170103M - Land Cruiser full release /41 Land Cruiser’s proven permanent four-wheel drive system uses a Torsen limited slip differential in the centre differential. The LSD uses low viscosity oil to reduce friction and support vehicle fuel efficiency. The unit has a motorised transfer shift actuator for easier High-Low gear ratio shifting and the shift effort itself has been reduced by 30 per cent, giving better performance in cold weather. In normal conditions, torque is split 40:60 front to rear, but the LSD can automatically vary the ratio from 50:50 to approximately 30:70 in order to achieve the optimum distribution in any given driving scenario. The four-wheel drive system also has a new rear differential, designed for greater reliability and strength with a 34 per cent increase in torque capacity. An additional rear diff lock is fitted to Invincible models, increasing stability especially in extreme off-road conditions.
