View Full Version : Nissan Leaf

Hello and welcome to another one of my self indulgent rambles :) (you never know, someone might find them interesting)
Today I finally got around to test driving a Nissan Leaf (and yes, I know this is a motorbike forum but there are a lot of geeks in the crowd, maybe even some (environ)mentalists).

I'd wanted to try an electric vehicle for a while after following Robert Llewellyn on twitter (@bobbyllew) he is big into his green motoring and such and has tried and reported on lots. Finally the Nissan leaf was released to the unwashed masses and people could get a test drive, well not really, you could get a 90 second spin around a car park with a rep. I'll pass thank you.

I checked last week and they had a second round of "roadshow" events but also had another link to test drive it at your local dealer. :cool: Put my name down and got one booked, a guy from the garage called me back and arranged it, all I had to do was wait (curses, I don't do waiting very well).

Our nearest dealer was Stockport, a bit of a trek but I fancied giving it a go. Headed out there today with driving license in hand, expected the place to be empty given that it was for an hour before the FA Cup kicked off but apparently not :( lurked around for a few minutes and perused the other models then the guy I'd spoken to came over and after a few questions and a copy of my driving license we were off!

Playing it cool on the outside asking the right (geeky) questions but inside like a kid at Christmas getting a go on someone else's coveted toy. :D
The guy reversed the car out and gave me a quick guide as he did so, I was glad he got it off the car park as it seemed pretty mountainous! built on a bumpy hill but off we went, my wife and stepdaughter in the back.

The car gets powered on and is somewhat reminiscent of a nokia phone, it makes a welcome noise to tell you its done and the screens display things and at that point its ready, simple as that, no juddering as the engine settles to idle, no noise from any components. OK so here we go then...

There is no gearbox or gear lever but it's not an automatic, automatic means it changes gear automatically, there is no gear to change in this of course. This makes power delivery unbelievably smooth, almost unimaginably so, it takes some getting used to. By the end of our 10 mile(ish) drive I was still marveling at it.
I had mercifully driven a colleagues automatic A3 sportback back from Bristol yesterday so my left leg was primed to do nothing. Foot on the brake and move the "joystick dooberry" across and forward to put it into reverse. The reversing camera comes on and shows you where you are going to end up, quite nice. Push the joystick dooberry across and backwards and you are in drive, but take your foot off the brake and nothing happens. (in an automatic it would idle forwards)
I tentatively pressed the accelerator, feeling like a learner all over again. Expecting at any moment to get kangaroo juice or something but nope, nothing like, it was so smooth and silky to pull away, there was no dead zone on the throttle like in either auto or manual cars where you rev and feel for the bite etc. It is just there right from the first millimeter of movement, it sounds a little odd but its quite reassuring.

Once you are in motion the next thing you notice is the absence of any noise from the engine or vibration that you expect and subconsciously gauge speed from, it glided down the streets and I pulled out onto a main road with an oncoming car without any qualms that it might be slow or lag when I pressed the go pedal. (I'd have been apprehensive in some auto cars I'd driven and even in some cases engages sport mode heh)

Right, I've settled down with how it performs I don't need to pay too much attention to it so I can look around the dash, there are displays for your battery level and its expected range from this. The range is useful but less so if someone else has been driving it as it estimates based on their habits so in a test car it isn't so handy but the battery meter is fine, 3/4 charged, I barely used any despite my heavy footed, ham fisted approach to it today. There is a display of a tree to indicate how well you are driving, the tree fills up and then gets added to a small forest you can accumulate to the side. Now I realise how cheesy that sounds but it is actually a very good tactic and idea, it makes you aware of how you are driving and it makes you want to complete the tree and better yourself. Definitely designed for the Nintendo generation, conditioned for digital rewards. You can even go online and contribute your trees and compare I'm told.

I didn't get chance to test the "turbo" section of the go pedal as it was on city roads and I was accompanied, but I'm told if you press the pedal down and it feels like it stops, press it some more and it sort of clunks into the final section which drains the batteries fast but really shifts!

