Got a 2018 Niro LX hybrid a little over a week ago. I’ve been hypermiling cars for a long time so I was eager for a chance to see what I could get this one up to.

The test run was only 10.3 miles. 2 miles were in a 30 mph zone, 3 were in a 40 mph zone, 1/2 a mile in a 50 mph zone, and the rest in a 45 mph zone. The speed limit was reached in each zone. 1 stop sign and 9 stop lights on this trip. The battery was one tick below 3/4 charge at the start. The car has just over 1700 miles on it and tire pressures are too low at 32 psi.

91.6 mpg average on this trip. That is with myself in the car, and my wife, and our daughter, and my mother-in-law.

Seven of those miles could have been on battery if you started with a decent charge. Not sure I see the point of documenting short trips, it is your lifetime average that truly counts. You are also dependent on an electronic algorithm of dubious accuracy on short trips (and long trips too). But if you enjoy such exercises, well I'm happy for you. I'd be interested in some comparison of how you do with the Niro versus other cars you have owned.

Ya you really need to do it with a full tank of gas worth of driving, otherwise the results will be all over the place. There are some drives where I've only gotten 15mpg. And others where I've gotten 200mpg. What matters is how far you can go on a tank of gas, and it's really unlikely you'd get 90+mpg over the course of a whole tank. Probably more like 60 if you're hypermiling, or 45 if you're driving normally.

Here are some other vehicles that I have owned and what I have gotten out of them;

2014 Mitsubishi Mirage ES. 54.5 mpg
2006 Chevy Colorado LS. 34 mpg
2001 Mitsubishi Mirage. 45 mpg
1991 Chevy Cavalier. 42 mpg
2017 Ram 1500 Hemi 4X4. 25 mpg
2012 Honda Civic EX-L. 45 mpg
2003 Dodge SRT4. 36 mpg


Yes, I am fully aware that measuring the fuel economy over the span of a full tank of fuel is a better indication of how well the Niro will do. This 91.6 mpg is 50% better than I have ever gotten on any other vehicles so it had me giddy with the possibility of what could be. Right now, after 30 miles of driving on that tank of fuel, it is averaging 67 mpg. I am confident I can increase that number in the future but for the next few months it will be difficult to do so. There is major road construction going on right next to my home which is decreasing the mpg. Once they are done, jack rabbit starts will not be required.

Best I ever got out of a tank (701 miles) was 58.70 mpg (displayed mpg was pretty close at 60.1). Leisurely trip, lots of secondary roads, never exceeded 65 mph. Summertime. Briefly tried a few hypermile techniques on that trip, coasting up short steep hills and drafting, but only a few miles, not enough to affect total mpg over 700 miles.

If you have the patience (and space) to keep it to 50 mph, you will exceed 60 mpg fairly easily in good conditions. Or try a trip on something like the Blue Ridge or Natchez Trace Parkways with low speed limits.

I would love to see someone get those hypermiles around here. Woke up this morning to that Polar Vortex where it dropped to -25c ( -13f ) and a daytime high of -14c ( 6f ). The Niro started flawlessly, but you have no choice but to run the defrost on the car as your breath will turn to ice on the windshield inside the car. That means the engine is running no-matter-what. I turned it on and left it running for 5 min while I scraped off the ice from the outside windows, then turned on the heated seats and stearing wheel and proceeded to drive. it still took 10 more minutes of actual driving before the engine was warm enough to actually start blowing heat into the car. Up until that point it was doing the low level blowing using the electric heat module that has shown up in several threads here. That gets warm enough to help keep the windshield inside the car from fogging up, but not enough to give of any meaningful heat.



I would seriously doubt that anyone could get away with even close to the 50-60mpg that has been talked about here. I was qute happy not to turn into a block of ice and actually got closer to the 23mpg mark for the drive that I would rather not have had to make.

I've wondered about that, too.

I'm guessing it wasn't driven "normally". As in, if we drive a Niro across the US the way a normal person drives, we'd probably get something more like 50 or 55mpg.

These guys were probably hyper-miling to the extreme - they may have stripped weight from it (no tire kit, no back seat possibly, etc.), they may have kept the fuel tank almost empty the whole time (by adding another gallon every 75 miles, while in motion, by someone in another car), avoided ALL stops (by having food and water passed to them through the window by another car while in motion, using a travel potty, etc), stayed entirely on highways with no stop signs, traffic lights, and construction, chosen a route that minimized driving uphill, drove during the ideal time of year to avoid extreme weather and have the ideal temperatures, maybe had a dedicated vehicle always in front of them that they could draft, and they probably had another "scout" vehicle or two in front of them to make sure there was always an unobstructed path, and to report changing conditions ahead so they could accelerate or decelerate precisely the right amount at the right time in advance.

They could have done any one or more of those things, or maybe even ALL of those things, for all we know.

I appear to have rather bad timing on my return home to Ohio on Sunday where the predicted temperature that night will be -9F. I haven't seen those temperatures there since I was a kid, say fifty years ago.

