I experienced this for the first time today. Not sure if I like it or not.

The car re-starts as you take your foot off the brake so by the time you press the accelerator you are all ready to go. Presumably you save a little money on fuel and 'save the poxy planet', but I can't help wondering if the constant starting will cause costly wear on components.

Anyone have any thoughts?

The manufacturer typically carry out more than 200000 starts at a raft of different temperatures so durability should not be a concern.

It seems dangerously slow and pointless. Only serves to lower a cars VED, and benefit the manufacturer in do so, and also in spare starters and batteries. Face it, it can't be good for an engine and they don't care about the car out of warranty! I'd opt out of it.

This system is, in principle, exellent.
However, it has one major flaw.
By keeping your foot on the brake, at traffic lights or in stop start traffic, you blind the driver behind you with three powerful brake lights.
Some cars seem to be brighter than others but in any case it is very distracting from behind.
On my way home last night, and on other occasions, I had to lower my sun visor to block out the glare.

TBH i would have thought the larger battery and alternator would offset some of the fuel saved if not all of it as you carry that weight all the time ?

Disable it at the start of your drive, it's what I do in the cars at work.

It's a marmite addition to a car IMO. Some will like it and use it, some hate it and will de-select it everytime they drive off. I sometimes leave it on, but I do for the benefit of cars sitting behind me, put the person into park and take my foot off the brake pedal.

The one I drove wasn't like that. The car only stopped when put into neutral and foot taken off clutch. Restarted when your foot was put back on the clutch to engage gear.

I assume the cars are designed to cope with it.

My car has it but it rarely works, but when it does its surprising how often I do use it. My system is one that doesn't need a foot on the brake to switch off so I'm not blinding people behind me.

Automatics behave as described above. Manuals as you have described.

I tried stop-start for a bit, and came to the conclusion that it's a fking awful device.

Having to disable it every time you use the car is a bit of a ball ache. Surely you should be able to on a permanent basis.

funny how much non sense people talk on this issue
just because your dad's cortina used to go through starter motors every few years, and needed a new battery every winter, does not mean the concept of stop start is flawed or bad for your engine

This. Sister's Golf has s/s for a few years now and it's never failed once, nor has the battery or anything else.

I think it very much depends on your journey. The last part of my commute home generally sees me sitting in the kind of stop/start traffic that would see the stop/start doing its thing every time I stopped for 5 seconds. In that situation, I tend to turn stop/start off. Other times I leave it on. e.g. when I can see the lights have just turned red on a set that seems to take a while to change. Yes, it's an extra thing to control, but at least the option is there.

Many a Smart Mhd driver will attest to the fact that this delightful system is highly likely to leave you at the side of the road, steam pouring out of a fubar'd engine.

The 5 series I drove recently didn't work like that - when coming to a complete stop the handbrake applies automatically, so no brake lights showing. To start moving again, just press the accelerator - whilst there is a delay to get started an moving, it's very small

I have the system on my MINI. I find when it works, it is not obtrusive. I reckon the manufacturers probably have more data about its reliability and effectiveness than neigh-sayers on the internet! Hence why they have been installed in many cars.

I also had the fore runner to the system on my 1987 VW Golf. It was a little more intrusive than the modern systems. Every time I came to a rest (at a junction, roundabout, in traffic etc.) the engine would cut out, but I would need to use the starter motor again to get it going. Even back then the starter motor or battery did not fail smile
