The EPA test isn't equal, it factors in the efficiency of the charger. The Leaf speedo is known to read a bit high, as much as 10%.

Anyway, it doesn't really matter for most people. The difference isn't large, things like the cost and shape/size are more important.

I've just put 1600 miles on a New Ionic. In 5 degree temperature at up to 60 mph motorway I got 147 miles. Shows 4.9 miles/kWa on the trip. With regen off it coasts really well. It feels like 90% of the braking is regen and I'm sure this will be more like 160-170 in the summer. Not sure how far a leaf goes on a full charge but this is quite good. Most of my journeys are sub 100 miles so range issues are minimal.

That is much better than my 30kWh Leaf.

I made a computational model to approximate the range numbers we found and predict the ones we did not find yet. The model assumes a linear dependency of range on temperature, and a dependency of range on speed that is a combination of linear and quadratic. Below you can find the table as was found earlier followed by a table with the model outcomes. For the same tables in miles, see next post.

As our available population of cases shows a lot of variation, the model naturally deviates from these individual cases. For example, in some of the high temperature cases concerning the Jeju Island rally they have selected a very good hypermiler as driver, whereas in Bjorn Nyland's Winter Tests he did not try to drive in an economic way, and sometimes used the sporty mode, and besides, he had to fight very bad weather conditions in the second part of his trip.

Due to this variation over the different cases, the average deviation between model outcomes and reported data over all cases is about 20 km (12 miles). Most of this average is determined by the most extreme cases. If two or three most extreme cases are left out (by considering them as socalled outliers), the average deviation between model outcomes and reported data becomes about 10 km (6 miles), which seems reasonable.

Reported range numbers:
-------------km/h
--------------40-60---------60-80--------80-100-------100-120-------120-140-------140-160
°C -10--5-----X-------------159-----------143-------------X----------------X----------------X

---20-25-------X--------------X--------------X--------------X----------------X----- -----------X
---25-30------351-----------339------------X-------------220--------------X----- ------------X

Range numbers as outcomes of the model:
-------------km/h
--------------40-60---------60-80--------80-100-------100-120-------120-140-------140-160
°C -10--5-----182----------162-----------137------------107--------------71--------------30

The sport mode is about the same as the Leaf's eco mode. The eco mode basically forces you to hypermile.

Seriously, that's nonsense. I only had a relatively short drive in the Ioniq, but Sport mode is a world away from the Leaf's Eco mode.

I had a fairly long drive in the Ioniq and the sport mode is not very sporty at all. Compared to the Leaf in normal mode it's not in the same league. Slower off the mark, and much slower accelerating from 50.

When I stopped at the half way point on my test drive I actually faffed around with it for a while making sure I had it engaged properly. Sure enough the speedo changed from the annoying thin little dial to a slightly small numeric display, but it still wasn't very quick.

Seriously, they tuned that car to be ultra efficient. The sport mode is about the same as the Zoe in normal mode.

Looks like a great vehicle. Just a shame they are priced out if he market high. Kia did this well in the Soul marketing and it bombed.

To make a good start with 2017 I made a Google Sheet to collect experienced ranges or efficiency numbers for the Ioniq EV. Everybody can use this link to add rows with his or her experiences with range or efficiency numbers. Note that real ranges are meant, not the car's displayed expected ranges.

Based on such data we can get a better idea of the car's real world efficiency and range.

Have a good year, with more EV and less ICE km's or miles!

These schemes give some insight in how the Ioniq Electric's range varies with the average speed and the temperature.

New update, now for temperatures as low as -10 and -22 °C, thanks to new reports from Norway, some for temperatures from 21 to 25 °C from South Korea, and some for temperatures from 1 to 5 °C from the UK.

-------------km/h

Note that you can click on each of the range numbers to see where it was reported.

For those accustomed to miles and Fahrenheit or Celsius, here the same scheme in these units:

Great work Jan on the data collecting. I'll start keeping my more details logs of temperatures and dates. The miles per kwa and distance are saved on the car and I'll update your google sheet On my next motorway stop. I've got 3000 miles of test data already !

I need to find a leaf driver for a drag race. Sport mode with traction control off is messy. Complete slippage of the front wheels below 40mph in any sort of bend on moist to wet road surface. Pick up from 45 upwards is less surprising but still more than enough.

Jan, your table is not readable to me:

I see. It all depends on the device you use. On my laptop the layout is fine but on a smartphone it turns out there is no space enough for all columns. I could make a jpg of it but then we cannot make the entries clickable. What would be best?

Below you see the jpg:

Where are you based? I drive a Leaf and my PCP expires end of Feb. Ioniq is top of my short list but would like to know if I'm gaining or sacrificing performance with such a move.
