I've noticed that the korean automakers were ditching the larger engines and going with turbos to make up the slack. OF course, I was told that Hyundai was buying their V6s from Mitsubishi, so I can understand if they would rather not have to buy when they could build.
My experience with rental Optimas and Sonatas tells me that they don't have the acceleration with the turbo I4s as they did with the V6s. So personally I am not a fan of the trend. There is no replacement for displacement.
