Superb ride comfort, driving dynamics, and steering response, with reduced noise and vibrations are the main benefits gained from the Opel GTC chassis. The high torsional stiffness of the Opel 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 ensures high stability in curves, the long wheelbase a smooth ride even on bumpy roads.
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 Opel GTC – proven with the award-winning Opel Insignia OPC – 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 maximized, resulting in significantly overall ride and handling.
The rear suspension of the Opel 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 racecars. In effect the principle is straightforward.
A steel crossmember just behind the wheel centerline carries the two struts of the linkage. These are pivoted in the middle and the ends attached to the lower wheel carriers. The major benefit of this compact system effectively prevents any lateral movement of the axle, providing more stability, a smoother ride and improved handling.
Imagine a car that continuously adapts its behavior to road conditions and your driving style. That, at the push of a button you can select a comfortable cruiser or a dynamic sports car. This is exactly what the FlexRide system is all about.
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. 4-channel 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 3 operating modes ‘Sport’, ‘Tour’ and ‘Normal’ – all of them optimized for different driving scenarios from taut sporting excitement to relaxed long-distance cruising with uncompromised safety and stability.
