Along with its impressive powertrain features, Rainier's all-wheel-drive capability includes an on-demand system that enables owners to feel secure in a variety of driving conditions. Combined with its standard locking rear differential, this system is fully automatic and requires no input from the driver.

Rainier's powertrain performance is further enhanced with a sophisticated chassis control system combining excellent passing and towing attributes with driving characteristics comparable to a luxury sports sedan.
