One week after Volvo's tuning arm revealed more powerful versions of the all-new S90 and V90, Polestar now introduces the Optimization Program to the company's flagship SUV, the XC90. Apart from boosting maximum output, Polestar also claimed that they were also able to improve five key areas of the powertrain: throttle response, gear holding, speed, precision and overall engine performance.

”Just a week after the introduction of the S90 and V90 optimization, we move forward by launching our optimization for the exciting and technically advanced XC90 T8 Twin Engine. This gives customers who want a new level of driving pleasure with their XC90 an easily accessible and attractive performance increase,” said Niels Möller, chief operating officer of Polestar.

The T8 Polestar Optimization for the XC90

Originally, the 2.0-liter turbocharged inline-four produced 320 PS and 400 Nm of torque while the electric motor provided 87 PS and 240 Nm of extra power. With the Optimization Program in play, the range-topping XC90 T8 now produces a combined output of 421 PS along with 680 Nm, upping the ante by 15 PS and 40 Nm compared to the standard 406 PS / 640 Nm.

The additional boost in power now enables the XC90 T8 to go from 0 -100 km/h in 5.5 seconds, without affecting its claimed 47.6 km/l fuel average and 43 km electric range.

As mentioned earlier, Volvo also optimized the car's gear hold function and throttle response among others. According to Polestar, this will allow the XC90 T8 to maintain power balance during cornering at high lateral g-forces.

As of now, the Optimization Program is now available in Europe, with the US market to follow suit come October 2016. There is no word yet if the Polestar Optimization program will arrive in the country.
