Mercedes AMG-GT4 PHEV charging cable

The Mercedes-AMG GT 63 S E Performance is a four-door high-performance coupé built on a P3 hybrid architecture, pairing a handcrafted 4.0-litre twin-turbocharged V8 at the front with a permanently excited synchronous electric motor on the rear axle. Combined system output is 831 hp and 1,400 Nm of torque, delivered through a 9-speed AMG Speedshift MCT transmission and AMG Performance 4MATIC+ all-wheel drive. The 0–100 km/h sprint takes 2.9 seconds and the electronically limited top speed is 315 km/h. An F1-derived 6.1 kWh battery with 4.8 kWh usable capacity powers the rear motor, designed for high power density rather than extended electric range. The WLTP electric range is approximately 12 km (7 miles) at up to 130 km/h in all-electric mode. The Type 2 charging port is integrated into the rear bumper, to the right of the number plate. The onboard AC charger accepts 3.7 kW on a single phase. There is no DC charging capability.

Charging from a wallbox

At 3.7 kW, the GT 63 S E Performance charges its 4.8 kWh usable battery from empty to full in approximately one hour 20 minutes. In practice, the battery is frequently partially replenished through regenerative braking during driving, so external charging from a fully depleted state is less common than with a larger PHEV. A standard single-phase wallbox or public AC charge point covers all charging requirements for this car.

Picking the right cable

The GT 63 S E Performance's 3.7 kW single-phase onboard charger is natively capped at 16A on one phase. An 11 kW three-phase cable delivers 16A per phase and will feed this car its full 3.7 kW without restriction, so it is technically compatible. However, an 11 kW cable is not the recommended choice for a garage that also includes or may in future include a 7.4 kW single-phase vehicle: on any standard single-phase 32A home wallbox, an 11 kW three-phase cable is limited to 16A on one lane = 3.7 kW, bottlenecking a 7.4 kW car to half speed. A 22 kW three-phase cable, with conductors rated at 32A per phase, carries the full single-phase load at 7.4 kW and reaches 11 or 22 kW at three-phase public posts. For the GT 63 S itself today, and for any future vehicle in the household, the 22 kW cable is the more practical long-term choice.

Length: finding the right fit

A 6-metre cable suits most home wallbox installations, providing comfortable reach from a wall-mounted charger to the rear bumper port without leaving excess cable on the ground. For public charge points, where the orientation of the parking bay relative to the charge post can vary, an 8-metre cable allows connection without needing to reposition the car.

Portable charging with a CEE charger

The Voldt® portable CEE charging cable is a practical option at any location with industrial CEE sockets, including trackday venues, events, and worksites. The onboard charger is rated at 3.7 kW single-phase and draws from one phase only regardless of socket type. All three CEE socket types therefore deliver the same 3.7 kW to this car, completing a full charge from empty in approximately one hour 20 minutes in each case. On a standard domestic socket at 2.3 kW, a full charge takes around two and a quarter hours, making the household wall plug an entirely practical everyday charging method for a battery of this size, whether at home, at a hotel, or in a track paddock.
