The 2017 Polestars are said to be the quickest cars Volvo has ever made. The new Polestar S60 sedan and V60 wagon run zero-to-60 mph in as little as 4.4 seconds with a (limited) top speed of 155 mph, powered by a specially-enhanced version of Volvo’s four-cylinder Drive-E powertrain.

The two new Polestar models begin the globalization of the Polestar brand.

Polestar has taken an original two-liter Drive-E engine from standard V60 and S60 models and added a bigger turbocharger, a supercharger, new connecting rods, 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-optimized eight-speed Geartronic automatic gearbox. Helping the F+MA equation, the Volvo S60 and V60 Polestar are 53 pounds lighter over the front axle and 44 pounds lighter in total compared to the previous model years.
