The Volvo V60 Polestar has received a number of engineering upgrades for 2016, not the least of which is a power-hike from 350 to 367hp, courtesy of a new four-cylinder Drive-E engine.

Replacing the previous six-cylinder T6 unit, the new 2.0-litre four-cylinder engine sees the V60 Polestar sprint from 0-62 mph in 4.8 seconds, down from 5.0 seconds.

Top speed remains an electronically-limited 155 mph.

Polestar developments for this engine include a new, larger turbocharger, together with new conrods, camshafts, a larger air intake, and a new high-flow fuel pump.

Although slightly less torquey than the previous six-cylinder, with 470Nm versus the T6’s 500Nm, economy is said to have improved to 34.9 mpg, while CO2 emissions fall dramatically to 186 g/km – down from 237 g/km.

The V60 Polestar also now uses a Polestar-tuned 8-speed Geartronic automatic transmission, which continues to drive all four wheels through a Borg Warner four wheel-drive system.

As a result of the new, lighter power-train, the car’s overall weight has been reduced by 20 kg, while optimised weight distribution sees 24 kg removed from over the front axle.

Rather stoically, Niels Möller, Polestar Chief Operating Officer, said: “These cars are properly quick.  But they are more than that.  They combine Polestar’s 20-year racing pedigree with Volvo’s inherent pragmatism and engineering heritage. These are very quick cars that you can use every day of the year.”

That backs up what we found when we tested the V60 Polestar last year, back when it was a limited run model, although Volvo and Polestar have committed to increasing production to 1,500 units globally.

Other new features include redesigned 20-inch lightweight alloy wheels, re-calibrated steering, and new 371mm slotted front brake discs.

Prices for the new Volvo V60 Polestar will be announced later, with first deliveries expected in Q4 2016.
