367 HP to 420 HP | 500 Nm to 620 Nm
The Mercedes-AMG GT 43 uses the M256 engine — a modern inline-6 with turbocharging and EQ Boost assistance, combined with advanced torque and thermal management.
For this Stage 1 setup, the goal was not maximum peak output, but usable performance with full system integrity.
Key focus areas:• optimized torque request and limiter coordination• refined boost control in the mid and upper range• smooth, predictable power delivery• thermal and drivetrain limits fully respected
The result is a noticeable performance increase while maintaining OEM-level comfort, drivability and reliability.
This is how modern AMG platforms should be calibrated: clean, controlled and predictable.
