Cars with "freewheel " like a bike.?

[xenon]

Are there cars with freewheel, it would save on gas.

[desert camel]

not sure but some 4x4's and suv's have freewheeling hubs...but not sure if thats the same.
EDIT
come to think about it,dont auto-matics freewheel?

My Dad had a Wartburg with freewheel. 3 pot 2-stroke. It cost him more in plugs than it did in petrol.

Rovers used to have a freewheel in the 1950s - but the only one i know of fairly recently was a 1976 Wartburg I owned about 10 years ago.
For those of you who've never heard of Wartburg, it was an East German car with a 3-cylinder 2-stroke engine. Sounded like the Crazy Frog and went everywhere in a cloud of blue smoke - great fun!
The freewheel was brilliant - you could change rear without using the clutch........

Some very early cars had freewheel. With a fixed drive, you get the braking power of the engine when you take your foot off the accelerator. Experience showed that this was safer.

When a modern engine is on over run ( rpm >2000 and throttle closed ) it uses no fuel anyway.
If you had a freewheel you would lose engine braking which would cause you to have to use your brakes more and wear them out quicker and since the engine would not be turned ** the wheels it would infact use more fuel ! as it would need to keep running ** itself.

So there is no point in it as it would cost more for no benefit

Edit Automatics do freewheel to an extent which is why they use slightly more fuel. But newer computer controlled automatics are better and do give some engine braking effect.

Yeah, you just keep the clutch down... I doubt there are any cars which include this as an actual 'feature', it's a bit dangerous.

I used to do it all the time when I drove. Just put it into neutral. Cant do it with automatics, which annoyed me no end
