...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.
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.
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.
And the latest is, Chrysler has pulled out of GEMA and will be using the Michigan plant to produce Fiat-design engines as well:
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.

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.

Interested in hearing about owners reactions to Turbo version miles per gallon. Hyundai Sonata Turbo's owners are reporting disappointing low mileage ratings. Insile Line is testing an SX Turbo and the best mileage it is reporting is below the city mileage rating...20 mpg.

I would also be interested in hearing real world mileage for the 2011 Optima. Turbo, non turbo and hybrid (when it's available).

Right now I'm sitting at low 20's in MPG, 22.1 I think. This is with only 500 miles on the car at this point. Mostly back road driving. The onboard MPG calculator seems a bit off to me so I'm trying to track it via fuelly.com now. We'll see.

Thanks dash5. I look forward to a later update.

I have a 2011 EX w/ Premium Package (Non-turbo). I'm getting about 28mpg right now. I'd say the mix is 40% highway, 40% suburban, 20% city. It only has 790 miles on it. When I was driving steady at 55mph and staying light in the throttle, the computer was showing about 39mpg.

Thanks for the info. Your %'s are about what I do. I think I would be pleased with that MPG. Are you? Have you been able to test MPG strictly on highway driving (a long trip)?

The longest trip I've taken it on so far is about 140 miles in one direction. The trip computer read 34.2 before I hit traffic (where it took 30 minutes to go 1.5 miles). I don't know the actual. I figure it was closer to 33 mpg. The route is very hilly. The lowest I've gotten has been 22 mpg (actual) on a tank where I did not have a single trip over 7 miles long. The car still has less than 2800 miles on it.