It feels (and is) a real car, It doesn't feel like a toy or anything different as you drive it around. Size wise, it's not too dissimilar from our current Peugeot 307, perhaps a tad roomier but the boot is smaller. The headlights are LED looking at the specs, not sure how they perform as it was the middle of the day but I'd imagine they are sufficient if not better then normal bulbs.

Audio and IT kit.
The Leaf is choc full of gadgety goodness, it has iphone/mp3 integration built in, bluetooth, satnav, reversing camera and air con all as standard. The navigation also shows nearest charging points and will update the list from satellite as this is an ever changing list. Along with this there is also a feature called CARWINGS, this lets you connect and interact with the car remotely. (sadly not like knightrider but thankfully it also doesn't have a camp voice either) You can use your iPhone (probably other smart phones) or PC to check on the charge level, start or stop charging, initiate AC to get the correct temperature before you start depleting your batteries or plan your route and upload it to the satnav in the car (how cool is that, google maps integration and I'd be sorted!)

The price is £25k after a £5k government grant. I was looking at the price on the way to drive it as a lot of money but typical fare for early adopters, and that's what this car is, the first generation. But still, £25k will get you a good deal of car, I was checking around the show room, a 2.0 Qashqai
was 22k, a Nissan Note was 13k, almost half that of the Leaf and not significantly smaller. The Leaf was starting to look like an increasingly bad financial proposition at this point, compounding my preconceived opinion.
But after testing it and the sales guy mentioning one startling revelation that you will never need to visit a petrol station again, it starts to look a little better, hmm maybe its not just for carbon abhorrent hippies then....

Charging.
A normal charge using a home installed "power pod" I think they call it, will take 8 hours, so you could drive 100 miles in a day, come back and charge it while you sleep, simples.
If you take it to work or visit a friend you can use a typical 3 pin plug lead and it will charge in 12 hours.
Or, call at your local Nissan dealer and charge it on their fast charge point in 30 minutes. (this gives an 80% charge)
The advice is the same as most batteries, charge it, use it till almost flat then recharge. If you drove only a few miles a day and put it on charge every night you would shoot yourself in the foot with regards to the battery longevity.

Personally I don't see charging as too much of an issue, its like anything else, if you plan for it, it isn't a problem. Charging points are becoming more common and lets face it, electricity is everywhere already, its just a matter of getting the hardware in place to plug in. I can see Nissan or other car dealers partnering with a major coffee shop chain to get a small coffee bar in their dealerships (where there isn't one within 100ft already!) so that customers can park up and take a quick charge and have a coffee.
Also NCP could install 5-6 bays in their car parks (they already have lights in there so just take a feed) and charge a small surcharge on the existing parking fee, you are likely to be there for some time anyway, thats my prediction anyway. Hotel chains will be announcing deals with charging point installers soon too I suspect, some small private ones already provide this.

Some quick ponderings on the way back and I came to the conclusion that its a 15k car with a 10k upfront fuel charge. That is the best way I can find of looking at it, and doing so, it makes sense, even for normal people, right now. If you spent that £25k on a 2.0l Qashqai, you would then spend 5-6k on a drip feed to keep it running that year, its an accepted cost and we are conditioned to it. Like a loan that has been running for years you expect to have this chunk of your monthly income gone so you work around it. If you could pre-pay £10k to fix your tank fill up cost to £5 for the life of your vehicle I bet you would jump at the chance looking at the current fuel prices. Incidentally, filling the batteries on the leaf should cost less than that on most electric tariffs.

OK, back down to earth, when all said and done, this isn't the savior on four wheels, it's the first generation iPod, expensive and uncommon. But this will fund the second generation which was better, cheaper and more usable. It's the first step, it won't be taken by many but I find it very interesting.

