The Airbus A330neo ("neo" for "New Engine Option") is a wide-body jet airliner currently under development by Airbus from the Airbus A330 (now A330ceo - "Current Engine Option"). A new version with modern engines developed for the Boeing 787 was called for by owners of the current A330. It was launched on July 14th 2014 at the Farnborough Airshow, promising 14% better fuel economy per seat. It will use exclusively the larger Rolls-Royce Trent 7000. Its two versions are based on the A330-200 and -300 : the -800 should cover 7,500 nautical miles (13,890 kilometers) with 257 passengers while the -900 should cover 6,550 nautical miles (12,131 kilometers) with 287 passengers. The -900 should be introduced in March 2018.
