Based on the popular Legacy 600, the 650 will provide longer trips for up to 14 passengers with an extra 575 miles of range, while retaining the same comfortable cabin layout. The extra range allows for nonstop trips from London to New York, even with headwinds. Changes include a reinforced wing and landing gear to support more fuel weight, an extra fuel compartment on the belly, and new fuel-efficient Rolls-Royce engines. The cockpit avionics are updated to the Honeywell Primus Elite suite, which will also become standard on the 600. Upgraded insulation reduces cabin noise levels. First delivery is scheduled for the second half of 2010.
