Great review and test, someone did it finally. We really need highway consumption at 120-130 km/h though to be able to compare it with the likes of Toyota Rav 4 and Hyundai Tucson
Just ordered one as a replacement for our Hyundai Ioniq. It will be interesting to compare the fuel consumption figures in our driving cycles. Obviously a larger vehicle and not so aero dynamic however on our test drive we saw it register in the mid 50 mpg range (UK). Very smooth and quiet to drive. We have been converts to hybrids for 11 years so are very familiar with them. Drive them in the correct fashion they will return good consumption. The e-pedal I think is an interesting addition and logically should provide the best returns. The Toyota CHR and Hyundai Tucson returned around 50 mpg. The Prius gave around 60+ mpg as does our current Ioniq. Winter reduces these figures by around 10 mpg from our experience. The instant torque provided by the electric motor is excellent. Can't wait for it to arrive. 👍🙂
Just done our first trip in the ePower. 62 miles of varied driving conditions, town, single carriageway and dual carriageway with speeds up to 65 mph consumption was 51.5 mpg. Drive mode was initially standard then switched to ECO mode. The performance was more than sufficient. We will experiment with the various drive mode options as we get used to the car.
Coming from a diesel that barely manages 38, 50 would be more than enough for me. Heck, even a "low" 40 would be worth it, especially considering how kitted out the Tekna trim is compared to its competitors who are making everything optional extras so the highest trim is effectively identical to the base trim except for some stitching and different coloured grills.
Thats interesting. We too have an Ioniq HEV 2020 and have just test driven an epower. During an hours test drive we achieved 54mpg so like you we drove it as we would our own car on the same route. After the road test we went on the same route again in our Ioniq and achieved 64.5 mpg. I know the Nissan is not as aerodynamic but it has more modern technology and its mpg did not thrill me. We are also looking at the Renault Arhana full hybrid and a test drive over the same route in a mild hybrid version ( no full hybrid available for a road test) achieved 47.2 mpg. Is the Nissan epower really up to the hype ?
@@cb5110b mode absorbs the energy you'd usually expel as heat when braking and reuses it. In a regular combustion engine car you waste all the energy you created when building up speed as you brake, but with the epower, you reabsorb 85% of it and it's used to charge the battery. It's very clever tech! There's also the e pedal which is one pedal driving. They call it one foot driving but you only use one foot in an automatic anyway lol. Instead of switching to the brake when you want to stop, you just take your foot off the gas and the car slows down to a creep of 5 mph, really good for stop start traffic or car parks, not so much for regular driving though as it takes some getting used to how aggressive the braking from it is. I also really like the auto brake hold feature which keeps your brake pushed in for 3 minutes so you can take your foot off it, even on a hill! Technology is so cool haha
@@cb5110 that doesn't even make sense. Luca, the original poster, mentioned their own experiences with efficiency.

I am very interested in this next step up in SUV size, as I currently drive the smaller [non SUV] Nissan Note Nismo version [e-power] that has a smaller version of the epower drive train. The setup for the Note [think Honda Jazz size] is a 3 cyl 1.2L ice with 1.5kwH battery and inverter, overall power /torque is 80kW 280nM. Around town upto 60kmh this combination will do high 3 to low 4L/100kms [even with ac on] 26c outside. Highway runs I averaged 100-110kph for over 280km of driving 27c outside ac set to 25c as too cold lower, car returned average for that drive 22.8Km /litre or 4.4L/100. The worst Ive seen on mixed driving is 5L/100. The Note has a 40l tank only requires 91ron unleaded fuel and shows tank range mid to hi 800kms of range, for my driving. I'm sure around town for a tank I could easily do over 1000km a tank, but my area /driving is always a mix of highway, town and fun trips up into hills and mountains :) One pedal driving is fantastic might use the friction brakes once or twice on a drive. Overall e-power in a bigger form factor may mean my diesel SUV has found its replacement. Will see
Most people don't talk about the price of the car, and only talk about it doing more MPG than diesel or Petrol. At least in my contry this E-Power version is so expensive that you would need to do over 50k miles to even break even from the initial cost... it's just not worth it for this price unfortunately. I drove one for a month and it's realy realy realy realy nice to drive (loved it), has a lot of power and the silent electric mode is super cool, but it was NOT from the extra MPG that i would pay so much more for it over petrol...
