- High speeds and low temperatures are an EV's worst enemy when it comes to diminishing range. Alex Kersten borrowed Rory's Nissan Leaf to to find out how quickly he could run the battery flat, by driving at top speed, in sub-zero temperatures. In the name of science, of course.

Here's how far the Leaf goes if you drive gently! th-cam.com/video/NwTuk1kxc20/w-d-xo.html
hi
Rory and Alex are superb together, this was great
Definitely better than the token woman

Finally, the diversity trinity is complete
Nah they shouldn't include this guy
There is only eight battery bars they’re supposed to be 12 you’re not gonna get that much range
This was brilliant.
I am actually surprised how far the Leaf got with a shagged battery.
In cold weather too , that makes a huge difference in EVs !
isn't the 8 bars equate to 80% efficiency left, wouldn't call that 'shagged'
@@caolkyle I would if its original real world range was only 80 miles and that was with good batteries
@@BillyNoMates1974 I think going over 20miles driving like that was actually really good. Given to get most out an EV would be city driving anyway. To get 60/80 miles is good and really cheap if it’s purely a commuter car or getting shopping.
Then have a ice or longer range electric for longer trips
@@caolkyle it 8 bara out of 12, so more like 66% left
That poor confused BMS. I'd have loved to see a Leafspy readout during this to see what it was thinking.
I was thinking this as well - I'd bet if anything you'd find a few bad cells pulling the whole pack down, but this was still a pretty impressive showing all-in-all
It was thinking oh boy I got plenty of range, I coul..... Oh no, OW! Where did my cells all go?!
Take out as many as possible on this same test. It would be amazing to see how they perform on top speed. My Kona 64 drops quite a bit, but obviously I can't range test at top speed on motorway. :D
Agreed!

My MG5 cruised at 70 in -4°c a few weeks ago and did about 178 miles which was far more than I expected of its 250 mile good range!
@@FalloutNewNarwhal 70 isn't top speed, is it? :)
That's a great video!
I'm studying electrical engineering and nothing came as a surprise in this video! You can see the battery temp's quick rise, the premature turtle mode, the gentle degradation of power, and the cutoff at the end. Li-Ion battery characteristic in reverse :D
Great to see theory in action!
It’s not a Li-ion battery.
@@gobinduppal4429 The warranty booklet literally calls it a Lithium Ion battery.
@@htimsrecneps hmm. I thought the early cars were Ni-Mg
@@gobinduppal4429 Early EVs often were the likes of NiMH. But by the time we got to the first LEAF it was always Li-ion. The exact chemistry was revised a lot over the years to improve reliability, efficiency and longevity of the battery health. But all of the LEAFs were based upon Li-ion technology.
The LEAFs use NMC chemistry
The BMS was probably like 'You're drawing how many amps from a 10 year old Nissan Leaf battery? For 10 minutes??!! Okay I''m out."
Skoda in the back just chillin while the leafs working over its ability
Love this kind of content!! Great to see Alex and Rory together on Autotrader! This is fantastic.
BOT
@TheClayZay i can confirm that I am real 🤣 well i think i am anyways 🤔
I would've liked to have seen the GPS speed. The Speedo on my Leaf shows 87km/h when my GPS reads 80. 97mph, somehow I reckon you were going pretty close to 89 .......
Absolute hoot of a video, thanks for sharing, got a good laugh 🤣
Yup. My leaf needs to show 80mph on the speedo for real world 70mph. They're notoriously inaccurate! 😁
@@W2APS Have you changed the wheels to a different size from the original specification? Any 24 or 30kWh LEAF Should always be an indicated 77mph to do 70 real world if on original wheels. They are set to over-read by exactly 10% in the name of efficiency.
For sure they were going exactly the 89 IRL just as quoted. Its a software limiter after all.
Cars in the UK come with a tolerance of up to 10% over, but they cannot be under. My car is 2-3mph off at 70, my girlfriends is 5-8mph off at 70.
Now that's a test I can get behind.
Great video, great chemistry with Rory and Alex, and I almost cried when he pulled out mince pies as a snack!
(I'm from the US, but my Nan made amazing mince pies).
now thats a perfect example of ''good content''
Really? Well you're easily pleased then.
@@captricharddee3634 be toxic somewhere else.
