OUTLINE OF CONSTRUCTION
l Full-time 4-wheel drive, incorporating a viscous coupling is used on the BP DUHC Turbo model. BP SUHC
engine equipped models are fitted with an electronically controlled, lockable center differential.
With this system all driving conditions are easily contended with; from good roads to bad roads and
ad-
verse weather conditions.
l The transaxle and transfer unit were developed based on the GSM-R type transaxle.
The transaxle, center differential, viscous coupling, and front differentia! are a single, compact unit.
l The center differential employs a planetary carrier. system and a viscous coupling, and functions to distrib-
ute the driving force to the front and rear differentials as needed.
Through the use of this center differential, tire scuffing common to 4-wheel drive vehicles during tight cor-
nering, is eliminated.
l The speedometer driven gear (for detection of vehicle speed) is installed in the transfer carrier and detects
the speed of the rear wheels.
l Lubrication oil of the transaxle and transfer unit and of the carrier is contained separately.
