Mercedes-AMG has provided the first glimpse of a four-door version of its GT performance flagship, with a public debut of the new model in concept form to take place at the Geneva motor show this week.
A 14-second video released by the German brand overnight shows flashes of the GT Concept's coupe-style side profile, LED headlight cluster and lower front air intakes with vertical slats, as well as Mercedes-AMG's now-signature Panamericana grille.
Released alongside the footage was a sketch which also reveals two-tone copper and silver wheel rims, 3D-style LED tail-lights, a carbon-fibre rear diffuser and a single central exhaust.
Significantly, traditional door mirrors have have been substituted for cameras and are visibly branded with the words 'EQ power' – a term Mercedes uses to identify its electrified models, which suggests that the four-door GT is likely to feature a hybrid drivetrain.
The manufacturer has stated in the past that it is working towards an electrified future, which will soon be seen in its Formula 1-based Project One hypercar which pairs a 1.6-litre V6 engine with two electric motors for an alleged combined power output of at least 745kW.
The exact engine employed by the GT Concept remains unknown, but the carmaker's most powerful hybrid is currently the plug-in 500e variant of the GLE and S-Class ranges, which couples a 245kW 3.0-litre twin-turbo V6 petrol with an 85kW electric motor for total outputs of 325kW/600Nm.
Alternately, the current GT Coupe and Roadster line-up offers three states of tune for Mercedes-AMG's 4.0-litre twin-turbo V8 petrol engine - 340kW/600Nm (GT), 375kW/700Nm (GT S) or 430kW/700Nm (GT R) – any of which could be used in a non-hybrid version of the new model.
As previously reported, the new performance model is expected to be named GT4, which is a nod to its two-door namesake and four-door bodystyle.
Affalterbach's latest sportscar is expected to go head-to-head with the Porsche Panamera, which shares its long, sloping tail end styling with the GT4.
More information on the GT Concept, including powertrain details, will be revealed at the Geneva motor show, which starts tomorrow from 5pm AEST.
