Don't know if anyone noticed the difference. Chill mode's regenerative braking is more "smooth". This is the main reason I use it. In standard mode if i release the gas pedal the "stopping" is much quicker, vs in "chill" mode. End result may not matter much to the driver, but is a HUGE difference to passengers. My wife will literally throw up when I drive in "standard" mode while "chill" mode is more bearable. Sure, I can use "standard mode" and when letting go the gas pedal, let go super slower and sensitive. But that's such a big hassle and big effort, it takes the joy out of driving the car. So, CHILL mode is just more smooth, for the passenger. Anyone else feel the same?

[@robsmith1a]

I found ECO mode on the Zoe made no difference to economy (assuming I drove at the same speed). I never used it because it killed the acceleration on an already slow car and the heating didn't work well.

[@amosmoses9829]

Presumably the only difference is that chill mode forces you to drive more economically. Physics is physics. Nothing prevents you from driving as economically without chill mode.

[@loneskullkid]

If you drive in sport mode like chill mode you will get the same consumption.... no shock

[@HikaruSorano05]

@@loneskullkid If it is like in the fossils, the accelerator response should be sharper, hense higher consumption. The ECO mode i fossils also absorb the little movements of the foot on the throttle, and therefore, less consumption too. Would it be possible that in the EVs we have a similar feature?

[@bisitis]

I believe it depends on environment where person drives. I am quite sure if it would be checking acceleration and deceleration, there would be some difference. E.g. doing 150 times from 0 - 60 with & w/o chill mode, there would be some difference, as I believe there would be less heat loss on battery due to pulling higher power on sport mode. Of course, if you do only highway driving and accelerate only few times, there will be no difference whatsoever. It is completely same logic with ECO mode in other cars...

Can you do the same test driving in the City? Using constant speed on the high way does not make much sense to compare Chill / Sport.

Chill mode help me preserve my studded tires and apply torque really gently on slippery surfaces. But yes, right foot education can do the same.

[@bjornnyland]

If your throttle foot only works in binary, meaning WoT and no throttle, yes.

[@fredrikeklund9663]

The power-loss in a electric motor is proportional to the current squared (I^2) and consequently the motor torque squared. The power-loss in a battery is also proportional to the current pulled. The theory will predict no difference in consumption when driving on highway since keeping a steady speed at highway require the same tourqe and consequently the same current from the battery, chill mode or sport mode. The difference will show in city traffic because the chill mode will make your right foot "less heavy". Being a aggressive driver will increase your consumption. If you already are driving carefully the chill mode will not affect your consumption. Another conclusion from the theory are that avoiding regenerative braking for the benefit of coasting will lower your consumption.

[@TeslaHere3]

Agreed, I use Neutral for coasting to lower consumption sometimes.

[@Speeder84XL]

The battery loss actually also goes up with the square of the current pulled from it - a given current, gives a certain drop in output voltage, due to the internal resistance of the battery. Now if you double the current draw, that voltage drop will also double. 2 times the voltage drop x 2 times the current = 4 times the power loss. Most of the power loss is probably in the battery (since that's the main limiting factor for most electric cars) and we can actually see how much in the video, by looking at the battery voltage (even if we don't know the current, we know that the power loss is proportional to the voltage drop - the current can be calculated from "battery power" divided by voltage though, but not needed EDIT: I saw after writing this that current is also shown, haha - but same thing still applies) For example during the fast acceleration at 1:20, it drops from about 390 V to 310 at peak current draw (wich is an 80 V drop) - that's 80 / 390 = 0,20512... or about 20,5 % of the power lost as heat in the battery. During the slower "chill mode" acceleration it dropped to 360, so that's just about 7,7 % power loss. It's pretty obvious that the only thing "chill mode" does, is limiting current draw from the battery by limiting available power. Apperently it's better to just have it in "sport mode" all the time and if you want to save power, just don't push the throttle more than like half way. The slow throttle response does nothing to save energy - it just takes away much of the fun by an electric car and gives back the feeling of an ICE car, haha

[@bluetrepidation]

If you double the current you also are decreasing the amount of time it takes to reach speed. So there has to be an acceleration sweet spot. Has anyone calculated this?

