The German tuner Posaidon has introduced an engine tuning for the
Mercedes-Benz A 45, CLA45 and GLA45 AMG models.
There are three different stages. The first one raises the power from the original 360 hp to 385 hp (283 kW) and 357 lb-ft (485 Nm) of torque. The second rewards drivers with 405 hp (298 kW) and 361 lb-ft (490 Nm), while the third stage provides 445 hp (327 kW) and 394 lb-ft (535 Nm) of torque.
Given that the Mercedes drivetrain is apparently not designed for torque above 368 lb-ft (500 Nm), Poseidon recommends that customers choose the first or second stages to avoid any issues.
