The Grand Sport premieres Opel Insignia 4×4 traction vector torque split

All-wheel drive will debut the second generation of the Opel Insignia promises much more sporty, superlative traction and a significant reduction in consumption.

When in Spring 2007 start the commercialization of the second generation of the Opel Insignia, saloon that has helped the brand to position the beam at a higher step, will do a version with a special mechanical gadget. It’s about the all-wheel drive with torque vectoring sharing, which enables distribute torque motor so completely Independent between the rear wheels, It is even able to send all the power to one wheel. But not only depending on available traction at all times, but also specific programming chosen by the manufacturer for each driving mode; according to the traction, but also the throttle position, the angle of the steering wheel …

Thus, mode Tour his directional effect be less Meanwhile in Sport we will have the feeling of driving a car lot more agile, like in the tightest corners had a much shorter wheelbase of which actually has; while sending increased torque to the outer wheel to induce a greater rotation about its vertical axis. Without ignoring that precarious grip conditions may apply torque to the ground in the most efficient way possible.

He system, it provides GKN, It is called twinster. Technically it has a module at rear with a double clutch that allows you to do without differential. Thus, depending on the couple that decides to send to each wheel opens more or less each clutch. The rest of the system is equal to the previous Insignia 4×4, a differential multi-plate clutch as a link between the front and rear.

The great advantage of this system compared to others who also make a vector dynamic torque distribution is in addition to their greater flexibility, which enables dispense with assembly complex planetary gears on each side of the differential and save weight. Against which it used for stability control, do not It is a system restrictive, which selectively brakes each wheel to induce a greater or lesser rotation, with much less wasted energy. Even the clutches of the rear wheels allow a total disconnect. Not surprisingly, according GKN, the system is achieved twinster one fuel savings of between 0.3 / 0.4 l / 100 km compared to other AWD systems. At the moment, this system twinster in its different variants, also can be only drive cars also have a shaft or dual clutch as the union between the front and his backside also can be seen in the Ford Focus RS and Range Rover Evoque.

Yet They are not defined motorizations which will be available with all-wheel drive this, what we do know is that initially will be combined with exclusive automatic transmission torque converter speed ZF 8, although it is also studied to offer it with the manual gearbox.
