Volvo and Polestar offer post-sale software upgrades

For the T6 engine in the 2010 Volvo XC60 and 2009-2010 XC70 Polestar will offer a bump in output from 281 hp to 311 hp.

So it’s no big surprise that Don is plotting to celebrate the 50th anniversary of Donald Campbell’s land and water world speed records in 2014 with a new, limited edition supercar, taking time out from making Bluebirds to break the electric land speed record. But the anniversary is in 2014, so Campbell junior has decided that his celebratory supercar – the Bluebird DC50 – will be an electric supercar rather than an ICE one.
