Introduced a little over a month ago, the all-new Insignia Grand Sport will be able to put up a good fight against the 4Motion-equipped VW Passat thanks to its all-wheel-drive setup. Opel’s engineers wanted make the new midsize car as light as possible, so rather than installing a differential, the Insignia will feature a GKN-developed Twinster AWD arrangement with a rear drive module encompassing a twin clutch system.
It will be clever enough to independently send torque to one or both the rear wheels, depending on the situation. Case in point, torque vectoring will kick in to send the higher torque to the outside rear wheel when cornering, which according to Opel will enable sharper and more responsive handling.
In addition, the folks from Rüsselsheim are saying the implementation of torque vectoring will make the Insignia Grand Sport safer. How? Torque distribution will be controlled (aka yaw damping) at all times based not only on the road surface, but also on the steering angle and throttle position. This clever tech will pay dividends in terms of stability by granting the car with a more neutral behavior, thus making it easier to control by the driver.
Speaking of the person behind the wheel of the new Insignia, he or she will have the possibility to select the Tour driving mode for high yaw damping or the Sport mode enabling a sportier behavior, obviously.
Opel will have the Insignia Grand Sport on sale early this year and will show it in Geneva in March. The wagon version is scheduled to be unveiled later in the year, although there’s not much of a mystery concerning the Sports Tourer as it has already been spied in OPC Line guise without any sort of camouflage. A rugged Country Tourer is expected to join the family at some point, and hopefully there’s going to be a new sporty OPC variant as well.

Torque Vectoring All-Wheel Drive for New Opel Insignia
- New Insignia 4x4 offers optimum dynamics, feel and handling in all situations
- New Insignia’s all-wheel drive system delivers best traction on all road surfaces
- Torque vectoring applies drive to one or both rear wheels independently
Rüsselsheim. Midsize cars offering an especially engaging driving experience are mostly found at premium brands, but when the all-new Opel Insignia Grand Sport hits the market in early 2017, enthusiastic drivers will need to adjust their orientation
The new Insignia will be available with a state-of-the-art torque vectoring all-wheel drive system that delivers the highest levels of dynamics, feel and handling on the market.
“The new generation Opel Insignia sets new benchmarks for midsize automobiles” says William F. Bertagni, Vice President Vehicle Engineering Europe. “Torque vectoring represents the state-of-the-art in transmitting power to the road. The new Insignia with torque vectoring all-wheel drive matches the best in the industry when it comes to ‘fun-to-drive’.”
All-wheel drive and torque vectoring is the best way to put high power onto the road – be it wet, dry, icy or covered in snow.
But the additional weight and complexity of conventional torque vectoring systems prevent them from meeting Opel’s high standards for performance and efficiency.
The new Opel Insignia therefore utilizes a Twinster all-wheel drive system with a rear drive module that uses a twin clutch system without differential.
The Insignia’s all-wheel drive system can apply torque to one or both of the rear wheels independently, enabling torque vectoring capability across the car’s full performance range.
When cornering, higher torque is sent to the outside rear wheel, inducing rotation around the vertical axis (yaw) – the Insignia turns in with more precision, responding more spontaneously to inputs from the driver.
Torque vectoring also contributes to safety by controlling the distribution of torque according to changes in throttle position, steering angle and road surface, thus damping the amount of yaw. This intelligent use of torque distribution – also known as “yaw damping” – results in neutral vehicle behaviour, making the car more stable and steerable for the driver.
New Insignia drivers can choose the amount of yaw damping to suit their driving style by selecting the appropriate driving mode: from high yaw damping in “Tour” to low in “Sport”, for sportier vehicle behavior.
