US MPG - Real World Numbers

[Merkur720]

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"?

Based only on the type of vehicle the Stinger is I would say it is below the government MPG figures. There is sure to be a lot of, "let's see what this baby can do" at least for a good while.

Highway w/cruise at 70-80mph: 25 MPG
Mixed (80% highway): 22MPG
Mixed (60% highway): 20MPG

Right on the dot with EPA's number. I drive mostly in comfort/eco. Hopefully these figures will improve as the car break in. Have about 600 miles on it now.

in mostly city driving and bumper to bumper traffic, in sport mode (and during the break in period), I am averaging 22MPG. Thats while always keeping my RPM above 2K and without the auto start/stop off.

That sounds pretty good!

I'm getting the same results as well.

Just wanted to give a quick update. Went on a road trip last week. Over a 100 miles stretch of highway, I was able to get 31MPG with eco mode and cruise control. Average at the end of the 350 mile trip was around 25MPG, with 250 miles on highway and 100 miles in city.

With 3.3 or 2.0 engine?

3.3. With 3 people in the car too.

 

[CO-bound]

I'm at the 750 mile mark (how, I don't know, since I haven't even left the city yet) and I'm averaging 22.8, on Chevron and Shell 93. I still haven't hit full throttle and only went over 4k rpm once or twice.

Anyone have any idea's on why I'm getting such low numbers? I've driven about 300 miles on mine now, almost exclusively in eco mode or comfort mode. I'm only getting around 18 mpg. I drive about 65% highway miles, 35% city. I've been very easy on the gas about 98% of the time in an effort to both break in the engine and to try and maximize my MPGs. I filled up last night for the first time (thus resetting the avg mpg) and was able to get around 21 MPG for the first 15 miles or so, but it has since inched its way back down to around 19.5 (and sinking).

It is VERY cold here (near 0 degrees, wind-chills below 0). Would that have an effect?

I've had my 3.3 awd for just over two weeks. No highway driving but light traffic given the holidays - I am getting a read out of 19.7 but a real calculation at the pump of 19 with just under 500 miles

Are people citing the mileage that the car is telling them, or are you determining the actual mpg when you fill up a tank? My Optima's readout can be as much as 2.5mpg off from reality since it's just an estimation. I'm hoping Kia got a little more accurate or these are calculated results from fill-up capacity.

Edit: Well clearly Mark right above me knows the deal but just checking on the other results if you guys could chime in.

Maybe, but only for a few minutes after you start it.
Catalytic converters only work when they are hot, in order to cut down on pollution cars run rich until the engine is warm so the cat heats up faster.

I wouldn’t drive in eco or comfort during break in. The manual says to keep RPMs between 2-4000. So I drove exclusively in sport mode which kept the RPMs where they needed to be. Even in sport I averaged 21-22. So not sure the issue

good point. I am going off the computer. My Optima real mpg was about 2-3 less than the computer. I’ll check real mpg next time I fill up

A normally aspirated vehicle will do better in cold weather because the air is denser but I doubt it would help as much with a turbo-charged engine. And I have no idea what effect such ridiculously cold temps would have. Stay warm.

Winter blend fuels are horrible as well.
Here is what the EPA has to say:

Cold weather and winter driving conditions can reduce your fuel economy significantly.

Fuel economy tests show that, in short-trip city driving, a conventional gasoline car's gas mileage is about 12% lower at 20°F than it would be at 77°F. It can drop as much as 22% for very short trips (3 to 4 miles).

The effect on hybrids is worse. Their fuel economy can drop about 31% to 34% under these conditions.

Why is winter fuel economy lower?
Cold weather affects your vehicle in more ways than you might expect:

• Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids.
• It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures.
• Heated seats, window defrosters, and heater fans use additional power.
• Warming up your vehicle before you start your trip lowers your fuel economy—idling gets 0 miles per gallon.
• Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds.
• Tire pressure decreases in colder temperatures, increasing rolling resistance.
• Winter grades of gasoline can have slightly less energy per gallon than summer blends.
• Battery performance decreases in cold weather, making it harder for your alternator to keep your battery charged. This also affects the performance of the regenerative braking system on hybrids.

In severe winter weather, your mpg can drop even further.

• Icy or snow-covered roads decrease your tires' grip on the road, wasting energy.
• Safe driving speeds on slick roads can be much lower than normal, further reducing fuel economy, especially at speeds below 30 to 40 mph.
• Using four-wheel drive uses more fuel.

How long do you let the car warm up and idle. Many many videos show 30 seconds to 1 minute even in cold weather and get that car into gear. Don't drive it hard until it's warmed up but don't sit there idling forever. This will improve gas mileage.

I'm getting 18-19 mpg at ECO or COMFORT, if I drive a little bit harder 14-15 mpg....only 200 mile at the Odometer, should it improve later?
