The newest of new details came out this weekend about the 2015 ATS-V, I think you will be quite pleased. Propulsion is expected from a 3.2L Twin Turbo V6, which is contrary to initial reports that the ATS-V would simply borrow the CTS-V's larger 3.6 TT. Speculation from GM authority has Cadillac using the 3.2 instead of the 3.6 to beef up the engine to handle the stress of.... 500 HP!!!

Yes 500 HP, could the use of the 3.2 simply be about thicker cylinder walls? Whatever the reason, if the ATS-V does indeed show up to the party with 500 ponies on tap that is 70 more than expected from the new BMW M3

Happy Hunting...
