Officially teased last week, the Mercedes-AMG GT3 will be unveiled imminently but these images have just popped up online via a Mercedes blog, shot at Portugal's Estoril racetrack. Based on the AMG GT, the GT3 racer will replace the SLS AMG GT3, and come with a widebody kit, more vents and an oversized rear wing. The shot of the stripped-out cabin reveals a roll cage, carbon-fiber shell driver's seat, a large digital display, a race-spec steering wheel, plenty of cool knobs and buttons and a serious chunk of carbon-fiber trim. Check back for the official unveiling any time now.