I'm not driven (no pun intended) by the need to be green, I don't even mind that my electricity to fuel one would come from the usual coal fired station. The argument is moot as petrol requires the same electricity to refine it, coming from the same source so the way I see it, they cancel each other out. When EVs really take off, we will be looking for better ways of getting the electricity so it will naturally come about, people will come up with cheaper ways in the inevitable price war that drives most industries and technological advancement. My main attraction to EVs (2 or 4 wheeled) is that of a geek, they interest me in a technological way. Electric seems to make the most sense for getting around, its just the charging and storage of that electricity that is holding us back at the moment.

Anyway, if anyone still is, thank you for reading. I don't mean to sound like an electrical zealot but I'm very enthused by trying this out today. I know it isn't for everyone, but even me as a rural located driver could make use of one as I have a short commute (15 miles) and our shopping/family visits are all less than the 109 miles quoted range by quite some margin (even factoring in getting back before being able to charging it) After trying this today I'd be very interested in trying one of the Brammo electric bikes or similar! :cool:

Ooh, almost forgot, heres a picture of the car I tried:

i enjoyed that read, nothing to do with the fact that the lady is watchin eurovision ;)

but was a good read nonetheless. i have a feeling that the go faster pedal would feel alot like the pedal on a forklift truck, no roll forwards when the brake is disengaged but just put the weight of your foot on the pedal and it will creep forward.

just wondered, can you hear the whine of the electric motor or is it near as damnit silent??

Brettus
14-05-11, 08:04 PM
Yeah I had hoped to corner the captive eurovision refugee audience ;)

The motor is silent for all intents and purposes, there is a very slight whine but is only barely audible when accelerating quite hard. Apparently it has the exterior noise maker for idiot pedestrians but I also couldn't hear that. Even at motorway speeds I was pleasantly surprised how quiet it was, road noise is a big part of the noise in any car but this has that chunk less and has no vibration that is ever present in normal cars, we are so used to it we don't really notice it but you do notice the absence of it.

I'd imagine it is pretty comparable to a forklift in terms of drive as I've seen them pick up and go (again no pun intended ;)) but I'd imagine ride comfort is higher heheh, and weather proofing.

I'd love one.
Too expensive for me at the minute though.

100miles tank range isn't very good though. For example 90% of the time It would be fine, but there is times where I need to travel more than 100 miles 1 way. I can't stop and charge my battery just to get to my destination. It's too inpractical right now.

They need to do what Chevvy did and whack a small fossil fuel engine for the times where you need to travel any real distance.

what they really need to do, is find a way of storing more and more electricity in a smaller space. the eurovision refugees applaud your entertainment :)

Yeah I completely agree on that, the Chevy isn't a bad option, its another option. For the people it will work for, the Leaf is the purest solution (that has been released so far of course). For those needing something more versatile the Chevy Volt is the next best thing. After all "electric" trains have been using diesel engines for years, they use the electric engine more as a gearbox to get the power to the wheels. They are still quite big steps away from purely internal combustion cars and a I can't wait to see where we go from here.

I read an interesting point that the future of EVs isn't in battery tech, more likely its in capacitors, very quick to charge when needed and much lighter than current batteries. making stops more equivalent to your petrol stops now. Interesting times, I wonder how many said the Model T would never catch on, "where will you find fuel for something like that?" etc.

Interesting, but i cant make the figures stack up,

I spend £2000 a year on fuel, and what would the car be worth in 5 years which is what it would take to pay back the 10k extra cost from a year old ford focus tdci..

add to that 100 miles at a time, what use is that to the current car user? those who only do a few miles are being pushed to sell because the costs are now massive, how wud paying 25k for a car suddenly see,m a decent investment?

so what is their demographic?

add that to the fact i bet it has lithium batteries which all the present evidence indicates the life co2 is still hideous, hardly green is it, let alone the civil and human unrest regarding the lithium mines.

now lets actually realistically try and get hydrogen cars off the mark shall we..?

ps.. nice write up

All valid points, sorry for the quick fire responses, I'm over enthused today ;)

I suspect you are right about the batteries and I'm not arguing against anyones points, I quite like to hear others and learn when I'm wrong.

