Airbus is seeking airline support for a new 400-seat jetliner provisionally dubbed the A350-8000 as competition escalates with Boeing over the world's largest two-engined jets, airline and aviation industry sources said.
After talking up the possibility of a new member of its A350 family, the European planemaker has swung into an active pre-marketing phase as it responds to a recent upgrade in the competing Boeing 777 series.
While Boeing has scored successes in the Gulf with its biggest ever twin-engined jet, the 406-seat 777-9, Airbus is expected to aim its design at airlines that do not always require the performance needed for extreme Gulf conditions.
"It would have similar capacity and range (as the 777-9) and substantially lower seat-mile costs," Airbus sales chief John Leahy said in an interview. "We are showing it to airlines right now."
The project is the latest move in a game of leapfrog played by Airbus and Boeing over the past decade in the market for big twinjets, valued at about $1.9 trillion over 20 years.
It marks a shift in priorities after the collapse in oil prices eased pressure on Airbus to upgrade its larger four-engined A380, output of which is declining because of slow sales.
Two of the airlines whose feedback could be decisive in whether Airbus launches the new jet are Singapore Airlines and British Airways.
Singapore took delivery of its first smaller A350-900 model this week and has long been weighing up the 777-9, while putting pressure on Airbus to offer it a choice.
Both airlines declined to comment.
Airbus planemaking president Fabrice Bregier was visiting Singapore on Thursday for a delivery ceremony, at which a company spokesman declined to comment.
The A350 XWB (Extra Wide Body) family was launched after a string of setbacks in 2006 to compete with Boeing's mid-sized 787 Dreamliner and the larger 777.
Boeing responded to the all-new jet by upgrading its existing 777 series to include the 777-9, which has outsold the A350-1000 by about 40 percent but has entered a lean period since its launch with big Gulf orders in 2014.
Boeing has disclosed 306 sales of 777-9s and a similar variant, while Airbus has sold 181 of its A350-1000s.
"It is clearly an airplane that is on its own in the marketplace and the airplane is selling very well," Boeing marketing chief Randy Tinseth told the Istat Americas air finance conference, referring to the latest 777 model.
The new, bigger A350 would use a derivative of the latest Rolls-Royce Trent XWB planned for the A350-1000. One person briefed on the plans said it would boost thrust from the current 97,000 pounds to about 100,000 pounds.
A Rolls-Royce representative was not immediately available for comment.
To give it more capacity and compete with the 777-9 on long trips, engineers are likely to examine design tweaks to boost the maximum take-off weight to a little more than 319 tonnes, compared with 308 tonnes on the Airbus A350-1000, the person said.
However it would sacrifice some range compared with the 8,000-mile A350-1000.
Airbus says it has not made a final decision on whether to launch the longer new plane and will provide an update at the Farnborough Airshow in July.
Meanwhile, it has been weighing up what to call the new member off the A350 XWB family, reflecting deeper decisions on market positioning that can affect billions of dollars in sales.
It needs to strike a balance between protecting sales of the A350-1000, by emphasizing differences without weakening its long-held mantra of commonality between related aircraft.
Until now, the possible new model was widely known in the industry as the A350-1100, continuing a sequence from the 276-seat A350-800 to the 315-seat A350-900 and 366-seat A350-1000.
Now, sources say it is being pre-marketed with a surprise new identity, the A350-8000, though a final decision has yet to be taken. An earlier working title was A350-1000 XL.
Leahy confirmed that Airbus was reluctant to ratify the industry's nickname of A350-1100 but declined to give details.
"You don't want it so close to the 1000 that it is an either-or decision. You have the 1000 and another airplane, with equal gaps of 40 seats between the 900 and 1000 (models), and then whatever this becomes."
Eight is a number widely used by planemakers and is seen as a symbol of success in a key battleground for sales: Asia.
"Eight is a very nice number out in Asia, but we are not going to comment until we launch the program," Leahy said.
