A performance-focused hybrid could help the brand make a big splash as it diverges from parent Volvo.

Polestar's first dedicated model could be a performance-focused hybrid coupe, according to an Autocar report.

Volvo recently announced plans to transform Polestar from a tuning accessory trademark to a dedicated brand with its own vehicles and unique styling, but presumably based on a common platform architecture.

Citing unnamed insiders, the latest rumors suggest Polestar has been preparing for a more prominent role since Volvo officially acquired the tuner two years ago. Its first dedicated model is expected to be presented to the public as early as September at the Frankfurt motor show.

Autocar speculates the coupe could be closely related to the Volvo S60, but will not be adorned with a Volvo badge. The XC90's T8 'Twin Engine' powertrain is a likely candidate to reach the 600-horsepower benchmark, jumping from the crossover's current 421-pony output.

The Polestar strategy is said to be particularly important for Volvo and parent company Geely, simultaneously launching Volvo's rivalry with German performance sub-brands, such as AMG and BMW M, and fulfilling a broader commitment to electrified powertrains.
