Details have emerged on the torque-vectoring all-wheel-drive system to feature in the all-new European-sourced 2018 Holden Commodore.

The Commodore will be a re-badged version of the Opel Insignia five-door hatchback and wagon, another General Motor’s subsidiary, Vauxhall, also offers the same Insignia.

Vauxhall has now released some information on the upcoming high-tech, all-paw traction set-up which will be fitted to its Insignia Grand Sport model.

Vauxhall says while the traction advantages of torque-vectoring systems are clear, until now they have been too heavy and too complex.

So GM has gone for a rear drive module which replaces the conventional differential with a twin-clutch system that can deliver torque to one or both rear wheels independently.

Torque distribution is adjusted based on changes in throttle position, steering angle and road surface, and the car’s amount of rotation around the vertical axis (known as yaw - so torque vectoring is also known as ‘yaw damping’).

Inside is a driver-select system for the amount of yaw damping - low in the Sport setting and high in the more relaxed Tour setting (using the Vauxhall terminology).

With more torque being applied to the outside rear wheel, turn-in is sharper and gives the feeling of more rear-end bias (so what is essentially a front-drive car delivers handling responses more akin to a rear-drive vehicle).

Vauxhall also confirmed the all-new Insignia will drive through an eight-speed automatic transmission.

Australian delivered Commodores will team the new all-wheel drive system with a naturally aspirated 3.6 litre V6 engine producing 230kW of power and 370Nm of torque, with front-wheel drive versions also available powered by turbocharged 2.0 litre petrol and diesel engines.

Production of the current rear-wheel drive Commodore range is set to come to a close on the 20th of October, 2017, taking with it Holden's V8 sport sedan range. However, the company has promised a sporty V8 offering will arrive to take its place, though not until 2020.
