My daily commute is 80-85 mph (or you get run over) and I average 25 mpg. Weekend driving in town I get around 23 mpg. I've only taken it on one towing / fishing trip and am following the 50 mph during the first 500 miles of towing and mpg was bouncing between 28-32 mpg with the boat attached, lots of winding roads.

My previous vehicle was a 14' Cherokee v6 Pentastar 4x4 Trailhawk and towing was 15-17 mpg.
I also towed with my 12' Charger that had a v6 ( yes you read that right, I threw a hitch on a 2012 Charger the boat is only 1700 lbs, under the 2k limit) and it averaged 17-19 towing.

Most large cars are more than capable of towing the same weight as their SUV siblings based on the same platform. This is because most crossovers / SUVs are also unibody construction as their sedans / wagons. The BodyOnFrame car is extinct (crown vic was last of them) and the BOF SUV is almost there as well.

45 MPG at a steady-state 55 MPH

These MPG values were as shown on the EVIC's instantaneous MPG values when driving for a few miles. Elevation was near sea level, between 200 and 600 feet.
I duplicated my 45 MPG value the other day, on Friday 13 March, from Mountain View, CA to Hollister Hills SVRA and back. This was on highways CA-85 and US-101 at near sea level (elevations 100' - 300'), gently rolling hills, no appreciable wind (trees, leaves and grasses not visibly blowing), and with the A/C on.

On the freeways at a cruise-controlled 55 MPH for the 98 miles there and back I got 45.3 MPG. That's basically 45 MPG for 100 miles!

I did this by:
(1) getting up to cruising speed on the freeway;
(2) then, setting the cruise control to 55 MPH;
(3) then, resetting my EVIC trip odometer.

I read the EVIC's reported trip MPG before I slowed down to exit the freeway. My JGC is stock, no roof rack (yet), with Goodyear Forteras inflated to 38 psi.

At 55 MPH everyone is passing me. Big rigs driving near their legal speed (55 MPH) were also passing me. Of course I stayed in the far right lane except a few times when traffic was merging at an on ramp, and only if the left lane was clear I merged over for a few seconds and then merged back. Most of the time, though, traffic to my left lanes were going 10-20 MPH faster than me, and I just stayed right.

45.3 MPG!!! Amazing.

In 3 weeks I drive to LA, then Phoenix, then Las Vegas by way of the Grand Canyon's South and North Rims (hopefully the North Rim isn't snowed in). On that road trip I plan to make more measurements and report. But, I don't like driving slowly!

Here's my planned 2,200-mile route: https://goo.gl/maps/o3Cle.

ROAD TRIP!

Re: Eco Diesel Mileage

I've successfully calculated the worst mpg;

17.5 mpg over a 100+ miles trip

Conditions :

85mph with a bass boat in tow in 45 degree temps

Set the cruise 10 over the speed limit of 75 and flew home.

Re: Eco Diesel Mileage

25.1mpg over the 1700 miles we've owned it. 80% city driving and it's been quite cold down here.
I do run a splash of fuel additive and keep tire air pressure high at 46psi. Both seem to help.

Re: Eco Diesel Mileage

I have 29,000 miles on my 2014. I have been tracking my mileage and keeping it on fuelly (JGCecodiesel) pretty regularly. I am averaging 24.5 mpg. My best tank was 33.8 mpg! I drive more highway than city but am in the mountains every weekend.

I'm pretty happy with my mileage so far. I have about 5000 miles on it and towed for the first time with it this weekend. I took the snowmobiles up to my parent's cabin for storage and got just under 19 mpg on the way there towing the trailer and just under 27 mpg coming back empty. The trip was about 500 miles round trip.

Re: Eco Diesel Mileage

Reset the evic before the first road trip and managed these numbers. 30+ mpg mostly interstate highway driving with some secondary and a bit of town mixed in. Really impressed and with 1/4 left in the tank! Did even better on way there but cooled down several degrees on way back.

Re: Eco Diesel Mileage

I just logged 30 MPG crossing from Redding to Arcata, CA on US 299; 140 miles and 4 passes @ ~3000 feet.

Had the ACC set at 4MPH over the PSL for a lot of the way (I'm really liking the ACC on mountain roads...).

Going the other direction from Hydesville to Red Bluff, CA on CA 36 [134 miles and 6 passes - 3 over 4000 feet] I got about 27.5 MPG. ACC is pretty much impossible to use on most of this road.

In the past, I've only gotten 30 MPG or more on long stretches of Interstate cruising at about 69 - 72 MPH.
