Auto Start Stop and Auto Hold

[Edmguy]

It "feels" a little weird that the 3.3T "lacks" a feature the 2.0T has; plus there may be drivers who want the added benefit of saving a little fuel. However, as far as I know, no cars with auto start-stop gives the driver the option to "permanently" disable the feature; I wouldn't want my car to have this because it on by default every time I start the car.

One of big reasons for me choosing the G70 over the Stinger was that the G70 didn't have the auto start/stop. It wasn't smooth at all in the Stinger and I hated it. Driving the 2.0T Elite as a loaner, I really disliked it in there as well. If you didn't feel the engine starting or stopping, it wouldn't bother me, but you can really feel and hear it so it is irritating.

The car that I traded in for my G70 was a 2015 BMW X1 with the 4 cylinder turbo 2.0 litre engine. This car had a disable switch on the console for auto start/stop which most cars have but auto start/stop would definitely remain disabled after the car was restarted so you could permanently switch it off if you wanted.

This is rare, the reason being that for any fuel economy-altering feature that can be permanently disabled or set as default, the consumption ratings must take into account the feature on and off. This applies as much to ISG as it does to Sport mode. So in the case of BMW, they opted to take the fuel consumption rating hit. Most companies do not.

Well...it looks like the Sport DOES get the “auto engine shut off at stop”.

But only in the 2.0T (RWD and AWD). 3.3T does not.

Proof...look at this 2.0T Sport...find the shifter photo near the end...

Then we can say that all 2.0T but the MT have the Auto engine shut off and the 3.3T doesn't.

Correct. This isn't new info - it's always been planned for the 2.0T A/T models to have ISG, while the 2.0T M/T and 3.3T models do not.

Doesn’t work like that, car has to be at a full stop, foot fully on brake, rpms lower then XXX for more than XXX seconds.

I’ve driven 2 cars with it and can’t ever recall idle stop turning off the car in stop and go traffic, or even at a stop sign, only at a red light pretty sure the timeout was 10-15 seconds or some such, which is a long time in stop and go traffic sounless traffic is dead stopped it won’t engage the idle stop, If you are creeping along then it won’t turn off the car, even the SCC start/stop rarely disengages on me in L.A. stop and go traffic and it’s timeout is 3 seconds.

We didn't care for the stop feature. We had it on our GLA45 AMG. It's added wear and tear on the starter and didn't make any appreciable difference in fuel economy. The only saving grace was, you could turn it off manually. The Auto hold feature is always a plus.

As in the GLA45 AMG, it was only active in eco mode. I don't know if it will be the same for the G70.

Auto Start/Stop vehicles have a seperate starter. No wear and tear on the regular starter. It's a well tested technology!

Can someone clarify, is it just the 3.3t Sport that doesn’t have ISG, or do ALL 3.3t G70s exclude the tech?

 

[Beefer]

^ only 2.0T AT have it. Thank goodness

I kinda wish the 3.3T did have it - IF it was reasonably smooth and reasonably intelligent. My experience with auto stop start (nice acronym btw...hmmmn) on Acura, Porsche, Audi and MB is good. On BMWs, not so much, unless they have improved it over the last few years.

I had a loaner G70 2.0 (elite package) for 5-6 days and the I hated the auto start/stop. I looked around in the settings to see if there was a way to not have it set by default but I couldn't find it. I guess you have to just train yourself to push the button OFF every time you start? It's a nice to have feature but having it by default really pissed me off..

I can only speak to the 3.3 Sport and I can say with certainty that it doesn't have this feature.

Glad they didn't put it in the sport versions. So glad.

Count me too.

Guarantee the reason it isn't included in the 3.3TT cars is because they couldn't get the NVH to acceptable levels since V6s are so inherently unbalanced. As far as I know right now the only V-configuration engines that have it are the Ford 2.7L Ecoboost (which I drove and liked it in an F-150.) I don't know how they were able to figure it out, but Ford is actually quite good these days with solving NVH issues. (Drive a Fusion Hybrid and tell me it isn't far more refined feeling than Toyota's whatever-the-hell generation Hybrid Synergy Drive.)

All that being said, I have a '15 Genesis Sedan with a buttery V8, and the base model (ugh, first world problems) G70 loaner that I'm driving right now usually gets the ISG system left active (becuase I want to like it) and every time it restarts while I'm still stitting still in traffic, my first reaction is to look in my rearview to see who just rear-ended me. It feels really really awful and I'm not sure how Hyundai (not even Genesis, Hyundai's of late have pretty great NVH isolation) let this implementation go to production... Everything else is so well engineered and then a few things just fall flat. (Don't even get me started on how the rain-sensing wipers don't automatically turn on the headlights...) Now, if I was buying a G70, I'd have the 3.3TT, so this wouldn't be an issue for me anyway, but put me in the peasanty-est Genesis you have on the lot when I dropped off my fully decked "G80" and see if I don't bitch.

Doesn't the Stinger have it?

Standard on my Jag F Pace 35t, with supercharged 3 liter V6.