@@captricharddee3634 I bet you prefer drag races
Excellent, Alex and Rory answering question we didn't know needed answering... surprising that it lasted as long as it did..
Hands down the most entertaining EV test video of the year!
I love this first test, I drive an older Leaf..and I dont use it for speed...but this is amazing! The Leaf is an amazing daily driver
The Leaf is such an underrated car. It's not meant for everyone but for those in the target demographic is perfect!!!
For the record I think there's a manual release for the e-brake in the boot/trunk underneath the false floor.
Don't you need electricity to open the trunk?
@@pogo1140 Yes but like a combustion powered car there's a 12V battery under the bonnet that's separate to the traction battery. You can drain the latter but still have power to operate the lights, doors, windows, etc.
@FengWah and the handbrake solenoid can't be released by the 12v battery?
@@pogo1140 Apparently! Fortunately I've never had the need to find out first hand.
@@pogo1140 Should be possible, but I think they drained both batteries. A jumper pack could probably solved the issue. Also, if they had stopped just before the car went into neutral, they could recharge the car by towing it and use regenerative braking. Have personally been towed for about 40 miles, got 95% charge
you know what mate, this should totally be a full on series! driving cars flat out untill it stops completely in the autobahn
Absolutely brilliant for bringing Alex on the channel! Good job auto trader 😂👍
I love this channel so much. Incredibly fun!
Should do this in all aged EV's, sooo entertaining!!!
Leaf's are fairly unique having no temperature regulation which predictably ruins the battery.
I think it calculates a conservative range based on speed/battery draw but also sheds load to prioritize driving continuously even at lower speed. Pretty impressive really. Took a weird turn with feeding him but it was a good ride. Nice video.
I have 2014 Nissan Leaf, LOVE IT!! 77,311 miles with 10 capacity bars!! I get 67 miles on a full charge.
These guys are officially the next top gear. Top notch content, extremely entertaining
Very creative
Would like to see the same test done on a Tesla Model 3 long range... Just to see what you actually get
One from the first production year
Might be not much more actually, becuase of the Teslas much higher speed limiter increasing power draw almost exponentially.
Tesla just got fined in Korea for exaggerating claimed range
@@GoldenCroc Most people with EV's tell me to expect 40% of the claimed range if you drive at highway speeds (80 mph) in these temperatures. So maybe 80 miles on the Tesla in the real world?
EV's are for city folk.
@@michaelp4122 I am not sure we are talking about the same thing here... are you talking about the possible range of the tesla at 80mph? Because the same test as this "car range at top speed" is way, way more than 80mph for a tesla model 3, and consequently the range is much lower than at 80mph, thats why I wrote the post above of the range not being much more than this leaf, at each cars top speed.
I like this. More more!
Would be interesting to see a comparison with 3rd generation Leaf with the bigger 🔋fitted.
More of this please, absolutely brilliant. 🙌
This is a 8 bar Leaf, so it has a lot of battery degradation, but even I was impressed it was about to travel that far at that speed. At least you had fun in the test. That smell was probably the gear oil as it has an pressure exhaust for when it heats up and since it probably doesn't ever happen unless you drive at full power for a long time, nothing to really worry about. 😁
21.8 miles (33km) is considered far? I drive around 80mph (125km/h) on the highway all the time, at temperatures colder than -3C....
@@michaelp4122 Considering the math, yes. Show me any full sized passenger vehicle that can drive at +90 MPH on a half-gallon of gasoline (same as a fully charge 8 bar Leaf) for +22 miles and that would be the world record for gas vehicle efficiency. 😄
@@AmaranthineTech Why half a gallon of fuel? Compare full tank to full charge. That's the point, a fully charged Leaf is useless in the real world.
Also don't thumb yourself up......
@@michaelp4122 Because videos that try to compare EV to Gas range are not comparing apples to apples. A full tank of gas to a full charge means nothing. If you want to compare, you do it right. Compare actual energy to energy. Otherwise, the comparison is useless and means nothing. Anyone can add more batteries to an EV or add another gas tank to increase range. I always laugh when I see videos that complain about EV range, like somehow the gas vehicle could even approach the same efficiency of an EV is a silly thing to try and prove in a video. 🤣
@@AmaranthineTech If I drive out of town, I want to know how far I can go. If the leaf gets me 22 miles and my cottage is 220 miles away.....well I don't even make it to the on route charging station LOL
So yea, it only makes sense to compare full charge to full tank when referring to range. The reason why a lot of people don't buy ICE is because of range anxiety.
