They are separate models at very different prices. The Formula Instinct is the newer F1-licensed cockpit with the X-Adapt wheel mount and Modufoam seat at $599 / £473. The Formula Intelligence is the heavier flagship at $2,149-$2,499 / £1,700-£1,975, marketed as the cockpit used by professional F1 drivers. Both are fixed single-seater rigs, so neither suits GT racing.
