Will they improve the Auto start stop?

So I've used the auto start stop in the cars I have test driven and the auto start so far I've noticed is a little rough, but does it get better after the break in period? But thats not why I'm posting this do you think within the next year or so BMW will make the Auto Start Stop smoother? I have a friend, who just picked up a c350 sport and granted it's a nice car but that's the only aspect that I can see that clearly is better than what BMW offers. Or do you think they will not fiddle with it again until the LCi facelift of the F30 in a couple years or possibly later?

If it can be fixed via programming then it won't be all that long I suspect. (of course you have to factor in the cost/benefit ratio). If it's a hardware change then really it could be any time. Again assuming BMW thinks it's not up to "par".

Any reply will be entirely speculative.

Mercedes' system is far superior - annoyingly! Their ASS works out where the piston's are in their stroke and simply fires them with a quick turn from the starter to get it going.

To be honest, I think all the systems are floored because they use the starter motor, and the starter motor is old technology! It's slow, noisy, rough and really needs to be binned in the favour of something more advanced!

I know a company called CPT - Controlled Power Technologies who offer a product called SpeedStart®.

You can see the interesting technical bumf here on CPT's website, but in essence, it's an electric motor which starts the engine very quickly and very quietly. And most importantly, it reacts very quickly to driver request on reboot.

Does it even use the starter? In the cars I've driven and been driven in, I can't detect any starter action on restart.

Pretty similar to how a hybrid restart the engine.

I can't wait to reprogram my car and get rid of ASS. I forgot to turn it off the other day and thought I stalled the car and hit the start/stop button and wound up shutting it down! What a pain in the ASS. It's gotta go.

I think it is already improved from 2012 model to 2013 model. When I test drive the 2012 model the ASS was shaking the car at stop and also start. I can`t say it is very smooth in 2013 model also but it is not annoying. You feel the stop and start little bit. Moreover, it is very responsive, once I was stopped for a U turn and just took my foot of the break when the ASS shut down. The engine started again before the needle reached the ready position.

When you stop lfor a ong time when the AC running the engine starts without removing the foot off the brake. This is start is usually rough.

But I still don`t want to use it with AT because it stops everywhere, U turns, stop signs etc. I think ASS is better for an MT

It's the worst feature on Earth, eventually it's going to get someone killed and then it'll make national news and the fun will start.

At the very moment you need dependable acceleration the most, like turning left across a speedy intersection from a stop, the engine shuts off. And you work out the timing and find the right window to make your move and there's no power for a long second. Then you pray the thing starts but by the time it does your window has rapidly closed. It's a terrible experience.

Then there are stalls. Happens frequently for no apparent reason. As you say, sometimes you think you've stalled so you quickly hit the button and that turns the engine off, not on.

I couldn't let my wife drive the car until I had ASS deactivated. I hadn't been driving a car that stalled since my 1980 Honda Prelude until my 2013 BMW. And for what? So some tree-huggers can claim they're environmentally "friendly" as they drive their excessive luxury cars and smoke cigars? So someone who can afford a $50,000 German sport sedan can save $0.19 cents per fill-up?

Awful idea, awful implementation, awful choice of car to put it on. If we wanted a Prius, we'd have bought one.

I like the feature, and have never had an issue where it malfunctioned or stalled on me.

"Stalling" is beyond rediculous in the 21st century. The FATHERS of some of the people on this board are too young to remember being in a stalled car...

Next time you are at a stop or when you dont want the ass to initiate, you can trick the car by either putting the lever into DS before you come to your stop, or modulate the brake pedal and it wont activate ass

I have only had my 2013 335xdrive for 1 week (August build) but so far I like the ASS and have no problems with it. The starting and stopping is pretty subtle and as soon as I take my foot off the brake the car starts up immediately. I think for driving in the city the gas savings can be pretty significant......Maybe it has been improved and reprogrammed from the 2012 models??? I also have read some reviews where the test drivers have said the ASS in the 335i model is smoother and less harsh than in the 328i model.

Mostly I turn off ASS. I prefer to decide myself to use ASS depending of traffic situation. The currently built in ASS looks to me an intermediate solution and at least I hope that the hybride tech would be commonly used in the future. (No startmotor needed resulting in a very smooth start or restart).

We've already been there and beaten this to death. There are some very ill-informed, ignorant and down-right idiotic people over the pond who think that their narrow view of what a BMW should be should dictate a global brand like BMW. Thankfully they're the minority, not only in the world but even in their own country

For the rest of us who live in the real world, thank God BMW are implementing features like ASS to stop a completely unnecessary waste of fuel when a car is standing still.

wow yea this got a little off topic but it's good to see that some people had ASS get better with time. And it was one of the first MY2012 328i I drove so maybe that's what the issue was. I'll probably go test out that feature at another dealer on a 335. Thanks for all the feedback.

There's an article in the June 2012 Road & Track that discusses various stop/start technologies and the system BMW uses is pretty old school. Until they change the technology, I don't see the ASS becoming as good as some other vehicles.

Just want to point out that not everybody in the US is ill-informed, ignorant and down-right idiotic. In fact, a lot of us like the technology.

I feel like if you just release some pressure off the brake just before you want to get going and let the car start before you let of the brakes completely the A.S.S is much smoother. I have no problem at all with it. I even select Eco Pro when driving in the city, even though I own a 335!
