Re: Real World MPG

I'm getting around 11 to 12 mpg with spirited driving with stop lights about 1/8 to 1/4 mile apart. Haven't been in stop and go yet so can't comment but on the freeway in auto mode it looks like about 16.5-17.5 cruising at 70 mph and I did try Eco for a few miles and it quickly jumped to over 19. Cruising on the freeway in sport is what I like and with a blast to 80 here and there I'm at 15-16 . That's my experience so far with 800 miles on her. I'm thinking once the motor has a few more miles it will be get a bit better on gas mileage.

Re: Real World MPG

I used to have a 2011 5.7 Overland, just traded it in on a 2015 SRT, and had concerns that my mpg was going punish me. The 2011 was averaging 15.7 mpg for me and the 2015 SRT has been consistently at 16.4. I did have a bit larger tire on the 2011, but I do the same driving that is a blend of 80% highway / 20% city and 90 miles a day during the week.

I will say that when I start getting the itch, it doesn't take much pull that average down quickly.

I was pleasantly surprised to notice on a recent interstates trip that cruising (not cruise control, but at steady speed) between 50 and 60 mph (don't remember exact mph), the instant mpg was showing 25 to 35 mph on flat ground.

But at usual keeping-up-with-the-traffic interstate speeds in the 70's, also on flat ground, usually it shows instant mpg of mid-teens to very low 20's on flat ground.

Passing or climbing on interstate knocks instant mpg down to high single digits or barely above 10 mpg.

This is with 10% ethanol fuel, Eco always on, 4x4 in auto. V6 3.6 liter gas Pentastar, 8 speed automatic, '15 Overland, 20" wheels with OEM Forteras at about 40 psi cold (dealer psi recommendation for the winter).

So far, with less than 2,000 miles, I'm averaging 17.9 mpg (my calculations), 17.5 mpg (the Jeep's displayed average in DID/EVIC).

Best average was 22.7 mpg on an all interstate tankful.

Worst average was 14.4 mpg local driving, often in heavy snow conditions with lots of idling and 4x4 in snow mode.

I should add that I really like the way Jeep implemented the DID/EVIC fuel economy gauge view.

Re: Real World MPG

What rises consumption in winter is mainly the cold engine. Let´s say if you drive everyday 2-3km city the engine will hardly get out of its cold start cycle so over 30l/100km is not uncommon. Anyway my wife drives our H2 every morning around 5km and the consumption is around 25-27l/100km. I am curious how high our gas mileage will be when we finally get the car.

In the winter most people have their heater or defoggers on. Defoggjng or just having the heat on activates the air conditioning compressor which puts a extra load on the on the engine. Even the rear electric defogger you will notice the engine rpm go down because of the extra load on the alternator, which is a extra load on the engine. Turn those off when you can and you should see a slight improvement.

Re: Real World MPG

Auto start will significantly lower your MPG's also.
