As reported by Airbus, the new A350XWB model will be 12.5 centimeters wider than the previous draft and carry 314 passengers. It will also make extensive use of carbon-fibre composites and fuel-efficient engines. The new A350XWB _ for "extra-wide body" _ will take on both the Dreamliner and the Boeing’s 777.
Airbus intends to begin development in October, and the plane is expected to enter service by mid 2012. No word yet on the rumored A370.
