Opel Insignia Country Tourer с Hi-tech 4 × 4
Torque vectoring with perfect torque distribution to each of the rear wheels
The ground is frozen and the steam from your breath freezes in an instant. Snow as far as the eye can see. The perfect conditions to get behind the wheel and take a few really quick tours in frosty Austria. If you want to have fun on snow and ice, you only need one thing: the Opel Insignia Country Tourer with Twinster four-wheel drive system with torque vectoring technology. This is an ideal partner in the snowy conditions of Tomatal, where Opel winter training takes place. The program includes not only braking and accelerating, opening the grip limits or masterfully safe driving in extreme conditions, but also provides a lot of fun. This is possible thanks to Opel's flagship, the Insignia, which in its version of the Insignia Country Tourer sets new standards in terms of dynamics and comfort.
With an additional 25 millimeters in ground clearance and protective body trim, the Opel Insignia Country Tourer awakens the desire to leave the smooth asphalt roads and provokes you to look for rough tracks. The secret of the incredible driving pleasure lies beneath the surface and is called the "Twinster four-wheel drive system with torque vectoring technology". "Extremely high levels of lateral and longitudinal stability, even in extreme road conditions, are characteristic of Opel's state-of-the-art dual-transmission system," said Andreas Hall, Development Director, Control and Drive Systems. on the four wheels of Opel.
High-tech 4 × 4 system for safe driving at any time
The innovative four-wheel drive system is based on a high-tech solution - in the Twinster system with torque vectoring technology, two sets of clutches replace the conventional rear axle differential. They allow torque to be applied in different proportions to each of the wheels with a change response within a fraction of a second, ”explains Hall. This means that power is optimally distributed at all times. "Twinster allows a wide range of torque distribution differences ranging from 0 Nm to one wheel to 1500 Nm to the other. In addition, we can change the torque distribution regardless of wheel slippage or speed. To all this is added the compact design: the presence of two sets of clutches on the inside of the drive shafts allows the complete elimination of the rear axle differential. This saves volume and weight, ”he explains.
This technology allows the Insignia Country Tourer to be more precise and dynamic when cornering, to have better longitudinal stability and to provide exceptional traction on any surface - even snow and ice. In principle, higher torque is directed to the outer cornering rear wheel, thus stabilizing the car; The Insignia writes corners with greater precision and responds more spontaneously to driver commands. Therefore, torque vectoring technology also leads to increased safety.
Opel Winter Training participants can experience all this first hand. For this purpose, they can temporarily switch off the torque vectoring system, which in turn is connected to the ESP system. "The comparison between the two regimes shows dramatic differences. If everything has been under control so far, without this technical support your piloting will end at the second cone, ”notes Hall. This is a driving in border mode, which no one normally wants to happen to him.
For comfortable drivers and sports drivers with serious experience
To all this is added the mechatronic chassis FlexRide, which is the basis of optimal handling, adapting to any situation. It changes the characteristics of the shock absorbers, the algorithm of the connection between the accelerator pedal and the engine and the moments for shifting gears (for cars with automatic transmissions) depending on the activated Tour and Sport mode, which are selected by the driver. Depending on the selected mode, the steering response to the steering wheel and engine response to the accelerator pedal commands becomes softer or more direct, and the ESP is activated sooner or later.
Those looking for a sportier ESP tuning and dual transmission can choose "Sport" mode. In this mode, the system allows a stronger rotation of the car around the vertical axis (ie a lower degree of rotation compensation, respectively skidding), while maintaining the dynamic nature of the Insignia Country Tourer. Those who prefer a comfortable and comfortable trip can activate the "Tour" mode with a button. The software of the central control system Drive Mode Control is the heart and soul of the adaptive running gear. It continuously analyzes the information provided by the sensors and settings and recognizes the individual driving style.
