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.
