GTC Prototype Showdown
GT Champions presents the GTC Prototype Showdown—a no-holds-barred battle, featuring the most elite hypercars ever engineered. Over six grueling rounds, drivers will face 75-minute endurance sprints where open setups, strategy, and pitstop precision separate legends from the rest. This isn’t just racing. It’s a test of nerve, mastery, and mechanical know how. Every race is streamed in stunning 1440p clarity, with commentary that captures every heartbeat of the action. Champions will claim the coveted GTC Winner’s Coin, a symbol of dominance in the world’s most unforgiving virtual arena. If you think you’ve got what it takes to tame the untamable—this is your proving ground.