I'll be driving the Niro in the morning too, at least if this winter storm does not derail my flight. Should be interesting to see how it fires up in that temperature after 5 weeks parked!

The side of driving a Niro in the cold is that everything is also relative. Sure you are getting worse off fuel economy from the highs of driving in much warmer weather, but relatively speaking, so do the ICE only vehicles as well. I must keep reminding myself that with my 2013 Ford Edge, in the warmer summer months I would get an average of 9-10 L/100km, but as soon as winter hits that number easily drops down to the 12.5-14 mark. When you look at those numbers, does it really make sense to complain when you are getting 6-7 L/100km in winter? sure it is not as good as the 4.3-4.9 that brings a big smile to your face, but it is still half of what I was getting on the gas only guzzler. And that was not driving very aggresively but not to the level of hypermilling though.

cockedandglocked: Wow, I would have never thought of some of those "tricks", kinda cheated if that is the case. Maybe they wore diapers or had a bottle handy to pee in so they wouldn't have to stop for that! ;-)

I'm gonna do a bit of searching to see if their techniques are available anywhere, I'd be interested in reading about it

I'd be interested to know, too. I doubt they used ALL of those cheats, but I guarantee they used at least some of them. It's the only possible way they could average 75mpg for 3000+ miles, in a car that's EPA rated at only 60% of that.


One other thing I thought of, they could've had special tires that had extremely low traction and extremely high inflation pressures.

It took a little digging but I managed to find a couple of links with some info about the record run. They are rather lengthy but interesting reads:
2017 Kia Niro CUV Sets GUINNESS WORLD RECORDS Title for Lowest Fuel Consumption for a Hybrid Vehicle | CleanMPG

"New York City, New York -- Arriving at New York City Hall in downtown Manhattan, the 2017 Kia Niro officially received a Guinness World Record® title for the lowest fuel consumption driving across the USA from coast to coast for hybrid cars. The new record-setting mark is an incredible 76.6 mpg.

Achieving this lofty result did not occur in Kia's most efficient Niro trim - the FE trim - but in one of the projected highest volume trims, the slightly less efficient LX variant. The time of year was also a challenge as the Niro was driven across the continent in December, far from the peak efficiency period and heat of summer making the Guinness World Record® even more noteworthy.

The Guinness World Records® setting 2017 Kia Niro LX with Kia brand and sponsor logos from Shell® and ScanGauge®, was driven by Wayne Gerdes of Carlsbad, California, and co-driver Robert Winger of Williamsburg, Virginia. They departed Los Angeles Calif. on Sunday Dec. 4th and reached NY City, NY on Sunday, Dec. 11th, having traveled from Los Angeles City Hall to New York City Hall covering 3,715.4 miles using only 48.5 gallons or 4 tanks of gas. The vehicle was not altered in any way for the attempt other than the addition of (2) full size mounted spare tires and (2) Garmin® portable GPS units."

Thanks for posting that link. It is a lengthy read, but worth reading. Among other things, he states that with two people and extra gear, they had 700 pounds in the car (including two mounted spare tires). They had multiple strategies for maximizing fuel economy, but it sounds like one of the primary strategies was something called Driving With Load (DWL), which amounts to trying to keep the instantaneous fuel economy reading at a constant high level, primarily by keeping the throttle position constant instead of the speed. They also had to deal with cold weather and headwinds, etc. There are several other good tips in there that are worth reading.

Well now the forecast is for -14F. I'm just back and shoveled my driveway. Didn't turn the car on, but the 12V battery did not need to be reset. We will see tomorrow morning!

The tire pressure did drop 4 psi in five weeks, likely most of it due to a 30 degree drop in temperature - currently 11 degrees here. Should have waited until morning with another 25 degree drop, but I figured it would just be too cold for that chore then.

keeping the throttle position constant instead of the speed.
And keeping max speed in the sweet spot, 35 to 40 mph.

It's starting to make more sense now. If they kept the throttle at a precise position most of the time, say 5% throttle, then that MPG is very realistic. But the drive would have been miserable. I would imagine the car was going about 40mph (at most) on flat roads, and on uphills it may have dropped as low as 5-10mph. Basically, the car was just going whatever speed it goes with that specific amount of throttle input.


The trip took 7 days, and since they had 2 drivers I would assume they took turns behind the wheel and thus didn't make any sleeping stops. This means they drove 530 miles per day, and assuming 22 hours of driving per day, that's a 24mph average speed.


I'd like to see the figures for how many cups of soda got thrown at their car for holding up traffic.

Montreal did not have this kind of "Blizzard" snow storm since 1922... -35c with wind-factor (-31f) and 25cm (~ 10inch) of snow on the same day!

Yesterday, The PHEV started #1 on EV mode for 5 km, and needed heat.. so i made in HEV mode, a good 8.5L/100km (33mpg) for a total of 30km (15 miles) ride. awesome.! :)
