Maximum Gas Mileage

[Travis Wills]

I fully understand that most people couldn’t care less about mpg with the Stinger. However, I really like the fact that the Stinger has all of the power I want but only when I want it.

I can simply flip a switch into ECO mode and I can get what is actually rather impressive gas mileage if I am just relaxing down the highway on a Sunday drive.

I was able to achieve 31.4 MPG in my 2019 RWD GT2 over 128.5 miles this weekend. This was cruising down the highway but I am not sure what my average speed was because I can’t locate that statistic in the car. Does the Stinger record average speed? I know my son’s Kia Rio has it.

I got 31.3 mpg going down to Charlotte on the way out. However, I stuck to the smaller highway there which has a 55 mph speed limit but it also has many stop lights. I had 32.5 MPG for most of that trip and then I hit the stop lights and stop signs and my mpg dropped to 31.3.

I have to acknowledge that I achieved 31.4 mpg by hypermiling. I was using the nifty “coasting” feature the car has in all situations that I could. I also was able to draft off of some trucks which honestly makes the biggest difference of all.

I did 322.3 miles on a single tank of gas and I had 65 miles left in the tank according to the car display. That would have been 387.3 miles on a tank. Has anyone been able to achieve 400 miles on a single tank of fuel?

My total gas mileage for the whole trip was 29.1 mpg. That isn’t bad considering I put it in Sport mode for about 50 miles while I drove up to the go-cart track from south East Charlotte. I did several full throttle pulls on the way up there and that affected my overall mileage greatly.

I really am impressed with the car’s ability to be an absolute beast in sport mode but very comfortable and fuel efficient in ECO mode. I couldn’t imagine driving around in Sport mode all day. It is great for acceleration but it offers a very binary experience. The throttle is just too twitchy for my tastes when driving around town in sport mode.

I don’t think the Stinger gets enough credit for how versatile the car really is. It goes fast when you want it and doesn’t when you don’t.

I also take some rather long drives and have seen over 30mpg for 100+ miles even cruising at 75+ mph. The mileage is pretty good as long as you leave it in Eco and turn on the cruise control. If I leave it in other modes and take full control I tend to average mid 20s.

Thankfully the vast majority of my mileage is highway, because the car is not very efficient in the city lol.

I happened to pull off 29.9 MPG on a trip to Spokane, all highway, on winter gas with winter tires and AWD, which usually nets the worst fuel economy.


*Thought divergence*
My thoughts on fuel economy though, the idea that modern engines perform "a lot" better than older engines is somewhat false in my opinion.

My old Grand Prix GTP (3.8L Supercharged pushrod 2V engine) was able to get this same fuel economy on the same fuel on the highway. The advantages on the Grand Prix were less weight (~3600 or so LBS) and only driving 2 wheels. Both cars had a similar physical footprint though. The Grand Prix also had a 4 speed transmission, not 8, therefore gearing was likely not optimal; also, 0.5L more displacement.

Considering the Stinger carries an extra 500 or so LBS, has AWD, sure the fuel economy isn't terrible, but modern engines aren't that far advanced regarding fuel economy in my opinion. I'll always defer to the fact that cars like a certain stoichiometric fuel mixture required, and require a certain amount of torque to maintain momentum, therefore until friction (on numerous parts) is reduced, or we are able to get away with leaner mixtures (like the old lean burn Honda's), I just don't think fuel economy will ever be that incredible, just simple physics.

Cruising at 70 on the highway I can pull off at least 33 if I’m not heading to the mountains. I leave it in comfort mode. Never noticed a difference in ECO mode. I think Eco mode is good for around town.

You can get it to say 33 mpg or you can average 33+ mpg over a long distance? Those are two drastically different things. I would find it hard to believe that you average over 33 mpg at 70+ miles an hour in a V6 Stinger.