[@magnusdagbro8226]

@@bluetrepidation there's no sweet spot, the longer the acceleration the better. Also it helps doubly because you're going slower (with less aero drag) for longer. But at some point you get into diminishing returns so don't go crawling in traffic just to save energy.

[@Speeder84XL]

​@@bluetrepidation The losses go up more than the time to get up to speed goes down, so to say. Accelerate slow also means you will go slow for a longer distance, so your average speed and average air resistance throughout the drive will decrease. Simply, the slower you go, the less energy it takes. But there might be a sweet spot (a compromise) between having fun driving and energy consumption. If you do a really boring slow accelerations, you may get very low energy consumption - but not very much lower compared to if you accelerate like half throttle for example. But if you really floors it every time, the consumption will be significantly higher. So there may be a sweet spot, where you can still have some fun, but keep a reasonably low consumption. Same applies for speed, as air resistance increases with the square of the speed. Athough that's also very situation dependent - depending on driving distances and chargers available. For long trips where you really need range, it will actually be a sweet spot for your "cruising speed", where your total travel time (and average speed for the whole trip) is the lowest. If you go too slow, you will spend so much time for the drive it self, that even if you make less charging stops, it will still take longer (not to mention that if you are like me and don't like to go slow - a 3 hour trip is nicer if it consists of 2:20 driving and a 40 min charge stop, compared to a slow boring 3 hour non stop drive). But if you go too fast, you will run out of juice so often that you will spend too much time charging. I would guess highway cruising speeds of 140-170 km/h (depending on battery size) in low traffic, is pretty much the optimum speed in a Tesla, if there are fast chargers available along the way.

[@thomasbuilder]

So this has confirmed my suspicion: chill mode or eco mode on other cars don't make them use less energy, only they restrict the throttle/performance of the vehicle. If you drive carefully without flooring the pedal they don't change a thing, they only help those who usually tend to use the throttle more radically. I would argue that chill/eco mode is worse for experienced and mindful drivers since they don't lower the consumption but they restrict the cars performance hence it won't be available when it's useful/necessary in a dangerous situation for instance.

[@SirHackaL0t.]

I think chill mode would make a potential difference when accelerating and slowing more than when driving at a steady pace so trips around town doing stop/start driving would benefit from chill mode as it pulls less amps from the battery. I suspect when you yoyo to warm the battery you would see a differencebetween sport and chill modes. Maybe worth a try.

[@Sabeximus]

The point was that if you drive normally or carefully, the mode doesn't matter. It's like putting a brick behind the acceleration pedal: Chill Mode just prevents the max output, but you can drive just the same as if you had Chill Mode on by not pushing the pedal to the metal with Standard Mode.

After a while, you learn how to feather the pedal in standard mode so you don't need to enable chill mode anymore.

[@fredrikeklund9663]

I would like to see you Björn doing a explanational video of ECO-driving, go trough the theory of common settings on EVs and how they would effect the consumption in theory. for example explain to people how different ways of slowing down your car will effect your energy consumption. from best to worst. coasting to slow down by friction and drag ---> light regenerative braking ----> heavy generative breaking ----> frictional breaks. Fun fact: the equation for kinetic energy is E=(m*V^2)/2 m=mass, V=Velicity this means that if you slow down your car with frictional breaks to half your original speed, you have wasted 3/4 of your kinetic energy to heat in your breaks. Please give a thumbs up on this comment if you would like to see Björn making this video.

Even though I like the acceleration of the normal mode better I still prefer using the Chill mode as I am not the only passenger in my Tesla. It just makes it more comfortable for my family. Also, I think as many other people have pointed out the Chill mode would probably make a difference in the city. Bjørn it would be very cool if you could repeat your tests in the city.

[@Laykun9000]

I like using ECO mode on my 2018 Leaf, not because of the promise of saving battery, but because it smooths out sudden accelerator jostles and makes the trip way more enjoyable for passengers (we have some bumpy roads here, which in turn jostles your accelerator foot creating a jumpier ride). When I wanna be first at the lights I turn ECO mode off.

