driving downhill - fuel consumption

I don't think it does, you know. Nowadays _nobody_ goes very fast.

If the freewheel is disengaged, it is exactly the same as if no freewheel was fitted.

you cannot take a test in many older vehicles, in particular anything without a headrest springs to mind.

"Mrcheerful" gurgled happily, sounding much like they were saying:

Care to point us to a reference for that?

I will:

Thanks.

So it would be possible to take a test in many "older vehicles", including those with freewheels. 62mph achievable speed and a headrest seem to be the only real restrictions.

"Safer not to coast"?

Many years ago they actually made cars that would automatically disengage the gearbox as you lifted your foot off the accelerator and re-engage it when you pressed the accelerator again this allowing the car to coast whether on the flat or downhill.

They even used to use pre-engaged gearboxes as well, four wheel drive, anti-lock breaking, basic electronic controls that would 'cut' the ignition pulses that allow 8 cylinder cars to run on 4 cylinders and run cars with two-stroke engines - there really is nothin' new under the sun.

You seem to be confusing "economical" with "advisable".

heh, I missed off the " ;-) "

My bro once had a BX go "flat" on him on the motorway, reckoned it was like being in a high speed sledge with wheels :-)

I'm a Saab owner - not two-stroke of course. You can have my opinion for what it's worth though. Julian's argument is well ahead for plausibility but I'm still listening. I think we need more info on exactly how a closed throttle can lead to over, rather than under oiling.

We'd have to check that none of those cars had a separate lubrication system - later Saabs certainly did.

Cheers,

Colin.

I wonder if for health and safety they would insist the car had seat belts?

They were terrible to drive with the suspension flat, absolutely like a rock, every bump hurt you.

Not that many years ago - I was driving one in the mid 60s (1949 rover)

Ouch. Shouldn't they stay up for a while without the pump running though?

It was bad enough when the accessory belt broke on the Saab a couple of weeks ago, and all I lost then was the power steering. At least it gave me plenty of opportunity to hone my coasting-with-the-engine-off technique, but I still lost about a litre of coolant in the half a mile back to the house.

Cheers,

Colin.

They do stay up a little without the pump, unless they are totally f**cked... His was. A junction box at the back failed and emptied most of the LHM all over the place.

They're just as bad with flat spheres!

Given my experience downhill in a GSA, no, not if a hose splits.
