All for 1 mile per gallon, that is why I purchased a leftover 2015.
If you assume 12k miles per year, 19 vs 18 mpg, and 1.80 for gas over 5 years the start stop system would save you $315.50 or so. I couldn't find a 2016 starter, but a 2015 costs $91. Two hours of labor and you'd break even. That means that if the starter lasts past the warranty you're saving money.

Obviously these are just general wags at numbers, and a heavy duty starter is going to cost more, but in the long run it is likely to save you money, especially if you get the maxcare service contract.

Is the second battery AGM, and where is it located? And now two batteries to replace every 4-5 years!

Yes, the 130A auxiliary is an AGM. I'm not sure of its location though.

Got to try out the ESS when I drove a 16 today. It wasn't as bad as I thought it would be but I'll still be punching the button to turn it off.

Re: 2016 Owners...how's the stop and start working?

Personally, if they're going to really move toward fuel savings, I wish they would incorporate plug-in hybrid technology that could allow the Jeep to make those short trips around town completely on battery power. Even if the battery range were only around 15-20 miles before it needed to kick in the gas engine, that would allow a lot of driving each week on battery power.

In my case, I live less than 5 miles from work. I could make my entire round trip commute and still stop off for groceries on the way home without touching the gas engine. Since I have a garage, plugging in overnight would be no problem for me.

I dunno about this one. Between the electric motors and batteries, that would add a fair bit of weight to an already heavy vehicle, not to mention having to find places to put those batteries. I, for one, wouldn't be too willing to lose any of the storage space I have. Once the engine has to kick in, it's going to be moving even more weight, dropping the mileage.

Re: 2016 Owners...how's the stop and start working?

I have a summit 6 on order. I was worried about having another battery and the extra weight it would bring, but I looked into this. The picture I saw of the second battery shows a battery that is not a standard automotive battery but a much smaller battery. I don't believe it will add much additional weight. At least nowhere near as much as a large automotive battery would add.

Japanese owners of the Honda Civic have this very thing in the exact same form factor as the Hybrid version we have in the US. In fact, you can get a kit to run fully electric and there's even the same spot available for the second battery. You won't go very far compared to a full electric, but you'll probably knock of 30 miles of gas use each day.

As far as I can tell, the new system adds a second starter and battery. They could sub out the starter for an electric motor and use the second battery for motive power.

We're talking about a 4500lb+ vehicle here. Plus, I wasn't calling for Tesla levels of mileage, either. 20 miles or so before switching to gas power would make a huge difference in most people's daily driving and require a minimal percentage increase in weight. The average commute is around 10 miles each way. If they could eek 20 miles out of these vehicles on electric power before switching to gas, that would allow people to drive to work and back home almost entirely without using gas.

The reason they don't do this is American based manufacturers have an allergy to plug in electrics except in tiny little vehicles that were never gas hogs to begin with.

Until the government switches the rules from average fuel economy to minimum fuel economy based on class, we won't ever get the kind of efficiency we should be getting out of vehicles of this type. It's the 24MPG or less class we need to improve, not the little tuna cans.

Don't forget the highly variable cost of electricity (over the life of the vehicle) and it's attendant generation impacts.

Likely far less than the equivalent costs and impacts of gas usage. That includes even the worst generation technologies, which are still far less polluting per vehicle than running a gas motor due to economies of scale.

I believe that various forms of hybrid are planned for the next gen platform and on other FCA vehicles...I recall reading that somewhere.
