New 2016 Efficiencies?

From what I have gathered the 2016 JGC Ecodiesel gained electric power steering and some lighter weight suspension parts. Combined, you would expect some increase in fuel economy from these updates. However the EPA shows no change in fuel economy when comparing the 2016 versus the '14 and '15. One thought I have is the EPA MPG figures are whole numbers, not showing decimal point accuracy. It is too soon to get anecdotal info from Fuelly users who post their data. I would love to know if the updates to the 2016 Ecodiesel had any impact on fuel consumption. Anybody have any info?

"EcoDiesel has the same fuel economy ratings as the 2015 models, but the 2016 models have received some changes that you cannot see – but you should be able to feel. The engineers have adjusted the fuel delivery system for improved combustion (although they don’t clarify whether or not that improves tailpipe emissions, since it doesn’t improve MPGs) and more importantly, they have adjusted the throttle controls for an improved driving experience."

The curb weight is exactly the same on the 14 to 16 models, so you should not expect any mileage change. The earlier models with diesel have electric steering too, for 16 they are hyping that they improved the software for it.

Somewhat incorrect. All engine choices for 2016 received an all new electric power steering system.

There's a rumor that the 2017 EcoDiesel will have actual changes/improvements.

Re: New 2016 Efficiencies?

I shopped 2015 GC diesels extensively before deciding to order a 2016. Both the 2015 and 2016 diesels have electric power steering. FCA may have changed the electric ps in the 2016, but I can't tell any difference. A comparison of part numbers might verify that there is a difference.

I have just over 1200 miles on my 2016 Overland. I have the Advanced Technology and Off-Road Adventure II Groups on it, so it may be a little heavier due to the skid plates/tow hooks/etc. and has the 18" wheels with Wrangler ATs. I am getting 26.2 mpg (manually calculated) doing primarily city driving.

Re: New 2016 Efficiencies?

EPA is a testing procedure applied by OEMs through either getting the vehicle tested on a Dynometer in a laboratory under set conditions or do tests at their own laboratory, or even none of this and instead applying an algorithm to a new vehicle that uses the same engine that was previously tested. For instance, let's say Jeep had the WK2 tested with the Pentastar and then made the Durango with the same engine - they likely didn't retest the Durango but determined what it's expected mpg based on the weight, drivetrain, and drag to name a few elements.

The EPA test loop is misleading as most people with gas engines don't get EPA except in the best cases whereas us diesel owners get EPA more often under average driving. They need to change EPA to give best and worse case findings (get ride of city / mix / hwy ratings). They also need to change the test to more accurately show how people normally drive.
