Though there have been several different engines with varying power levels, the zero to 60 mph and ¼ mile times have actually stayed relatively consistent. Nearly every model will make 60 mph within 4.9-5.8 seconds and hit the ¼ mile in 13.5-14.2 seconds at 94-100 mph. Surprisingly, the earlier model years were actually a little quicker than the newer models, mainly due to abusive clutch dumps during 5,500 RPM launches. The clutches on newer WRXs are much lighter and harder to do high RPM launches from, hence the slower times.
