Not sure if I could live with start/stop going on and off all the time. I was riding once in a Audi Q5 diesel, at the light one day the car just shut off as the driver tried to go. Was very strange. Say there looking for answers as everyone ahead of us just went through the advanced green.

 

Start stop in my E is pretty jarring. I recently rented a lincoln MKZ and even with a 2.0 4 cyl, the SS system was barely perceptible. However, Im fine with it in my car and found a good work around. IT does not activate when you come to a complete stop, but depends on brake pedal travel. So if I know that the light will turn green very soon, I simply do not push the brake pedal down to the floor. Holding it at mid travel doesn't to activate the SS system. This is brilliant.

 

If the system is designed correctly (and most of them are, especially the newer ones), the engine will re-start immediately as the driver's foot lifts off the brake pedal. With the new Lacrosse, it is so seamless that you don't actually feel anything at all.....you just hear a VERY faint click as the pressure-accumulator in the new 9-speed transmission (one of 60 new patents that GM and Ford have on jointly co-developing the transmission) does its thing and re-connects to the engine.

Like you, though, if I had a choice, I'd turn it off, simply to prevent needless wear on the unit in dense stop and go traffic (I'm not so poor that I can't afford a little drop in gas mileage). Still love the car, though, even with that and one or two other idiosyncrasies.

 

Is E63s out yet? I went to the dealership yesterday wants to test drive, but the sales said they don't have them available yet :/
