Full-time AWD Torque on Demand, which was rear wheel biased. That was unique. Second, external expansion chamber shocks. Third, dual mode transmission linked with the first two advancements. It had 4High and 4Low modes. The total package was functionally revolutionary. Hang onto yours, they will be worth something as automotive firsts someday, soon.
