From the article:
As far as technical improvements, the vehicle has received an extra 90 PS due to a new tuning for the injection system and ignition and a slightly higher turbo boost pressure. The total power now stands at an impressive 600 PS (441 kW), while the peak torque reaches 750 Nm (553 lb-ft) at 4,800 rpm.