Who adds another gas tank to their car? This isn't a Safari in Africa. I'm also pretty sure modifications like these void your warrenty.
You have a weird perspective
They're brilliant together, what an unexpected surprise
Interesting excercise. I had expected it to do more. I had a Rex EV fir 4 years and never had any extreme loss of range, however I did always drive normally with flat out only for short periods.
My Nissan Leaf (2012) with new batteries salutes you. Well done, so much joy. Now I wish I had access to a track.
Title should have been, "How Far Will a Leaf Go, Driven by a BMW Driver."
Rolling resistance stays roughly constant so the power to overcome it is directly proportional to the speed. Air resistance is very different and increases as the square of the speed. The power to overcome air resistance thus increases as the cube of the speed. As an example , suppose at 30mph it takes 3hp to overcome rolling resistance and 3hp to overcome air resistance so a total of 6hp . Now accelerate to 90mph , the power to overcome rolling resistance is now increased by a factor of 3 ie 9hp. the power to overcome air resistance has to increase by a factor of 3 cubed i.e. a whopping 27 times , so the horsepower is now 81 hp . So the total horsepower has gone from 6hp at 30mph to 90 hp at 90mph. No wonder the range was so diminished.
Great video! More crazy tests on Leaf please?
great video 🌹
I own one, 2013 model
It's a beautiful car
I bought it in 2022 for $10,850
It really is an amazing car
On a cold day too, gotta love the snow on the ground
Such a fun review - THANKS
How about a model 3? Do the same test!
Rory and Alex ,wow what a team,more of this please
I've been tempted in the past to buy one of these with them being as cheap as they are, but I was always hesitant about their range. My current work place is a 50 mile total commute through surface streets where speed limits are 45-55 mph. But if that changes, I may end up having to do interstate driving
Yes yes yes, this is a strong duo. I was excited to watch and am impressed with the video.
First video I've seen with Alex since he left CT. I missed him from there as his and the teams banter saw me through many a furlough! But now.. the powerhouse that is Alex and Rory 🥳
You can keep up with Alex weekly on his new TH-cam channel: Autoalex Cars
Excellent video guys.
Excellent Test!!
Do more like thisssss!!!🔥🔥🔥
Great video! Thanks for sharing!
You gotta love this duo
Brilliant love the speed impressive cheers lads.
3:09-3:11 look at the left side of the screen at the top railing of the track the guard rails they are giving the illusion of them going backwards through the windows on the drivers side lol its a visual mind trip!! And when you look at it again look on rorys side it's normal...haha
we are a nissan dealer, our old hack does up to 103mph for about 25 miles, 4 up, heater on medium. the biege interior is now a dark leather type of finish
try reading the owners manual, the handbrake release is under the boot floor, but it only reqs a 12 jump-start, you flattened the normal 12v battery cocking about at the end, doh...
Excellent video Doing the same test on a hot day would be an interesting comparison .
Note if air-conditioning used in the summer it works the same as heater draining in winter youll lose 10- 15 miles straight away
The A/C pulls less than heater on ;)
@@jorgetomas3983 i drive a Nissan leaf and i found it roughly the exact same . ill retest it again this summer . The only difference i find is winter heater on lights on windscreen wipers + rear window heater on so bound to pull much more in winter off the total miles than summer .
ill try and do better test winter during day with no lights no windscreen wiper + no rear heater . just heater against A/C summer
@Bob G you know that everything that is connected to the 12V battery doesn't affect the performance of the HV battery? The only system that affect the HV battery is heater or A/C because these systems are connected directly to the battery. I understand that you have consumption but its very little compared with those. I have a Hyundai Kona without heat pump. I saw it once consuming, at full power, 6kW while heating but the average is like 2kW. In summer, the A/C pulls on average 0.7kW
Need more tests like this .
Still waiting for the Nissan Leaf UPGRADES..... Come on Rory!
Is Alex part of AutoTrader now?!? That’s awesome!
An entertaining range test. It's cool how much utility these old LEAFs still have.
You CAN tow the LEAF . You just need to get all four wheels off the ground
If they power up you can tow in drive the car just thinks it is going down hill it will regen if you lightly brake and your range will go up.
