Though with it making about 470 HP, I'm kinda sad it won't be going into the ATS-V. Unless the ATS-V's version of the TT 3.6 V6 makes significantly more than 420 HP, would rather have the LT1 in the ATS-V. Can't imagine the fuel economy being that much better with the TT 3.6 vs the LT1( since the LT1 uses about 12-18% less fuel than the LS3).
