This doesn't essentially mean it's a bad engine, it just doesn't have to put effort forward to get a car moving.
I nominate the 5.3 V8 GM used in the 2000-2006 GMT800 trucks.
You press the pedal down and you expect it to downshift, but it just stays in gear and pulls you up to speed as effortlessly as any motor could. And it'll just keep pulling and pulling all the way up to redline.
On the highway, its spinning at about 1600 RPM. And that's while being attached to a 4-speed transmission.
It is the definition on a lazy motor in the best way possible.
