Volvo has announced a new software upgrade, developed by its Polestar division, which increases the torque distribution to the rear wheels of all-wheel drive vehicles built on the company’s Scalable Product Architecture (SPA) or Compact Modular Architecture (CMA).
The company claims by increasing the amount and frequency of torque going to the rear wheels it has come up with a “more engaging drive”, as well as improving steering turn-in, cornering control, and traction under acceleration.
For vehicles equipped with the Polestar software upgrade, the “optimised” all-wheel drive setup is used whenever the car is in the Dynamic driving mode or traction control is disengaged.
Volvo says the retuned all-wheel drive code will be added to the Polestar software upgrade package, which already includes sharpened throttle response, snappier gear changes with revised shifting points, and increased engine output.
Polestar’s upgraded all-wheel drive software will be available for 2019 model year S90, V90, XC90, S60, V60, XC60 and XC40 models powered by a petrol or diesel engine, but without electric motor assistance.
