Aiming to take the fight to Audi's new S4 Avant, the Polestar hits 62mph in 4.8sec – a 10th quicker than the Audi – and has a top speed of 155mph.
Replacing the turbocharged 3.0-litre straight-six from its predecessor, this new Drive-E engine is a better fit with Volvo's current engine line-up, which is comprised of only four-cylinder units. Despite losing a litre of capacity and two cylinders, the Polestar-tweaked engine boasts 362bhp – 17bhp more than the outgoing V60 Polestar.
Known elsewhere in the Volvo range – including in the S90 and XC90 – as the T6 engine, this twin-charged unit has been further tweaked by Polestar to include a bigger turbo, new conrods, new camshafts, a larger air intake and a higher-capacity fuel pump. It's the same basic engine as that found in the all-new FIA World Touring Car Championship race car, the Volvo S60 Polestar TC1 of Polestar Cyan Racing.
