Airbus Acj319 vs Gulfstream G400

The Airbus ACJ320 and Gulfstream G400 sit in different business-aviation categories. The ACJ320 is a VIP airliner based on the A320 family, typically operated as a “bizliner” with a large-cabin, multi-zone interior and airline-style systems. The G400 is a purpose-built large-cabin business jet designed for corporate and private missions with a more traditional executive-jet layout and operating profile. In range, a typical ACJ320 configuration can offer roughly about 6,000 nautical miles (depending heavily on configuration and options), enabling long intercontinental missions. The Gulfstream G400 is marketed around about 4,200 nautical miles, aimed at robust transcontinental and some transoceanic city pairs. Passenger capacity differs substantially. An ACJ320 can be configured to carry far more people than a business jet—often arranged for roughly 20 to 50 passengers in VIP comfort, with maximum capacity much higher in airline layout. The G400 typically seats around 10 to 16 passengers, prioritizing comfort, baggage, and performance over high headcount.
