Volvo expands Polestar software upgrade to more models

Volvo is spreading the horsepower love around its fleet with a wider array of Polestar Performance software upgrades. 2011 and 2012 XC60, S60 and XC70 models equipped with a T6 engine are now available with a software upgrade that adds in 25 horsepower and 30 pound-feet of torque without impacting fuel economy. Those improvements put the engine's final figures at 325 horsepower and 355 pound-feet of torque, though the extra grunt won't come cheap. Volvo says that the software package will set buyers back a hefty $1,495 including destination when it goes on sale on December 5th. The company isn't saying why the T6 software costs $200 more than the 23-horsepower upgrade available on vehicles equipped with the automaker's T5 engine. That boost can be had on the C30, C70 and S40, and will eventually show up on the V50. Hit the jump for the brief press release.
