2021 F150 V8 will have cylinder deactivation

Recommended Posts

Unless you own one, we'd bet you didn't know that Ford's 5.0L V-8 engine used in the F-150 does not feature cylinder deactivation, until now. This technology, which Ram and GM have both had on V-8 and V-6 (GM) engines for decades, allows the engine to shut down four cylinders when full engine torque isn't needed, thus saving fuel. It remains to be seen whether Ford is using a system similar to GM's Active Fuel Management (the same four cylinders deactivate each time), which is also how Ram's system also functions, or GM's new Dynamic Fuel Management (different cylinders deactivate according to need and to spread out the wear). Either way, we're glad Ford's finally showing up to this party.

So now instead of just leaking oil from the plastic oil pan, it can blow lifters too.
