But the new "Polestar Engineered" offering that was specifically developed for its "60" range appears to be a bridge between the two, in the same way that BMW's M Performance cars like the M240i straddle the lines between normal BMW's and devilish M Division cars.
Fine-tuning of the engine's control unit increases the S60 electrified T8 Twin Engine output to 415hp* combined, with 670Nm of torque - the standard T8 Twin Engine delivers 400hp* and 640Nm combined. Like that vehicle, these high-spec "60 series" models will incorporate Polestar's new aesthetic trademarks, such as gold-painted brake calipers, Brembo monoblock units in this case.
Volvo will reveal the new S60 next week at its first USA manufacturing plant in Charleston, South Carolina.
Polestar may be its own brand now, but it will also continue to act as the performance arm of Volvo for the foreseeable future. Instead there will be upgrades offered under the Polestar Engineered label.
Suspension tweaks include the addition of Öhlins shock absorbers with dual-flow valves, as well as the adoption of strut bar and adjustable shock absorber designs from the Polestar 1 plug-in hybrid performance auto. The software upgrades improve fuel consumption and emissions-neutral performance, and refines the automatic gear selection.
The upgrade will include new lightweight alloys framing gold-painted brake callipers, with that hue set to become the new signature colour for Polestar Engineered components. Seatbelt straps are gold, too, and the vehicle comes with Polestar emblems and black chrome exhaust pipes.
The regular T8 is powered by a 2.0-litre turbocharged petrol engine driving the front wheels supplemented by an electric motor at the back, giving a total of 385bhp. "All components have been fine-tuned to work together, delivering a responsive and exciting drivers' auto".
