aria-label="21C0479 129"Mercedes-AMG has kick-started its electrified era by unveiling the new GT 63 S E Performance 4-Door Coupé as an 831bhp mega-saloon to rival the Porsche Panamera Turbo S E-Hybrid.

Based on the V8-powered GT 63 S 4-Door Coupé, Affalterbach’s first plug-in hybrid model supplements the reserves of the twin-turbocharged 4.0-litre petrol engine with a 150kW electric motor on the rear axle in a new arrangement referred to as the P3 drive system. Derived from the hybrid drivetrain of Mercedes-AMG’s Formula 1 racer, it’s said to give optimised weight distribution and the quickest possible deployment of torque.

aria-label="21C0479 130"With more power on tap than any AMG model yet produced and more than 1400Nm of torque, it will clear the 0-100km/h sprint in just 2.9sec and top out at 315km/h – effectively matching the smaller and more track-focused GT Black Series two-door launched last year for outright pace.

The electric motor takes its power from a 6.1kWh, 400V battery pack. Claimed to weigh just 89kg, this was “designed for fast power delivery and draw, not for the longest possible range”.

aria-label="21C0479 131"Mercedes claims the new PHEV will manage 12 kilometres of EV running per charge, with the electric motor capable of handling propulsion alone at speeds of up to 130km/h.

Electric power is said to be “always available”, enabling quicker acceleration out of corners or rapid overtaking manoeuvres.

Design changes over the standard car are subtle, limited chiefly to a new front bumper modelled on the two-door GT, bespoke badging, new exhaust outlets and exclusive 20-inch and 21-inch wheel designs. Otherwise, the PHEV is almost visually and technically identical to the recently facelifted regular GT 4-Door Coupé.

aria-label="21C0479 123"It’s the same story of subtle adaptations inside, but, as with other Mercedes PHEV models, there are a number of hybrid-specific displays for the MBUX infotainment system, including an EV range indicator, real-time power consumption data and an electric motor power gauge.

AMG chairman Philipp Schiemer said: “With the new GT 63 S E Performance [4-Door Coupé], we’re transporting our brand DNA into an electrified future. In doing so, we’re following our own technical path, which is what has always made AMG so special and desirable.

aria-label="21C0479 006"“Developed entirely in Affalterbach, the performance hybrid offers a fascinating level of driving dynamics and rightly bears our new technology label E Performance.

“With this new concept, we’re also opening up to new target groups who will experience Mercedes-AMG as the performance luxury brand of the 21st century.”

Pricing and availability details have yet to be confirmed, but expect a sizeable premium over the standard GT 63 S 4-Door Coupé.