Not having a gearbox and just using the electric motor for power is the intuitive way of doing things, but in reality at higher loads I believe the loses of converting kinetic energy from the engine to stored engine in the battery and back to kinetic energy to the electric motor don't seem to outweigh the gains from always running the engine at it's most efficient rpm and load when charging the battery. I could be wrong though, still an impressive figure. Would be interesting to see this set up with a more thermally efficient Atkinson cycle engine instead of an otto turbo.
Hey Richard, great to see someone in the comments section who is using their head. Really, no sarcasm here. Your assumption regarding the constant power conversion is right, BUT. TLDR warning, hybrid drivetrains are kind of complicated. If nissan's onboard power electronics and electric machines (the generator and the traction motor) are super efficient, like 98%, they might actually reach great overall efficiency numbers. Under higher load, the energy pathway actually is ICE-generator-inverter-motor-(some gears + differential)-wheels, we can expect that to the wheels we get like 94% (0.98x0.98x0.98) of what the engine is producing. For light loads, the energy path is ICE-gen-inv-batt.charge-batt.discharge-inv-motor-(g+d)-wheels. Let's assume the battery charge and discharge efficiency is 90%. Then our chain of individual efficiencies is 0.98x0.98x0.9x0.9x0.98x0.98 = 0.75. That seems pretty poor, BUT, lets not forget that under light load, a regular mechanical powertrain (ICE+gearbox) is terribly inefficient, because it is forced to operate in low efficiency mode. It simply is not possible to operate a traditional powertrain close to the engine's peak efficiency while stuck in traffic. So the reality is that if your trick ICE engine is like 40% efficient at peak, the overall efficiency of the vehicle, thanks to constant stopping and accelerating, let alone standing still, would be very lucky to get close to 20%. But the Nissan stored the energy produced at peak effy, so it is now getting it to the ground at 75% of the peak, that is 0.4x0.75=0.3. That's much more than 20%. So if this nissan is able to reach 4.4L/100 km with 30% effy, a regular car with average effy of 20% should achieve something around 4.4x0.3/0.2=6.6 L/100 km, which I think checks out pretty well. I also believe the powertrain is able to power the motor from the battery AND the generator (driven by the engine) at the same time, so the efficiency combines. But my education does not reach far enough to know precisely how this is done. www.nissan-global.com/EN/INNOVATION/TECHNOLOGY/ARCHIVE/E_POWER/ Contemporary honda hybrid system also uses a relatively big traction motor to provide power to the wheels exclusively, but in addition, there is a clutch pack in the driveline that is able to connect the engine to the wheels directly. But that only happens in higher speeds at close to steady state conditions. Effectively such system is able to switch from series hybrid to a parallel hybrid. Nissan's system is series only. Toyota's system is series-parallel, as it is able to merge these two energy paths. Atkinson cycle is one way of increasing efficiency. Modern turbo engines have a few tricks in their sleeves. For example, the output of the engine can be controlled not only by throttling, but by changing boost pressure. So under lower load, they actually dethrottle the engine AND lower the boost, which means the output is at the desired level, but achieved with higher efficiency. (I believe I read this in some VW EA888 whitepaper some time ago). This nissan's engine is able to adjust its (static) compression ratio, that is pretty unique. Oh by the way, I think you are using the term kinetic energy in a wrong context here. When the engine is used to rotate a generator, it is not the kinetic energy that is being converted. The (mechanical) work is being converted to energy. This work is produced by combustion forces of the engine. Kinetic energy is the amount of energy stored in the rotating assembly of the engine when it is rotating at given speed. It is a function of only the moment of inertia and the angular velocity, independent of the load on the engine. You can observe the kinetic energy in action when you turn off the ignition - the engine is still able to roll over once or twice. Cheers
@@cb5110 hey, thanks for the reply. I do not follow nissan's creations specifically, but the industry as a whole. Luckily there is a steady progress whether some like it or not.

