The 911 GT America was based on the 991 GT3 Cup. It was built exclusively for the United Sports Car Racing (USRC) series and its GT Daytona class for 2014. While the GT3 Cup had a 3.8-litre engine at the time, the GT America was fitted with a 4.0-litre unit developing 351 kW.

The main visual difference is the rear spoiler made to fit the USRC rules. Like the GT3 Cup, the GT America has 380 mm steel brake rotors at the front axle with 6-piston aluminium fixed calipers. The rear axle features 4-piston brake calipers. The gearbox is a 6-speed sequential unit with pneumatic paddle shift system.
