The P1 GTR was initially only available to P1 owners. The concept car made its debut at the 2014 Pebble Beach Concours d'Elegance in August 2014.
The P1 GTR production model was officially unveiled at the 2015 Geneva Motor Show.
The P1 GTR went into production in 2015, after all the 375 standard P1s had been built, as a homage to its race-winning ancestor, the McLaren F1 GTR and were built, maintained and run by McLaren Special Operations.
