It allows the wheels to keep spinning forward when the engine slows
down, much like the rear hub of a bicycle lets you keep rolling
forward when you stop pedaling. The premise was that it gave you
better mileage. But it provided no engine braking and would
seemingly place higher demands on your brakes.
The last car I knew of which had one was the Saab 96, I think.
Touble was, the V4 engine had so much torque it tended to break the
freewheel, after which the car wouldn't go at all.
I believe freewheels were outlawed on new cars in the US by the feds
in the late 60's or early 70's.
