    There are problems you can wrightly list with both telsa/ipace. Both are exspensive,more so with model x,especially maintainance and ipace using far to much juice.Theres alot of very good reviews off IPACE thou,and Ive read All of them. It boils down to this.Dont buy either Telsa or X/ipace.Buy kia Niro or Hyundai kona.Both for price and it's range ECT ECT,absolutely destroy the other 2.

    Great review Bjorn. Being a Brit I'm slightly biased to the i Pace so I guess its not bad for JLR's first attempt but its not a Model X as far as performance goes. However I've driven a P100D L and performance made me use the F word when flooring it in ludicrous mode but I hate the American interior and trim. (they wouldn't let me take the model X our) Hmmm
    Waiting for the Land Rover EV….

    I heard that every I-Pace that will be delivered to customers will get a major update. I still hope that people like you (the field testers) will give the input for improvements that will be updated at delivery..

    Hi Björn, thank you for investing so much time to get the data.
    I know how time consuming this is, not only because of my test with the I-Pace within I record the first charging curve at Rödekro at IONITY 350 kW charger.
    You are right. The sweet spot at 130 km/h is a very good news. I was wondering whether it could be round about 100 km/h.
    Because of IONITY will place each 120 km a HPC you have to charge at every single station, good to know that with 130 – 150 km/h you are able to drive to the next station (114,9 – 139,4 km distance).
    We also have to keep in mind that there will be a lot of other different HPC charging networks like Ultra-Charge, Mega-Charge, Fast-E and so on so we will have a lot of different possibilities in future to charge.
    But you are right. The I-Pace driver has to survive the next 1 – 2 years with lower speed at long distance rides.
    I hope we will see us soon in Germany.
    Best wishes
    Grüße Dirk from EV-Car-Vlog

    Nice work, but why does no programmer creates a tool for all the BeVs, to calculate the optimal speed under the known todays temperature, the hight-profile of the route, the actual and expected traffic, the temperature of battery, the charge-profile of the specific battery and the known charging-Gid and it's status.. That would be of more interest for the unexperienced farmer or my mum as a driver than autonomous driving or lane assist or 3D-Camera-Views. "Tell me the optimal speed and charging location for my specific BeV".

    Thanks Bjørn, very informative video. It's essential to show people that EVs aren't less convenient than ICE cars, just have a slightly different usage model, and how to make the best use of them.

    Thank you Björn for your very exhausting test. It helps with the decision to switch to an EV. Especially in Germany not so easy. Right now, the Audi e-tron is at the top of my list of European EVs. But maybe the Model 3 comes even faster than expected to Europe.

    6:03 Wait a second, i don't get it. Why does the charging and detour time increase ? And what the heck is this factor ? If you charge always 60 kWh, it should always the same time, no ? Same for the average detour time.
    I just did another spreadsheet and get same average speed without the factor.

  9. Simon Canfer

    Love the data! I used my Ioniq electric figure for 70 mph (232Wh/mi), and using a 50kW charger I think the Ioniq comfortably beats the iPace on average speed. That car is just sooo thirsty, I hope they can improve on it. However – I think we are both omitting any fast charger losses, I will try to measure this for the Ioniq soon.

    That graph at 10:00 is such a good idea – and a great way to compare various vehicles fairly, taking into account multiple factors, specifically all the factors that go into the charging times and how that affects your overall trip time.

    I created a spreadsheet file by which it becomes clear how Bjørn has calculated these numbers (tables at 6:00, 8:00 and 9:30). I can 100% reproduce the I-pace values exactly and understand how they have been generated. I also approximated, with the same method, the three Tesla-X values from 9:30. The spreadsheet also contains the comparison diagram from the video at 10:12, and an extra spreadsheet by which everybody can record one's own individual charging characteristic for one's own EV/charging station combination. This way, everybody can generate these curves for the own EV now! I created the spreadsheet with LibreOffice (*.ods format) and also exported it from there to MS-Excel format (*.xls). Here are the two links: Hope they are not corrupted when opening with MS-Excel, in LibreOffice they look perfect: ODS format: "https://www.dropbox.com/s/kv8ookv6yom8txn/Long-Distance_Travel-Speed_Calculator.ods?dl=0" and XLS format: "https://www.dropbox.com/s/1k60zg52j9dm71k/Long-Distance_Travel-Speed_Calculator.xls?dl=0" (Spreadsheet files are plain simple, have no macros or advanced stuff at all).

    NOTE: The energy consumption that occurs during the little detour towards the charging station (Bjørn assumed avg. 3 km detour per charging stop) is neglected (i.e. assumed as zero) in Bjørn's mathematical model (and hence also in my spreadsheet). I think that's ok! Because, that effect is really negligible. In my spreadsheed I added a field called "Time for (un)plugging the charging cable" that I set to "0 minutes" by default to be aligned with Bjørn's model. The user of this spreadsheet can put another more suitable value here, as desired, and that value may also contain the (very little) extra charging time needed to account for the energy consumed on the small detour.

    I'm doing a test today with my Kona to workout impact of regen level on consumption on straight and level test route. (How parasitic induce load will reduce efficiency) have you studied this on any of your reviews?

  13. MiccaPhone

    WONDERFUL!!! This is exactly(!) the kind of information I was looking for after having seen some other EV reviews. Highly appreciated! Crucial and relevant info, absolutely appropriate technical/mathematical approach, and I appreciate the (non-negligible) time you took to gather and evaluate all this! These kinds of curves should become standard for professional EV testing… Keep up this awesome work, greetings from Germany to Norway.

    Looks like such a nice car but the consumption/range will be a real issue here in Australia. I was thinking about one as an alternative to my Model S 100D but with that consumption and without SuperChargers, it just won't be viable for the Melbourne/Sydney (900Ks) run.

    Awesome video! I thought that I could do quite well driving long distance with an electric car but now I know better. Yes the I pace is very thirsty, I know. Aside from that:
    IF we had the ionity fast chargers it would mean 30 minutes break for every hour of driving. That's ridiculous!
