2021 Porsche 911 GT3 Cup: Ready for the checkered flag Alvin Reyes - Dec 14, 2020, 5:29am CST German automaker Porsche has finally unveiled the production specs of its newest 2021 Porsche 911 GT3 Cup. The Cup version is the nastiest 992-series Porsche 911 to date, and it’s the first make-cup racer from Porsche to have a wider turbo-spec body. “The 911 made history as the baseline model for the Carrera Cups and the Porsche Mobil 1 Supercup – no other racing car has found as many satisfied customers since 1990 as the 911,” said Michael Dreiser, Director Sales Porsche Motorsport. “The new 911 GT3 Cup will shape the face of our customer sport commitment around the world.”
