Polestar Engineered will also be offered on the new V60 estate and XC60 SUV from next year, available globally in limited numbers via Volvo dealerships and Care by Volvo, the company's premium vehicle subscription service.
That's not going to change, either.
Volvo has confirmed that the top S60 model will use a reworked version of the T8 Twin Engine's hybrid powertain, which comprises a 2.0-litre four-cylinder engine mated to an electric motor. Expect the high-performance Polestar Engineered model to combine the best attributes of the V60 wagon with the powerful persona of the Polestar 1 and the elegant looks of a sedan.
Building on the standard T8's 394bhp combined power figure, Polestar's very contemporary way of increasing power via upgraded software brings power up to an even more impressive total of 408bhp.
Volvo promises to add lighter wheels that give on-lookers a view of the gold-painted Brembo brake calipers. Recalibrated multilink front and rear suspensions use Öhlins shock absorbers that stiffen the springs and dampers but shouldn't ruin overall ride quality.
That all sounds good, except for gold being the new hallmark color. Polestar will tune that powertrain with a new engine control unit that boosts it to 415 horsepower and 494 pound-feet, up 15 horses and 22 pound-feet, the Swedish automaker announced in a release one week before it unveils the new S60 at the opening of its Charleston, South Carolina assembly plant, sole manufacturer of the new sedan.
Additionally, new lightweight wheels reduce unsprung mass, while chrome exhaust tailpipes and gold-coloured seatbelts emphasise the car's Polestar links.
Volvo says the Polestar Engineered treatment will be "available globally in limited numbers", though it's unclear if there's an actual production cap.
