Boeing cool on new engine for B737, doesn’t expect B787 charge on latest delay– Suppliers Share Wrap

Boeing's CFO, Jamie Bell, has admitted the company does not see new engines for the B737NG family resulting in the double-digit efficiency improvements that airlines are after. While new engines will offer a 10-16% improvement in fuel burn, Boeing does not believe that the business case for re-engining is sufficient, as the weight and design changes, and the added cost, look more likely to result in single-digit improvements. Boeing stated its customers "have not shown a real interest in a re-engining".
