ACC Stop + Go, did I miss much?
 

Configured a new 2015 F15, skipped the ACC Stop + Go option. Now that the vehicle is in production, I can not add or modify anything.
Anybody with that option can tell me if I missed a lot on this one?

not sure if this is the same thing - on my wife's 335 there is a feature, when the car comes to a stop, the engine shuts off... the moment you let the foot off the brake (even move the foot a bit), the engine starts up... at first, it was scary, felt like the car stalled, but later it became "normal"... you can turn it on and off...

very nice on the economy - much thriftier than the previous year 335 that she had...

if we are talking about something else, then - sorry dude...

That is Automatic Shutoff and Start, known for short as ASS.

ASS... ACC...

so, what ACC does?

I have ACC on my new Mazda 3 and it is a great option for those who frequently drive highways and are used to using cruise control in the past. The technology has evolved so that the whole "Control" is much smoother.

Last weekend, I tried this out on a derestricted stretch of freeway and set cruise at 140km/h (87mph) and the 2/4 distance setting. As I approached a vehicle doing 120km/h (74mph), I deliberately stayed in my lane. The vehicle let off the throttle, then gently braked down to match the vehicle's speed. After a little while, I changed left and the Mazda accelerated (smoothly) back up to 140km/h. I even tried this in an urban area, obviously at a slower speed setting, and it worked great. As good as a human driver. Makes long-distance driving quite easy. With the more advanced systems on the BMW, the Stop & Go will bring the vehicle to a standstill if you approach stopped traffic.

That said, if you don't do a lot of highway driving and/or don't use cruise control normally, the benefits are more muted.

ACC = Active Cruise Control with Stop and Go function.

I have the ACC. I got it because I do a lot of highway driving. It is great. It's got some pretty slick software that analyzes other cars distance and speed in front of you and varies your speed to keep a semi-constant distance. I say semi-constant because it's smart enough to know when a car is accelerating away from you or decelerating toward you and applies brakes/gas accordingly. You can set the distance you want to maintain (4 different ones). I use it so much I had the car coded to default to the shortest distance as opposed to the longest, which is factory. It's the most advanced cruise I've ever seen.

BUT, if you don't do a lot of highway driving then it won't get much use.

EDIT: oops. I do not have the stop and go. My bad. I just have the ACC with distance control

ACC + Stop and Go basically can bring the vehicle to a full stop while cruising and then can resume forward move when the vehicle in front starts moving again.

Also ACC + Stop and Go is required (this is vague but that's the understand users got from recent forum posts) in order to have City Collision Mitigation to apply brakes and stop the vehicle for you. Otherwise Driver Assistance Plus (DA+) will only prime the brakes while giving you audible and visible warning.

Did you miss a lot? I don't think so unless you drive long distances on a daily basis and you really relied on your vehicle to keep you moving. In my opinion I probably wouldn't rely on ACC's Stop & Go function very much even if I had it.

If your stuck in traffic crawling all the time its not a bad feature, I don't mind it.
