its not good to compare 0-60 time from different mags, or even the same mag. testing conditions will vary from track to track. the driver also makes a big difference. the best way to compare is to wait for compairision article, when the cars are test by the same drivers at the same time.
also, alot of the time, the test cars arent broken in yet. 1/4 mile can drop as much as .3s after break in.
