How fast should you drive BMW i3?

- What do you do for a living? Bjorn: - I drive cars to find their sweet spot!

[@crazydrifter13]

E spot

You are the only one who does as much testing, it's amazing! Thank you so much for doing this (especially this one because I'm looking into buying an i3), it's amazing the efforts you make to keep us informed! Very interesting test this one, too.

[@Humuku]

Thank you for doing these additional investigative videos. 130 km/h needs too much energy in the i3, my sweet spot seems to be 110 km/h. In warm temperature without AC you can get sub 10 kWh/100 km while driving 90 km/h. In cold weather 110 km/h seems to be the way to go. It also depends on the charger you want to use. Will you reach it? If you are intersted I can try to analyze my Trontiy data collection and plot consumption versus temperature and average speed.

[@DerBlauzahn]

Schleichen bringt nix. Sag ich schon immer 😉 🔨 Hammer it!

[@sveinjohansen6271]

I would say this is more informative test of veichles than the 1000km challenge, as this test gives more data to evaluate car chassis, charging consistency, rapidgate of battery, and consistency of battery depletion. I know its a boring test to do, but its so much data with it !

[@willsbrewery3518]

I loved my i3. So fun to drive and I found it very efficient!

[@richorridge]

I have an i3 in the UK and found this interesting, thanks Bjorn. Regrettably for us in the UK charging locations are not as frequent and when I do a long journey I’m really trying to add factors like lowering consumption to make it to a charge point. So I have a choice of hammer it to somewhere closer and have inefficient charge of 60>90 percent, versus slowing down and making it the next place where I will be down to 10%, which I wouldn’t make it to if I went fast. So many factors, thanks goodness ABRP exists!

[@DanielZajic]

This was a good one, informative. I guess I never get near 50kW charging my i3 because I don't heat the battery enough. It's always peaking at 38kW. As for driving "slow", I can't speak for other drivers, but I'm not in a rush, and it's more relaxing to drive right at the speed limit. Less noise, less vibration, and the most efficient for energy usage. It's also safer.

[@bjornnyland]

So basically you're saying that your BMW is designed for slow speeds? ;)

[@DanielZajic]

@@bjornnyland I see what you did there. 😂 Joking aside, it's a city car, so yes, it is designed to be better at slow maneuvers. Above 100km/h is not the sweet spot, in my opinion. In this way it's very different from the 5 other BMWs I've owned. But it's my favorite.

Best reviewer ever. Kudos for you, Bjorn. What a valuable information. I always thought that 100 kph was the best driving speed on this car for long trips. Also, true that ACC has a phantom breaking sometimes, it’s a bummer :(

[@robsmith1a]

When I had a Zoe ZE40 the fastest speed was to slipstream a truck for extra range, probably 180 miles. Then drink lots of coffee at the 22kw charger. Good job I didn't do many long journeys.

[@davideurenius5272]

I came to the same conclusion with my ZOE R110, not as scientific but found the sweet spot at 100 km/h on the speedometer. And it only charges at 22kW which equals to 100km/h as its quite efficient. Great video Björn!

I also have a 2015 85d tesla which has a max charging speed of about 130kw and average charging speed of about 80-85kw and i also find that the sweet spot it around 110/ 120kmh in the i3 when i go from Geneva to London. once again thanks for the video.

[@robhoitsma3598]

Thanks for all your effort to do these tests! At the end we can see how tired you are, but you keep going! I think you're right: with some numbers you can easily calculate scenarios. Would be nice that one would get the optimal speed in ABRP for the specific trip one is going to make.

[@aljosamarkocic8684]

Can confirm the battery rapidgates when charging if you have "Auxiliary Heating" on and the ambient temperatures are low (sub 5 degrees C). Experienced it several times during winter on longer trips I was taking with a 33kWh i3. If it rapidgates, you'll see this error on the MMI: "Quick charging is not possible. Standard charging still possible. Please note remaining driving range. Have the problem checked by the nearest Service Partner"

[@edwardvanhazendonk]

Thank you Bjorn, great test which showed me I'm wrong, I'll speedup on my vacations 😁 Normally I drive 90 kph but that's because I don't want to charge on my work route (no charger at the office). On vacation mostly 100 kph and switch on Rex to drive around 300km distance and then depending if I can fast charge do a double tank and charge or only tank. This is however with a 6 year old 22kWh i3 Rex, done 145.000 km, battery degradation about 50Ah from original 60Ah, according electrified around 18% less capacity. Thanks again for all your time and energy you put in educating us about EV driving.

[@liv2ska8]

Thank you for making the video Bjorn ! Here in Southern California I have found the sweet spot for commuter speed. Driving 69 mph (112 km) on the freeways here works really well for the i3. Can make good time and go a good distance with some charge to spare. I have the REX on my i3 which I have to say has been a really good back up Incase you run out of EV power. Thanks again, we love the i3 videos 👍😎

[@ericvet8b]

Sweets spot that I’ve found in my i3 is around 65mph (so around 107km/h), so same as what you found. Although I just tend to stick to 68-70mph, in Comfort and stop to charge when I need/if I need it. Head wind makes big difference in this car unfortunately.

