For me it's very simple, use D always for higways and engage in B when you need to slow down like getting out of the highway or a sudden stop ahead, same way you will downshift a manual car. This way is more comfortable to drive without pressing your foot to the throttle all the time. In the City use B to handle the traffic stop/go the same way you will do with a manual engaged in a lower gear. Don't forget the energy you get back slowing down with B will always be less than the energy you will consume to get back to your original speed so try to cruise more and brake only when neccesary.

Same here but I use b mode when I know i am going to go down a hill as well, instead if applying the brakes.

I have always been a bit of a hyper miler, so when I got my leaf I had to try different things out. By far and away the most economic function is, hold the knob over to where N is for a few second and it slaps it in neutral until you knock it down into D again. When I spend most of my time doing this, the Miles pre KW shoots right up. I use B mode when I need to break a lot, and e-peddle is for when I am in stop start situations so for me it is pretty much used like a handbreak. To be honest I sort of treat it all like a weird gear system. Ironically, as a hyper miler, I have actually started to drive the leaf faster than I used to drive my diesels on long trips.

Very interesting topic, I think the point is to use the mode you fill more comfortable and confident while driving. No big differences wrt efficiency. Thank you for the video

Been driving a Leaf for 6 years and use D most of the time. Only use B mode when needing to slow down. Hardly any wear on the original brake pads and averaged 5.5 miles/KWh over the lifetime of the car so convinced D mode is the most economical.

Great video! Test it don’t listen to random claims ! Thank for the test!

Been driving a 40kwh leaf for almost 3 years.. I prefer B eco over D as I can easily control the regenerative break and acceleration. In first month I used the e-pedal until I notice that sometimes in certain situations the car would just stop regenerating and start using the friction breaks... In b mode I control everything... For me is the mode that suits me more... I can also coast in b mode by moduling the accelerator pedal just right ;)

Thanx Bjorn. Love your vids! I drove D mode for 5 minuts when I just had my Leaf. It was enough to know that i'm a B-mode man! Drives more like a tesla model s (our second car).

Thanks for settling this argument. 😊😊 I always drive in B mode and with one peddle driving enabled driving in my 40kW Leaf. I get an average 4.4 miles per kWh

Please take the Leaf to Northcape. Would be an awesome road trip :)

I have settled on B mode as my mode in most of my driving. I like the control and brake assist and the regen and the less stress on brakes. D mode for Highway. B mode feels similar to a Chevy Spark in L mode with SPORT MODE on. Great way to drive!

Thanks dude!

I'm using B-Mode in the city and D-Mode on the highway. It's obvious that they both are identical in situations where you just drive without some recuperation. But for me it's also clear that D-Mode "can" be more efficient because it's more efficient to use the kinetic energy for driving since recuperation always comes with a loss of energy aswell.

Uh, ok.

Nice video and perfect explanation. D and B is only a difference in how the inputs work. The efficiency of using only little or a lot of regen is the same in both cases, only how a little or a lot of regen is requested by the pedals is different. In B mode the accelerator pedal has to be pushed a little more to get the same result, the brake pedal a little less and the "default" behavior when pushing neither pedal is shifted. But just by slightly modifying how you use your foot you can get the same profile of acceleration/deceleration and consequently the exact same efficiency in either mode. It is just about what feels more comfortable/convenient in the current situation. I like B for highway driving, because I don't need to change to the brake pedal if i need to reduce speed. Also I like D mode for the city because it often makes sense to coast with only a slight deceleration. May be completely different for others.

appreciate the thoroughness of your testing. would be good to try the same test in town (with more braking/stopping) with caveats about the variability of traffic but to see how much difference these two modes have in an urban environment .

Scientific? Irony? The repeated test was only in B-mode as far as I could see. And D was with cruise control on! Waste of time.

I driver aprox 120km to and back from work. For me its D-mode that has proven to be best for me.. alot of 70km/h and 100km/h road. It require a little more footwork and planning but i seldom use ACC if I'm alone on the road.

The most efficient is mixing the two. Under some conditions D-mode is more efficient but in others B-mode is. I constantly switch between the two.

The way the B-mode works may be different for other cars. For Toyota, B-mode is "engine braking", not "extra regenerative braking". In hybrids, this couples the combustion engine to dissipate energy by friction; this is necessary because batteries might not have sufficient capacity for long braking (long, steep downhill), and the electric motor-generators might not have sufficient power for strong braking. Pure electric vehicles have much more battery capacity and stronger motor/generators. For Nissan Leaf, the manual states "B mode engages the regenerative braking system more aggressively on downhill slopes, and helps reduce brake use" (describing shift positions), and "more regenerative brake is applied than in the D (Drive) position" (describing the Braking System). It also says "To help reduce brake wear, and to prevent the brakes from overheating, reduce speed and select B mode before going down a slope or long grade", which essentially tells me that the system was not properly designed/calibrated; why in the world would friction brakes be engaged if regenerative braking capacity is still available? The only difference can be seen going on a fairly steep downhill; going down in D-mode (using brake pedal), then in B-mode, and noting the increase in battery capacity. Driving at a more or less constant speed on highway does not engage any kind of braking, so no efficiency difference is expected. Braking to a standstill from highway speed will simply be drowned in the overall energy consumption.

