We are now offering a Stage 1 and Stage 2 software optimisation for the current Mercedes-AMG A 45 4MATIC and 45 S 4MATIC (W177). The turbocharged 2.0-liter four-cylinder engine with 387 hp/480 Nm and 421 hp/500 Nm in the S variant is significantly more powerful through our performance increases. With the Stage 1 software developed in-house, the compact sports car has an output of 470 hp/580 Nm torque. There is even more driving pleasure with the Stage 2 software, which achieves a 500 hp/590 Nm torque. In addition, Stage 2 offers a Vmax repeal, which results in 295 km/h.
