Yes it seems like the general public is still doing final testing for several automakers. IMO the jury is still out on DI. I'd rather take the hit for few HP and mpg and stick with FI. I don't need or want the hassle. Opinions vary.
I agree with you completely, I'm actually happy that we traded in the Optima with the 2.0T. They do seem to produce more power, but I would argue with better FE, at least in my experiences. Our 2.0T never got better than 30mpg highway and it was rated at 34. My MIL has a 2.4 DI Optima, which averaged 24.XX mpg while I had it for a week. Certainly some DI apps do achieve good FE, but I'll wait a while before I consider another DI vehicle.
