The car is going to be badass compared to the current Z, 332hp/295tq, 400lbs lighter, 9 inches shorter. Being that the current 07-08 VQ35Hr Z's with 306hp can hit 12.9 bone stock, this new 370Z should be a total monster. Im assuming 12.5 should be no sweat in stock form.
Also the new HR platform trickles down from the GTR, the motor is able to handle boost now unlike the VQ's of the former Z33, Most HR Z's boosted are holding 500Hp @ 8lbs with not a single problem.
This new ERA of the Z platform is going to be the performance Era. Thats actually what the designers goals were. The car was made to compete with the Porche Cayman.
