Replying to: backy (Aug 27, 2009 5:48 pm) Would you take Wikipedia's word for it ? You already said a hyundai engine and you are spot on but there is a curve to hit. Global Engine Manufacturing Alliance is a joint between Dodge,Kia,and Hyundai to make the 2.4 engine that is used in your Kia and as I said before many Dodge products. Don't take my word for it just go to Wikipedia and if you want the facts type in{ World engine } and read the story about Global engine Alliance and notice that the 2.4 Kia,Hyundai,and Dodge engine are the same. Now who has done Homework ? Please know who you are taking too. Cars are my life and it is my job to know what is what. Not trying to knock Kia but you were lying and saying you could beat a Toyota camry with your new Kia Optima 2.4. Things are cheaper for a reason rather it be for the best or in most cases the worst. Stay happy and do more homework. Replies to this message: backy (Sep 16, 2009 5:42 am) mickeyrom (Sep 16, 2009 6:48 am)

Replying to: bob912 (Sep 16, 2009 4:14 am) ...notice that the 2.4 Kia,Hyundai,and Dodge engine are the same   No, they are not. I have done my homework on this, sir.   Under the new joint venture, Hyundai will have the lead responsibility for implementing the decisions of the joint venture company for design, development and engineering. http://media.mitsubishi-motors.com/pressrelease/e/corporate/detail156.html   The initial design of the engine block was handled by Hyundai. It features siamesed bores, meaning that there is no coolant flow between cylinders. The aluminum block has cast iron cylinder liners, and different liners can be fitted to alter the engine's bore. ... Each manufacturer has configured their variants of the basic GEMA design differently based on their engineering needs and standards, so consumers may experience very different power, fuel efficiency, and "feel" from each manufacturer. http://en.wikipedia.org/wiki/Global_Engine_Manufacturing_Alliance   Chrysler Corporation began production of a modified version of Theta, dubbed World Engine, in Dundee, Michigan in October 2005. Chrysler engineered their own air intake system and exhaust manifold which is made of gray cast iron. The World Engine also differs in the EMS as it measures the amount of intake air indirectly using a MAP sensor, to lower production costs. Contrary to what Chrysler Corporation has stated, the Theta engine factory in Asan, South Korea is not a part of the Global Engine Manufacturing Alliance. Construction of the Korean factory began in August 2003 and it came on line in April 2004. It is owned and operated by Hyundai Motor Company. http://en.wikipedia.org/wiki/Hyundai_Theta_engine   And the latest is, Chrysler has pulled out of GEMA and will be using the Michigan plant to produce Fiat-design engines as well: http://www.bloomberg.com/apps/news?pid=20601101&sid=aErSuN9aY8UE   So, hopefully it is clear to you now that:   * The Kia 2.4 is NOT a Dodge engine redesigned by Korea, as you stated. It is in fact a Hyundai engine, designed by Hyundai, with some common components including the block co-designed by Hyundai, Chrysler, and Mitsubishi with Hyundai in the lead.   * The Theta II engine used in the Optima (and other Hyundai/Kia vehicles) is NOT the same as the 2.4L Chrysler/Dodge engine, as you stated, although they share some components.   Also, I don't own an Optima and never said anything about the relative performance of the Camry and Optima.   So, stay happy and do your homework. Since cars are your life and it's your job to know what is what with cars, you should be more careful about your research. Also, a bit of advice: if you are going to tell someone he is wrong and is a liar, you should be REALLY sure of your facts. Replies to this message: mickeyrom (Sep 16, 2009 6:48 am)

Replying to: backy (Sep 16, 2009 5:42 am) Thank you for clearing up that for me.I read that the Chrysler I4 is not as refined as other 4s,yet the KIA and Hyundai 4 cyl engines are praised as being "refined".So,which is it? Obviously they are not the same.
