沃尔沃计划计划向更多国家销售S60和V60 Polestar，从先前的13个国家增加到47个国家。为了满足更大的市场需求，沃尔沃计划将这两款车的年销量增加一倍，从原来的750辆增至1500辆。同时，工程人员计划将这两款车搭载的引擎从原来的350马力3.0升六缸涡轮增压换成2..0升Drive-E涡轮和机械增压四缸引擎。虽然看起来似乎是降级了，但新引擎配备了更大的涡轮增压器和进气系统，新的凸轮轴和更大容量燃油泵。其结果是，这两款车的功率提升至270千瓦/367马力，比原来的引擎增加了12.5千瓦/17马力。不过，坏消息是，扭矩从原来的500牛米降至470牛米。与引擎搭配的是经过优化的八速Geartronic自动变速箱和博格瓦纳四驱系统。车辆百公里加速时间为4.7秒，最高时速经过电子限速为250公里。由于搭载了排量更小的引擎，车重也降低了20公斤。这两款车的百公里油耗为7.8升，每公里二氧化碳排放量179克。除了搭载新引擎，新车还配备新的20英寸轻质轮圈，371毫米刹车盘和重新调校的电子助力转向系统。
Stronger Volvo S60, V60 Polestar get 4-cylinder engine
Good news for fans of the S60 and V60 Polestar as Volvo has decided to expand market availability from the previous 13 to 47 countries. In order to meet what will obviously be a significantly increased demand, Volvo has plans to double annual production of the two performance models from 750 to 1,500 units.
The good news continue as the Polestar-tuned duo now packs more punch after the engineers swapped the 350-hp turbocharged 3.0-liter six-cylinder engine for a four-cylinder turbocharged and supercharged 2.0-liter Drive-E. While this may seem like a downgrade, the engine has a bigger turbocharger compared to the regular T6 and also comes with a larger air intake, new camshafts, and a higher capacity fuel pump.
As a result of all these modifications, the Volvo S60 and V60 by Polestar now have 367 horsepower (270 kilowatts), a healthy increase of 17 hp (12.5 kW) compared to the previous models. However, the bad news is torque has decreased from 369 pound-feet (500 newton meters) to 347 lb-ft (470 Nm). The engine works with a new eight-speed Geartronic automatic gearbox optimized by Polestar which sends the power to a BorgWarner four-wheel drive system.
Just like before, the Polestar pair has an electronically-limited speed of 155 mph (250 kph), but the sprint to 62 mph (100 kph) has decreased by 0.2s to 4.7s. The boost in performance was achieved not only by adding more horsepower, but also by putting the cars on a diet. Without going into details, Polestar says it was able to shave off a total of 44 pounds (20 kilograms) and improved weight distribution by cutting front axle load by 53 lbs (24 kg).
Even though the cars are all about performance, Volvo mentions the Polestar duo has a combined fuel consumption of just 7.8 liters / 100 km with equivalent CO2 emissions of 179 g/km. The new model year also comes with fresh 20-inch lightweight wheels, 371-mm slotted brake discs, and a recalibrated electro-assisted power steering.
