Bjorn Nyland Conducts Efficiency Test On Ioniq Electric, Tesla Model S, X – Video

APR 15 2017 BY MARK KANE 23

Bjørn Nyland with two other EV owners conducted tests of the world’s most efficient EV – theHyundai IONIQ Electric, with two Teslas – the Model S 70D and Model X P90DL.

Consumption test on Hyundai IONIQ Electric, Tesla Model S and X Tesla (Bjørn Nyland)

The result of the encounter was easy to predict, as the IONIQ simply needs least energy to move.

However, the difference to Model S are not so big at higher speeds.  Bjørn discovers the Models S uses just 13-14% more energy at 120 km/h (75 mph).

At lower speeds the differences are more in-line with the weights splits.

The  heavy Tesla Model X (2,600 kg) needs 50 to 68% more energy, depending on speed and the test cycle.

Consumption test on Ioniq, Model S and X

We all know that Hyundai Ioniq is the most efficient EV. But how efficient is a Model S 70D facelift? It was actually pretty close.

The IONIQ is closer in shape to the X than the S, and is 50% more efficient than the X on the highway. Wow.

Actually, all three cars share the same CD of 0.24, so it must be that the X just has a much higher frontal surface area. Still, I’m fairly shocked at the difference.

Cd is relative to frontal area.
A barn and a sugarcube have about the same cd, but very different drag force.

+1. Exactly

Well seeing as how Model X is 63% heavier, I don’t think it’s any less efficient, just… heavier! So more consumption.

It’s like saying a hatchback is more efficient than a pickup truck… well obviously!

Actually that would make the Model X MORE efficient per kg. Ha!

Trying not to be a jerk but I am. I can not make it threw a bjorn video. It takes he likes forever to say anything it drives me crazy sorry I know I am a a$$.

Oh sheeet!
There is nothing wrong with you, his style, is well, ponderous at best.

I will never watch another one of his videos. I love that I can always read a synopsis here.

Disagree completely, 100%! I love his videos, am addicted to them! Sheeeet, that is right. By the way, watched a pair of Swedes doing a video of the Ioniq and they both said “Sheeet…a cop car”, so obviously that has become Bjorn’s calling card. Again, though, I love them.

Converting his data, Ioniq 75MPH eco=3.58 mi/kWh, 56 MPH=5.21 mi/kWh, 43 MPH=6.67 mi/kWh. I’m curious how it’d do at 70 MPH, which I got 4.4 mi/kWh (227 Wh/mi) with SparkEV.

Assuming 0 MPH=0 mi/kWh and using 3rd order polynomial fit, I get 3.81 mi/kWh at 70 MPH. I need to get my hands on Ioniq…

These are VERY impressive numbers, i will try to test one as soon as they become available.

If you’re in Santa Monica area, see if you can get waivecar.com. They supposedly have a deal with Hyundai to have free 2 hours of SparkEV and Ioniq. Not sure if Ioniq is available, yet, though.

Though there’s a big sign on top of the car, it could give rough numbers.

I’m going to try that 70 mph test in my 2017 i3. I was trying 80mph, but kept coming up on traffic and had to abort. So the Spark got 4.4 Miles/kWh at 70mph, and what was your total test distance?

SparkEV

If you try to test near LA area, it will be impossible to keep 70 MPH, let alone 55 MPH. I got _very_ lucky one day in OC, so I cruise controlled for about 55 miles (about 70% of total battery capacity) and slight elevation gain. Details are in my blog post.

Remember that the Ioniq and X had winter tires and S summer tires. The wh/km should go down with summer tires on the Ioniq and increase the difference with the S.

Why do all three use more power at 75 mph eco than normal?

Yes, I wondered this as well. It doesn’t make much sense! Perhaps the data has been muddled up by mistake?

Keeping the eco logo lit up on the instrument cluster takes more energy 😉

Hyundai employs a permanent magnet AC induction motor. These have reduced excitation losses to conventional 3phase AC motors. Tesla chose not to manufacture it’s own motors this way for various reasons. Costs, Rare Earths Supply/Market Volatility, Control of Rotor Excitation Levels for Regenerative Braking, Motor Cooling/Power Output.

Such a long video, and they don’t even tell how they measured the energy consumption. If it’s from drive computer it’s not reliable and doesn’t include charging efficiency. And they have different type of tires for each car (summer, winter without studs and studded winter tires). I don’t think this data has much value.
