Engines on demand

2015 f150 with four one liter echo boost engines,with common oil sump,and electric oil and water pumps to maintain engines ready and warm.this is more efficient than cylinder shutdown like gm.

An engine has around 2500 moving parts and 1 active coupling, more or less about 500 in various configurations. 4 individual engines have 10,000 moving parts with at least 4 active couplings. Failure risk in at least one engine is raised to a power of four. The legendary Ford reliability would then be hardly comparable to GM.
