2018 Jeep Wrangler - incremental FE improvements
 

This is for the 3.6l Pentastar V6, which will probably form the bulk of the Wrangers sold, paired with either the 6-speed manual or the new-for-2018 8-speed auto. A 2.0T I-4 and a diesel are expected to be released later.

They sold the old wrangler here in small number, had a huge 2.8 diesel but was slow and underpowered, it took a leisurely 13.5 seconds to hit 60 and fuel economy wasn't great either.

I'm sure the new engines are a lot better, although reading that, a few options only see a 1 MPG improvement combined, doesn't seem like huge progress to me.

The numbers are small but it's a solid 10% increase. It's like when I got my truck (16T) and modified it to go from 8mpg to 8.5mpg. People would laugh and say so what and I'd say do the math on 90k miles a year. Then not so small a deal. Not that these Jeeps are like that but still a solid 10% increase is better than a poke in the nose.

Cost is one thing, most people won't notice a 10% difference per year on fuel so cheap anyway, but as far as C02 targets go, we are all (apart from the US) required to slash them significantly, I just don't think 1 MPG will make a big difference.

I hate diesel-gate for giving diesels a bad name, recently some car reviewers tested a new Mercedes-Benz wagon and got almost 80 MPG without trying (76.3 to be exact) an older one would have struggled to hit 40 MPG.

A 10% increase in something like the Jeep will reduce the amount fuel burned than a 10% increase in something more efficient.

10% is also the amount of increase the Prius had between generations.

Once fixed a roll over Jeep, $1500 in damage and killed 3 people. Never had any interest in one unless it was a WW2 made model, then it would need a roll cage and all occupants in a 4 point harness.
