The question I have is is: can the Inverse Square Law predict the range for the other speeds, and be a useful thing to use to estimate your range at various speeds? (For those saying "Inverse What?": the car's a 3D object, but it needs to push air out of the way of its front at speed and that front of the car is the equivalent of a 2D face pushing into the air. The theory is that a car going twice as fast as [base number] km/h will need four times the energy, 2², and three times the speed will need nine times the energy, 3². From that you can work out fractions of the differences. 150% of the base speed is 1½², so the energy to push the air aside is 2¼ times the base amount. If the base speed is 100km/h, then 120km/h should need 144% of the energy to go the same distance that was achieved at 100km/h and should only go around 69.44% of the distance on the same battery (and the reverse is true too - if the base speed is 120, then a run of 100 would use 69.44% of the 120's energy and would go 1.44 times the distance). 140km/h would need 196% of the energy that 100km/h needed to go the same distance and so should only go 51.02% of the distance that 100km/h was capable of with that charge.) Science class over. I'll put what the predicted ranges should be once I get to the part of the video with the 100km/h range, then type in the actual range achieved, and how much my prediction was off. The time stamp for the results is 8:49 - time to plug in the predictions and the actual numbers. 100km/h = 744km range. 120km/h = predicted 69.44% of the above is 516.63km, real world range is 519km, prediction is 99.54% accurate and you go further than the prediction. 140km/h = predicted 51.02% of 100km/h is 379.59km, real world range is 405km, prediction is 93.72% accurate and you go further than the prediction. There would be other variables in play (friction of the rubber on the road, efficiency of the electric motor at various speeds, etc.) but it works out. Using the Inverse Square of one speed to predict range at other higher speeds is a very handy ballpark way to guess how far you could go at higher speeds, and gives you a small buffer of reserve energy.
@@wizzyno1566 "The question I have is is: can the Inverse Square Law predict the range for the other speeds, and be a useful thing to use to estimate your range at various speeds?" Predict. Estimate. "There would be other variables in play (friction of the rubber on the road, efficiency of the electric motor at various speeds, etc.)" Friction (as in heat). Efficiency of the motors (as in mechanical). I mean it was right there, flower!
Well, with my Ioniq 6 AWD I have a range between 570km and 580km and I think this is really great given its weight and battery size, all when I drive in Eco mode, so basically only with the rear motor.
@@NonstopDrivingReviews I love the car. It drives so smooth while there is always the potential to unpack its power (AWD). It is my daily drive and I am completely satisfied. The only hiccup it had was with the satnav software update that makes the Bluelink stop (but that was also in other models), a bit of google search and a soft reset did the trick.
Interesting. As someone that does a lot of fast Autobahn Kilometers, i'm starting to look at more information on the EV side of things (personally, i wouldn't buy an EV, but that's another thing). The fact that you still get 300 Kilometers driving 190 km/h is still pretty poor. I recently got the Mazda CX-60 with the new inline 6 Diesel and it does amazing (around 8 l /100 km while keeping it between 160 - 210 km/h, giving me a range of ~ 700 km), but i cant help but wonder what one of those new Diesels could do in such a body...the CX-60 still has a cW of 0,28 (which is impressive for a big SUV, but still...). Comparing the 10,4 to the 25,5 is still 145% more.
Thanks so much for your insights. Hopefully we can get our hands on a CX-60 in the near future. Really love the engine that they put into it. Where getting our first Mazda at the end of the month but only a Mazda 2 Hybrid.
Thanks for the kind words! Yeah 120 is the sweet spot but this car is really good at any speed with its aerodynamic. If you enjoyed a sub would mean the world
Imo a technical a very good car, but i don't like the looks from the outside as wel for the interior. The outside gives me the feeling as if it's already outdated, i do like the rear wing and the 2 led bars, but the grey things on the rear bumper.... really Hyundai😨 Impressed by the low power consumption with lower speeds, and interesting to see that at highest speed it doesn't really make a difference compared to other cars at almost the same speeds. Thanks again for this very good video, looking forward for the VW Passat and maybe the new Tiguan?
Thanks for the comment 😊 Passat will be uploaded in 2 weeks (very interesting consumption on that car). We will definitely ask for the new Tiguan as our next VW Modell which will be later this year as we already have the ID.7 Planned
My Audi 2018 A4 Avant 2.0TDI can get over 30kpl in the daily commute. A trip from Denmark to the South of France and back was about 5000km and I drove at the maximum allowed speed, and the average consumption was 19kpl. Why would I change to EV?
Awesome review. Would love to see similar test with Ionic 5N.
Thanks ! Already in progress but will take a time before we get the car. Make sure to leave a sub if you enjoyed

Yeah, lets just ignore mechanical and heat losses then...

Great to hear from someone who drives it daily. Thanks for the comment. How do you like the car in general ?

Great video. So the conclusion is : drive the car at 120 Km/h to get the best of the two worlds.

Unfortunately there is a threat to us all and we all need to stop burning fossil fuels as soon as possible
If you test one Ioniq 6 you'd know
Do not change then. EV is not for everyone. 👍🏻
A car design that is so close to being good but is just wrong.
that basically summed up my view of it :)
