It does suck, those times seam pretty far off from what other mags have got, especially the 1/4 mile time. Heck my Mini Cooper JCW will do 0-to-60 in 5.7 seconds, the quarter mile in 14.3 seconds at 96.3 mph and the Z is way faster
Maybe you should write them a letter and ask why their test drivers suck at shifting and driving.
