Volvo has introduced Polestar upgrades on its flagship SUV - the XC90 - across the globe. Just so you know, Polestar is Volvo's performance brand and it is the first time that people would get to see the new seven-seater XC90 SUV with such upgrades. Known as Polestar Performance Optimisation, the upgrades improve the power and torque figures of both the D5 diesel and T6 petrol Drive-E engines.
The power and torque figures are improved particularly at medium revs where it’s most effective. They also make the accelerator responses even quicker, and alter the settings of the automatic gearbox to provide faster gearchanges and prevent gearshifts during rapid cornering, which could unsettle the car. These quicker and more precise responses to driver commands not only make the driving experience more dynamic, they ensure the car responds predictably during high-speed driving. The upgrades have been developed and designed by the engineers of Polestar and the racing drivers of Polestar Cyan Racing, the official motorsport partner to Polestar.
Thed Björk, reigning Scandinavian Touring Car Championship (STCC) champion and Polestar Cyan Racing driver, said: “The new Polestar optimisation is about making the car more dynamic and responsive to drive. We use the same philosophy as when optimising our race cars, to create a completely balanced package. And this is exactly what we have focussed on with the new-generation optimisations for Volvo cars: powertrain optimisation for real-life driving.” The maximum output of the D5 Drive-E engine is increased to 233 bhp and 500 Nm of torque, up from 225 bhp and 470 Nm, while the T6 Drive-E is boosted to 334 bhp and 440 Nm from 320 bhp and 400 Nm.
Nick Connor, Managing Director of Volvo Car UK, said: “These new Polestar Performance Optimisations make our cars and Drive-E engines even more dynamic and desirable. The combination of increased power and torque – especially at medium revs – and the changes to make the entire drivetrain more responsive ensure that owners will really feel the difference these optimisations make.” Finally, until the end of December 2015, all model-year 2005 to model-year 2015 all-wheel-drive Volvos can be upgraded with the Polestar Performance Optimisation. The Polestar upgrades do not affect the certified emissions and fuel consumption figures, service intervals or Volvo warranty cover.
