VOLVO is expected to launch a high-performance, German-baiting version of its new S90 flagship sedan, featuring Polestar badging and a hybrid drivetrain.

The Polestar version will rival the likes of the Mercedes-AMG E63 and BMW M5, and spearhead Volvo’s attempt to break Germany’s stranglehold on the executive express market.

Standard versions of Volvo’s new S90 sedan and V90 wagon were shown at the Detroit motor show, and our artist’s impression hints at how the future Polestar sedan could look.

A Polestar version of the V90 wagon is also mooted, to take the fight to Audi’s RS6 Avant.

Polestar is now a subsidiary of Volvo, which bought the Swedish tuning company last year.

The S90 is the second all-new model after the XC90 to be built on Volvo’s Scalable Platform Architecture.

The same platform will also spawn the next-generation S60 and V60 due in 2017, both of which will also receive the Polestar treatment.

Already confirmed to power top-spec T8 AWD versions of the standard S90, the T8 Twin Engine combines a 235kW/400Nm twin-charged 2.0-litre four-cylinder petrol engine with a 65kW/240Nm electric motor. It’s currently the most powerful engine Volvo makes and is capable of pushing the 2296kg XC90 to 100km/h in 5.6sec.

This suggests the all-wheel-drive S90 Polestar should hit 100km/h in less than five seconds, given its lesser kerb weight and more powerful drivetrain. The AMG E63 S and BMW M5, both of which are exclusively rear-drive in Australia, do the sprint in in 4.2sec.

The XC90’s influence is also obvious in the large tablet-style central screen, but long slabs of natural wood and higher-quality materials give the S90 a greater sense of plushness.

The S90 is packed with cutting-edge safety technology, as you’d expect from Volvo, including a world-first ‘large animal detection’ function that is linked to the automatic emergency braking system. Capable of recognising animals such as cattle and kangaroos, the system warns the driver and will even brake the car to avoid a collision.

Externally, the S90 moves away from the chunky, heavy-handed styling of recent large Volvo sedans like the slow-selling S80. It ushers in a more elegant look with short overhangs and ‘Thor’s hammer’ headlights, which will filter through to all modern Volvos.

Expect the regular S90 to hit Aussie roads in September.
