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. 🚀

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.

⚙️ Why is the VMAX limited at the factory?

The factory limitation occurs for several reasons:

  • 🔹 Protection against excessive load on tires & brakes
  • 🔹 Compliance with legal requirements & insurance guidelines
  • 🔹 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 .

🔥 How does VMAX cancellation work?

In Mercedes-AMG vehicles, several control units are involved in the limitation. A clean VMAX cancellation therefore includes:

🚀 Adjustment of the CPC (Central Powertrain Controller)

  • ✔ Removal of the factory torque and VMAX limitation
  • ✔ No limitation due to load axis manipulation

⚙️ Optimization of the ECU (engine control unit)

  • ✔ Adaptation of the maps for maximum speed
  • ✔ Ensure that the ECU takes over the VMAX release

🔥 Tuning of the TCU (gearbox control)

  • ✔ Optimization of shift strategies for higher speeds
  • ✔ Adjustment of the transmission torque releases

✅ Which AMG models benefit from the VMAX cancellation?

Our solution is available for all current AMG models with VMAX limitation, including:

  • A 45 AMG (W177) – limited to 250 km/h as standard
  • C 63 AMG (W205/W206) – CPC-based limit
  • E 63 AMG (W213) – VMAX limitation via CPC & TCU
  • GLC 63 AMG (X253/C253) – full activation possible
  • GT 63 S AMG (X290) – electronic limit adjustable to 315 km/h