[@marlonwinderaiam0899]

I think you will see a more significant difference if you test in the city. Chill mode is much more efficient when you’re in stop and go traffic. At highway speeds, you won’t see a big difference - especially if you are cruising with auto pilot.

[@peterhelm522]

I drive often in winter short trips of 2-8km with my 2020 M3, because I hardly use the bike than. I use a climate setting o only 16°C and fan speed 1 or 2 and seat heating. I have a jacket on anyway, so that is not problem and a ICE car also would not get warm on 3km. With that setting I use 170Wh/km instead of 230Wh/km. On Long trips of course I heat to 20°C to stay comfortable. During the week I only drive such short trips (also due to the pandemic), so it makes a huge difference in consumption.

[@Sp1nkick]

check out what the manual says about cars with the heat pump: You can improve efficiency of the cabin heating by reducing your selected acceleration mode, allowing the heat pump to take more heat from the battery to efficiently heat the cabin instead of maintaining the battery’s ability to provide peak acceleration performance. ‘Chill’ is the most energy efficient mode, especially in cold weather. To adjust your acceleration mode, tap ‘Controls’ > ‘Pedals & Steering’ > ‘Acceleration’ from the vehicle touchscreen to adjust the amount of acceleration you experience when driving. Select from one of the following modes: ‘Chill’ limits acceleration for a gentle ride and optimizing cabin heating in cold weather. Note: When Chill is selected, Chill displays on the touchscreen above the driving speed. ‘Standard’ provides the normal level of acceleration on non-Performance vehicles. ‘Sport’ provides the normal level of acceleration on Performance vehicles.

[@anttitoivonen7339]

It would be nice to see comparison between heater auto mode and manual with different fan speeds. In winter I mostly use manual in 1-2 speed which seems to reduce the consumption. I think there should be setting for auto mode to prefer lower fan speeds. Higher fan speed = more heated air exits the car and more coming in needs to be heated.

[@theRECONN]

I think Chill Mode is purely when you don't want the jerk to be too high when you are not paying attention to the pedal pressure. However, if you get used to and comfortable with the standard/sport mode, you'll probably get a better consumption.

[@john-bjorn]

To me 22,0 kWh/100km is not a high winter consumption in my eyes, but the future might change that, I don't know. But I usually end up around 30,0 kWh/100km during shorter trips in my Polestar 2. A heavier car and not as good aerodynamics as the Model 3 though so it should be higher. But still, I'm happy when I get around 26,0 kWh/100km now during winter (but then I have to drive longer trips to get that). :) Also done some tests without the heater in the Polestar 2, makes a big difference :P But not so pleaseant xD

It's more efficient to coast to a stop than regen to a stop. By coasting you get a shorter distance/time where you use power maintain speed. But you will not be well liked by the people driving behind you. Just look on the hatred twords Prius drivers. But I doubt it will be enough to notice. I would more see it as a preference of what you like, and not high efficiency is. But personally I would have like to a mode like what the Th¡nk had. When you let go of the accelerator, you would coast, but it used regen to prevent you from increasing speed.

[@MichaelEricMenk]

@@starsundsternchen802 the channel Unplugged EV have already done those tests in his outlander PHEV. But there is no significant difference, because if you drive efficient, you will not regen on max, even if you have it in max regen.

[@richardgoldsmith7278]

A stop start journey would show more difference. Essentially it stops you from using so much when you floor it from every lights stop. Cruising was never going to be different as the energy requirement isn’t different. You can waste energy by accelerating harder or going faster, so it’s about inadvertently wasting energy unnecessarily, and chill mode limits that. I like it because it is less savage on the neck muscles.

It shouldn’t. Model 3 has an induction motor in the front, and at low power demands it only uses the more efficient pM motor in the back.

