7.5 l /100 km 140 km/h with 3 ppl onboard

@@MJProductionPL i had the previous model diesel 1600cc 130 hp with better consumption at the same speeds..so the e-power is just more powerfull! :(

How is it after a year?

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 you didn't ask about fuel efficiency though. You mentioned his, but at no point did you ask about it. You didn't ask about anything.

@@cb5110 that doesn't even make sense. Luca, the original poster, mentioned their own experiences with efficiency. You then mentioned you'd heard of the b mode (with no further information) and also noted the efficiency in the video. At no point did you ASK anything. Of anyone. I don't know what you think is supposed to be an indirect response here, since there were only the two replies I just mentioned.

it seems to be quite a large consumption, can you detail other aspects? consumption in the city, outside the city, the feeling, in general, are you satisfied with the purchase? thanks

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.

​@@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

still in warranty?

@@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

Thank you :) e-Pedal in reality is only stronger B mode :)

e-power is less complex system -- this is main goal -- make is viable to produce without gov support and give a easy secondhand life

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.

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.

I will check it next time :)

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.

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)

I will make it next time :)

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? :)

This is how my normal fuel consumption tests look like: kzfaq.info/get/bejne/ftGGpZOkqKrYf4k.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. :)

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.

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 😉

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.

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.

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.

Recuperation

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.

Hey, it's in B mode, so bitch moves are allowed 🤪

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.
