As for noise and vibration...the restart is NOTHING LIKE when you crank the car up first thing in the morning. It’s less vibration than you experience when you blip your throttle.

What a wonderfully incitefull comment. Please continue to share your wisdom with us. If you read what you quoted, which you obviously didn’t, I said that very same thing. Had the vehicle I bought had start/stop, which it doesn’t, I wouldn’t have bought it. If all the manufacturers insist on putting it on new cars, I’m lobbying for a simple defeat switch to allow the consumer to decide. I look forward to your posts later today on the China trade talks and North Korean disarmament.

Will the L3B end up in the Camaro?

He insisted on buying a GM when there are FAR better options out there for the money. Never mind the horrible dealer experience. I’m lobbying for the inclusion of defeat-able start/stop since the actual GM people in this thread seem to think it’s fine. It’s not. If it was so unobtrusive, they wouldn’t have listened to the complaints and added it for 2019. I have zero buyers remorse. My Honda is light years better than the Equinox. Again, not including a far, far greater dealer. If people don’t demand better, and hold manufacturers accountable, we get GM circa 1974. Buy our car, we know better than you, and if you don’t like it tough. We all saw how great that turned out. |

Got I it. You’re right, the BAS system that GM used on the Vue, the first Malibu hybrids and a couple other vehicles that my retired brain won’t let me remember were considered to be the smoothest restart systems on the market. I didn’t know you were a GM tech or I would not have assumed you didn’t know the difference between a hybrid and a stop/start system. Most people do not know the difference.

When I was at GM, I was one of the biggest advocates of GM adding automatic transmission stop/start (ATSS) systems to vehicles. Pressed this for years to Engineering leadership. Got a lot of pushback. When it became evident that it would be needed to achieve future fuel economy mandates and that it was one of the lowest “cost of compliance” technologies available, Engineering went at it hard and developed a configuration that works more seamlessly than any other ATSS coming to market. Engineering felt it was so smooth in operation that they would offer it without a defeat switch. I advocated against that. This is when the first ATSS applications (BMW 5-Series) were coming to market. Manual transmission stop/start (MTSS) had been in Europe for years by then. We got hold of a 5-Series with ATSS and test drove it. It sucked. We pointed that out to Engineering and they basically said “we got this”. Part of the issue is, EPA only gives partial credit for having ATSS if it can be turned off. GM had factored in the full impact / credit allowance for having ATSS. To have that credit cut in half because of a button wasn’t gonna cut it, so the focus was to make the system so inobtrusive that customers wouldn’t object. I and my team kept arguing against this approach to the point where an Engineering Director pulled me aside before a meeting on the topic and said “Look, we get it. You want the button. It’s not gonna happen, so let it go. Come to Milford Friday [before another meeting on this topic] and drive the mule.” I did. It was awesome. From that point on I and my team stood down on the topic. That is the system that launched on the Malibu. Every press review I’ve read on the Malibu talks about how seamless the ATSS is.

Here's a GM authority article on start-stop....
http://gmauthority.com/blog/2016/05/...icles-by-2020/ I agree you should do your homework on any model you are considering buying....Looking at the websites for Chevy, they aren't really advertising or announcing which models have it...I think the mind-set should be assume that it does have it unless you can research and find out it doesn't.... Again, I'll make the case for my beloved Impala, get one with a v-6 while you can...No start-stop, and it's the only Chevy sedan with a v-6...lol... |

I guess I should have also noted that most cars already have an ATSS defeat switch. It’s called Rear Defrost. On some vehicles it works every time, on others most of the time. Depends on whether ATSS is enabled by a separate battery. One of the factors that instructs the car to stop the engine or not is battery draw. If there is a significant battery draw (rear defrost and AC are two of the biggest draws) the ATSS will be bypassed. A lot of people are on to the AC, but some systems now cut the AC and then resume the AC. I haven’t seen one yet that turns off the rear defrost.
