Volvo set a corporate high-water mark for speed today by launching two new Polestar models, each with enough power to make a tenured Vermont professor blush.

Dropping two cylinders while gaining 22 horsepower, the upgraded S60 and V60 Polestars are part of Volvo’s effort to boost the visibility of its performance division.

The 2.0-liter Drive-E four-cylinder in the S60 and V60 Polestar (replacing the previous blown straight six) was worked over by Polestar engineers to make 367 horsepower and 347 pounds-feet of torque. The mill, which makes 240 horsepower in T5 models, gains muscle from a supercharger, larger turbocharger and air intake, and a higher-capacity fuel pump.

I’m a horrible car guy; I dislike convertibles. It’s not really for the usual reason car buffs dislike going topless, it has nothing to do with the inevitable loss of stiffness or added weight and complexity and everything to do with the reduction in practicality. I realize that a practical convertible is something of an oxymoron, but some are worse than others. It’s no wonder the convertible landscape is littered with has-beens, convertible sales only account for 2% of passenger car sales in North America and premium ‘verts are an even smaller part of the pie. It is therefore no surprise that the G37 convertible is only the second ever Infiniti convertible.
