The unveiling of the GT Concept two years ago signaled a whole new approach for future high-end Mercedes-AMGs: electrification. The show car combined Affalterbach’s 4.0-liter, twin-turbo V8 with an electric motor for a total system output of 800 horsepower.
AMG boss Tobias Moers has already confirmed that in one and a half years, every AMG except for the 45-Series will get an electrified powertrain. And one of the first to head down this lane is, reportedly, the GT 4-Door Coupe.

According to Autocar, it should bear the AMG GT 73 4Matic moniker, which was recently trademarked by the automaker.
The British publication claims that spy photographers spotted a mystery prototype was driven away in complete silence, which means that it has the ability to operate on electricity alone, probably for short periods of time. When the V8 kicks in, though, the GT 73 will go from zero-emissions to full-blown bruiser in no time at all.
The top-of-the-line GT 63 S pushes out 639 PS (630 hp / 470 kW) and 900 Nm (663 lb-ft) of torque and needs 3.2 seconds to accelerate to 100 km/h (62 mph). Brabus has already tuned its V8 to 800 PS (789 hp / 588 kW) and 1,000 Nm (737 lb-ft) of torque, and they have dropped the 0-100 km/h (0-62 mph) time to 2.9 seconds. With the instant response and extra torque of the electric motor, the GT 73 should be even faster than that!
A rival to the likes of the Porsche Panamera Turbo S E-Hybrid, whose hybrid powertrain develops only 680 PS (670 hp / 500 kW) and 850 Nm (627 lb-ft) of torque, the GT 73 is expected to launch sometime next year. As for the fire power, it will be almost identical to that in the AMG GT Concept, Moers confirmed.
