haha, dont misunderstand, so far i am 110% satisfied wif my EF. However, the 6 speed gearbox is a major concerned since it's new. I still remember the defection of Honda Citiy 7-speed gearbox few years back, which cost 20k++ to replace a new one.
for engine wise, i thought theta 2 is a new since previously is theta 1 ? the HP and Torque produced by theta2 is very exciting and the FC for the new YF is the main reason i choose YF.
Oh ya, dont forget the interior design, which is totally a step ahead of previous style. Damn, i love it !
It is way too early to tell if the new Hyundai 6-speed gearbox is reliable but I'm betting that it is. Hyundai is using the same gearbox across most of their range and it would be disastrous if it is not reliable.
Theta I and II are the same engine, just that Theta II is an improvement of Theta I. There is also a Theta II engine with GDI direct-injection technology but it appears that won't be offered in Malaysia.