While you are using the same amount of power, changing the max value is of no effect, and this is basically the difference between chill and sport mode. On the other side, with the D vs B mode discussion, there are some arguments that could mean that D is more efficient than B, but only if the car regenerates when you press the brake pedal. But I don’t think that the differences are too big and they are heavily dependent on the driving circuit. Regarding your foot temp problem, it seems like your car can’t check the temp roof the air going to the feet, so because of the external temps it goes to full heat the whole time, not only while heating up the cabin. I suppose that there is a faulty sensor in the HVAC unit, but not knowing how many sensors Elon has substituted with software models, it’s to say.

[@1sheinz]

I would think the difference in sport and chill WON'T be found on the highway, but in CITY DRIVING. Just like ICE vehicles you get much better millage on the highway compared to city, as your throttle applications are very muted and fewer as speed changes very little, but intown your foot goes to the floor each traffic light and then back to idle every 100 meters. THAT is where you might find some difference. The other thing that will be different is very gradual and may not show for 10 years. You will have much more stress on the Constant Velocity bearings in the drive axels and in motor mounts that will fail years beforehand if driven in sport ALL THE TIME. These CV Joints are designed for ICE vehicles and are rated for less than 400 HP, so using 400 amps from a standing start is somewhere around 750 HP, Causing undue stress. Being a all wheel drive vehicle reduces the strain on each CV by 25% and that is why they don't fail immediatly but long term life is shortened. CHEERS Steve h.

[@bwilson4web]

At a constant speed, there will no difference. To see the energy difference, you need variable speed. For example, use the power poles next to a road and do a maximum acceleration to the next and then deceleration to a stop to the next. What happens is the (I**2)R losses of standard mode will lose more energy than using CHILL with the same protocol. At a constant speed, there will no difference.

Actually D is more efficient than B. The reason is you drive a litte different, let off the throttle earlier in D, while in B you'll be more likely to "brake late". Steady speed gives the best efficiency.. But ECO makes no difference other than a sluggish throttle-respons.

[@bjornnyland]

Nope

[@therandomtester9561]

@@bjornnyland nope what? Proof? If your tests show different, there must be something about drivingstyle.

It could be great to make a sport mode protected by a PIN. If you lend your very fast car to inexperienced driver - it would be much much safer for him.

[@bjornnyland]

Use valet mode

[@adewouters]

There is no point to check the difference between Sport and Chill modes when driving +/- constant speed on the highway. The difference is only in the accelerations. So, a better test would be something like make 10 times a 0-100 km/h acceleration flooring the accelerator in each mode (if that's enough to have a sufficiently meaningful value), and see what's the difference then. I believe, you will see a much bigger difference.

[@bjornnyland]

My point exactly. Can people now stop nagging me about using D mode instead of B mode?

[@adewouters]

I'm glad it's your point :) Ignore those guys, you drive how you want...

[@TheGomezIndustries]

Best way to increase efficiency is to minimize weight as much as possible.

[@jdnrotterdam2150]

I have Flitsmeister on my phone. That a navigation app with radar alarm. If i drive 105 KmH on my car meter. Than the navigation app gives 95 KmH. What is correct? Or is it in the middle?

[@e-redj]

The Speedo of your car has by law to show a higher speed than you are really driving at. Björn has many times shown that at Tesla is only about 3kph. But the speed of your Speedo is highly dependent on the wheels you use and if you can give the car any correction factors for smaller or bigger wheels. The car only measures the rotational speed of the wheels. Regarding your app, it uses the GPS sensors of your phone. When you drive at constant speed it should be your real speed, but they are quite slow to detect speed changes. But 10kph difference, it sounds like a Toyota, they over exaggerate speed by a lot.

[@jdnrotterdam2150]

Yes it’s a 2012 Toyota prius. The business edition with the bigger star wheels.

[@jdnrotterdam2150]

In holland the speed limit is 100kph. So even on longer roads with cruisecontrol at 105 kph all the time the iphone gives 95 kph. But if i drive 55 kph on my speedo in the city than The iphone gives 49 kph. I always drive 5 km faster than the speedlimit op my speedometer because i think the real speed is in the middle

[@e-redj]

@@jdnrotterdam2150 while some companies like Tesla simply add 3kph to the velocity it gets from the sensors, other like Toyota add some kind of proportional factor, so the faster you go the higher the difference. I would trust the iPhone.