Hydrogen and such is where it is likely to end up but I don't think we can go directly to there, I think there needs to be this EV stepping stone, and this is the first step on that I think. Clive Sinclair envisioned all this in 1980 but couldn't make the technology stack up, now we are just beginning to make it work, barely, for some people. And it is those eco friendly evangelists who will pay the premium for the car and help fund the Leaf 2.0 which will lead us to the hydrogen utopia but we can't leap frog this stage I think. LPG never took off because of the delivery network, hydrogen will suffer the same thing until it can be produced cheaply enough and easily enough to be available everywhere.

Electricity is already there, just needs storage on the move.

Does it have a heater? - and if so I wonder how having the heater on affects the range, assuming needing something like at least 1kw to make an impression on a winters morning.

Yup, has aircon and yes it can affect the range, I heard as much as 20%. but it has a scheduler to allow it to get up/down to temp before you set off in the morning, so it just needs to maintain it. Doesn't help though when it's been sat in the sun all day though, will need to counteract that.

I can't help but feel the Batteries in these cars will wear out like the ones in your iPods, Laptops and TV remote and eventually will be doing 50 total before needing a good longer charger after a matter of Years and I bet changing these will not be a simple local garage think at this point so as it stands I feel like technology like this is a great idea I just hope they actually come up with long term solutions and not temporary hot topic answers. Essentially most of our Electric is still from fossil fuels too.

Thats my rather poorly written opinion on this but I will say the car isn't ugly so atleast it has that going for it

Morning All,
I'm glad I posted this yesterday, some interesting debate and points raised. I'm unlikely to be in the market for a leaf in all honesty, I don't fit the demographic as I live rurally. I do about the same mileage as is required but that said, the demographic is quite a niche one at this stage. People who can afford to spend £25k on a car, don't do more than 100 mile journeys very often, are clued up enough to find their own charging points and who will drive it economically. Essentially I'd say this small group is covered by the term "Enthusiasts" it will be made up of people who are interested in it, whether it be for its eco friendlyness or its technological appeal, those early adopters willing to pay for it.

The hardly cheap Prius sold by the bucketload when launched as it was THE green credential car to be seen in. Some people will buy into it because its interesting and they have enough money not to worry about doing so. It isn't a mass market suitable car, despite what Nissan may be saying. It's just available to the mass market, which in itself is a first. Mitsubishi and Peugeot are hot on their heels with an impending release of an EV each but as alluded to by YellowMonkeyBoy, they are hardly good looking. The Leaf is just different enough to not look like everything else but not different enough to look out of place I think (of course this is all IMHO and you are welcome to disagree)

Apologies for the length of the post but I've slept on it and pondered a lot before drifting into sleep.

Batteries are definitely an issue, I suspect YMB is right once more with the fact that they won't hold up to the 10 year life touted by Nissan but they are also slightly different than your laptop and phone in that because its a bigger device and bigger investment, you will treat it differently. How many out there can vouch for never leaving their phone on charge all night every night or charging their devices before they are due "just to make sure"? In terms of planning to charge and adapting our journeys it is more of an electrical appliance than a car but because it is a car in size and mentally for maintenance, I think we will treat the batteries better. I would if I owned one and I shamelessly confess I'm awful to my handheld gadgets.

