Le G400 apporte le poste de pilotage Symmetry et l’architecture à commandes de vol électriques de Gulfstream au segment d’entrée de la grande cabine. Ayant volé pour la première fois en août 2024, il partage sa section de fuselage avec les G500 et G600 tout en visant 4 200 nm de rayon d’action avec de nouveaux moteurs PW812GA ; la certification et les premières livraisons sont attendues en 2026.
