I agree that Nissan is towards comfort, but the Teana rides and handling is much better then the Toyota Camry, as for the interior design, I quite like it, at least it is not as complicate as the Sonata and Optima, which given me a feeling of "too much" buttons that did not properly place. For Optima K5, actually I have tested it once even the showroom still di not have any test unit, honestly, I felt the interior design for Kia Optima is kinda outdated, just look back the 90s' Camry, it is quite identical if you see carefully the dashboard design. As for the rides and handling, I think you should test drive the Teana again and you will find the difference, people told me that the K5 handling like European cars, but I honestly tell you that I found the Teana rides and handling is the most close to the European cars, maybe it is because Nissan share the platform with Renault, and this Teana platform actually is designed by Renault. Just Nissan tune it to softer side for more comfortable, but not as soft as the Camry. The engine output on paper for K5 actually beaten the Teana hands down for the 2.0, but when you drive it in real world test, the result will be in opposite direction. So please do not bash me or what, I just write out what I have gathered so far for these D-segments vehicle, especially those new K5 owner. And now I'm eager to test the all new Camry and see what Toyota able to improve since it is using back the same platform, engine and gearbox for the 2.0 version.

Actually... Lexus (luxury vehicle division of Toyota) is boasting the world's first 8 speed AT, even the Toyota Camry sold in the US is having a 6-speed Electronically Controlled automatic overdrive Transmission with intelligence (ECT-i) and sequential shift mode (Compared to 4/5 Speed AT here), TEN airbags (compared to TWO here), navigation unit, plus all the bells and whistles that are in the KIAs and Hyundais and PUGs.

It's not that they don't have the in-house technology or are reserved as clearly seen in the examples above....

I say they are simply taking their market position HERE for granted... cause customers here would blindly purchase a Toyota even if it came with 3 wheels and a motorcycle engine.
