What Is the Central Coolant Hub in the 2027 Mercedes-AMG® GT 53 4-Door Coupe? 

The 2027 Mercedes-AMG® GT 53 4-Door Coupe packs serious electric performance, but keeping that power ready requires smart thermal management. So, what Is the Central Coolant Hub in the 2027 Mercedes-AMG® GT 53 4-Door Coupe? Mercedes-Benz of Arrowhead in Peoria, AZ, can point to the Central Coolant Hub, or CCH, as a key part of the vehicle’s advanced cooling system.

What Does the Central Coolant Hub Do? 

Think of the CCH as the traffic controller for the GT 53’s cooling system. 

This compact unit brings together pumps, sensors, and valves in one integrated housing. Rather than sending cooling capacity everywhere at the same rate, it can direct coolant where it is needed most. 

That matters when temperatures climb or the vehicle is delivering high output.

How Does the CCH Manage Different Components? 

The clever part is its ability to respond to changing conditions. 

If the battery is already sitting within its preferred temperature range, the CCH can direct more cooling capacity toward components such as the electric drive units and Onebox. 

During demanding driving conditions or in hot weather, the system can increase the cooling of the vehicle’s major components.  

A large cooling circuit works with intelligent valves, a cooler, a main radiator, and auxiliary radiators to manage heat efficiently.

Why Is Cooling Important for EV Performance? 

The 2027 Mercedes-AMG® GT 53 uses an 800-volt, 106-kWh usable battery with directly cooled cylindrical cells. Keeping those cells within their preferred temperature range supports strong charging and power delivery. 

The battery contains 2,660 cells arranged across 18 modules, with electrically non-conductive oil flowing directly around individual cells for targeted temperature management. 

The result is a sophisticated system built around one simple idea: control heat intelligently. 

With up to 600 kW DC fast charging at compatible 800-volt stations, thermal management becomes especially important. The CCH helps the GT 53 handle demanding charging and driving conditions while directing cooling resources where they can do the most work.
