Volvo's 155mph Polestar estate car The limited edition car is based on the current generation of V60 (an S60 Polestar saloon is available in other markets, but won't come to the UK), which is then tuned by motorsport outfit Polestar, all the while maintaining Volvo's own servicing schedule, safety features, emissions ratings and warranty. Christian Dahl, CEO of Polestar, said: "With the introduction of the V60 model, we are proud to continue the heritage of fast Volvo estates like the racing 850 BTCC, a tradition deeply rooted among Volvo enthusiasts." As well as upgrading the six-cylinder turbocharged T6 petrol engine (which now produces 369lb ft of torque at 2,800rpm), Polestar has fitted 80 per cent stiffer springs, Ohlins shock absorbers and 20in wheels. The automatic gearbox uses steering wheel-mounted paddle shifters and power is sent to the road via a Haldex four-wheel-drive system. Braking is by six-piston calipers. The exterior styling has been tweaked based on data from wind tunnel testing, and includes a new front splitter and a rear spoiler and diffuser, while the interior has Polestar-branded seats and gearlever. "Our motorsport co-operation with Polestar has been going on for almost two decades and it is rewarding to see how Polestar can use their experiences from motorsport to engineer such an exciting and competent car," said Derek Crabb, Motorsport Director at Volvo. The Polestar V60, which is said to place an emphasis on driver enjoyment in all conditions, goes on sale next summer. Volvo is yet to announce how much it'll cost.
