Volvo is not the first brand that comes to mind when thinking about high-performance vehicles, and aside from a handful of R performance models, such as the 300hp turbocharged S60 R, they have always concentrated more on safety than on the thrill of the drive.These days Volvo works closely with Polestar when it comes to tuning their cars, and as Jay Leno discovers in the latest installment of his online series, the tuning specialist has plans for future Volvo high-performance vehicles.As a preview, Polestar boss Hans Baath visited Jay Leno\'s Garage with a \'Swedish racing green\' customized C30 Polestar racing concept that comes equipped with 451hp, a AWD system and Brembo brakes. Apparently that\'s nothing compared to what the kids manage to get from the engine, but at least its street legal.
