The active stabilizer system relies on vehicle body sensors and electric motors.

The development of APSSS is claimed to be the world's first electric active stabilizer system.

Even the addition of Sperry active stabilizers failed to compensate for the inherent instability of the new design and in 1934 Ryūjō was taken in hand for extensive modification.

Along with the hybrid GS 450h and previous GS 430 models, the V8-powered GS 460 offered the Active Stabilizer Suspension System for improved handling.

Standard equipment on the LS hybrids includes all-wheel drive, a Torsen limited-slip differential, and an Adaptive Variable Air Suspension, plus an optional Active Stabilizer Suspension System (an upgrade to the standard multi-link front suspension expressly developed for the LS hybrids).
