fitting on facelifted parts to the non facelifted version is not the determining factor whether it is actually a facelift or not. Some cars yes, but more and more of them not. Don't believe me, since you have so many insider contact, please go try fitting in the facelifted mazda3 GVC LED headlights into your very own non facelifted version. Associated electronic components aside, try physically fitting it in just the headlight assembly.

yupe, continue yawning under your own ego....

I can come out with links to refute your points because i read it before, i don't even need to try so hard to trawl google. I know you don't believe all these, and likely that you don't even care to read what was in it. It's all right, because it is for other readers to be wary of your misrepresentation of facts by your comments.

Volvo made the statement loud and clear :
- hybrid and electric lineups at the end of the decade
- they will no longer put in resources to develop new diesel engine

And this is the 3rd time i'm repeating it, they didn't say they are giving up internal combustion engines. If yes, how is it still a hybrid?

What you see on the road is not what i'm seeing, as the 2 unit of v40 i saw were the time with ford engines and transmissions. Anyway, there is no way of verifying either of our observation on this.

Outside of home market, Genesis was a car mainly catered for the US taste, Malaysia is the odd one out in the asia region selling this. In their main target market, they are picking up speed :

http://www.thetruthaboutcars.com/2017/06/h...al-predecessor/

If you want to use this argument, why honda legend isn't here? I read about it 2 years back and sounds like a car overbuilt, almost like vw phaeton. Damn taukeh type of car. Your gang should have super great ideas as it is equivalent to a 5 series/E class right?

Here, i'm specifically addressing your comment on the "activation" of the turbocharger rpm range as what you say is misleading. Have you ever tried just using your fingers to flick the turbocharger's blade and see how easy it starts spinning? And that is still without the full pressure of oil lubricating it. Normal turbochargers at operation can spool more than 100,000rpm. How much more force would the car exhaust be generating even at idle. And it also seems like you have no understanding of reading the engine power/torque graph.

[attachmentid=8968693]

I'm using the 8AR-FTS power graph used in the NX and GS as an example. The torque curve is 1650-4000rpm. If really as per what you say that the turbocharger "activate" at 1650rpm, how come the torque curve is stuck flat around there till 4000rpm and after that drop ar??? Going by your thoughts, shouldn't the torque line shoot up sky high? Below 1650rpm, the turbocharger tutup valve and exhaust gas go straight to exhaust and not spooling the turbocharger??

Did i ever said that the mazda3/6/cx5 sold here are whole new generation/redesign? By your thoughts, the new generation CX5 is lie by mazda because it has so much similarities with the current one? I'm pointing out that interchangeability of exterior parts between facelift and non facelift model is no longer a determining factor to categorise the model whether facelifted or not. As i said, you own a mazda3, just got try physically fitting the facelifted GVC headlights into yours. Let the lights do the talking.

I'll also let this picture do the talking :
[attachmentid=8968754]

Mazda is going to lose out as they haven't gone turbo or hybrid. With turbo options from other marques buyers in Malaysia are not going to buy a Mazda 6 with puny 2.0L engine or 2.5L NA engine with high road tax but less power than smaller turbo engines. Even the Mazda 3 will suffer with no turbo option. Nissan is another loser selling dated cars. Kia and Hyundai are right there competing with the Japanese with turbo and hybrid engines like the Optima GT, 2018 Sonata, i30N, Elantra Sport and Ionic. Yet you keep knocking Korean cars but not a word about Mazda or Nissan. Very biased.

Snap me a photo of the exerpt you read about the turbocharger "valve". I'm fine to be corrected, but please may that valve not point to the blow over valve or wastegate...

Aiyo, why so much talk about torque test. I say about exhaust spooling turbocharger, you point towards torque test?? Apa la ni?? Likewise i can also ask, why you suddenly silent about honda legend, maybe you don't even know it existed?

How many diesel hybrids out there that are on sale?? Volvo and Peugeot did that, but both silently stuttered it. And because you have no context, pretext and subtext on the diesel issue, so you won't be able to understand why diesel will be more and more unwelcomed in the consumer driving. And you have no idea on what is the cost of maintenance for the diesel exhaust after market treatment components. Any engine block, regardless of diesel or petrol, if properly maintained and done at least 1 round of rebuild will not have issues going 20 years.

In the other thread, you referring to volvo powerpulse and mazda's (not honda la) dynamic pressure turbo is it? From what you written, i suspect whether do you even understand how it works??

No need paste photo here, i know how your car looks like. Please go have a good look at you headlight against the photo of the facelifted GVC headlight.
Because he own mazda, don't want to spoil own market. Maybe when he sells off his car or somehow someone in mazda fired his gang member, then all the negativity overflows; like what he does now against the korean counterpart.

Mazda is stubborn, want to pursue something a little oddball against the market trend. It makes sense also as their overall market share in the world is small fry compared to the peers. So instead of fighting in the red ocean and lose out in most of the criterias, might as well play in the blue ocean for the select number of people who just don't concur to the mass appeal of toyota/honda/nissan.

this is wow....

You're right that not all turbocharged cars need blow off valves, but those that don't use BOV must still employ some kind of diverter valve that serves the same purpose. BOV dump to atmosphere, diverter valve goes back into intake.

When wastegate operates, it means the boost already over the handling limit set in the ECU. That's why there is "waste" in wastegate, the turbine already turning so much earlier than that la....

And already told you, turbo "kick" refers to the reaching of optimal operating range of the turbocharger, also known as surge line. Depending on the model and application, the surge line will be different in line with the exhaust pressure of the applied engine rpm range. Before you hear turbo whine, the turbine is already spinning, and spinning faster than you think.

I know you won't accept that the turbine already spinning at engine idling rpm, because of your vast "insider" knowledge right? And because i'm google keyboard warrior that can't understand "jargon" right? Too bad that you have no way to prove me otherwise either because your facts are incorrect. Go ask your qualified mechanic friend Mr. How.

Anyway, this is for those that are curious :
