Location Front Quarter Volvo S90 Mussel Blue

Juicy details regarding a hotter version of the new Volvo S90 and V90 have emerged from Motor Trend – the Polestar models will reportedly pack a massive 600 hp, utilising an uprated version of the plug-in hybrid powertrain that drives the T8 Twin Engine models.

According to Volvo’s senior vice president of research and development Dr Peter Mertens, the 2.0 litre Drive-E four-cylinder petrol engine can be boosted to almost 450 hp through the use of a supercharger and twin electric turbochargers.

This is quite a step up from the mill in the Twin Engine (and in the T6 models, minus the hybrid gubbins), which makes 320 hp using a supercharger and a turbocharger. Elsewhere, Volvo will also substitute the Twin Engine’s 87 hp rear-mounted electric motor for a more powerful unit.

All-in-all, the 600 hp output is around 200 hp higher than the T8 Twin Engine’s 407 horses, and should put it in good stead for the S90 and V90 Polestar to compete with the most powerful sports sedans and wagons in its class, including the upcoming F90 BMW M5 and W213 Mercedes-AMG E 63.
