Autocar reports that BMW plans to launch its Automatic Engine Start/Stop System next year - one of the fuel economy and emissions reduction components of its "Efficient Dynamics" technology package, as the company aims to meet its commitment to the European Association of Automobile Manufacturers 2008 CO2 emissions reduction targets.

Officially called "Auto Start/Stop," the system automatically switches off the engine when the car comes to a standstill. As soon as the driver puts in the clutch or depresses the gas pedal, the engine restarts automatically. BMW's "Intelligent Software" links together the various sensors required with the starter motor and the alternator control to make the process work.

Auto Start/Stop, along with BMW's High Precision Injection (lean-burn direct injection) and Brake Energy Regeneration technologies, will appear across a broad model range, with the Start/Stop technology to be introduced in four- and six-cylinder 1-, 3- and 5-Series models.

Like we don't have enough electrical problems as it is. Cars stalling, hitting the gas too hard, not hard enough. Bad sensors, I see all kinds of issues right now.

do we burn that much gas just sitting there?

interesting. although, i thought that
starting the engine was what caused
the most damage to engines.

Sounds aweful to me - I really hope that doesn't happen or at least make it an option.... Yuk.

Seems it will be part of the "Efficient Dynamics" package.

There was a study that showed starting a stoping a motor used more gas then sitting at idle...that was ten years ago though...tech might be better now...wow I hope that is option that you can refuse.

Good idea, as we get Zero mpg while sitting, idling.

Really effective if the "sit" is for more than 20-30+ seconds, I have read.

Doubt it has any negligable effect on "start up", when fully warmed, as the oil drain in theses suckers is slow.

As for the glitch potential: ah, what's another glitch?!

Does the car go into park when the engine turns off? I seems that it would be a little too invasive, but I guess we'll have to wait for the technical descriptions.