[@jdnrotterdam2150]

Yeah maybe this year a new electric car for us. The prius already have 190.000 km on it.. so time to make the step from hybrid to electric

[@gorbi13G]

in 2014 eGolf B mode is more efficient than D mode - it enables a little bit more powerful recuperation - so yes, there is B mode more efficient than D mode .. but in other cars can be situation different.. Can you Bjorn test please 77kW ID.3 and ID.4 or Skoda Enyaq ? :-)

[@davidsommen1324]

Only if you decelerate a lot B mode might be more efficient - with highway driving coasting is generally more efficient than regen

[@harsimranbansal5355]

@@davidsommen1324 yea, when you regen it has to convert kinetic energy to electrical energy, and then convert AC into DC, but when you accelerate again you have to convert DC back into AC. I think total system efficiency is about 70-80%. Coasting is basically 100% efficient since you’re not using any energy to move and you’ll slow down just with friction alone.

[@bassbacke]

Why should there be a difference in consumption at a constant speed?

[@bjornnyland]

My point exactly.

[@bassbacke]

@@starsundsternchen802 I very much doubt that any downhill/uphill on that 8 km strech required more then 150 kW. Regeneration with chill mode is the same, if gravity is high enough one can both keep a speed and regen. Chill mode is not coasting. Why would you bring that up? Context matters.

[@jean-paulvandeheijning5088]

It might be more economical on the tyres :-P

[@noocyte]

Yes, but again like Bjørn says; you do not have to use all 400 KW in Sport mode, you can just use the 166 KW that Chill mode gives you... ;) I used Chill mode the first 4-5 weeks with my TM3, just to get used to it and get a feel for the car. Now I have it in Sport mode. Loving it.

[@bjornnyland]

If you are clumsy with your throttle, yes.

[@sithsiri]

For some drivers (especially younger or much older drivers) the reduced throttle sensitivity might be safer

[@deraussendienstler]

how do you set up a car without air conditioning? that doesn't work with my august 2020 model 3. every time I go to Auto the air conditioning comes on.

[@blackmoon925]

Just disable "Auto" and after that "A/C". If you insist on "Auto", you can't control "A/C". But I think that's the case with most modern cars.

@@deraussendienstler I know, but there are worse annoyances in the programming than this one. I don't get, why you can't use the App Climate Control below 20 %, for example. That's a ridiculously high value for a Tesla battery.

[@deraussendienstler]

@@blackmoon925 this is true

[@harsimranbansal5355]

@@blackmoon925 the reason is because when you heat up the car through the app, it also heats up the battery, pulling a total of 11 kw. At 20% your battery would nearly be empty in less than 2 hours. That’s why you should always plug in at night when you want to preheat the car in the morning so it’ll pull from the grid instead of the battery!

[@neilvanmaanen1820]

It would be great if you could compare B and D mode in the ID.3. D mode should be more efficient. www.volkswagen-newsroom.com/en/press-releases/brake-or-coast-the-id4s-intelligent-energy-recuperation-concept-6658 Coasting is 100% efficient, no energy is used. Regen is not 100% efficient due to inverter and charging heat losses. The important thing in either mode, is not to use the friction brakes. D mode will require more anticipation, but I guarantee that it will be more efficient. I believe the ideal is to have various regen levels available as with the steering wheel paddles in the Audi e-tron. Apparently Porsche believe coasting is far more efficient in the Taycan. Obviously B mode will have to be used on steep down hill sections to prevent the need for friction braking. The ID.3 also has intelligent regeneration in D mode (Eco Assistance). It uses the adaptive cruise control radar to engage regeneration automatically when approaching slower vehicles. The ID.3 can also automatically engage regeneration using speed limit and navigation data.

hi, but chill mode is ok in city center! not at constant speed. when you are at constant speed it's impossibile that there will be difference. but if you make many acceleration it's normal that you wil have difference results! bye

You switch acceleration but you test steady driving. That's not a valid test from my perspective. Go 0-200 and see what it consumes for example.
