Three cars will start the 2017 season, two of which will be fielded by Riley Motorsports. One of the Riley cars is partially sponsored by Mercedes-AMG, while the other is fully sponsored by WeatherTech. The third car is a customer car, and will compete under the banner of SunEnergy1 Racing. All teams running Mercedes-AMG GT3s will have support from Mercedes. The company will be able to supply parts from its headquarters in North Carolina. Not only that, but Mercedes will deploy a team to each race event to provide help and support.
Because the AMG GT3 will be competing in the GTD class, it will be facing many European rivals from Aston Martin, Audi, BMW, Ferrari, Lamborghini, and Porsche. This past year, a few Dodge Vipers also took to the circuit. The AMG GT3 won't be directly facing off with the Ford GT and Chevy Corvette, though, since those two compete in the GT LM class.
