if i'm not mistaken the G35 will have a 3.5 liter engine. hence the name G (35) since nissan names their cars by displacement numbers hence 240sx (2.4 liters) older I30's (3.0 liters), 2k2 I35's (3.5 liters). and since its goin to be a 3.5 liter engine, i can safely assume that its goin to be the pathfinder/maxima/altima/I35's VQ35DE. plus its goin to be RWD!!!! this thing is goin to haul sooo much ASS. its goin to kill the IS300. actually the MAXIMA's already can do that
and its goin to give the bmw 3 series a run for their money, and might even beat them in performance. go NISSAN!