[@dfjelddalen]

Good reminder about Europe detours to chargers and gas stations, they can be surprisingly long even for petrol users. 👍😱🏍

[@bartvanhoof6278]

Good test ... it also shows why there needs to be an improvement in charging network (e.g. in Spain, where I live) so that there are more options where you can stop to top up your car when driving at faster speeds (helping adjust for weather/terrain etc. differences you might come across during your trip) ... there's a 20km difference in range between 100 and 120 km/h speed and here it can mean you will or won't make the next 50 kW charger. :) As an example, between where I live and a large city we often visit, which is about 160km away, there's no location that has a 50 kW (or faster) charger! ... that means I can only make it driving slower (about 100km/h) with the i3 if I want to arrive with 10% battery left. Anyway, I'm the type of person that sticks to the max speed limit, so great to hear that it is most efficient timewise.

[@Tehamed21]

The 110km/h consumption is very good to know for "a better routeplanner". The reference speed is there 110km/h. so i can take real world consumption into my calculations. Would love if you will do it with VW Id.3 the same way. Will get my El Born next year so that will interest me alot. Congrats for 200k subs ;)

[@andershjelmare4462]

Excellwnt vid! Decent sound, images and editing! Interesting results fully in line with theory. With speed travel time decreases linearly but charging needs increase exponentially (drag), so there must be an optimum. Your result apply for approx 47 kW charging. A related problem is that my i3 does not accept 47 kW when it's cold. I wish you would investigate that too. I suspect it also depends on which generation of battery...

[@JPetr94]

It's very similar to RaCoBe test of BatteryLife :) In 120km/h run average power output was 27.5kW. I have impression that for best speed the average driving power output should not exceed average charging power (gross, incl. handshakes etc.).

[@baercontact]

Brilliant!!! Thanks for all your testing it helps me know my car better.

So we are even! I copied your 90 km/h range test and you now have copied my RaCoBe Test. Well done my friend. ...I know you did not copy it. You probably don't even know about it. Still, I feel honored. I did this Test with 7 EVs so far. 60km roundtrip with Ionity.

Sorry to burst your bubble, but I already did this back in 2015: kzbin.info/www/bejne/bofTf4d_pc2Ni6c

[@jeanjeudi2970]

@Bjorn Nyland : the optimal speed for this exercice (minimal time for travel at constant speed) can be approached with the following formula : cubic root of P/2a, where "P" is the effective charging power and "a" is the coefficient for aerodynamic friction, i.e. 1/2.rho.S.Cd. That simple approached formula assumes that : 1) all charges are done on your way and are taken in account in your time of travel, i.e. the cacacity of the battery doesn't count, 2) neglects the low speed approach to (and from) the chargers, 3) neglects the efficiency of the traction system of the car, which depends by the way on the speed. For instance, for a BMW i3 charging at 50 kW, the formula gives an optimal speed of 120,7 km/h.

[@esmaeil1981]

Bjørn, Very interesting video! You are solving an optimization problem: min T = D/u + Tc , by changing u, subject to: E = G(D, u, car efficiency, weather) Tc = H(E, charging curve, battery capacity, battery temperature, SOC) where D is the constant distance, Tc is charging time, E is the used energy in kWh, and u is speed. If we knew the functions G(.), H(.) we could solve it in Matlab :)

[@dos585]

Sometimes with my old Hybrid car i drove at maximum Speed 180 on german Autobahn. Around 100km From Munich to Deggendorf and around 50 km are country roads. The average Speed was only at 108 zo 110km/h. So i decide to go around 110kmh maximum. It costs only 5 min more. Same with Renault Zoe ZE 40 (110km/h) summer 160Wh and winter 190Wh the Heatpump needs around 1.5 to 3kWh Than its 200Wh. Thanks Bjorn I really like your Videos and the sometimes awesome landscape.

[@tobiasstaermose]

I guess it also depents on fastcharger availability. In e.g. here in Denmark i often find that "all" the fast chargers have cars waiting, so that it would be a gamble to just fast and stop at every charger.

[@pilotandthecity8527]

Cool test Bjorn. My nxt long distances trip I'll do it with 125km/h. Let's see what comes out of it. Amazing you take the time to test it. Compliments.

[@artokiiskinen1058]

The BEST resource for ev real world tests is TeslaBjörn!!! I keep telling about you to everyone

[@frederikjmx]

The optimal driving speed reduces to 110 when the detour is slightly longer, you hit a red light or initiating charging takes longer. So I added 3 minutes to the total time and calculated the average speed: 62.9 - 67.5 - 68.6 - 67.9 Therefor 110 km/h is the sweetspot in those conditions

[@rychu1978]

You should drive the same distance Bjorn but then you would have to load twice, so the average speed of the ride would drop and the time of the ride at different speeds would not be so different. If the range of the car would allow you to travel at a speed of 90 and 120 the same number of kilometers to get to the same charger, of course it is worth going faster. Charging won't take much longer than the profit from driving faster.

