Volvo S60 and V60 Polestar revealed

Two new high-performance Polestar models, called the Volvo S60 Polestar and V60 Polestar, have been revealed. Both cars will be powered by a 3.0-litre turbocharged six-cylinder engine, and thanks to two new twin-scroll turbos and a new intercooler, the cars will have 345bhp. That's a bit less than the 500bhp Volvo S60 Polestar Concept, which was revealed in June 2012, but hardly a figure to sniff at.

Some of the main changes to the Volvo S60 and V60 Polestar models will be improved chassis rigidity, stiffer springs (by 80 per cent) and Ohlins performance shock absorbers. The cars also get 20-inch Polestar alloy wheels to increase the visual differences over the standard cars. A Haldex all-wheel drive system and six-speed paddle shift automatic gearbox will transfer the power on to the road, meaning both Polestar versions can go from 0-62mph in 4.9 seconds and on to an electrically limited top speed of 155mph.

The new models get a sporty new look but the tweaks should also improve aerodynamics. Changes include a new front splitter, rear spoiler and rear diffuser, all of which should increase downforce, keeping the cars settled in fast corners. Improved brakes have also bee fitted to the S60 and V60 Polestar: ventilated front discs and six-piston Brembo callipers. The interior has also been updated slightly, with Polestar-specific trim on the steering wheel and seats.

Further details and final production numbers will be released next year, with first deliveries beginning in June 2014. Prices are also yet to be released, but expect a price tag of around £40,000.
