Mercedes-AMG presented the AMG GT3, a race version of the GT, at the Geneva Motor Show, which employs the M159 6,208 cc (378.8 cu in) V8 naturally aspirated engine also used in the SLS AMG GT3. It consists largely of carbon-fiber-reinforced polymer to decrease the vehicle's weight to under 1,300 kg (2,866 lb) to comply with FIA regulations for races.[44] In 2016, AKKA ASP, Black Falcon, HTP Motorsport and Zakspeed compete in the Blancpain Endurance Series.