On a highway stretch you wouldn't expect to break much anyway, so no effect of D/B. In general, to maximise range, the best thing is to keep your speed as constant as possible. All breaking and re-accelerating will cost energy, no matter if you use D or B.

I saw another video someone tested that and they found that only using the b-mode is more efficient than using both the eco mode and the b-mode at the same time was less efficient.

i use epedal for everything

How about stability in slippery conditions, does B or D make any difference? I like coasting mainly because it feels like it reduces the risk of something unexpected happening when the conditions are bad.

I tested this for about 15 years ago.Drive the car the same distance,50 km, with regen and without regen. Find out that the car used less energy without regen.This was for me a surprise, but one must understand that as soon as you use regen the speed decrease and then you have to get more energy to keep up the speed afterwards.The best way to go with low energy is to roll without using brakes or regen.Regen is usefull in towns or going down hills where you have to decrease the speed for safety.Now a days I never use regen.

I drive my 2014 Kia Soul in B mode all the time. I like the one pedal driving and can still coast by adjusting how much I depress the accelerater. I also think the brakes are quite poor and in an emergency hope that regen and friction brakes together would stop me sooner?

B is for Bjorn. So nice of Nissan to add a mode especially for you

Exactly

brake pedal regen is the best like VW e-up and golf....coasting and regen with the brake pedal,you can also do this with the gear stick on a tesla, just pul it in N and you can feel how the car is free coasting...pul in D and regen kicks in :)

I‘m a big fan of one paddle driving. To my opinion it‘s more convenient as you don’t have to switch so often between acceleration paddle and break. If you handle it well, there shouldn’t be a difference between B and D mode. In B you should avoid to fully release the paddle if not needed. This might be the main reason, why people may see a difference between the two modes.

I completely agree on this. The claims about less eficiency on B mode may come from Toyota hybrids, that also have those modes. In those cars, the B mode usually increases the engine brake. Since any fraction of engine brake is not regenerative braking, that energy is lost. This could be useful in a hybrid in specific situations such as driving on a long downhill, where your battery would be easily filled and friction brakes would be abused as the only way to control speed. However, it's indeed unefficient.

If you manage the accelerator very accurately in B-mode, you can avoid the excessive braking that would reduce range. But I think constantly applying pressure to the accelerator makes my right foot cramp. That's why I really really miss having D-mode on my Tesla.

It depends on the driving style of the driver. If you are an on/off type of driver, B mode will consume more. If you keep a smooth flow/speed it wont matter as the regen will anyway be moderate regardless of mode. But try cruise control versus no cruise control. If you allow minor over and under speeds without cruise control it will be more efficient (surfing the hills).

Bjorn! I'm choosing between ioniq and leaf, is ioniq really that much more efficient? If leaf can do 150miles can ioniq do 200? You haven't done 90 and 120kmh range test on 38kwh ioniq.

B / D only applies when you drive without ACC. ACC will always use the full regen and even the breaks on the front wheels to never pass the speed limit or hit a car. Standard CC (long press the button) it will use the regen of the gear such that in downhill in D the speed will get higher than the set speed as with 2010-2017 while B will have sufficient regen for everything.

Bjorn how about a B/D mode test in the city?

@lukasdolezal8245

If the leaf engage regen on braking pedal before it engages friction brakes, I would guess it will be mostly no difference anyway. So it's more just matter of preference - do you like more regen when foot off accelerator B mode, do you like to push brake pedal D mode

D- or B-mode is just a convenience thing. A matter of taste like he said. How much regen are you comfortable with when not using the accelerator. In long stretches of downhill i prefer B sometimes to rest my right foot. Most of the time I'm just using D. In cruse control with constant speed, it doesn't matter at all since the amount of regen depends on the terrain, not on D or B.

To my tastes, a "go faster" pedal and a "go slower" pedal arrangement makes sense, with no regen when both are released, but with an option like B mode for descending hills (perhaps with a more extreme mode for steep hills, like the S and L positions on many Japanese automatic transmissions). I suspect that with one-pedal driving I'd always be trying to find the right spot, but then we manage that when driving an ICE car without cruise control, so maybe I'd get used to it.

💯

The challenge with mixed pedal is: you have little to no idea if you engage the friction brakes or not. If you are in D-mode you have to use brake pedal to rappidly reduce speed, you can easily push a little too much, and wast energy on friction brakes. If you are in B mode, you can just push the accelerator to use less regen, like coasting, and avoid friction brakes unless you have to.

