Why Doesn’t The Boeing 777 Have Four Engines Like The A340?
The Boeing 777 is one of the most popular widebody aircraft in the world and one of the first high-capacity aircraft to switch to a twin-engine design. Meanwhile, competitor Airbus doubled down on the four-engine A340. So why did Boeing go with two engines for its 777?

A340: 4 engines 4 long haul
This is the plane that killed the MD-11, A340, and the A380, the advantage was the twin engine, yes this was a right choice, now she’s on a heavy battle with the A350
Short answer:
The 777-300ER is amongst the best planes ever. Twin engine and can carry 300 passengers in a 4 class configuration, and 400 in 2 class
I miss the times where quadjets were everywhere
"Why doesn't the 777 have 4 engines?" Because they wanted to sell some.
imagine a 777 with 4 engines. those ge90's would roar

Don't forget, the 777 has more than proved that 2 engines can go long haul, the 777, specifically Continental's 777s, are responsible for starting the battle of longest flights.
It doesn’t need 4 engines ! The GE90 engines are one of the biggest and most powerful for the 777 . Each GE90 produces 52,000 HP, and a overall rating of 94,000 pounds of thrust ! So twin engines are plenty enough for the Boeing 777 or 777 300ER in any variant . I have flown on the 777 many times for travel and I have been impressed and comfortable every time .
Just a little correction on the orders; the original 777 has 1649 produced with a backlog of 54 to be made (37 of those are freighters) and the 777X has an actual backlog of 276, with Etihad and Lufthansa dropping their orders to 6 each, from 25 & 20. Total 777's ( all variants) on order are 330, totalling 1979.
Simply a great plane overall. I really enjoy flying in this model: quiet, smooth, reliable.
i am still a tri engine or four engine aircraft fan.
C'mon. This is an answer we all know. It's because it has
The fundamental reason the 777 and other newer twins have ETOPS ratings is that engines have evolved to a level of reliability that an inflight shutdown is very rare, and two engines shutting down within the ETOPS range is virtually unheard of. Part of the reason is that a great deal of attention is focused on eliminating common mode failures, but more generally upon the topic of “RMS” - Reliability, Maintainability and Safety engineering.
My all time favorite aircraft.
It was ahead of it's time, they had no way of guessing there would be another spike in fuel costs but it paid off big time, just look at the order numbers compared to the A340.
First! - TB
B777, B787 and A380 are my favourite ones!😍🤩
Back in the age of the 777, Boeing was the industrial visionary that demonstrated engineering ingenuity and made no compromise. What they came up with were game-changing products that would robustly serve the market for decades. Sad how they have become the profit-driven, corner-cutting corporation it has been in recent years. Hope they would learn the hard lesson and restore the craftsmanship that has been long missing.
