While not quite as wild as the aforementioned Polestar versions, the T6 engine in Volvo’s newest models extracts lots of power from just four cylinders. A turbocharged and a supercharger work together to deliver lots of boost and thus 316 hp from the relatively small engine. That means that the Volvo that lines up next to you, by the way, could have more power than your Subaru WRX STI.
