Volvo has revealed the next evolution of their Polestar V60 and S60 series cars and these boys in blue are the fastest cars to ever be produced by the company. Each car is fitted with supercharged 4-cylinder inline engines that now have a bigger turbo and various performance upgrades that include new camshafts, conrods, larger air intakes, and a high capacity fuel pump.
All that hardware helps the cars achieve a 0-62 time of 4.7 seconds and top speed is limited to 155 mph. Couple that with a Polestar-tweaked eight-speed transmission and a BorgWarner four-wheel drive system and you've got a car that's ready for anything. And yes, they'll be available in the USA.
