Horrific Gas Mileage Hemi eTorque

[737flyer]

Bought my 19' Ram Rebel with eTorque Hemi on 9/28/18. I had numerous longer trips to take and mileage has built up fast.

Just getting ready to pass over 3,000 miles thanks to a trip from Orlando FL to Central KY and back again.

My issue: horrific gas mileage! I simply can't figure it out. My drive was 1600 miles roundtrip, not towing, with just myself and baggage in the truck.

My fuel mileage (all highway, with cruise control engaged at speed limit) on the way up = 15.0 mpg hwy, my mileage driving back tonight is 14.8 mpg. While the sticker rates the truck at 17 city/22 highway, I never expect to achieve those numbers. But 15 city/ 19 hwy is what I got on my 2011 Hemi. I at least expected that.

This is my 4th Ram, and I know something must be wrong. I'm not dragging a brake as I check brake temps, and they were cool to the touch.

MDS almost never activates and the truck downshifts on even the slightest uphill grade. At 70 mph and 1850 RPM (.392 gears), there's ample torque to never require a downshift on moderate Florida hwy grades.

I'm fearful that the eTorque motor is causing a high amount of drag during hwy driving conditions. I guess it's back to the dealer with my fingers crossed.

Break in mileage? Perhaps get a bed cover? You don’t have a signature with your truck but is it a loaded crew cab with more weight? But my main observation is there is no way the rated MPG was for 3.92 gears. That is an option and I would expect it to significantly affect highway mileage. Maybe not and would be interesting to see what others are getting with that rear.

I agree this seems low. The Etorque Hemi models are getting nearly 2 mpg better mileage over the non ET Hemi, based on Fuelly numbers. The technology adds weight, so when doing long highway trips, there may be a drop over a similarity equipped non ET. The technology shines brightest in city driving.

Let us know what the dealer finds. Also, consider signing up with Fuelly to track mileage and add to the body of knowledge about the new technology.

 

[Jus Cruisin]

Hand calculated? That is low compared to what I was getting running to Michigan and back.

Fill out your signature so we know what you have.

The MPG was my the sole reason to stay with the 3.21. The window sticker isn't changed with optional gearing, which is very misleading. What gearing did your 4th gen have?

 

[Mducred]

I passed 1k miles today on my 19 Rebel and I have been averaging 17.3 mpg so far. This both city and highway as its my daily driver.

 

[Han Ridge]

I have a 3.92 differential with no etorque. On the MPG gauge I get approximately 22 highway and 16 city on 87 octane. When I fill-up and use a calculator I’m averaging 17.5 In Charleston SC which is in the low (flat) country. Towing a 5200 lbs Travel Trailer I get 9.5 mpg. I can get 21 in the city by feathering the accelerator and paying close attention to braking but its not very practical or fun.

This is 60% stop and go driving but I've got a lead foot

 

[Biga]

I am averaging 17.6 with my Etorque 3.21 gears 4x4. Almost all stop and go driving to work and it will hover around 17 mpg. I got 21 mpg on a trip to Chicago last week mostly all highway.

Very interested in what your dealer has to say. My eTorque is getting slightly better than what yours is, but not nearly what I expected. I have about 1500 miles on mine now and I will say the city mileage is slightly improving. Part of the issue is that start stop so far has only been active during my morning commute. In the afternoon, it is still to hot here in Texas for the climate control to get things cool enough to allow it to kick in.

I use Fuelly to track my mileage but have not seen a way to choose eTorque as an engine option so my results are part of the "Regular" Hemi numbers.

Folks with Rebels should not expect to get quite as good as non-rebels. Similarly ORG should not expect quite as good as non ORG. 2 main reasons

Rebel and ORG are raised higher in the front, and will have more wind drag as a result. This will impact MPG negatively, especially above 55. (air suspension will help counter this)

Rebel and ORG stock tires have higher roiling resistance.

Rebel does not have the lower air dam that drops at speed either.

The sticker EPA ratings is not specific to the Rebel model or ORG trucks, but is the standard 1500.

There is no reason to expect lifetime average MPG of mixed driving for non-etorque trucks much above 15-16 MPG.

There is no reason to expect lifetime average MPG of mixed driving for etorque trucks much above 16-17 MPG

If you have 2wd, you can add 1 or 2 MPG to that.

If you have a Rebel you should subtract 1 or 2 from that.

3.21 should be slightly better for hwy commutes than 3.92

Your mileage will vary depending on fuel, wind that day, elevation, speed, driving habits, etc.

As always, your mileage will vary. It seems the 2019s posting on fuely are a little worse than 4th gens. I've been tracking fuelly for a while...2018s have ticked up from upper 14 avg to now lower 15 avg. I expect the same for 2019s. As the computer leans to be more efficient, your MPG will improve slightly.

I'm averaging 14.2 hand calculated for my truck. EVIC lie-o-meter is currently saying 17.0

 

[Bwarren2]

I have 200 miles on my Rebel, so the engine isn't broken in. In past trucks, Its taken to get well over 1K miles to see MPG improve. ON the HWY this AM I was at 19MPG, in the city i'm at 14.5 ish.

 

[uTurn]

I've ~1,800 miles on my Limited, averaging ~15 MPG w/3.92 gearing. I set the truck at Aero mode with my daily driving being mostly city. The short highway trips I've taken have returned ~19 MPG. Love this truck!

 

[drsubie]

I have ~1100 miles on my '19 Limited 4x4 w/ 3.92, no bed cover, 5.7L non-e-torque. I drive pretty conservatively, mostly CITY miles, and fill w/ 91 oct. OEM 22" rims w/ OEM all season tires (not off road). Car computer says ~12.2 to 12.4 avg MPG. Yikes!

You bring up great point. What gas are people putting in. I am assuming it is apples to apples with mid grade cause that is what the manual says to do. But I know a lot of people don’t b liege that for normal flat highway driving. That can definitely make a 1 or 2 mpg difference.

 

[Flot]

I have essentially the same truck - hemi non-etorque 3.92, 4x4. I can'

Yeah, this is much closer to my mileage. I'm primarily city but I think my 3000 mile counter is showing mid-low 13s for combined mpg.

I do use the remote start a fair bit, I assume that is negatively impacting the result.

 

[drsubie]

I meant to say "city" driving LOL... in any case, the MPG and power is less than my '13 F150 V6 Ecoboost (that had a tune and upgrades), but my truck isn't broken in yet. While a smidge disappointed in outright power and MPG, the luxury amenities (and safety features) and smooth power delivery more than makes up for it...

Not sure eTorque would cause drag any more than an alternator would.

I am averaging 17.8 over 7500 miles. Just got back from a trip to NC and did 22.1 on highway with 87 grade. Non Etorque Hemi 3.21 gears.

 

[VaderRebel]

My foot hits the gas pedal like Thor's hammer. Avg is 14.5, about 2000 miles on non eTorque Rebel. If I drive like I'm driving Miss Daisy on the hwy I can get 17mpg.
