Superb ride comfort, driving dynamics, and steering response, with reduced noise and vibrations are the main benefits gained from the Opel Astra chassis. The high torsional stiffness of the Opel Astra body provides optimum preconditions for excellent handling precision, ride comfort and extremely low levels of noise and vibration.
The broad stance ensures high stability in curves, the long wheelbase a smooth ride even on bumpy roads.
The unique rear suspension of the Opel Astra is Watt’s link in all models apart from the 1.6 Essentia which has compound crank.While the principle of Watt’s linkage has been known for over 200 years, more recently it has been used mostly in race cars. In effect the principle is straightforward.
A steel crossmember just behind the wheel centre line carries the two struts of the linkage. These are pivoted in the middle and the ends attached to the lower wheel carriers. The result is that any lateral impact on one side is immediately compensated by an equal amount of force on the other side, increasing stability. The major benefit of this compact system effectively prevents any lateral movement of the axle, providing a smoother ride and improved handling.
