The private jet world just got a shake-up.
Gulfstream has pulled the covers off its brand-new G300, a super-midsize jet designed to replace the long-running G280.
The reveal happened this week at the company’s Discover the Difference event in Savannah, Georgia.
And while it’s still only a mockup, the promise is enough to get rivals watching closely.

Gulfstream reveals the G300
The G280 has been the company’s workhorse since 2009, with around 300 units delivered.
But the G300 is built to take that legacy and push it faster, higher, and further.
It’s powered by a pair of Honeywell engines – Gulfstream’s keeping the exact spec under wraps – but the performance figures speak for themselves.
At full tilt, the G300 runs up to Mach 0.85, or 652mph.
Ease it back to Mach 0.80 (614mph), and it will stretch a range of 4,143 miles.
That’s continent-crossing territory without breaking a sweat.
Its ceiling sits at 45,000 feet, and with a cabin altitude of just 4,800 feet, passengers feel fresh instead of fried at the end of a long haul.
Up front, the Harmony Flight Deck is Gulfstream’s latest cockpit system.
Six touchscreens, built-in ‘Phase-of-Flight’ smarts, synthetic 3D vision of terrain, and a predictive landing system that shows exactly where the jet will stop on the runway.
It’s the kind of kit designed to keep pilots ahead of the jet rather than chasing it.
Right now, only one test aircraft exists, with two more in build.
Even so, Gulfstream says it’s already clocked 22,000 hours of testing on the ground and in systems rigs, plus 2,000 hours of actual ground runs.
No date yet for the first flight… but the direction is clear.
Flying private for 10 in pure luxury
Where the G300 really flexes, though, is the cabin.
It’s the longest in its class, ringed with 10 oval windows to flood the interior with light.
The company designed it to carry up to 10 passengers, with sleeping space for five.
The layouts are flexible – you can split it into two living areas, opt for a divan with gold-and-tan throw pillows, or fit deployable tables for working lunches.
The whole environment is wrapped in a plasma ionization purification system, so the air feels clean and fresh instead of recycled.
Combined with that class-leading low cabin altitude, it’s built to keep jet lag at bay.
The pitch is simple: speed gets you there, but comfort decides how you arrive.
That’s the real message behind the G300.
A jet quick enough to keep pace with the competition, but indulgent enough to remind you that this isn’t commercial air travel.
It’s private flight done Gulfstream’s way.
Because in this game, it’s never just about miles per hour.
It’s about the miles you spend inside.
