Airbus could sell 100 or more of its newly launched A330neo planes at this week's Farnborough International Airshow, the CEO of Airbus Group told CNBC on Wednesday.
The A330neo debuted at the U.K.'s biannual airshow on Monday and the first order arrived that day, said Tom Enders.
"We are already confident at this airshow that we'll get a significant number of new orders," he told CNBC. "I would not be surprised if by the end of the week we had a 100-plus orders for the 330 neo."
The wide-body plane is an updated version of Airbus's A330 and uses latest-generation Rolls-Royce Trent 7000 engines.
Airbus claims the new plane will cut A330 fuel consumption by 14 percent, making it the most cost-efficient medium-range wide-body aircraft available.
The chief executive of Boeing, Airbus's main rival, told CNBC he was certain his 787 Dreamliner could compete against the A330neo.
"We feel highly confident in our new technology line that is already in place as it competes against a refurbished A330," he said.
In orders for the first half of this year, Boeing has taken 499 against Airbus's 290.
Deliveries of the A330neo will start in the fourth quarter of 2017. Development costs will be incurred between 2015 and 2017, with an impact of around -70 basis points on Airbus Group's 2015 return on sales target.
"It has certain costs but from a business case I can tell you, it's amazingly good and it's worth the investment," Enders said.
Passengers on the plane will benefit from 3-D films, mood lighting and full Internet connectivity.
Airbus Group comprises Airbus, Airbus Defence and Space and Airbus Helicopters. It generated revenues of € 57.6 billion ($78.2 billion) in 2013 and employed a workforce of around 139,000.
