Car reviews - Subaru - Impreza - WRX STi sedan
22 May 2002
THE larger intercooler on the MY02 STi is equipped with a manually operated water spray - it operates in two-second bursts - that provides additional cooling under high engine load or high ambient temperatures. The STi also comes equipped with front and rear "Suretrac" torque sensing limited slip differentials, which respond to a torque differential between left and right wheels and transfer the torque from the slip wheel to the non-slip wheel. However, they only activate under drive and do not respond to differences in left and right wheel cornering speed when coasting. The front LSD is a new addition to the STi's spec sheet and has the effect of noticeably reducing understeer during hard cornering under engine power.
Did you know?The STi has a larger R180 rear differential, compared to the R160 of the standard Impreza WRX
