History and trivia
The 911 GT1 was born in the mid-1990s as Porsche's answer to the new GT1 category, which required a road-legal version of the race car to be homologated. Unlike rivals that started from an existing road model and turned it into a racer, Porsche reversed the process: it first designed a racing prototype using a 911's front end grafted onto an entirely new mid/rear-engined structure, then built the small number of road-going units needed to satisfy the homologation rules.
In 1998 the 911 GT1 took overall victory at the 24 Hours of Le Mans, driven by Allan McNish, Stéphane Ortelli and Laurent Aïello, closing out the era of GT prototypes built around road-car homologation before regulations shifted toward pure LMP cars. The road-legal version, known as the "Straßenversion," was built in around twenty units — essentially race cars with license plates — and today ranks among the most sought-after and valuable Porsches among collectors.
