Volvo has introduced a Polestar-developed software upgrade for its all-wheel drive (AWD) cars (the 90 series, 60 series and XC40 cars), which increases torque distribution to the rear wheels. The optimization software increases the amount and frequency of torque distributed to the rear wheels, with the aim of improving steering with enhanced turn-in, better control and engagement when cornering, and improved traction when pulling away. The AWD optimization is engaged by selecting the ‘Dynamic’ drive mode, or disengaging the electronic stability control.
The rear-wheel torque distribution feature adds another optimisation area to the latest Polestar software upgrade. The five existing areas include sharper throttle response, faster off-throttle response, quicker gearchanges, optimized gearshift points and in-corner gear holding, as well as increased engine output.
“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, SVP of R&D at Volvo Cars.
