A perfect platform
Superb ride comfort, driving dynamics, and steering response, with reduced noise and vibrations are all benefits of the Astra GTC chassis. The high-torsion stiffness of the Astra GTC body ensures optimum preconditions. The advanced suspension provides excellent handling precision, ride comfort and extremely low levels of noise and vibration. The broad stance of the car ensures high stability in curves, and the long wheelbase a smooth ride even on bumpy roads.

HiPerStrut front suspension
Using a powerful engine in conjunction with conventional McPherson strut front-wheel-drive systems causes problems, the most obvious being torque steer and radical camber change. The HiPerStrut front suspension of the Astra GTC overcomes these and other disadvantages. By decoupling the steering from the wheel motion geometry, torque steer is reduced to almost zero and traction under heavy acceleration is maximised, resulting in significantly overall ride and handling.

Watt’s link rear suspension
The rear suspension of the Astra GTC is a compound crank axle with Watt’s linkage. While the principle of Watt’s linkage has been known for over 200 years, more recently it has been used mostly in racing cars. A steel cross-member 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. This compact system effectively prevents any lateral movement of the axle, providing more stability, a smoother ride and improved handling.

FlexRide chassis
Imagine a car that continuously adapts its behaviour to road conditions and your driving style; a car which, at the push of a button, allows you to select a comfortable cruiser or a dynamic sports car. The FlexRide electronic chassis control system reacts instantly to changing conditions and continuously adapts to your driving style. Continuous damping control adjusts the damper settings in real time. Four-channel anti-lock braking system (ABS) with electronic brake-force distribution, traction control, and ESP Plus all work together to provide fantastic driving dynamics. With the FlexRide switches, you can change the entire driving dynamics at the touch of a button. Choose between the three operating modes ‘Sport’, ‘Tour’ and ‘Normal’ – all of them optimised for different driving scenarios from taut sporting excitement to relaxed long-distance cruising with uncompromised safety and stability.
