Officially sanctioned Volvo motorsports team and tuner, Polestar Peformance, is taking their relationship with their Gothenburg auto maker one step further with the development of a high-performance Volvo S60 production model.

According to Swedish magazine Teknikens Varld, the Polestar S60 is Volvo's answer to the BMW M3 and the Mercedes C 63 AMG super sedans. Spy photos sent in from a Teknikens Varld reader, show a heavily camouflaged vehicle with a widened track and broadened wheel arches in all four corners, plus sporty wheels that are a bit wider than the normal wheels.

After some digging at the Swedish registration office, the vehicle in the spy photos is listed as a T6 AWD with 304 horsepower, but the Swedish magazine is doubtful and believes a V8 engine is used instead. In fact, it is the same Yamaha built V8 currently employed in the Volvo XC90 SUV and S80 producing a minimum of 400 HP (294 kW / 394 bhp).

In the aforementioned vehicles, the 4.4-liter aluminum DOHC Yamaha engine produces 315 HP (232 kW / 311 bhp) while in the Noble M600 it develops 650 HP (478 kW / 641 bhp) with the aid of two turbochargers. Teknikens Varld also speculates that Polestar will employ a sequential gearbox tied to a Haldex all-wheel-drive system.

As an example of what they can do, it should be noted that Polestar revealed the C30 Performance Concept at the Gothenburg Motor Show in 2010. Using the 2.5-liter T5 engine, Polestar added a larger intercooler and a KKK 26 turbocharger causing power to climb from 230 HP (169 kW / 227 bhp) to 411 HP (302 kW / 405 bhp). Other goodies include an aerodynamic body kit, a Haldex AWD system, Öhlins shock absorbers and springs, Brembo brakes, and 19-inch BBS wheels outfitted with Pirelli P Zero tires.

If the high-performance S60 becomes reality, we could see an announcement sometime in 2013.
