Fuel efficient driving.

That's not actually the real problem.

It's the lorry that I can quarantee will be sat "behind" you, that creates the issue.

Lorry sandwich anyone???:eek::eek:

Still bugs me tho' that folks really don't get what happens to fuel economy when you brake.
Clarkson actually got something right once when he was on that economy run on some big Audi or other, :

"never, never ever brake"

Sounds about right for muppet Clarkson, what a stupid thing to say, especially when some morons actually listen to what he says.

I agree sitting up the backside of a lorry isn't a clever thing to do.

No you wont. You end up having a crash with something as I've pointed out. If there driving a idiot/didn't see you but now checked there mirror and seen you about to go into there behind there going to accelerator away at high rate.

You've got to swerve across the road probably change a gear then accurate faster than they are then swerve back into your lane not a chance buddy.

Still changing my example to suit your argument.As i keep saying, doing what I said will 100% get the car past without crashing in this example."You saying no you won't you wil crash"is changing the example which I quickly thought of in answer to a previous post(think it was cyclonebri's).

Except that the clutch bearing argument holds no water, whenever I replace a clutch I replace the bearing aswell (it's stupid not to do this). And I have never had a bearing fail before the clutch wears out. People stand on the clutch at traffic lights all the time it's not just when coasting. Bearings are designed to long outlast the clutch pads.

The clutch plate will be wearing every time it engages,I never mentioned the bearing.Someone wanting to noticeably save fuel by habitually coasting would have to be dipping the clutch a lot to make it worthwhile.So they are shortening the life of that component proportionally.

Ok, but his point is totally valid, the best way to waste the energy you have both built up and paid for is to give it away by braking.

Of course emergencies are excluded , but that's outside this chat;)

So how do you drive down hill to a red light?

I drive down using my brakes to the red light using my brakes.

I think driving economically is not about driving perfectly (in economic terms ) but driving the most economically I can within the confines of the law and safety.

To drive down hill to a red light I try to slow down before hand and predict the lights so I arrive at the lights as the lights are changing and can then drive through retaining some momentum. Admittedly I get it wrong more often than not, but practice makes perfect.

Sometimes it's not possible to do this due to traffic conditions road layout etc, but I try where I can. Every situation/junction is different and there is no one method that fits all. I think the skill is to be able to apply a range of techniques depending upon the situation.

I agree, nothing at all wrong with that, however, as you say, not always possible.

So how do you stop your car if you cannot manage to do that?

Good question. I'm in two minds about this. If coming to a full stop then ideally brake using the engine running down through the gears to keep the engine rpm above tickover so as not to use fuel.

However I drive a cheap old French car so am slightly concerned about putting unnecessary strain on the clutch and gearbox so in reality I tend to use the brakes. Perhaps the solution is to loose most of the speed with the brakes until just above rpm tickover and then use engine braking.
