To close out 2021, Gulfstream has added a new small aircraft model to its business jet lineup. The plane is called the G400, and it slots between the entry-level G280 and the best-selling G500.

Gulfstream’s marketing material touts the efficiency of the G400. The plane’s range is an impressive 4,200 nautical miles at Mach .85, and it can reach a maximum speed of Mach .90. The G400 cruises at up to 51,000 feet.

The G400 can accommodate up to 11 passengers, and it sleeps 4. The cabin design favors low noise, light and air quality: the model features plasma-ionization air purification that replenishes the air every two minutes, and it is fitted with ten large windows. It can be customized with up to 2.5 separate living areas for work, sleep and meeting space.

Like the G500, the G400 is powered by engines made by Pratt & Whitney—in this case, the PW812GA. The PW812GA’s design and materials, according to Pratt & Whitney, deliver substantial improvements in fuel economy, emissions, ambient cabin noise and maintenance needs.

The G400 is outfitted with Gulfstream’s Symmetry Flight Deck, which features touch-screen displays, Phase-of-Flight intelligence and active control sidesticks. The model also comes with the company’s Predictive Landing Performance System.
