With the upcoming 2018 JL Wrangler, Jeep is coming up against stricter fuel economy standards and consumer pressures to make the Wrangler more fuel efficient. Aside from a rumored exterior redesign, the current 3.6L V-6 engine might also get a technical tweak that could help MPGs, something our friends over at JLWranglerForums picked up on.
Jeep is rumored to be incorporating its ESS technology (Engine Start-Stop) with the Pentastar engine in the new JL Wrangler. ESS technology isn’t new to the automotive industry, FCA actually started using the function on the 2013 Dodge Ram 1500. The technology will monitor the Jeep and actually pause the delivery of fuel during prolonged stops, causing the engine to shut off.
When the accelerator is pressed fuel delivery starts again and the engine starts. This cycling of on/off engine fuel management has reported up 1 mpg gain in fuel economy. With a vehicle that is already on the low end of fuel economy, every MPG helps.
Recently, ESS was introduced in the 2016 Cherokee and has rendered up to a 3% increase in fuel economy, for the same Pentastar engine in current models and the upcoming 2018 JL Wrangler. It’s important to note that rumors also indicate the ESS function will be an “auto on” feature, meaning that although the function can be manually turned off, it will restart the next time the Jeep ignition is turned on.
Let us know what you think of the feature. Do you think the benefits outweigh the inconvenience? Also, do you think drivers should have the ability to permanently disable the function if they choose to?
After years of pleading by Jeep owners and rumors from Chrysler executives, it seems that the highly anticipated 2019 JT Wrangler Pickup might be one step closer towards the confirmation of a production date.
Recent reports point to manufacturing re-tooling in late March 2018, followed by full ramp production of the JT Pickup in October of 2018. This time table remains within the standard retooling scheduling as with past generations in the Toledo plant and set the JT Pickup as a 2019 model release.
