The new Polestar Performance Optimisation package for the Volvo S90 and V90 twins has been unveiled, and is claimed to improve throttle response, shift speed and overall engine performance.

According to Volvo, the new upgrades make the S90 sedan and V90 wagon “more dynamic and fun to drive”.

That said, Volvo has yet to state if the new package liberates any extra power or torque from the engine, or if there’s a measurable improvement in the S90/V90’s performance figures.

According to Volvo Australia, the Polestar Performance Optimisation package will be available when the S90 goes on sale locally in October. Similarly, the package will be available at launch for the V90, which should arrive Down Under a few months later.

In Europe, the Polestar package is only available with the D5 diesel and the T6 petrol models.

High-performance Polestar models

Peter Mertens, head of research and development at Volvo, has already confirmed with Motor Trend that the Swedish automaker is prepping high-performance Polestar-branded variants of the S90 and V90 with around 450kW of power.

As CarAdvice reported last year, the new S90/V90 Polestar models will use the plug-in hybrid drivetrain from the 235kW/400Nm T8 as their foundation.

Mertens told the American magazine that the T8’s 65kW rear-axle electric motor will be replaced by a more powerful 115kW unit.

Under the bonnet, the S90/V90 Polestar will use a supercharger and two electrically-driven compressors to extract around 335kW from the company’s 2.0-litre four-cylinder engine.

This new engine setup will be similar in concept to the 336kW triple boost motor that was unveiled in 2014, although that engine had two parallel turbochargers and a single electrically driven compressor.
