Well if your going to post the "best" 0-60 time posted by a magazine. We should at least compare it to the "best" time posted by the E92 M3.
In that case... the
E92 M3 runs a 4.1 0-60 compared to the 4.7 of the 370z. As you can see this is CONSIDERABLY faster. So no... a 370Z can't keep up with an M3, or an IS-F for that matter.
And I agree with RCZ. 3/10ths is a lot when you are looking at cars in the 4 second range. It becomes exponentially harder to shave tenths the faster you get.
That said, 4.7 is a great time and I'm proud of the Z.
