Underneath the unassuming bonnet of the marque’s Mercedes C63 AMG and BMW M3 rival lies a highly tuned version of the firm’s 3.0-litre T6 straight-six motor – including revised combustion chambers, inlet manifold and conrods - which is mated to a large Garrett 3171 turbocharger.
Together, they produce 501bhp and 424lb ft of torque, which is enough to slash the Mercedes C63 AMG’s 0-62mph time by 0.6sec down to 3.9sec. Top speed is said to be ‘more than 186mph’ and drive is sent through all four corners via a six-speed close-ratio manual gearbox.
Compared with the standard T6 AWD Volvo model, these figures represent a power boost of 197bhp and 100lb ft torque. Top speed is also 31mph higher and 62mph sprint time 2.2sec quicker.
Modifications of the 186mph super saloon’s chassis comprise a 30mm lower ride height than the standard car, as well as a wider track front and rear by 20mm and 40mm respectively. For maximum traction, the Polestar sits on 19-inch alloys wrapped in 265/30 R19 rubber.
Anti-roll bars, engine mounts and cross members are also beefed up to cope with the hot S60’s considerable power hike and for added stopping power, Polestar has fitted strong, ventilated Brembo discs, measuring 380mm up front and 302mm at the rear. A 3.5-inch stainless steel exhaust system has also been fitted to improve air flow and to enhance the car's engine note.
To keep the concept’s 1640kg body stable at high speed, the Polestar’s ground-hugging body is also 20mm wider. Additional downforce comes courtesy of a lower front splitter, larger rear wing and a carbonfibre diffuser.