B mode makes it more likely to do unwanted regen and less likely to use the friction brakes. It does mather but its much more about the behavior of the driver. I actuely use neutral to coast and enable D D+eco and B when required. And always use B mode at low speed city driving to avoid the brakes Highway driving on cruise control makes no difference of coarse if you are in d or b

Wunderbar. Next time compare N and R mode 🤣

Hi Bjørn when would you test MG 5 one of the cheapest ev on market. All the best 👍

It depends how you drive. On the Ioniq EV, you can have zero regen. This allows to anticipate more and freewheel. You can then regen only when needed. If you setup the car to use regen as soon as you lift the foot from the pedal, it is more difficult to freewheel. This allows to stop using energy earlier and slowly decrease the speed (anticipating a sharp turn or some traffic ahead for example) instead of continuing accelerating for more time and then using regen at the last minute).

They probably thought that R for Regen would cause more issues.

I use B mode all the time instead E-Pedal for simple fact that brake calipers does not apply while braking and first of all less ware on brakes, less dust on lovely alloy rims. On motorways B mode does not make much of difference in terms of energy recovery but if you on the mixed traffic area, town bypass etc it gets more energy back to battery. E-Pedal on the other hand is absolutley perfect for City drive. My best case scenario on B mode is 25% energy recovery on mixed drive and no brake dust on rims :-) One thing than need to be taken to account on B mode brake lights does not apply so driver behind might not be aware you are slowing down more aggressively. E-Pedal then apply brake lights to early in my opinion annoying drivers behind and use brake calipers to soon losing maybe 6-10% more recovery energy plus dust on rims. I know i said dust on rims 3 or 4 times, I love clean rims :-)

Also noticed, the avg speed for first B mode was 84. The other 3 were 81. That might explain the small difference in consumption as well.

It probably doesn't make difference on cruise control :). If driven by foot - efficiency: D > B > ePedal. Unless you have a good foot to control the regen, otherwise even slightest movement of foot can affect the efficiency.

I bet people with only three or four right foot accelerator positions will greatly reduce consumption in D-mode. All Taxi drivers I used lately have this "problem", they cannot pulse width modulate their feet for a smooth drive.

During the last 24 hours, we've change to D and B, coasting to stops such as junctions, lights etc. We've used B in a similar way to changing down in a manual car, bringing the car to almost stopped without brakes and our efficiency has gone up to 5. We also live in an area where there are many ups and downs between our house and the city centre. We are seeing 5.5. on the way to town and 5 on return. It's just a matter of getting used to driving gently.

Regen is more important at slow speeds and stop and go like in a city. D is better for highways and B is better for local traffic is what I would expect.

Like he says in the video, you can apply more regen by slightly pressing brake. This enables less aggressively slowing down and not wasting energy to speed back up if situation actually didnt need so much braking. B mode due to releasing later, can make you apply brake pads because you had less time to assess situation. D mode = Defensive mode and better economy - you release earlier and are ready to brake if necessary. B mode = Berserker mode and less economy - you are more likely to drive too close to others and you are playing with acceleration pedal to adjust things - less safe.

Tror testen av B mode mot D mode hadde vært mere interresant om du kjørte uten cruise kontroll på normal svingete landevei.

That's not the point.

Given these are electric motors, shouldn't there be an AC mode? This would clearly be better....... whatever mode you use, we all can be certain of Tesla Bjorn for the win!

Regarding brake blending and maybe a test for some videos. I have seen a test where they showed to ice users what regen actually means by measuring the brake temperature after a steep hill for an e-tron and another combustion car. Since the e-tron had a break temperature of 90C (ice 199C) and not ambient temperature i thought it would be a nice test to see if all those claims about break/regen blending is not just appling more regen + normal brakes at every break modulation. One could for instance drive down a hill with constant speed and measure break temp at the end in different scenarios, without regen (N) and use only break as a reference, then drive down with only regen (no break) and then with regen enabled + break blending but pressing the break only that much where the car shows that only regen is being applied. This will show how good break blending works and if it is only marketing scam hiding small regen.

On most modern EVs brakes are intermittently applied lightly to keep them clean and dry, and also when you start pressing the brake pedal in preparation for applying more braking force. There is also a limit to how much regen power can be absorbed, especially if the battery SoC is high, so if it was a very steep hill this may be a factor. Some cars also use brakes for torque vectoring. Brake blending is no scam, in many cars you can feel the transition from regen to brakes, or you can see the regen power with a OBD2 reader as Bjørn has shown many times.

@@nordlands8798 Cleaning the breakpads will have zero effect on the temperature of the break on a single test. Appling brake force via brake and how much when you hit the breakpedal is exactly what this test will show. Using high SoC would be dump in such a test and can be ruled out by the test setting. Torque vectoring applies when you accelerate not decelarte and even if you insist, just use a straight road for the test. Maybe i explained myself wrong, break blending is a thing but that you have zero brake usage until the car maxes out in the display for regen power, that is the test subject. Brute force you could also just disconnect the brakes and see how much regen the car really has but this cannot be done. It so often said that a car xy uses more regen when you press the brake and no brake will be applied. This test will show if that is true. Most of the cars that have this setup do not have a simple option to just enable full regen on the gas pedal and this test will show why.
