Mercedes-AMG vehicles are known for their high performance - but many models are electronically limited to a top speed of 250 km/h as standard. Some models with the AMG Driver's Package or S variants have a slightly increased VMAX, but the full potential remains untapped. π
The limitation is not only stored in the engine control unit (ECU) , but also in the Central Powertrain Controller (CPC) . Simply adjusting the ECU is therefore often not enough - the CPC must also be optimized for complete activation.
βοΈ Why is the VMAX limited at the factory?
The factory limitation occurs for several reasons:
- πΉ Protection against excessive load on tires & brakes
- πΉ Compliance with legal requirements & insurance guidelines
- πΉ Limitation by CPC to enforce torque and VMAX locks
Even if the engine control unit can provide higher power, the top speed remains limited by the CPC. Therefore, a complete release of the VMAX is only possible through optimized coordination of all relevant control units .
π₯ How does VMAX cancellation work?
In Mercedes-AMG vehicles, several control units are involved in the limitation. A clean VMAX cancellation therefore includes:
π Adjustment of the CPC (Central Powertrain Controller)
- β Removal of the factory torque and VMAX limitation
- β No limitation due to load axis manipulation
βοΈ Optimization of the ECU (engine control unit)
- β Adaptation of the maps for maximum speed
- β Ensure that the ECU takes over the VMAX release
π₯ Tuning of the TCU (gearbox control)
- β Optimization of shift strategies for higher speeds
- β Adjustment of the transmission torque releases
β Which AMG models benefit from the VMAX cancellation?
Our solution is available for all current AMG models with VMAX limitation, including:
- β A 45 AMG (W177) β limited to 250 km/h as standard
- β C 63 AMG (W205/W206) β CPC-based limit
- β E 63 AMG (W213) β VMAX limitation via CPC & TCU
- β GLC 63 AMG (X253/C253) β full activation possible
- β GT 63 S AMG (X290) β electronic limit adjustable to 315 km/h