A 2020 Hyundai Kona 1.6 crdi dct, basic diesel (without any mild or regular hybrid) would get the same fuel economy in the same route, I can qurantee you. This car might gain some economy due this hybrid system, but the real solution is BEV'a or at least a plugin hybrid, to be able go some of the range with pure ev mode with a battery not charged by burning oil.
@@1001cars good question and analysis. Kona has a nice performance (136 hp, 320 nm torque), very agile, 1.4 tons weight. Qashqai is more spacious for sure.. May be has better sound insulation which makes it heavier than kona.
Yes, but the point of e-power is also to deliver instant torque known from purely-electric cars. It's not only about fuel efficiency. Also diesel is way more noisy when it's idling, especially when it's cold.
The big question.. In city with a Corolla 2.0 hubrid you can to electric the 80% of the distance. 20-30-40km.. You use the motor only for the 20% of the distance. What is more efficiency in the city? The Hybrid Toyota or the Nissan?
I like the idea and the efficiency but my concern is the life expectancy of the small battery pack which is under a lot of load and frequent charge discharge cycles. How will this cope over time.
This is the exact same as in any hybrid or PHEV. Proper battery management and headroom would make the battery outlast the car easily... Only time will tell if they are doing that properly.
The power does not go through battery all the time. In this type of drivetrain, the engine is often sending power directly to electric engines, bypassing the battery (especially under heavy load). So there shouldn't be a big difference between this and traditional hybrid
When you do these fuel eco tests, do you drive as economically as possible without disturbing the flow of traffic, or do you just drive normally in eco mode? So what I try to understand is can an ecodriver get better results or is this more or less the best results achievable?
It is more like driving with other drivers but without speeding and of course with eco driving rules. It is possible to achieve better results usually, but probably with hardcore eco driving style :)
Thoroughly enjoyed the video was this the lower spec version with 17 inch wheels. Would'nt the consumpion drop if on the 19 or 20 inch wheels that are on the Tekna and Tekna+. Having a test ride in a N-connect tomorrow. Have you also done a consumption video on the new honda civic.
The gratest test I'v ever seen but You didn't use e-pedal. Why? Is it worse for fuel efficiency? I tested difference between computer and real consuption. I've tested mild hibrid qashqa and after 110km computer shows 6,9l/100km but when I counted real usage it is 7,45l/100km. We gonna buy e-power.
WARNING. We purchased a Qashqai E-Power Tekna + in Dec 2022. The car has now done 3500 miles and has been off the road for the last 3 weeks. Error msg appeared and we have another 10-12 weeks to wait for replacement Generator. Becoming a significant issue
@@theforge4591 yes, but new generator only has a warranty equal to the unexpired warranty on the car, so 3yrs less 1 yr old 2 years. Cost to replace generator was £11400
My ford focus sw 1.5 tdi 120hp from 2015 can do 4.4L/100kms. It would probabily do under 4L/100kms at this test, considering the speed and road profile. I understand the pleasure/ease of driving an electric car. But concerning efficiency and co2 emissions, this e-power seems quite desapointing.
D mode with using brakes is the same as B mode. If you know how to use both of them it is the same, but driving all the time in a city in B mode without thinking about it is less efficient (not applicable for cruise control driving)
As you could see on the video, this car can drive in pure electric mode. Also: it has EV button to force the electric mode. Talking about range in such car (this is not a plug-in hybrid) is pointless, but it can do up to around 4-6 km.
i have a 2022 Nissan Qashqai Manual Tekna (Mild Hybrid) 158bhp. Driving it in the UK. For city/town driving with normal traffic and a few hills, the best mpg i get is 30 to 35mpg (for average distances of 5 miles). Whereas driving the car in the motoray the best I get is 48.5mpg for (200 miles trip). I was wondering if you could let us know the epower Mpg just for city/town, driving < 30mph for most of the journey. I understand your average speed on this trip was 30mph but your overall mpg was a combined average including driving on the motorway. I was wondering if you could provide stats to highlight the difference between motorway and city/town driving.
