Well i work for hyundai and i know for a fact that in 2009 they are making a RWD turbo 4 cylinder Tiburon, and it will be released in the states at the end of next year. I talked to tech line and they said they've been testing one without the de-tune for the street/emissions, and they say its been dynoing 400 at the wheels and moderate boost, and still averaging over 25 mpg.

These things will get eaten up...especially with the 10/100,000 warranty, so i'm sure nissan, toyota, and all the other big companies will want to make some competition for them.
