Integral Active Steering.
The Integral Active Steering for automobiles with rear-wheel drive combines passively steering rear wheels with variable steering ratio at the front axle.
At speeds of up to approx. 60 km/h the rear wheels turn in the opposite direction to the front wheels. This subjectively shortens the wheelbase, improving manoeuvrability and agility. At speeds of up to approx. 60 km/h the rear wheels turn in the same direction as the front wheels. This subjectively extends the wheelbase, increasing stability and comfort - especially when changing lane quickly and abruptly.
