Polestar, the performance brand of Volvo Cars, has unveiled its 2018 version of the Volvo S60 and V60.

The new models come complete with additional aerodynamic components made from lightweight carbon fibre material that increase downforce by 30% for improved performance and handling.

Only a limited number of 1,500 vehicles will be produced, with all cars receiving a unique number on the tread plate.

The new aerodynamic exterior package has been developed jointly by the engineers of Polestar and Cyan Racing, the motorsport partner of Polestar, with data and learnings derived from the World Touring Car Championship (WTCC) programme where the team is involved in the title fight.

Other enhancements include high-gloss black Polestar diamond cut wheels, carbon fibre door mirror casings and a new colour; Bursting Blue Metallic. The interior has been updated with new seat upholstery, blue contrast stitching and Polestar embroidering.

More than 250 components have been changed compared to the standard Volvo model to create a car with all the usability and practicality of the Volvo S60 and V60, but also delivering all-year round sports car performance. Key component changes include the adjustable Öhlins shock absorber system and six-piston Brembo brake calipers with 371mm discs.

A 367PS Drive-E engine allows the car to accelerate to 62mph in 4.7 seconds while offering emissions of 179g/km of CO2.
