Swedish car brand Volvo has officially released its Volvo S60 Polestar Performance Concept on the sidelines of the Gothenburg City Race in Sweden. The vehicle was developed by Volvo Cars Official Motorsports and its racing and tuning partner Polestar for an as of yet unnamed client.
The engine is a Volvo T6 inline six (B6304T4) producing 508hp at 6,500rpm and 575Nm at 5,500rpm. The redline is placed at 7,100rpm. The powerplant has a modified cylinder head and combustion chambers, a modified inlet manifold and air intake, special manufactured conrods, a Garret 3171 turbo and a Ferrita 3.5 inch stainless steel exhaust system.
The powertain offers a reinforced M66C (close ratio) manual six-speed gear box converting the power from the engine to the Haldex E-LSD at the rear and the Haldex Gen4 XWD system. Stopping power is achieved via Polestar-Brembo six piston calipers and 380mm ventilated discs at the front and Polestar-Volvo calipers and 302mm ventilated discs at the rear. Special brake cooling air intakes were fitted to the front.
Chassis improvements feature a lowering of 30mm, Öhlins three-way shock absorbers, reinforced anti-roll bar front and rear, track width increase with 20mm front and 40mm rear, Polestar-tuned EHPAS steering, Stabilising X-members front and rear, modified control-arms with uniballs front and rear, reinforced bushings in sub-frame and control-arms and modified engine mounts. The sports car rides on Polestar 9.5×19 inch rims shod in 265/30R19 tires.
The total weight is 1,640kg and it received an optimized weight distribution. The aerodynamics were tested in Volvo’s windtunnel and include a lowered front splitter and larger rear spoiler to reduce high speed lift, a carbon fiber diffusor and a body which has been widened 20mm front and rear.
On the inside, the cabin has Polestar designed seats with increased support. Alcantara was fitted to all functional areas such as the steering wheel, gear knob, and seats to ensure maximum grip. The center console was lowered for optimised gear-lever ergonomics.