Hi John, I've been yesterday to Nissan and look the same car as yours, but just looking for automatic. 30-35mpg that's really bad man. Nothing close to the spec's..... I start believe Nissan don't put right units of consumption. I bought Juke for my wife few weeks ago . Old model 62plate 1.5dci tekna manual. Really enjoy with it. But it's giving 35-38mpg in Birmingham. Far far away from what Nissan state for this car. Consumption is higher. I think 1.5 e-power maybe is better option then 1.3 mild hybrid.
Nie wiem co wzioles ale jezdzilem nissanem e-power powiem tak corolla cross przy nim wyglada jak woz drabiniasty jak mozesz bierz Nissana jezdzilem przez weekend rewelka
great consumption average, I really like this non plug-in hybrid engine... my audi a4 35 TDI 163 PS mild hybrid I would have beaten those consumption figures but I still think 4.4 l/100 km is a great average for a petrol engine
Diesel engines are more costly to maintain and they are noisy and smelly no matter how much money is spent trying to clean up the emissions. We have been driving hybrids since 2011 and wouldn't go back to a diesel powered car no matter how refined.
@@devenair681 diesel cars are way cheaper to buy and you have the option to include free maintenance service, diesel cars require about 7 tons of CO2 to be produced while electric cars require 18 tons of CO2 due to battery production mainly. Electric cars are just one more of the alternatives to reduce vehicle emissions but the technology still needs to evolve more and rethink about the whole life cycle of a car battery, meanwhile feel free to waste your money in EV, EV manufacturers need your money 😉
I think this still makes much more sense with a larger battery and a PHEV model. A 50 mile (80km) all electric range with this setup would be just about perfect for anyone who has mixed use local commuting and highway trips. That would only need about a 15kwh to 20kwh battery. Where does the cabin heat come from, waste heat from the engine, a resistive heater, or heat pump?
This is for people who don't have access to home charging. Larger batteries just mean more weight and nothing kills efficiency like extra weight. PHEVs are notoriously inefficient the way many people drive them, they are most efficient in town when charged at home, exactly where a full EV is better. This car is a "gateway" EV, the "secret sauce" is it is 100% powered by fossil fuels/ICE. The only other source of energy is regenerative braking. The marketing may be misleading because the engine will have to drive the wheels rather than the battery, albeit electrically via inverters.
@@saif1002 but also would give about an 80km range of zero gas usage which would cover most trips and would make even long trips more efficient up until about 800-1000km where the extra weight would catch up and make that less efficient.
'The reason Nissan didn't do a PHEV was they found that people don't, by enlarge plug them in thereby defeating the object. One also has to consider that not everyone has access to a driveway to conveniently park on to access a charging point.
Smaller ICE, bigger battery and possibility to charge from grid.. 60km pure electric and after that ICE charging/feeding electric motors at same time would have been right solution.
The whole point of this is that you don't need to plug it in. Not everyone has the luxury of a driveway and access to a charging port. Perhaps as the technology progresses and if/when housing regulations improve and enough homes are built for everyone (lol never happen) and governments get on with their multiple on every street charger plans, your suggestion may be a good idea. But as it stands, the only people that would benefit from your suggestion are the people who already have better options elsewhere.
