It's on their web site although I don't have the link handy right now. Bottom line is that they said the G37 is a capable car, but competes with the 335i only because of the price advantage. One unpleasant surprise to me was that the G37 is 200lbs heavier than the G35, and the performance numbers suffer accordingly do despite the G37 having 26hp more, it's 0-60 time is the same or even 0.1 secs slower than the G35 sedan... I have the full link:

but the article in print is different, so I'm not sure when they will up that article up online.
