Volvo S60 Polestar Concept

Polestar takes factory Volvos, tunes them up to 11 and releases them on the unsuspecting public. You can buy a Polestar-enhanced S60 sedan right now, but at the Los Angeles Auto Show, the Sino-Swedish maker brought a Polestar concept that dwarfs anything the company has made before.

The Volvo S60 Polestar Concept will carry the same inline six-cylinder engine as the standard car, but it will be tuned to pump out 508 hp and 424 lb-ft of torque. That's 208 more horses and 99 more lb-ft in a car that's already very quick.

"We approached this project by looking at the production Volvo S60 as a platform for a potential race car...and...that data went into the design of the S60 Polestar Concept," explained Jan Andersson, chief engineer at Polestar.

The chassis is lower, wider and reinforced. The Haldex all-wheel-drive system is modified for the extra grunt while an Öhlins suspension keeps things buttoned down.

The cylinder head and combustion chambers are modified, as are the inlet manifold and air intake. A Garrett 3171 turbo compresses air while a Ferrita 3.5-inch exhaust spits it out the back.

As for stats, the Polestar Concept can get to 62 mph in just 3.9 seconds, on its way to a top speed of 186 mph.

Volvo currently offers Polestar upgrades to the S60 sedan and XC60 SUV.