If you know how to drive in B mode, than it does not matter, but using B mode you do not have to change driving modes all the time. You could see on the movie how I was driving in B mode.
what would be the consumption on 130kh/h speed and is it capable of using entire 140 kW of power for more than say 3 minutes due to such a small battery? and what is 0 to 100 when the battery is discharged? I supose it would be able to use about 100kW so the 0-100 time would be around 14 seconds
The battery can't be discharged. Think of the petrol engine as the "battery", the energi comes from the petrol engine whenever is needed. The battery is just a buffer. So you can do the same 0-100 km/h time and time again, as long as you have petrol in the tank. I think this is a very good idea especially for countries that do not have a developed charging infrastructure and also for people that can't charge their cars at home. It drives as an EV, but you don't have to plug it in, it get's rid of an auto gearbox, it should be cheaper to operate.
@@1001cars very interesting video. Is the digital instrument on the right hand side the instant consumption meter? What is its full scale value? And by the way, did you start driving from completely cold conditions? Thank you
@@1001cars well I am a bit confused. Speed is shown as a number, but I am referring to the semicircular range, that doesn't seem to be consistent with speed. Can you please clarify? Thank you
So, did the car average 64 mpg (UK) over the whole test? If yes then that is quite impressive for such a large/heavy car driving in a very urban environment.
@@1001cars Given the average speed over the distance travelled that seems about right. We have just taken delivery of ours but due to being sidelined by Covid have yet to travel any distance though this coming week we are away for a few days which should give us some idea of what to expect. Obviously we will need to try the different drive modes to make comparisons over time. We were always told to expect better mpg around town but our experience has been that we have achieved excellent returns on longer journeys. One thing I would note is that smooth driving and anticipation of road conditions pays benefits and obviously this applies to non hybrid cars too. I suspect that those who fail to achieve good fuel consumption would fail to do so in any vehicle. In any event given the excellent discount we got on the car we would be more than happy with a reduced figure however if we can achieve near these figures we would be very happy.
The trip computer is always lying. You need to fill the fueel tank, make the journey, and then refuel. Then, divide the liters used with the distance covered. This is the ONLY way consumption tests should be done.
I have just got my e-Power & it would have been better if you would have been speaking than all this speeding up & fiddling around. Not helpful at all.
I am still looking for the part where you are driving on motorway with 130km…you never drove over 90km per hour…of course you get 4.5 liter which is great…but most people don‘t drive like that.
I am still waiting until you watch linked in the end or in the description fuel consumption test in other scenarios. Tell me please: what is at 01:00? Is it over 100 km/h or am I sth. wrong with my eyes?

Atkinson cycle is one way of increasing efficiency. Modern turbo engines have a few tricks in their sleeves. For example, the output of the engine can be controlled not only by throttling, but by changing boost pressure. So under lower load, they actually dethrottle the engine AND lower the boost, which means the output is at the desired level, but achieved with higher efficiency. (I believe I read this in some VW EA888 whitepaper some time ago). This nissan's engine is able to adjust its (static) compression ratio, that is pretty unique.
Oh by the way, I think you are using the term kinetic energy in a wrong context here.
When the engine is used to rotate a generator, it is not the kinetic energy that is being converted. The (mechanical) work is being converted to energy. This work is produced by combustion forces of the engine.
Kinetic energy is the amount of energy stored in the rotating assembly of the engine when it is rotating at given speed. It is a function of only the moment of inertia and the angular velocity, independent of the load on the engine.
You can observe the kinetic energy in action when you turn off the ignition - the engine is still able to roll over once or twice.
Cheers
@@cb5110 hey, thanks for the reply. I do not follow nissan's creations specifically, but the industry as a whole. Luckily there is a steady progress whether some like it or not.
@@RedXczNissan could've put second gear ratio next to the reduction gear for the front electric motor to compensate for the higher speeds. That is my opinion. Honda setup is also good
A 2020 Hyundai Kona 1.6 crdi dct, basic diesel (without any mild or regular hybrid) would get the same fuel economy in the same route, I can qurantee you. This car might gain some economy due this hybrid system, but the real solution is BEV'a or at least a plugin hybrid, to be able go some of the range with pure ev mode with a battery not charged by burning oil.
Is Hyundai Kona the same size as Qashqai? Does it have the same amount of engine power?
