Polestar is the skunkworks responsible for hi-po Volvos like the V8 Supercars-inspired S60 and V60. The company’s new generation optimisation package for the flagship XC90 wrings out 314kW and 680Nm (up 11kW and 40Nm), making it the most powerful production Volvo ever.
Somewhat amazingly, all that grunt comes from a 2.0-litre, four-cylinder engine, though the T8’s ‘Twin Engine’ setup uses every known power-adder under the sun to get such huge numbers out of so little. The four-pot petrol engine is supercharged and turbocharged, direct injected and assisted by an electric motor.
The latest Polestar-tuned XC90 is based on the plug-in hybrid T8 ‘Twin Engine’ powertrain, which combines a 2.0-litre turbocharged and supercharged four-cylinder engine with an electric motor.
The Polestar-fettled twin-charged petrol engine has been boosted by 14kW and 40Nm, increasing its outputs from 235kW/400Nm to 250kW/440Nm, although the electric motor appears to be untouched, generating the same 65kW/240Nm.
The XC90 T8 will be immediately available in select markets and will launch in the US in October. The EPA rates the standard XC90 T8 at 53 mpg-e (4.4 L/100km) in EV mode and 25 mpg (9.4 L/100km) combined city/highway driving.
The XC90 Polestar, which is available now, follows the S90 and V90 Polestar models (pictured above) announced last week, which feature similar multi-point performance upgrading.
