don't get me wrong but for the brand new state of the art F10 M5 to edge out a 4 year old CTSv competitor by such a narrow margin I am a bit disappointed. I foresee the revised CTSv to even it back up and then some. And even if the F10 can be modified in the near future or they up the boost somewhat, this current CTSV with $3-5k of mods is at 625 hp with a stock cam and heads. And with heads and cam over 700 hp easily. so bmw has their work cut out for them. For the $ i'd buy a low mileage caddy and dump in some mods and have $ left over for a nice E46 M3.
My fav videos of the 700 hp CTSv.
