Volvo Cars, the prestige car maker, and Polestar, the performance brand owned by Volvo Cars, have announced the launch of the quickest cars they have ever made – the new 270kW Polestar S60 sedan and V60 estate.

The car makes the zero to 100km/h sprint in 4.7 seconds and is limited to a top speed of 250kmh, powered by a specially-enhanced version of Volvo’s award-winning four cylinder Drive-E powertrain.

Polestar has taken an original S60 and V60 and added a bigger turbo, a supercharger, new conrods, new camshafts, a larger air intake and a higher capacity fuel pump to augment the engine, and matched it with a BorgWarner four-wheel drive system and the new Polestar-optimised eight-speed Geartronic automatic gearbox.

On top of this new performance-optimised equipment, Polestar has reduced the car’s weight. The Volvo S60 and V60 Polestar are 24 kilos lighter over the front axle and 20 kilos lighter in total compared to the previous model years.

“By any measure these cars are seriously quick,” said Kevin McCann, Managing Director of Volvo Car Australia.

“When they arrive in Australia later this year people will be genuinely impressed.”

“They are born at the racetrack, but built for the road. The cars are very composed through corners, with lots of traction and enough low-end torque to make them very, very quick. They combine Polestar’s 20 years of racing pedigree with Volvo’s inherent pragmatism and engineering heritage. The end result is two very quick but functional performance cars that can be driven on normal Australian roads every day of the year.”

These two new models also mark the globalisation of the Polestar brand.
