Geely-owned Volvo Cars has introduced a new Polestar-developed software upgrade that it says increases torque distribution to the rear wheels of Volvo cars equipped with all-wheel drive (AWD), for 'more dynamic driving'.
The optimisation software, developed by Polestar, increases the amount and frequency of torque distributed to the rear wheels, which Volvo says improves steering with enhanced turn-in, better control and engagement when cornering, and improved traction when pulling away.

"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 AWD optimisation is engaged simply by selecting the Dynamic drive mode, or when the Electronic Stability Control is disengaged.
Volvo says the new rear-wheel torque distribution feature adds another optimisation area to the latest Polestar software upgrade. The five existing areas, it says, include sharper throttle response, faster off-throttle response, quicker gearchanges, optimised gearshift points and in-corner gear holding, as well as increased engine output.
The Polestar AWD optimisation will be available for petrol and diesel models of the Volvo 90 series, 60 series and XC40 cars, from August 2018 onwards.
