From the article:
This increases all Mercedes CLA 45 AMGs’ power from 360 hp / 265 kW / 450 Nm to 410 hp / 302 kW / 530 Nm. The German AMG performance specialist thus outdoes even the A 45 AMG’s facelift version (381 hp / 281 kW) by a huge margin. Incidentally, this does also apply to the electronically limited top speed, raised byperformmaster from 250 to 280 kph.
