ACC Stop & Go
 

My car, a 35d, arrived at the dealer today. I ordered it pretty much loaded with everything except for a few options. It stickers at $86,500. I asked for the VIN # and was given the order sheet which totaled $85,300. So something was missing and it is the ACC Stop & Go.

I've read a few threads on other forums and there seems to be a fair number of opinions ranging from; I will not have a car without it, to, I have it and don't use it to, I really like it but could live without it.

Since this is my 3rd X5, I am finally in a position to get the one I always wanted. It also is an outrageous amount of money for a car, and as is my wont, I flipped flopped from excitement to buyer's remorse. I now have an opportunity to walk away and wait till a 2016 model which is probably only 6 months away. I am leaning towards that unless the ACC can be retrofitted which I do not think is possible (and would rather not have a dealer do even if it is)

Anyway, if anyone is in the market for a Glacial Silver w/Mocha X535d, I know where one is and it is available immediately.

That sucks. I would wait and reorder and get it with ACC stop and go. Love it the function. Also, won't get another BMW without HUD as well.

The stop/go function is horrible. It'll save you a few pennies in fuel but cost you a ton when you have to replace your prematurely failed starter. Whenever I hear someone's car star up at a traffic light, I assume that person doesn't have a clue

Also, the diesel model hardly burns fuel while idling. I actually get good mileage in mine even in stop and go traffic

Wouldnt frequent starts hurt a diesel excess wear on glow plugs ,pre heater module and soot deposits in the dpf etc?

...I know this reply is over a year later and after over 3900 views...I find it hard to believe that NO ONE has mentioned that the stop/go feature you're referring to has nothing to do with the ACC stop-n-go the original poster was referring to. :)

The OP was referring to ACC (active cruise control) with stop & go...see the explanation of this option below:

Active Cruise Control with Stop & Go function
Relaxed driving even in heavy traffic: Active Cruise Control with Stop & Go function keeps you at a constant distance from the vehicle ahead at all times. If the traffic comes to a halt, the system applies the brakes until the vehicle comes to a standstill and then automatically moves on as soon as the road is clear.

Active Cruise Control with Stop & Go function was primarily developed for journeys on motorways and major roads. Three radar sensors with a range of up to 150 metres permanently scan the carriageway in the direction of travel. When you approach a vehicle in front, the engine management and brakes adjust your speed so that the distance is automatically kept constant – and if necessary, the vehicle comes to a standstill.

When the lane ahead becomes clear or the vehicle in front speeds up, Active Cruise Control accelerates again until you reach your desired speed. To move off again after the vehicle has stopped, the driver has to give the command to accelerate manually, either by briefly pressing the accelerator or pressing a button. If the stop lasts from 1 to 3 seconds, the vehicle moves off automatically. Up to four cruising speeds can be pre-programmed and called up at the push of a button.

Active Cruise Control keeps your preferred speed constant within a range of 30 to 210 km/h and automatically adapts the following distance to the vehicle in front of you. The Stop & Go function even controls the speed when the car slows down to a standstill and restarts the engine automatically after a short interval, e.g. in a traffic jam.

On multilane carriageways, the system detects whether another vehicle is only driving in the adjacent lane. Furthermore, if you wish to resume full control of the vehicle at any time, all you have to do is briefly press the accelerator or brake in order to deactivate the system.

Active Cruise Control with Stop & Go function is not an autopilot. Consequently, if the vehicle ahead brakes harder than expected or if the system detects a critical situation, the driver receives acoustic and optical prompts to take action. Driving in heavy traffic thus becomes noticeably easier and tiring situations such as traffic jams become easier to master with greater concentration.

Now I’ve got a few miles, the ACC is really good. Coming out of London on the elevated section of M4 which has a 40mph limit, with Driving Assistant Plus - the car drives itself. Even in this very stop/start traffic. At higher speeds there’s just the minor inconvenience of steering accurately, but the decision making and execution is just right.
The only time the system gets caught out is when I get cut up - sudden lane changes by a vehicle in front are caught but late and dramatically. I have gotten used to intervening when this happens, nowadays.