@@1001cars good question and analysis. Kona has a nice performance (136 hp, 320 nm torque), very agile, 1.4 tons weight. Qashqai is more spacious for sure.. May be has better sound insulation which makes it heavier than kona.
7,9 sec Form 0 to 100 km/h, in the Qashqai. Epower is fun and fuel efficient.
Diesel have higher energy density than petrol so the Qashqai e-power is more efficient if the consumption is in the same ballpark.
Yes, but the point of e-power is also to deliver instant torque known from purely-electric cars. It's not only about fuel efficiency. Also diesel is way more noisy when it's idling, especially when it's cold.
The big question.. In city with a Corolla 2.0 hubrid you can to electric the 80% of the distance. 20-30-40km.. You use the motor only for the 20% of the distance. What is more efficiency in the city? The Hybrid Toyota or the Nissan?
e-power is less complex system -- this is main goal -- make is viable to produce without gov support and give a easy secondhand life
I tide in a lot of Toyota taxis which return about 4.5 ltrs per 100 km in the city centre.
ePower is no where near that.
Decent overall result but the highway consumption was pretty high considering the speed (~100km/h).
I like the idea and the efficiency but my concern is the life expectancy of the small battery pack which is under a lot of load and frequent charge discharge cycles. How will this cope over time.
This is the exact same as in any hybrid or PHEV. Proper battery management and headroom would make the battery outlast the car easily... Only time will tell if they are doing that properly.
mines done 84000 km still goes fine some have done over 100000 km this is the 2017 epower ver
The power does not go through battery all the time. In this type of drivetrain, the engine is often sending power directly to electric engines, bypassing the battery (especially under heavy load). So there shouldn't be a big difference between this and traditional hybrid
@@Glen799 100 000 is quite small number for a car.
Great question. At least it's a smaller battery so even if it wears out, it should cost less as a battery lifespan is never limitless.
When you do these fuel eco tests, do you drive as economically as possible without disturbing the flow of traffic, or do you just drive normally in eco mode? So what I try to understand is can an ecodriver get better results or is this more or less the best results achievable?
It is more like driving with other drivers but without speeding and of course with eco driving rules. It is possible to achieve better results usually, but probably with hardcore eco driving style :)
@@1001cars Thanks for this test. What about the e-Pedal mode? ain't it more efficient? did you try it?
e-pedal lower do efficiency in the city.
Thoroughly enjoyed the video was this the lower spec version with 17 inch wheels. Would'nt the consumpion drop if on the 19 or 20 inch wheels that are on the Tekna and Tekna+. Having a test ride in a N-connect tomorrow. Have you also done a consumption video on the new honda civic.
All hybrids are made for city drive..... On the highway 100kmh..... That's it
i have the previous model diesel 1600cc 130 hp with better consumption at the same speeds..so the e-power is just more powerfull! :(
The gratest test I'v ever seen but You didn't use e-pedal. Why? Is it worse for fuel efficiency?
I tested difference between computer and real consuption. I've tested mild hibrid qashqa and after 110km computer shows 6,9l/100km but when I counted real usage it is 7,45l/100km. We gonna buy e-power.
Thank you :) e-Pedal in reality is only stronger B mode :)
WARNING. We purchased a Qashqai E-Power Tekna + in Dec 2022. The car has now done 3500 miles and has been off the road for the last 3 weeks. Error msg appeared and we have another 10-12 weeks to wait for replacement Generator. Becoming a significant issue

@@theforge4591 yes, but new generator only has a warranty equal to the unexpired warranty on the car, so 3yrs less 1 yr old 2 years. Cost to replace generator was £11400

@@aykutasilturk2912 12 lt for 100km for the epower? At 130/140 km/h?
My ford focus sw 1.5 tdi 120hp from 2015 can do 4.4L/100kms. It would probabily do under 4L/100kms at this test, considering the speed and road profile. I understand the pleasure/ease of driving an electric car. But concerning efficiency and co2 emissions, this e-power seems quite desapointing.
