US MPG - Real World Numbers

[westcoastGT]

That's odd. I just read through a thread where people's hair's on fire because their car can't do over 140...

The fire department was chasing me down the I5 !!!

 

[westcoastGT]

Actually just got back from a round trip to Seattle today and improved my mileage because I used the smart cruise there and back !!
thats a very cool feature ..................( also only 1 person and no luggage )

 

[moinmoin]

smart cruise

I am going to keep that in mind....thanks for the pointer.

26.68 Imperial Miles Per Gallon this trip

 

[Vaoh]

I got my base model GT RWD doing roughly 30 MPG highway and around 24-25 city, all driving in Eco mode. Manual calculations have my economy at 27 MPG average which seems about right with what the onboard computer is telling me.

20 to 21 ish trying not do burn out every single time I am at a red light XD

For people looking to trade up from an Optima, the info in this thread is eye-opening.

I drive smoothly and always uses cruise control, and 32-35 mpg on the highway is a cake walk in my 2.0T SX-L. And that's on Regular gas and at interstate speeds (75-80). I don't mean to sound like a miser, but to pay 50-60 cents more per gallon, and get 25% lower mileage from those gallons, is a real bummer.

I really thought the 8spd trans in the Stinger would mean there's a high 8th gear for lower-rpm highway running (and good mileage). Guess not.

(And please don't beat me up with the usual "This isn't intended to be a Prius" remarks. I know what it is, but when you get used to not throwing money at gas pumps, going backwards is something to think about.)

The GT engine has 2 cylinders, 1.3 liters and 1 turbo more than the Optima 2.0T, these are heavier and need to build more inertia to move, so at normal highway speeds, it is expected for the GT to have lower MPG. But.........when you want to use those extra 120 BHP, they are available at your foot. If you want similar mpg as the optima, then go for the 2.0T Stinger.

 

[Mach_Tuck]

I would agree that the 8sp SHOULD have better MPG at cruising speeds. It is what it is. IF you want the bigger engine, it wont come without a cost. If not, get the 2.0T.

For some options, the "pay to play" mantra really holds true

 

[mldavis2]

If you demand power, it costs fuel. If you're feeding 3.3L instead of 2.0L, it takes roughly 65% more fuel assuming the same engine load (which is not strictly true.) Add in wind resistance depending on your headwind and speed, and you pay more for higher highway speeds where wind resistance begins to make a difference around 45mph. Most cars are most efficient around 45-50mph, but that depends on final gear ratios as well. And on the Stinger, keeping it in lower gears decreases throttle response but saves fuel, so Sport mode is not your friend if you want mileage.

 

[JustThatPenguin]

I have a 16 corvette z06 so mpg is not something I worry about. I keep that on sport for that lovely purr. And I average around 8... Lol with the stinger I've always been keeping in sport so the rare moments where I have a slight clearing during my daily commute and I can floor it. I am averaging 15. So I am extremely happy. I actually did my morning commute today in comfort, driving like a grandma and I saw the meter hitting 30+ the whole time.

 

[mldavis2]

Yes, I would think even the 3.3L would be able to get close to 28-30 on the open road after break-in.

I have two big 6.0L GM engines in my cars, an LS2 in the GTO and an LS96 in the G8. The GTO is a manual 6-speed and gets around 24 overall on the highway at 70mph. The G8 has the 4-cyl. injector cut-out technology which will drop 4 injectors under very light loads - typically 60mph level ground - but at 70mph it's 8-cyl. all the way and with the 6-speed automatic in that one, it's good for about 25mpg @ 70mph. I know the load on the smaller 3.3L is a bit higher, but I would think it would be good for close to 30mpg eventually.

I know it's not apples to apples, but I had a string of Acura TL's and TLX's with a 3.5-liter V6, and I got some of the best mileage of any cars I've ever owned with them - 38-39 mpg on the highway at 75-80 mph. Weight about the same, and a slightly larger engine.

True, they weren't turbos, but a turbo should actually do well on gas mileage if you don't stick your foot in it too much and blow gas out the exhaust. After all, a turbo makes power without having to stomp it. In fact, I get the best acceleration out of my turbo Optima with only light pressure on the pedal.

The bottom line is that 25 mpg on the highway for a 3.3-liter V6 in 2018 ain't stellar mileage by any measure. It comes down to the 3.3-liter being around for awhile and not being known for good mileage. If scoot is all you care about, that's great. But Hyundai/Kia needs to do some engineering work to make that engine a little more efficient ... or come out with a better one.

I think you're right on track here. The Stinger GT isn't the most fuel efficient car. It may have to do with gearing because I'm pretty sure the engine itself is very well-designed...

 

[StungBlueGT2]

So for those who are already driving the car in the United States...what are you averaging so far on the 3.3 or 2.0 as they are "breaking in"?

3.3 RWD GT2 and I got 15.4 on my first tank and currently 16.7 on my second all with 90% city driving. But I'll admit that I can't help myself and will slightly punch the throttle from 2-4k often. Sport mode torque rush is so addicting!

 

[Berzerker]

So I'm almost 1750 miles in and my last 3 fillups have been hovering around the 320 mile range mark, which is about 20.1MPG average, which sounds about right since I do a bit more city than highway. I think this is where it'll sit and where I'll find myself.

I’m exactly getting the same as you with same situation. 1500 on odometer.

Here are my stats and a few others. It would be cool if more of us could track too!

A buddy of mine pointed out in my last post about mpg that the pic showed only a few miles tallied on the tripmeter when I snapped it. Today I decided to finish off the break-in miles with a road trip on I-5. 80 miles round trip, just me and a full tank. Here's my mileage from that trip. I own a 2.0 rwd, just to clarify:

Wow. You can’t fault that! Nice work.

Yep, definitely the four cylinder! LOL
