Polestar is a super efficient tuning software that optimizes the output of Volvo's T5 and T6 engines. For the T5, it increases horsepower from 227 to 250 hp, and torque from 238 to 273 lb. ft. For the T6, horsepower goes from 300 to 325 hp, and torque from 325 to 354 lb. ft.
Polestar provides the kind of enhanced performance that kicks in when it's needed most. Polestar will not impact the certified fuel economy or emissions, and Volvo's factory warranty is not affected provided it is installed at an authorized Volvo retailer.