I've noticed u switched from D to B and from B to D few times during the ride. Does it have any effect on fuel consumption?
D mode with using brakes is the same as B mode. If you know how to use both of them it is the same, but driving all the time in a city in B mode without thinking about it is less efficient (not applicable for cruise control driving)
My Quashqai 1.5 L diesel automatic (yes automatic) averages 55 mpg with mixed driving. Can the new Quashqai hybrid better this?
I can try to find the answer only if you tell me which mpg (UK or US) and what is "mixed driving", in what proportions? :)
Does it ever go into electric only mode or does it have an EV only button? If so how fast can you go on it and what’s the range? Thanks.
As you could see on the video, this car can drive in pure electric mode. Also: it has EV button to force the electric mode. Talking about range in such car (this is not a plug-in hybrid) is pointless, but it can do up to around 4-6 km.
Well made video. Thx.
i have a 2022 Nissan Qashqai Manual Tekna (Mild Hybrid) 158bhp. Driving it in the UK. For city/town driving with normal traffic and a few hills, the best mpg i get is 30 to 35mpg (for average distances of 5 miles). Whereas driving the car in the motoray the best I get is 48.5mpg for (200 miles trip). I was wondering if you could let us know the epower Mpg just for city/town, driving < 30mph for most of the journey. I understand your average speed on this trip was 30mph but your overall mpg was a combined average including driving on the motorway. I was wondering if you could provide stats to highlight the difference between motorway and city/town driving.
This is how my normal fuel consumption tests look like: th-cam.com/video/HkVr0sCDtOU/w-d-xo.html I am going to prepare similar for e-power :)
Hi John, I've been yesterday to Nissan and look the same car as yours, but just looking for automatic. 30-35mpg that's really bad man. Nothing close to the spec's..... I start believe Nissan don't put right units of consumption. I bought Juke for my wife few weeks ago . Old model 62plate 1.5dci tekna manual. Really enjoy with it. But it's giving 35-38mpg in Birmingham. Far far away from what Nissan state for this car. Consumption is higher.
I think 1.5 e-power maybe is better option then 1.3 mild hybrid.
@@cb5110 you're right sir 100% and i understand that. Waiting for more videos of the E-power system. :)

Recuperation
e-Power e-4orce would fit here great. To bad it's only available on Xtrail
great consumption average, I really like this non plug-in hybrid engine... my audi a4 35 TDI 163 PS mild hybrid I would have beaten those consumption figures but I still think 4.4 l/100 km is a great average for a petrol engine
Diesel engines are more costly to maintain and they are noisy and smelly no matter how much money is spent trying to clean up the emissions. We have been driving hybrids since 2011 and wouldn't go back to a diesel powered car no matter how refined.
@@devenair681 diesel cars are way cheaper to buy and you have the option to include free maintenance service, diesel cars require about 7 tons of CO2 to be produced while electric cars require 18 tons of CO2 due to battery production mainly. Electric cars are just one more of the alternatives to reduce vehicle emissions but the technology still needs to evolve more and rethink about the whole life cycle of a car battery, meanwhile feel free to waste your money in EV, EV manufacturers need your money 😉
Not even released yet how come you got it
I think this still makes much more sense with a larger battery and a PHEV model. A 50 mile (80km) all electric range with this setup would be just about perfect for anyone who has mixed use local commuting and highway trips. That would only need about a 15kwh to 20kwh battery.
Where does the cabin heat come from, waste heat from the engine, a resistive heater, or heat pump?
This is for people who don't have access to home charging. Larger batteries just mean more weight and nothing kills efficiency like extra weight. PHEVs are notoriously inefficient the way many people drive them, they are most efficient in town when charged at home, exactly where a full EV is better. This car is a "gateway" EV, the "secret sauce" is it is 100% powered by fossil fuels/ICE. The only other source of energy is regenerative braking. The marketing may be misleading because the engine will have to drive the wheels rather than the battery, albeit electrically via inverters.
