The Mercedes-AMG GT3 race car has been officially revealed by Daimler after a leak overnight by a French weekly magazine.

Based on the road-going Mercedes-AMG GT coupe, the GT3 racer has been built to comply with the FIA’s GT3 racing regulations.

The Mercedes-AMG GT3 is distinguished from its road-legal brethren by a wider body finished off with enlarged air intakes, a prominent diffuser, an eye-catching rear wing, vertically slatted grille, and side exhausts. According to AMG: “every modification to the bodywork has been made for the purpose of maximising power output and aerodynamic performance”.

The road-legal cars use a 4.0-litre twin-turbocharged V8 that produces 340kW/600Nm in the GT and 375kW/650Nm in the GTS. The track-only Mercedes-AMG GT3, on the other hand, will use an updated version of the 6.2-litre V8 employed in the outgoing SLS AMG GT3.

Hooked up to the 6.2-litre V8 (which Mercedes-AMG continues to claim is a 6.3-litre engine, despite its displacement of 6208cc) is a six-speed sequential transmission, which is mounted on the rear axle.

Reasons cited by AMG for retaining the “high-revving naturally aspirated engine” include “user-friendly technology, excellent reliability, long maintenance intervals and … low running costs”.

The GT3 features an aluminium spaceframe, while the vented bonnet, doors, front and rear aprons, diffuser, boot lid, front and rear wings, side skirts and sidewalls are all made from carbonfibre.

Also fashioned from carbonfibre is the driver’s seat pan, while the integrated roll cage is constructed out of high-tensile steel.

Clad in matte grey paint, the GT3 will make its public debut on the Mercedes-Benz stage at the 2015 Geneva motor show.

The company will begin delivering the first Mercedes-AMG GT3 vehicles to teams at the end of 2015, meaning that the race car won’t see competitive action until 2016.
