Motortrend got 5.0 with the g37 7 speed sedan. I expect a bit faster with the 370z.
Not surprising, the acceleration times for the brawnier G37 S are markedly improved over the less-powerful, five-speed G35 S. Zero to 60 now takes only 5.0 sec, with the quarter-mile obliterated in just 13.5 at 105.3 mph. Compared with numbers from our long-term G35 S -- 5.3 and 13.9 at 99.9

Unless there's a launching issue (axle hop/traction), that is way high.
The same powertrain in a 300+ pound heavier G37 is getting low 5's to 5 flat...
Problem is... less weight over the rear tires for launch traction, both in total, and as a percentage ratio (47 vs. 46%).
A G37 has 47% of it's ~3600 pounds over the rear tires = 1692 pounds.
The 370Z has 46% of it's ~3300 pounds over the rear tires = 1518 pounds.
IF the Z can hook up, and put those 275 rear tires to work on the sport pkg... we're talking mid-high 4s...
(for comparison, the Cayman S has 55% of it's ~3000 pounds over the rear 265 tires = 1650 pounds)
It's all about off-the-line launch traction...

0-60 time although widely used is the most useless measure of a powerful 2WD vehicles performance. It's so dependent on driver and road conditions and happens so fast that it's very hard to compare 0-60 times of different vehicles with different drivers on different surfaces.
The numbers I'm waiting for are the 1/4 mile ET and TRAP.

For instance, when the WRX first came out, I think it was C&D got a 5.4 sprint to 60... hellafast for the time. But the quarter mile was 14.1 at 96 mph...
Pay attention to the quarter times... screw the 60. You're not even done with second gear...

What you are not putting in your calculations is total vehicle weight. It matters. The G37 has a lot more weight, therefore slowing the launch (acceleration). The amount of weight on the rear tires at launch is only off by 1%, which matters more than the actual number of lbs over the rear axle.
But still I agree. mid-high 4's.

Doubtful. The C6, which weighs about the same as the 370Z has 436 HP and 424 TQ/LBS and does 0-60 in 4.0 to 4.4, depending upon which road test you decide to believe. With over 100 HP less and over 150 less TQ/LBS, the Z will be lucky to break under 5.0, if even that.

It will break under 5. 4.7 or 4.8. If the 135i (+100 pounds) is doing 4.8, the Z will at least match that...

I was just saying that although pure weight loss helps, you also have to look at weight distribution, which is (relatively) poorer in the 370Z... although not by much.

Maybe, but BMW has always been pretty good about minimal drive train power loss. We can hope for the best, but I really don't see the Z being within much less than a second of the C6. Either way, a couple of tenths here or there are pretty meaningless when compared to the whole driving experience. I'm sure the Z will thrill.