If you 'jump start' the 12 volt battery you can release the parking brake. The only time my 2011 LEAF failed on a run was when the 12 volt battery went dead. After a 10 minute wait it did what most Lead/Acid batteries do and regained enough charge to operate the controls.
My 2013 LEAF has a foot operated parking brake where you would normally find the clutch on a geared car, so I suspect that the electric handbrake on the original car was not a great design and was dropped.
@@mattsmith517 My 2014 LEAF had the foot operated parking brake, My 2018 2.0 LEAF had an electronic parking brake, my 2022 LEAF Acenta has the foot operated brake, whilst the Tekna has the electronic brake.
I believe its a matter of price. (profit margins) BUT-
My sons MG4 has an electronic parking brake even though it is much cheaper than the LEAF.
@@solentbum Yuck. I hate electronic parking brakes. Another reason to stick with what I have.
lots of fun. Surprised it managed what it did. Would be good to take a few cars or one modern one at different speeds to see how it affects m/kwh. 100mph not that useful (but fun), but seeing the ‘fuel efficiency’ at 60/65/70/75 could be useful for people?
Rory and Alex, absolutely fantastic in this video. Great video 👏
I think I'm right in saying that this is an early leaf (grey interior - made in Japan) so has the non lizard battery and they resistive heater rather than a heat pump. I got up to 99 in mine on a closed road ;) and it was so safe.
When I took my Polestar out at the Corvette Museum I think I used something like 3x the normal power per mile? It was intense!
So damn good to see you guys ! Happy holidays🌲Only the other Alex is missin, my middle name is also Alex, too many damn Alex's😂
Happy to see Alex on here!!
Would like to see you guys upgrading the Leaf's battery for one with the double capacity and reporting on the advantages. Search for a company called Cleevely Electric Vehicles, they are based in Cheltenham and the service only takes a couple of hours. Surely you guys can get a discounted battery for some 'free advertising'.
They have stopped battery upgrades , to many issues with them , they will still do cell replacements though .
Cleeveley's did a full battery refurbishment on a 9 year old Nissan Leaf a few years back. The job took 4 hours, and the cost was £500. They posted a video of the refurb on TH-cam.......
I would first ask them to check LeafSpy for bad cells. One bad cell can bring the performance of the whole pack down, and you can take it out and replace the bad cell with the correct High Voltage working procedures. Clevely have done this procedure in the past.
Leaf is for the junkyard
There is a company in the US called Ample that's replacing Leaf's battery for one with their modular design, check on TH-cam for a report from CNBC
Great video :) 😊😊😊
Great video thanks.
Wondering if doing this test, degraded the battery at all?" or will it still do 66 miles if driven lightly? . (or was leaf spy health reduced)
My 2017 40kw leaf is at 92.5% health currently, had it's charge level down to 4% for the first time yesterday(it asked about charging stations at 5%), and was wondering what happens when you run out. And also wondered if doing it effects health by much, or at all.
Crickey, is there a way to turn off electronic handbrake? other than charging the car a bit.
Nope , there is no manual override. Car will need to be charged to release it. Kinda silly that it can’t be done without the motor “on”
@@DeafeningSounds Sure is a stupid arrangement, guess if it happens i will fire up the 2.1kw(1.7) electric start Dometic genny i just bought, which is going to live in the boot. Weighs 26kg plus fuel, so a bit of a pain, and slow charging at 6 amp setting, but better than being totally stuck.
I do have a 12v 325ah lifepo4 battery, so debated using a 2kw inverter and it instead, but the brand new Genny was $1/3 normal retail price, so grabbed it.
Probably woke the cells Up a bit 😁
great video guys
I actually like this duo! Nice Job Alex
As a driver of an electric forklift truck, surprisingly, using the horn does use a huge amount of energy
Rory and Alex! I NEED more! Awesome!
Make this a series!
That was great. Highly enjoyed it. I'd love to see it in a bigger battery car, something like a Tesla or even a Bolt.
It does only do 89mph. The Leaf is notorious for overreading by 10%. Also the 12 battery capacity bars are not linear at the top end. You don't lose the first one until the battery is down to 85% state of health (SOH). Thereafter you lose anothe bar for each 7 - 8% of capacity lost. With 4 bars missing this Leaf has lost around 40% of its capacity.