30+ mpg would be a dream come true for me.
I haverage 19-24 mpg

I drive 42 miles one way to work and on a good day with little traffic I can get 33mpg on my drive info as I pull into the parking lot at work

Everyone is different.. I just ordered the pedal commander to get even faster-than-sport response and hopefully a bit more linear, not "push 75% to get 50% throttle". If I had to live with ECO mode pedal response, I think I'd get a Charger SRT or something.. I've been in ECO a total of maybe 5 minutes of 4500 miles

To get that gas mileage I think you have to be going the speed limit of 55, no faster.

I've said it already a couple times. 70mph

i only get around 16 MPG? i had it in eho mode for about 15 miles on my way to work and was getting 26MPG

What about heading in the other direction? Any elevation change between home and work?

With summer blend fuel I routinely see 31-33 mpg on the interstate at 65-70mph. However, you have to be very light on the accelerator. Even then, when your Stinger 3.3L suggests you are getting 30+ mpg and you do the actual math when filling up, it is almost a certainty that the actual fuel economy is 1-2 mpg lower than the trip computer is displaying. So yes, 30 mpg is still possible in some highway driving scenarios.

Maximum fuel economy for a Stinger is going to take place at a speed where the transmission has shifted into the 8th gear, and where it does not have to shift to a lower gear frequently.... i.e., level surface at maybe 50-55mph. I don't drive any nearly flat, level roads without traffic signals where 50-55 mph would be feasible, but such a driving condition would likely yield an actual 35+ mpg.

How many smile per gallon do you get. I am happy even just one per gallon

 

[CKeeler]

On the way home I drive harder and cruise at either 75 or 80 and I still get around 27. I’ve got a heavy foot on the way home most of the time.

What is your average speed though. If it is 55 mph then that sounds possible. If it is 70+ mph and not downhill then that doesn’t sound possible.

 

[CKeeler]

6 miles to the freeway all downhill. 32 miles freeway cruising at 70mph elevation changes up and down. 2 miles flat road from the freeway to work.

If you ever get the chance can you take a picture of the trip computer at the end of that drive? I would like to see what the average speed turns out to be. You can reset the trip computer once you are heading down the road. No need to add in the gas mileage for backing out of a driveway or stoping at traffic lights. We already know that will produce bad mileage.

I am just curious to see how you are achieving that kind of mileage at those speeds. Are you drafting behind trucks?

Standard GT doesn’t give me the average speed. No drafting. All I get is distance, avg mpg, and time

I've done two 400 mile tanks, in July and August of last year. The car probably had another 50 miles left before it stranded me too, since I only ended up putting back in 14.1 gallons on a 405 mile trip. AFAIK, my Fuelly means that I would have the first place trophy for V6 Stinger MPG, if that was a thing, and I still put my foot to the floor a few times a week. The trick is that I only have one stop light on my commute, and my average MPH is like 50 between work and my house. The city mileage really kills your average, but thankfully I have no City.

Here's my Fuelly for 24k miles in my Stinger: Stinger V6 (90% Highway) (Kia Stinger) | Fuelly

You can sort by miles in the log book section below.

As a note though, the trip computer exaggerates by about 10%. My average on a tank of commute is 27 MPG, but the trip computer always reads about 30. My best tank, 29.7 MPG, read 33 on the computer.

One of my best tanks was a drive from my house to SLC and back, 278 miles, 29.62 MPG, measured at the pump. 72 MPH cruise, probably averaging 60 over the whole trip (Base GT does not show average speed) The computer read 33 MPG, and 10% over seems about right from my measuring. (I've tracked every single fuel up for the last 24,000 miles). It's possible to hit 32-33 real MPG (measured at the pump), but would need to be high elevation and completely flat. This particular drive starts at 5100 ft, goes up to 8000, and back down to 4100, then reverse for the return trip.

Contributing factors:
No Traffic - Easy enough
Medium-high cruise speed - Again, pretty common plus for MPG. Would be more efficient if I had been cruising at 65.
High Altitude - Less drag. Yes, less air also = less power, but it's a net positive in favor of mileage
Lower trim GT - lightest version of the GT
RWD - Less drivetrain loss, lighter car
