D5 Over Boost
The Polestar Optimisation software for the D5 (68) engine offers an exciting enhancement. Polestar have introduced an Over boost function that provides an additional +20nm Torque and +15hp power for up to 20 seconds once the peak power of the engine has been reached. This additional power and torque is over and above the already increased output figures that the Optimisation provides so you get an impressive boost when you need it most. The standard D5 (68) engine produces 235hp and 480nm torque. When this engine is Optimised and is in Over boost mode, the figures are increased to 255hp and 520nm torque.

Starting from 18w48 the Polestar Optimisation SW for D5 (engine code 68, D4204T23) will be
enhanced with an overboost function.
Power and Torque will be momentarily* increased with up to +20 Nm torque and +15 Hp over and
above the already increased Optimisation output figures.
Applicable models :
MY19: XC60, XC90, S/V90, V90CC D5 (68 engine code)
MY18: XC60, XC90 D5 (68 engine code)
Already optimised cars will automatically receive the additional overboost enhancement when the
car receives a SW upgrade via VIDA at the VCC workshop (i.e. Service 2.0).