One last note re the charging and aircon. The leaf isn't a micra with an enginectomy and bodykit, because the leaf was designed as an electric car from the beginning it has some intelligent features. The charging only happens when you tell it to, plugging it in doesn't make it charge on its own. So you have two options. Set it on a schedule to take advantage of the modern equivalent of Economy 7 electric tariffs and get a full charge for less than £2 (Nissan quote £1.30 but I'll treat that with the pinch of salt it deserves) or you plug it in and manually set it charging so you can actively manage it.
The same goes for the air conditioning, as rightly pointed out, heating or cooling requires a lot of energy, something which is limited to what you can bring along in the Leaf. As mentioned you can schedule the heating/cooling to get the car to what temperature you would like, so that if you always set off at 08:30 and you would like your car at 19c it will use the charging lead and mains electric to be there ready for you without discharging your battery to get it to that temperature. Also, you can remotely control this feature, so if you don't have it set on a schedule but you wake up and its brass monkeys outside you can set it from your PC/iPhone and let your car get to temperature (without having it unlocked or and engine running) while you have your breakfast.

Anyway, enough gushing from me. If you have a vague interest I'd say get yourself to a garage and give one a go, even if it is just to see what one feels like as in my case. I bet you will be impressed.

Mr Speirs
15-05-11, 08:37 AM
I just took a look at the chevy volt and as a concept it is good however I didn't realise the electric range was 37miles. Although actually that would still save me money 90% of the time.

I really want a car manufacturer to make a car with a small diesel engine and an electric drive too.
The electric part would be charged by outlets on the wall, regenerative braking and also from the diesel engine.
Heres how I see it working:

Acceleration would be done solely by the electric part of the car.
Constant speed would be handled by the diesel engine, when this is happening the battery for the electric motor would be charged.

Therefore the electric motor will always be charged and ready to accelerate the car.

As another observation I believe if electric cars are to be successful they need easily removable fuel cells. Essentially petrol stations will swap the batteries out giving you a full battery again. Unless energy storage gets to the point where you can get 400miles to an 8 hour charge I think at the minute it's the only way to make electric cars viable.

It's quite a specific thing for cells to develop a memory, half of the knackered cells in electronics are just knackered from age or damaged by deep discharge etc.
Even the "well known" NiCd memory turns out to be based on one report of a battery on a satellite which was very exactly charged and recharged over a fixed range, a full cycle of the battery apparently left it without any memory effects.
But with price of these batteries, which I'd imagine is a fair chunk of the whole car, I reckon chargers will be more advanced.


Regarding temperature, it's one advantage of a conventional vehicle that the heat is recovered where it would otherwise be wasted. Very little impact on the total efficiency though.

Oooh, now thats an interesting thread. (and forum, damn you YC for giving me ideas) I did a quick scan of the first few pics and thought that motor didn't look big enough for a car so maybe a small cart or a bike was gonna be done but nope I was wrong. One of my other ponderings overnight was... I wonder if YC could give a curvy the EV treatment :D

I think a bike would struggle to have enough batteries packaged in there for reasonable range and speed.
That's going on using lead acids, like Anon. I've actually got access to hundreds of them, but like I say, packaging, what does 100Ah weigh, 35-40kg? It's a hell of a mass to lug about.

If I had to electrify something I would only do it to a kawasaki, curvy does not deserve that treatment :-P

Like all electrics vehicles. They have thier positives and thier negatives.

An aquaitance has just bought a Leaf. However, i still do not think that electrics cars are the way forward. We do need an alternate source, but batteries are not it.

Good review

£25k for this? Someone is having a Laugh.

The fault here is that technonlogy is the problem and somehow technology is the solution.

You can buy a Citroen or Peugeot C1/107 for less than £7k brand new and it is a far better 'green' car than this. And the range is how much petrol you can fit in.

Unless the electric car can match perfectly the Petrol/diesel then this is just another PR stunt to show how Tree hugging Nissan is.

hmm, but how do you jump from an emerging tech to being petrol diesel beating WITHOUT having something like this?
The Tesla EV is £80k, making this a bargain, there are a couple more coming but this is a start.

The point with this is you put NO petrol in it, that is what needs to change ultimately. Just because you slow down when running out of road doesn't stop you hitting a wall, you need to stop. Eventually we will run out of these resources so at some point we need another solution.

Each to their own opinion though of course.

£25k is no bargain in my book.

