Gunther Werks' Project Endgame: The 840-HP Turbo Speedster Built for a Private Collector

Gunther Werks unveils Project Endgame, a bespoke, roofless Turbo Speedster based on a Porsche 911 built for the brand’s eighth anniversary. It pairs a Rothsport-built 4.0L flat-six with turbochargers to produce 840 hp in a 2,600 lb chassis, making it the fastest Speedster to date. The one-off emphasizes collaboration with the client and features Marvel/Iron Man-inspired details, including a replica arc reactor and a gemstone-laden shifter, while the owner remains private.
