Introducing the Porsche 963 GTP - available with next weeks Season 4 build! After a five-year hiatus from top-level prototype racing, Porsche returned to the discipline in 2023 with the all-new 963 for the IMSA WeatherTech SportsCar Championship's GTP class. Partnering with Multimatic to construct the chassis, the 963 made its racing debut at the 2023 24 Hours of Daytona with Porsche Penske Motorsport, and more teams have begun to adopt the car around the world as the season has continued. Penske's Mathieu Jaminet and Nick Tandy gave the car its first win at Long Beach in its third start of the IMSA season. Powered by Porsche's 4.6 liter, twin-turbocharged V8, the 9RD engine that powers the 963 makes over 670 horsepower. As with other GTP cars, the car weighs 1,030 kg and features a spec 50kW hybrid system.
