Exactly, just gearing. But you should not be using your engine to brake, that's why we have those big brembos
Computer algorithm that doesn't close the throttle completely. Engine braking doesn't help fuel economy. It also makes a car with lots of power and torque difficult to drive smoothly at times.
It certainly does help with fuel economy because the car enters DFCO.
just about every time I take her out, I'm always on the search for nice country back road lots up ahead view and long fence lines. Living in the country helps but poor road conditions is biggest problem. Many of roads have divits. Comes from when two lane roads were widened, poor foundation lets outside edges settle unevenly. Anything over 110 throws you around violently in car. Suspension handles it ok, but I don't. Most times I drive down middle of the road. Especially at night, armadillos, possum, turtles, gators, deer, coons are biggest hazard. Even had vulture shit on me one evening as he was straining to get some altitude!
Thats not close to the same thing. Engine braking and a mechanical overrev are completely different things. Engine braking has no side effects whereas the other can destroy your engine.

I know a guy who bent a valve changing to second from 5th at 100 mph. Engine caput.
It was by mistake but that's what engine braking does (ok, that was extreme, but just sayin).
The question was answered by Hack already.
To help emission and smoother throttle transition.
