Boeing 7E7

Boeing engineers are using a 7E7 concept design to push their thinking on more innovative exterior designs concepts including a refined nose shape, new wing tip concepts and a sculpted vertical tail structure. Engineers are studying these touches for consideration on the new 7E7, which is being designed as a super-efficient, twin-aisle airplane capable of carrying 200-250 passengers on long-range routes.
The 7E7 will carry 200-250 passengers on routes between 7,200 and 8,000 nautical miles (13,334-14,816 km).

In addition to bringing big-jet ranges to mid-size airplanes, the new airplane will provide airlines with unmatched fuel efficiency, resulting in exceptional environmental performance. The airplane will use 15 to 20 percent less fuel for comparable missions than any other wide body airplane. It will also travel at speeds similar to today?s fastest wide bodies, about Mach 0.85.

Passengers will also see improvements with the new airplane, from an interior environment with higher humidity to increased comfort and convenience.
