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 201bhp 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.

With more power on tap than any AMG model yet produced and more than 1033lb ft of torque, it will clear the 0-62mph sprint in just 2.9sec and top out at 196mph - 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”.

Mercedes claims the new PHEV will manage 7.5 miles of EV running per charge, with the electric motor capable of handling propulsion alone at speeds of up to 81mph.

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

Regenerative braking features with four levels of severity, enabling one-pedal driving in certain driving situations.

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 20in and 21in wheel designs. Otherwise, the PHEV is almost visually and technically identical to the recently facelifted regular GT 4-Door Coupé.

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. 

"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."

The new model is projected to achieve 32.8mpg on the WLTP combined cycle while emitting 196g/km of CO2.

Pricing and availability details have yet to be confirmed, but expect a sizeable premium over the £141,855 commanded by the standard GT 63 S 4-Door Coupé.

Weight wise it's about the same as the Panamera Turbo Hybrid - 2350kg.    I don't think this car is a comparable to the Porsche - the Merc is a pure performance car whereas the Porsche was designed with a less focused brief - it tries to be a lot of things.

When I heard Porsche were working on their Project Lion concept I was really hoping it would be a response to this car as it's specs have been know fir a while - I would love to see Porsche show what they can do in this space - currently the non hybrid Turbo S is the faster car.

hats off to AMG - they have made a statement car, now it's upto BMW and Porsche, perhaps Audi to respond

@ P-Cuckold: Good point. Presumably anybody who buys this car will die because driving a car is incredibly difficult.

Just Saying 1 September 2021
I remember not so long ago a 0-60 (62kph) in under 5 seconds would be a headliner. Now, accelerating in under 3 seconds seems to be manufacturers new mission.
How times have changed. Lol.
