Chicago Auto Show: Volvo S60 and V60 Polestar image

Volvo has brought its S60 Polestar sedan and V60 Polestar wagon to the 2014 Chicago Auto Show, for their 2015 model years.

The two vehicles have made their global debut today, during the automotive event in Windy City, and they are based around the standard versions of the S60 and V60. The Polestar editions are said to combine safety and comfort, which is what customers expected from a Volvo car, along with several upgrades which will make them some of the fastest models with the carmaker’s badge, in history. Upgrades include the stiffer new springs, the Ohlins shock absorbers, larger ventilated front and rear disc brakes, with Brembo calipers and more.

Some elements from motorsport, aerodynamically speaking, are being carried over to the S60 Polestar and V60 Polestar, and are said to increase downforce and to allow more streamlined airflow. The 3.0 liter straight six-cylinder engine has been upgraded and it’s producing a total output of 345 HP and 369 lb-ft of torque, available from just 2,800 rom. These figures have been achieved b installing a new turbo, an intercooler, recalibrating the ECU and improving the airflow with a stainless steel exhaust system. The 0 to 100 km/h (62 mph) sprint takes 4.9 seconds for each model and top speed has been electronically limited to 250 km/h (155 mph).