Energy is not free. Fossil fuels have to burnt at the power station rather than in a combustion engine but they still have to be burnt somewhere to produce energy.

The idea of Zero emissions is the biggest joke I ever heard.

Put no petrol in it but shove the coal on at the power station.

Not my opinion...Stone cold fact.

Each to their own opinion though of course.I agree with you, as i said, that there needs to be a viable replacement for fossil fueld vehicle. Electric cars are far from being environmentaly firendly; first off in thier construction. Lots of too'ing and fro'ing for the battery creation, along with the same amount of energy in making the shell. Ok, so you get cheap running costs, and again these are not free of fosil fuel usage to create, but understand that its less that a single car and its own emissions. The massive issue i do have hower is that EVERYONE that has one will have to compromise on how and what they do. A Leaf does not have enough range for me and my family of 3 (Say) to go to the coast for the day. Fine if you can find a charging point at the coast but they are not as popular as you think. Buying an electric car is more of a statement and a lifestyle choice more than buying a car.

I really do think that Hydrogen is what the world should be focusing on. It keeps the car as we know it. We drive. We get low on Hydrogen. We filll up in minutes, then we continue our journey. Thats how we as a species have emmbraced the invention of the car and thats how it should be. Leccy cars are far from being good, far from being a viable alternative to petrol vehicles. I would think of buying a Hybrid but not a full leccy car

And where would the Hydrogen come from?

The only true 'green' solution to the car is to have no car.

Just how do you think they produce the electricity required to power these wonderful newfangled and ecologically sound electric cars, do power stations run on fresh air nowadays?

Just how do you think they produce the electricity required to power these wonderful newfangled and ecologically sound electric cars, do power stations run on fresh air nowadays?

There's a pay-off, and it's not cheap in the case of electricity.

But the petrol you use has already had the same (if not more) electricity used in it's refinement, so with petrol you are using BOTH amounts of energy already, whether you want to or not.

But I do admit it's far from ideal, just suitable for some at the moment, I just find it interesting. Really glad I went on the test drive and was impressed anyhow.

I've posted here on this subject before, and I'm not going to repeat what I think about low carbon, zero emission brainwashing and environemntal claptrap. Maybe I just did, anyway -


"Look at our lovely green zero emmisions car. Its going to save the world" - right upto the point where the huge batteries end up in landfill. Not very environmentally friendly now are we?
Being 'environmentally friendly is about more than burning stuff to make energy.


AND its called 'the Leaf'. Thats way too pretentious.

Oil refining would still go on due to production of plastics and other oil based products. Shipping and aiplanes and trucks will still need Fuel oil and kerosene and diesel so that will go on.

If suddenly all cars had electric motors then the power stations would suddenly have to markedly increase production.

A quick look on the Nissan Website and they also make the GT-R..a 3.8 litre V6 that runs on good old gasoline. Talk about Hypocrisy.

No body really cares about the environment or their emissions... But plenty of people moan about fuel prices, which are only ever going to get more expensive as reserves reduce.

At least if you had an electric car you could employ a slave to sit riding a bike all night powering a generator to charge it... Worst case you understand.

Sure the technology is expensive and not justifiable to most right now... But neither was a petrol vehicle many moons ago when most people had a horse and cart... Now you can have a petrol car even if your poor and on the dole. You always have to work towards alternatives.

That's how development is made and the world progresses... We would still have people dying of minor ailments if some companies hadn't spent vast fortunes trying to find the latest thing, mistakes are made on the way and some interim solutions arnt the best but they usually get there in the end.

It seems at the moment that the only viable solution is what we already have, burn some flammable liquid. Seems to be the only possible way to package the necessary energy.

There has got to be a possible process to reform hydrocarbons from CO2 and water, using some clean power, like nuclear.

I have no idea how you'd fit sufficient hydrogen in a vehicle to do much, transferring very high pressure gasses is really not something you want to do on a forecourt.

