Just remember that there are multiple factors to bear in mind when comparing the relative speeds of two cars in terms of "my car is faster than yours". Weight, HP, and torque are your big 3 in a straight line.
To use your example:
stock nismo 370z 0-60: ~4.4 sec
quarter mile: 13 sec
stock hyundai genesis R-Spec: 0-60 ~4.7sec
quarter: 13.3