I have seen this in Kenya my frist time in the airport last 2021 and still see them
I really drive this car :D...
I have a 43.2kwh BEV. Its recommended speed is 60kph, and can do a 360km range with it. But when I cruise at 100kph, it need 20kwh/100km to maintain the speed. Also AC and any incline will affect the range.
Also you never want to use the last bit of power out of the battery. So another 30% of battery is "useless". Leave that 30% of battery for what if your planned EV charging station closed.
Great test, very entertaining.
Rory + Alex... Amaaaaazing chemistry!!! ❤️
The LEAF is a fun little car and an ideal commuter for many people. If you buy one just be sure to check the battery health.
Great Episode guys, very funny. Can u do the exact same episode with MG4. That will be great.
If the key was in the car, should have been able to power on to acc mode. Then hold foot on brake, into neutral and handbrake off. Leaf doesn’t like neutral with the door open though. As soon as the car rolls it jumps to park.
The cold snap was the first time I've driven my little e208 in sub zero. Can't believe the drop off in range. Went from 5 trips to work per charge to 2. Stuck with it for a 3 year lease but damn I have buyers remorse.
Don’t you return home between trips to work? What’s so inconvenient about plugging it when you’re at home?
I'm guessing the inconvenience of plugging in regularly is the inconvenience
Probably can't charge at home, is the problem?
@@_Rafiki.not to mention the cost of electricity at the moment
Bad luck, but you really should have done more research. You are obviously close to a worst case scenario for your driving profile if you see that much change.
my 2001 Corvette used to get 6 mpg on the track....and about 30 mpg on the highway. So, 5x the highway consumption.. The Leaf did relatively better. My 2019 Tesla Model 3 LRDM uses about 320 kw/m at 90...versus about 245 at 70 MPH.
In terms of air resistance, after a certain point, increasing speed uses exponentially more energy. Is there a way to find the optimal speed relative to the car's drag coefficient?
What a pair you two are, that was comedy gold.
I enjoyed this video. Having owned a LEAF, I had a personal interest in the outcome. As a matter of interest, what would the optimum speed on this racetrack be to get the maximum range?
I believe it would be around 18-20mph because of the lack of gears combined with the increased drag at higher speeds.
21.6 miles at 99 mph! That is actually very impressive for such an old car.
yeß
Lol. Compared to what ? A small 10 year old petrol car could do 300-400 miles as it would still have its full range. Electric cars are a dead end.
@@markm49 This is the worst EV. So it would be comparing all petrol cars equal to a 2CV
@@roland9367the dolly would still trump them
@@roland9367 even 2cv is better than the leaf
like in all petrol or diesel cars ....even electric cars use a type of 12 volt battery system for lights heater wipers indicators radio ect.
The early Leaf is well known for having a woefully inaccurate speedometer, whatever speed Nissan quotes as the maximum is exactly what it's capable of, I believe for the 24kWh Leaf it's either 87 or 89mph, thankfully Nissan improved matters with the newer Leaf, I've got a 2021 40kWh and relative to GPS my speedometer only over reads by 2mph at 70 and being a good boy I've never maxed it 😊
it happen to my old Nissan leaf open charging flat on top speed :O, twice :D
you should connect OBD2 adaptor and get real reading from app like LeafSpy.
My 2018 leaf with 12 bars of battery made it only 34 miles in -15f (-26c) on a full charge. The colder it is, the exponentially shorter the range gets.
Great video, loads of laugh 😆
Great video
Alex has great energy!
the astra electric rally cup in germany does about 40km on a full charge
Thumbs up for bringing Alex onboard
66 miles = 106 km
97 mph = 156 kph
24 miles = 38 km
Would love to know how much ground it'd cover at 80 mph or 130 kmph, the speed limit on most motorways in Europe
At 130 kmph it will be close to 64 kilometers with this exact Leaf with degraded battery or around 100 km when it was new in 2011. But fir generation of Nissan Leaf have quite high battery degradation, all the other electric cars have waaay less, only around 1 % per year. :)
@@drister007 ngl that’s still enough for daily stuff
Wish it was 80mph in the UK
Best duo on TH-cam
That was seriously impressive Nissan Leaf. So you never need to panic when the light starts flashing on a motorway.
Gotta say I’m really enjoying this two doing shenanigans together
I love the Nissan Leaf. For me is a beautiful car. Great test.
