Is It True That The Airbus A380 Uses The Same Engines As The A340-600?

It is a common myth in the aviation industry that the Airbus A380 uses the same engines as the A340-600, usually because both are four-engined Airbus widebodies and both have Rolls-Royce Trent badges in some configurations. In reality, the A340-600’s long-haul performance was built around the Rolls-Royce Trent 500, which the manufacturer developed specifically for the A340-500 and the A340-600, with different thrust ratings available for each aircraft variant. The Airbus A380, by contrast, launched with two different powerplant choices, ranging from the Rolls-Royce Trent 900 to the Engine Alliance GP7200, a GE-Pratt & Whitney joint program.
