Volvo fans may have to wait a little longer until the Swedish manufacturer pulls the covers off a Polestar version of the new S90/V90, but that doesn’t mean the firm’s performance brand hasn’t been busy.
Equipped with a new 2-liter four-cylinder twin-charged engine, borrowed from the S90 and XC90, the updated S60 saloon and V60 estate Polestar have dropped the previous 3.0-liter straight-six powertrain. Output rises to 367 PS (362 HP) and 470 Nm (347 lb-ft) of torque, or 17 PS (17 HP) more but 30 Nm (22 lb-ft) less over the previous versions.
The increased performance comes from a bigger turbo, a supercharger, new conrods, a higher-capacity fuel pump and a larger air intake, from Polestar, which help the 0 to 100 km/h (62 mph) sprint time lower by 0.2 seconds, to 4.7 seconds in the S60 and 4.8 sec in the V60, compared to their predecessors, while top speed remains electronically limited at 250 km/h (155 mph).
Despite the extra punch, Volvo states that the fuel consumption and CO2 emissions in the two cars are “at a class-leading level“, as they stand at 7.8 lt/100 km (30.1 mpg US) and 179 g/km in the S60 and at 8.1 lt/100 km (29.04 mpg US) and 186 g/km in the V60.
The 8-speed Geartronic automatic gearbox has been enhanced by Polestar and so has the four-wheel drive system. Moreover, the high-performance division is also responsible for shedding 20 kg (44 lbs) from the total weight, which helps the S60 tip the scales at 1,751 kg (3,860 lbs), while the V60 weighs 1,796 kg (3,960 lbs). Tweaked power steering and bigger brakes should furthermore enhance their performance, while the new 20-inch lightweight wheels will contribute to their fresh appeal.
The 2017 Volvo S60 and V60 Polestar are the quickest cars the performance brand has ever made and, with their introduction, the company will expand the number of markets where Polestar models are sold, from 13 to 47, while doubling production volume from 750 to 1,500 units annually.
