New Kia Optima GT is powered by Theta II 2.0 GDI turbo, please do your homework first before comment anything

The spec you given for Cerato 2.0 is wrong, actually this is pre-facelift spec, the facelift cerato 2.0 spec is

152ps@6200 rpm
192Nm@4000 rpm

which is same as Hyundai Elantra 2.0


The engine code you mentioned for Kia Optima GT in other thread also wrong, it is 2.0 Theta TGDI instead of 2.0 Nu TGDI, FYI Hyundai never develop turbo engine for Nu engine family

Please do your homework first before making any flame here, thank you

New Optima GT launched and priced at rm179k powered by Nu 2.0L turbocharged boosted to 3.5L strength. Reminds me of when Mondeo 2.0T launched at Rm180k and eventually failed. What were they thinking? Most D segments sold are 2.0L at rm140-150k. Probably don't know how to compete head on with Japanese D segment so brought in turbocharged 2.0L hoping to gain some sales competing with Japanese 2.4L and 2.5L D segments. FC result in America, the FC of 2.0T Optima/Sonata are higher than 2.4L NA Optima & Sonata. What do the people here think? Looks like they think themselves as conti car selling at cbu conti price now. Chain reaction, the sales volume also become like conti in the past. Conti today instead playing by the rule going CKD competing with Japanese at Japanese price range.

Excuse me, I am not a Korean fans, I am a car engine enthusiast

I just want to prove that you know nothing about hyundai engine development history even though you did own 2 korean car before.

Hyundai develop Nu engine is to replace the Theta NA engine in 1800cc to 2000cc engine range, I highlight again, to replace NA engine.
the recently engine recall issue happened in US involved 2.0 GDI and 2.4 GDI Theta II engine manufactured at Alabama, US
the caused is the metal debris left at cylinder block during manufacturing process and it will hurt the conrod bearing in the long run

I would agree that most of the car salesman in malaysia is lack of technical knowledge especially on engine, this apply on every brand not only Korean brand

just some extra info to share about Kia Optima GT

The 2.0 Theta TGDI use in Kia Optima GT is the 2nd version of Theta TGDI as compare with 1st version use in 2011(YF) Hyundai Sonata in oversea market,
Some improvement over the 1st version :-
- Electromechanical VVT (intake side) to replace the hydraulic operate VVT (similar system with Toyota 8AR-FTS turbo engine and Mazda Skyactiv engine)
- Improvement on Engine refinement
- Improvement on electronic wastegate
- Improvement on direct injector
- Engine tuning

if any thing need to add on that I missed then please correct me and share with us, thank you

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

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.
