Polestar Engineered will debut on the new S60, which is set to be revealed at the inauguration of Volvo's first U.S. manufacturing plant in Charleston, South Carolina. The range-topping vehicle will be only available in T8 Twin Engine guise and sit above the R Design versions.
Polestar Engineered takes the S60 electrified T8 Twin Engine output from 400 to 415hp combined, with 670Nm of torque. Polestar emblems, black-chrome tailpipes and gold-coloured seat belts also serve to identify these flagship models.
Volvo's performance arm and electrified label Polestar has applied its engineering power to boost the new 60 series due to launch next week in two plug-in hybrid versions.
The new range variants are specifically developed by Polestar - Volvo's electric performance brand - and will sit above the current R Design trim.

And once again, he couldn't putt it into the Atlantic Ocean from one of the myriad beaches dotting the Southampton coast line. He bogeyed the hard par-3 11th after hitting into the bunker and leaving his next shot well short of the pin.
Henrik Green, senior vice-president of research and development at Volvo, said that the parts have been "fine-tuned to work together, delivering a responsive and exciting driver's car".
The S60 is set to be built in Charleston, South Carolina, the first time a Volvo has been produced in the US.
The Polestar Engineered multi-link front and rear suspension incorporates premium Öhlins shock absorbers with a dual-flow valve that allows stiffening in the springs and dampeners while retaining comfort. That's an increase of 11kW and 30Nm over the standard 298kW/640Nm T8 Twin Engine setup. Volvo says the Polestar Engineered tune actually improves fuel consumption and "refines the automatic gear selection". "All components have been fine-tuned to work together, delivering a responsive and exciting drivers' vehicle".
Keeping this power under control is a revised suspension that uses high-performance shock absorbers, along with an upgraded Brembo braking system - after all, what's the good in going fast if you can't bring things to a safe stop?
