Volvo's S60 R-Design is the company's most powerful production vehicle, with output boosted an additional 25 hp from the normal S60 T6's 300-hp output, thanks to development undertaken by Volvo's racing and performance parts partner, Polestar.
By increasing turbo pressure and recalibrating the engine-management system, Polestar found the extra power (along with a 9 percent torque improvement, peaking at 354 lb-ft), without hurting the car's fuel-consumption ratings. Appropriately, the increase in engine performance is accompanied by various suspension tweaks.
All of the springs were shortened by 15 millimeters and are 15 percent stiffer, and monotube rear shocks replace twin-tube equivalents for faster response. The rear bushings are 20 percent harder, and the front antiroll bar has 20 percent more resistance. Up front, a strut brace ties the front towers together. This stiffer new chassis rides on 18-inch Ixion alloy wheels shod with high-performance summer tires.
The R-Design model is distinguished by exterior styling additions that include a front facia, a piano-black grille and a new rear diffuser. Inside, the car gets unique seats with extra cushion bolstering and an embossed R-Design logo across the front-seat backrests. The interior also has a sport steering wheel with R-Design logo, gear selector, sports pedals, floormats and a blue watch-dial instrument cluster.