Were be having battery's made in Washington , Newcatle in 2012. And the leaf assembled there as well.
It's very well put together and it's greener than a petrol . For city stop/start it's in it's element.belting down the motorway is not it's thing.
The HV battery pack is made up of serviceable elements so it's not as un friendly as you think regards re cycling.
Just the limited range is it's stumbling block.
Ps hold your foot on the brake and the go pedal flat down at the lights. When it's green off the brake and it's like launch control on the old F1 cars ;)

How much energy goes into petrol then compared to how much energy you actually pour into the tank?

I have to admit I come with some pre formed opinions, cars for me are to get from A to B. I'm not interested in fast cars because I'm not selfish enough to pump me hard earned cash into one that will out perform a bike. I read the earlier posts by Brettus and I'm genuinely fascinated.

I pay little day to day attention to the motoring press and it didn't seem so long ago that electric cars were hopeless, not so now it seems.

Hydrogen cars, well watch this space, but in the Cafe today I read this in the News of the World. OK not the motoring bible but well, the Car (another Nissan) looks good. It'll take a few years but Oil and Petrol will be history and of course Nostalgia is not what it was.

Take a look, a step in the right direction I think. (Apart for the name which reminds of a urinary passage)

I've just had a bit of a google and found someone calculating around 7.3kwh per UK gallon of petrol. If I get some spare time I'd like to work out how much "electric" you put into your tank every time you fill up, how much you use per mile etc and how it compares to just fueling up with electricity alone.

And Damnit NTECUK, I'd have given that a try if I'd have known :D would have been funny to see the guys face!

I'm sure when the first ICE cars came along most people couldn't afford them, called them stupid as they couldn't go as far as a horse without finding this rare liquid to power it etc, history repeating itself?

I'm really interested to see how the various technologies progress in this area. My guess is that either battery production/charging technology will advance to the point where the disadvantages dissappear or alternatively the logistics of hydrogen delivery are made easy and safe enough to enable it to become more widespread.

There are a couple of interesting solutions with battery charging under development, the 'splash pad' is a new capability that is being used for smaller batteries on devices like mobile phones that let you charge by placing the device on a suitable surface, no reason why this couldnt be developed on a larger scale and built into the road surface allowing you to charge your car as you drive. The other is instant charging, a new technology that enables near instant re-charge of a battery.

The big question I have though that has largely been ignored so far is the tax that is currently gathered from fuel purchase. What will replace it? It has to come from somewhere and my guess is that it will be absorbed by the motoring public as some form of increased road tax. If that is the case then it begins to remove the financial benefits of these new technologies, you'll benefit in the short term but only as an early/mid term adopter.

Sadly that is going to be the case, you pay extra to get these cars to start with and then later on the tax gets shifted across to EVs/Hydrogen cars or whatever turns out to be the next alternative with longevity as they become the majority. As you say the money has to come from somewhere though so hey ho.

I'd still like an electric SV, 50 mile range would be enough for my commuting, again not as a replacement for my current SV, just to suffice for the commute and regular short mileage trips.

but then it wouldnt be an SV would it?

in the future are we going to be comparing number of battery cells instead of cylinders? ;-) "dude, I love the slightly higher pitched whistling sound of your 8 cell!"

No admittedly it wouldn't be an SV anymore, which is a shame, its just I have a curvy sat there and a hankering for electric vehicles now :D

and that is a scary thought about the number of cells hehe. People would have mp3 players with vtwin noises and a bigass speaker disguised as an exhaust ;)

And when you plug in the new soundtrack the throttle response changes appropriately. So the cool practical joke is to plug a 125cc vespa soundtrack into your mates new 32-cell Harley. :)


(Note: The new 32-cell harley weighs twice as much and has half the power of a regular bike because they're still using lead-acid batteries!!)

Charging a mobile one thing . You should look at the size of our fast charge point . Its a big as a large vending machine , it has 3 cooling fans that go pretty flat out. Our demo leaf is generally slow charged it's better for longer batty life .
