Well, we knew this was coming. With the recent reveals of the Panamera Turbo E-Hybrid and Sport Turismo wagon, Mercedes was never going to let Porsche steal the limelight for long. In retaliation, we got a tantalizing teaser confirming the existence of a four-door AMG GT. Now, the latest addition to the AMG GT family has been revealed in full at Geneva, and we didn't expect it to pack so much power. Simply called the Mercedes AMG GT Concept, it utilizes the same 4.0-liter twin-turbo V8 as the AMG GT coupe combined with an electric motor.

The result? The Mercedes-AMG GT Concept produces a whopping 805-horsepower. That's a lot more than the 671-hp the Panamera Turbo E-Hybrid can muster. This monumental power is derived from the EQ Power+ designation introduced in the company's Formula One car, a hybrid powertrain which will be incorporated into all future Mercedes-AMG performance hybrids. 0-62 mph takes under three seconds, which puts the Mercedes-AMG GT Concept's performance at "super sports car level" according to AMG's CEO Tobias Moers, though it can also be driven in full electric power.

It looks sublime too with an attractive design that harks back to the original CLS class, while combining the sleek looks of the curvaceous AMG GT coupe with the practicality of a sedan with its large tailgate. It also incorporates a similar active aero and cooling system to the AMG GTR, with moving radiator shutters in the center and side air intakes, as well as lightweight carbon fiber panels on the roof, A-wing front spoilers, rear diffuser and side sill and carbon-ceramic brakes complete with energy recuperation. And if you're wondering where the side mirrors are, they've been replaced with rear-facing cameras known as "mirror cams."

The AMG GT Concept may only be a concept for now, but Mercedes is planning on putting a similarly-specced model into production at some point in the future, though it remains to be seen if it takes the same design cues. It's a fitting statement for Mercedes-AMG's 50th birthday, we think you'll agree. Now we just have to wait until the Frankfurt Auto Show in September for the reveal of the radical F1-inspired Project One hypercar. Live pictures courtesy of Hampshire Photography.