20 kwh battery will increase weight by 220kg and drop 7 mpg.
@@saif1002 but also would give about an 80km range of zero gas usage which would cover most trips and would make even long trips more efficient up until about 800-1000km where the extra weight would catch up and make that less efficient.
'The reason Nissan didn't do a PHEV was they found that people don't, by enlarge plug them in thereby defeating the object. One also has to consider that not everyone has access to a driveway to conveniently park on to access a charging point.
Fuel consumption at 140 km/H on the Highway would be interesting
I will check it next time :)
just “a lot” 😔
6l
Smaller ICE, bigger battery and possibility to charge from grid.. 60km pure electric and after that ICE charging/feeding electric motors at same time would have been right solution.
The whole point of this is that you don't need to plug it in. Not everyone has the luxury of a driveway and access to a charging port. Perhaps as the technology progresses and if/when housing regulations improve and enough homes are built for everyone (lol never happen) and governments get on with their multiple on every street charger plans, your suggestion may be a good idea. But as it stands, the only people that would benefit from your suggestion are the people who already have better options elsewhere.
You drove most of a car at B, I think at D that will give you more fuel efficient. Whats the science behind this ?
If you know how to drive in B mode, than it does not matter, but using B mode you do not have to change driving modes all the time. You could see on the movie how I was driving in B mode.
what would be the consumption on 130kh/h speed and is it capable of using entire 140 kW of power for more than say 3 minutes due to such a small battery? and what is 0 to 100 when the battery is discharged? I supose it would be able to use about 100kW so the 0-100 time would be around 14 seconds
I will check the consumption at 120 and 140 km/h soon. About acceleration: you cannot in normal conditions discharge the battery completely.
The battery can't be discharged. Think of the petrol engine as the "battery", the energi comes from the petrol engine whenever is needed. The battery is just a buffer. So you can do the same 0-100 km/h time and time again, as long as you have petrol in the tank.
I think this is a very good idea especially for countries that do not have a developed charging infrastructure and also for people that can't charge their cars at home. It drives as an EV, but you don't have to plug it in, it get's rid of an auto gearbox, it should be cheaper to operate.
@@1001cars very interesting video. Is the digital instrument on the right hand side the instant consumption meter? What is its full scale value? And by the way, did you start driving from completely cold conditions? Thank you
@@1antastik If I understood you correctly, there is no instant consumption meter. On the left side is power meter, on the right side vehicle speed.
@@1001cars well I am a bit confused. Speed is shown as a number, but I am referring to the semicircular range, that doesn't seem to be consistent with speed. Can you please clarify? Thank you
tldw: very efficient at low/city speeds. not very efficient at higher speeds, above 100kph.
So, did the car average 64 mpg (UK) over the whole test? If yes then that is quite impressive for such a large/heavy car driving in a very urban environment.
As you could see, the car achieved 64,2 mpg UK on whole distance.
@@1001cars Given the average speed over the distance travelled that seems about right. We have just taken delivery of ours but due to being sidelined by Covid have yet to travel any distance though this coming week we are away for a few days which should give us some idea of what to expect. Obviously we will need to try the different drive modes to make comparisons over time. We were always told to expect better mpg around town but our experience has been that we have achieved excellent returns on longer journeys. One thing I would note is that smooth driving and anticipation of road conditions pays benefits and obviously this applies to non hybrid cars too. I suspect that those who fail to achieve good fuel consumption would fail to do so in any vehicle. In any event given the excellent discount we got on the car we would be more than happy with a reduced figure however if we can achieve near these figures we would be very happy.
10:37 What is this bitch move though? :D
Hey, it's in B mode, so bitch moves are allowed 🤪
The trip computer is always lying. You need to fill the fueel tank, make the journey, and then refuel. Then, divide the liters used with the distance covered. This is the ONLY way consumption tests should be done.
Check my videos with this car. Hint: the trip computer is not lying (much) :) th-cam.com/video/bZfr8NRa8kQ/w-d-xo.html