[@bjornnyland]

Nope. Driving the same distance is not correct. The slower you drive, the longer you can drive. And the less charging breaks you need.

[@allisterbullock213]

Very interesting tests, more of this please.

[@ndc5544p]

Thanks Bjorn for this awesome test!

[@CoolSilver]

It makes sense. You might stretch the range by going slower but it isn't worth the time lost. Being at a higher SoC when arriving might ruin your charging speed and waste even more time. Hopefully not billed per minute on a 150 kW charger when a 50 kW will do just fine. Talk about noob mistakes that are found in articles.

[@LilaKuhJunge]

It is just me, but I like the i3 for travelling. I won't drive more than about 600km a day - and did not with my previous gas cars. I will start with a full charge and pre-heated battery and cabin, go for 150km, have a coffee and charge to safely reach my lunch destination in about 150km. Then I will have a decent lunch/tourism break while charging to 100%, then do 150km, charge to safely reach my destination buy stuff I need at my destination. Then I will do the remaining 150km. I will use ACC and Eco modes wherever possible. Best speed is around 120km/h.

[@Vtech-bp1fj]

Really interesting test. Who would have thought that the best speed to travel in a Tesla is over 100mph. Will shock fossil drivers. Critical factor obviously is to have lots and lots of charging points so that you can simply stop and charge whenever a need arises.

But you can get the same information by using A Better Route Planner and put in different speeds to create the data table, I did this for the 380 mile trip I take every month and found that the quickest trip in a Tesla Model 3 would be at 101mph! ABRP can give you this data in a few minutes, but would make for a dull video. :-)

I know. And that's what this video was about. A simulation based on several tests (120 km/h test, battery capacity test and charging test) is good enough.

[@MrFipsomat]

Thank you for this very informative test!

[@krisany3670]

Given the results though, I would probably try to stay around 100 for this car. After that the avg speed incl charging doesn't really increase much and I def prefer spending time at the wheel vs at the charging station. It might also mean fewer charging stops per trip which is a significant comfort factor.

[@tucsonor]

Low SOC strategy, practice that on my 2021 Leaf. Max SOC for it is 60%, so a lot of charging stops. But the fastest way to drive.

Very interesting test. Thanks. I prefered a slower speed, 90-100 at 110 km/h highway back when I still drove (had to stop due to my muscle disease 😔) I did not get so tired at slower speed and you can enjoy the ride more. It's also safer (unless you drive so slow that you create dangerous situations 😀)

Yes, I have the same. 5 years ago, at least, the question for me in the UK was what speed do I have to drive to be able to reach the next charger? Less of an issue now the number of chargers is so much higher. Or, for some trips, if I drove slowly, I thought, I won't need to stop; if I drive fast, I will. Then the time difference would be much larger. The other difference for Bjorn is that in Norway, the chargers all work, they're fast, and there's lots of them, while in the UK there's more of a chance of charging delays. :-)

While I am against unlimited speed on Autobahn, a general speed limit of 130 km/h should be considered.

Good Morning Bjørn, your Reports about the i3 are just great! I’m a little confused by BMW’s way into future.

Its not so easy to make small cars efficient.....to provide enough room and easy access they made most of these cars higher (I3 is 158 cm, Zoe is 156 cm) which is not good for air resistance......Mini is lower but it also has a smaller battery, a bigger battery there would result in a 2-seater with hardly any luggage room

Isn't the i3 designed as a small mega city car, optimized for speeds around 50-80km/h and short city ranges? Sure it cannot compete with (larger) cars designed for longer trips, but it very well can w.r.t. other electric city cars.

[@SteveDaviesCPT]

I guess it will be excruciating to do the test - but best speed to maximise range? (It would be in an aircraft POH...). Here in South Africa there aren’t that many fast chargers and they are 150-200km+ apart on the national roads. So it’s a stretch for the 42kWH i3 which is the only vaguely affordable EV really sold here. So how slow do you have to go? Let’s say 5% battery degradation - so to do 200km on 85%-10% means 149Wh/km which is pretty frugal. From 100% means 179Wh/km which should be do-able without too much fuss. We also have quite strong prevailing winds in the southern part of the country where I am which could turn these legs into nailbiters...

But shouldnt you test this and drive the same disctance on different speeds? Because when driving on a higher speed it increases the consumption so you need to charge more often (or longer).

No, at lower speeds, you can drive longer on each charge.

@@bjornnyland yes, correct. But when you for example drive every time a distance of 100km, and redo that at different speeds.

This is fine forhighway driving, but for eg me which lives in Bergen/Norway the longest highway stretch is 12km at 80km/t. so here we go slow regardles. I guess these tests are limited to where you have a good supercharging network, but like in western part of Norway where super chargers like ionity is so spread around that you cant even get to next charger due to tall mountains,its a different approach to know when and where to charge up.

@@sveinjohansen6271 But to test what is quicker, you need to do the test with a fixed distance. Only then you can see the effect of the shorter drinving time versus the longer charging time.
