Jet engine makers battle over performance

Engine makers for next-generation Airbus and Boeing narrow-body jets stepped up their war of words on Sunday, claiming their new power plants will burn less fuel than current models plus last longer without maintenance and create less noise than their rival’s.

CFM International, the engine maker for about three-quarters of the orders for next-generation Airbus and Boeing narrow-body jets, said its LEAP engine will deliver 15 per cent lower fuel burn and 2 per cent to 3 per cent lower operating costs compared with comparable current engines.
