Polestar may now be a standalone performance carmaker, but the company is still working its magic on existing Volvo models. Case in point: Volvo has just released a new software update developed by Polestar that makes certain AWD models more fun to drive by increasing the torque distribution to the rear wheels.

According to Volvo, the optimization software increases the amount and frequency of torque sent to the rear wheels, resulting in improved steering with enhanced turn-in, better cornering control, and improved traction when pulling away for a more engaging drive.

"We are always fine-tuning the driving experience of Volvo cars and this upgrade makes the all-wheel-drive both smoother and more dynamic," said Henrik Green, senior vice president of research and development at Volvo Cars.

The increased rear-wheel torque distribution is activated by simply selecting the Dynamic drive mode or disengaging the Electronic Stability Control. It's the latest of many improvements added to current Volvos in recent software updates, including sharper throttle response, faster off-throttle response, quicker gear changes, and more power.

Polestar's software optimization will only be available to new Volvo cars built on SPA and CMA architecture from the model year 2019 onwards equipped with all-wheel drive. That means AWD versions of the Volvo 90 Series, 60 Series and XC40 will be more tail-happy when the software update rolls out this month.

Volvos equipped with the T6 Twin Engine or the T8 Twin Engine hybrid powertrain won't need the update, however, since they already have rear-drive bias thanks to an electric motor driving the rear axle.
