Perhaps the end of kit car making as we know it?
David Jenkins - 15/11/20 at 09:51 AM

BBC link

I'm guessing that registering a petrol kit car will not be allowed when they ban the sale of petrol & diesel cars. I would also guess that it will become very difficult and/or expensive to find liquid fuel in the future, as garages become more and more scarce.

It is possible now to put batteries and an electric drive train into a kit car - but currently it is incredibly expensive and, to be honest, incredibly dangerous for anyone who isn't savvy with high-voltage cabling (350 - 400V usually, with huge current available). Just for the hell of it I worked out how much it would cost to convert my Locost but lost interest when the total went past £10K, and that would be using second-hand batteries.

As I am already the driver of an electric car (Kia e-Niro) I shall now duck down behind the parapet and await the outrage...

I might be completely of track, but weren't Westfield looking into a electric 7 awhile ago?

I know they've designed a electric shuttle car as I've seen that one

Search YouTube or Google for the megawatt.

Drag car thats battery powered,stupidly fast, but a range of just over 20miles iirc

Have you seen how much nitro-methane a top-fuel dragster uses on a quarter-mile run?!

It was put together by a company that was the subject of a TV series a little while ago. I can't remember what the cost was, but I'm sure it wasn't cheap. During the test drive he said it went like stink and had a range of around 100 miles. I could live with that.

The owner of Westfield took possession at the end of the show - what a miserable bugger he was too!

CORRECTION: They converted a Chesil Porsche Speedster replica, who are now owned by Westfield. I recall seeing some dreadful welding on the rear frame...

NoAlternator - 15/11/20 at 12:26 PM

In ten years time there should be components from scrapped teslas or leafs (leaves?) going a bit cheaper, surely that'd reduce the cost of an electric 7? When they did the SVA -> IVA thing wasn't there a grace period for vehicles already under construction, hopefully they'll do something like that again.


Deckman001 - 15/11/20 at 01:00 PM

While i was at my initial IVA test a month or so ago, there was just two kit cars there being tested, but on the other side of the forecourt, there were over 15 Toyota Prius's being tested, used cars had been imported from somewhere and re-registered for use on our roads. I guess electric cars are the future although aren't some diesel cars being driven on crop based oils now ? With these crops being natural and regrown each year so reusable, isn't that another option ?

I saw that tv show, changing out the engine, gearbox, suspension and interior isn't a straight forward option.


taylormade100 - 15/11/20 at 01:29 PM

There was a tv show called vintage voltage that electrified a chesil speedster.

That's the programme I was talking about.


David Jenkins - 15/11/20 at 02:30 PM

I would really like to drive an electric 7-style car. My 1.85 tonne Kia e-Niro can do 0 - 60 in 7.5 seconds, which is not trivial for a big fat family saloon. I think the trouble with a Locost would be keeping the wheels from spinning - the torque at zero revs is mighty!

There would be a weight penalty of course, but I worked out that removing the engine, gearbox and fuel tank would mean that I'd end up 75Kg heavier once the electrics went in. The torque and smooth acceleration would more than compensate for that.

All a pipe dream though, as I could never afford it... and I'd be more than a bit scared of the electrics, even though I've spent a large part of my life dealing with electrical stuff in one way or another. Each block of batteries has hundreds of volts live and ready to bite you if you make a mistake, and you have to wire several of them together in a car, then wire them to the battery management module, motor and charging socket. At least internal combustion components don't bite straight out of the box! (well, the 12v battery might, if you're REALLY careless).


Mr Whippy - 15/11/20 at 02:49 PM

Don't know what the panic is about, 10 years from now it will be more expensive to fit an engine in a car than a motor and there will be masses of second hand EVs to donate their components. Yeah the tech is different but that's all, it's just different not anymore complicated. If anything life's going to be easier as many of the manufacturers are going for rolling platforms with Interchangeable body shells like the VW ID, just like the old days of vw beetle based kits. If I still have a 7 style car in 10 years I'd be quite keen on converting it to electric.

Soon all sports cars will be electric as their performance can't be beaten, ferrari and lamborghini already know this as even now their getting a hiding from Tesla and the like. Before you know it engine power will look as antiquated as steam.

Around the time I built my Indy I am positive mk built a chassis / car for someone in Germany Who made it a electric powered car it is / was on utube

That was about 2004

Dingz - 15/11/20 at 03:31 PM

At Stoneleigh 2017 there was an electric 7, I have a picture of it which I can't load, SQL error, looks like it might be milk float tech. but by a company Trident engineering.


perksy - 15/11/20 at 04:31 PM

I seem to remember a single seater hillclimb car being designed with an electric motor driving each wheel
Not sure it ever got built though..


ettore bugatti - 15/11/20 at 04:33 PM

There are ton of options available to convert kit cars to electric, being helped that there are a few companies focussing on converting classic cars.

Eco classics did convert a Westfield Eleven, which equals/ slightly betters 1275 A-series
https://www.ecoclassics.co.uk/lotus-xi-replica-electrification

And Swindon Powertrain has a kit that fit the classic Mini subframe
https://swindonpowertrain.com/documents/Classic_Mini_Kit.pdf

I dont think the motor, controller and charger for electric propulsion is the biggest challenge, it is more about getting the batteries right.

You will need pretty much all the time a custom designed pack that fit in the space available and with a battery management systems. The engineering costs and cost for cells will be a big chunk of the total cost.

Another point ot touch on is legisation, looks like battery packs over 48V (and for good performance you will need high voltage) need to be ECE R100 homologated which adds costs and is only really viable for volume production.
Although Hyperdrive repackage Nissan Leaf Modules in 44V that are can be used modular.
https://hyperdriveinnovation.com/battery-energy-storage/

So like said before when you add everything together you soon looking at £10-20k costs for a system that performs adequate, but then have a look what a GM E-rod crate engine costs and that might convert us to V8 power.

I think you're right - legislation around vehicle batteries will be a big hurdle, probably.

We'll see...


harmchar - 15/11/20 at 05:43 PM

I am hoping that hydrogen technology gets stronger infrastructure as it would be more realistic for people that travel further than the current crop of battery powered cars can do. I look at the range on offer of cars below £30k and most of them are pathetic. Just not a viable option just now. They are getting better, but who wants to be sitting in a service station for an hour for batteries to charge?
Hopefully the demise of petrol will be another deadline that will be extended as the time gets closer and the powers that be realise the infrastructure is not there to support mass changeover to batteries.

Anyone tried to weld a hydrogen tank in a 7 yet


harmchar - 15/11/20 at 05:48 PM

A YouTube vid of a guy converting an MX5 to ev. Looks like a lot of stuff to squeeze into a small space but must be doable.


Simon - 15/11/20 at 06:18 PM

https://www.electricclassiccars.co.uk/ do electric conversions on classics.

The chap I collected my gearbox from was putting a Tesla motor into his Boxster - he had a spare but wanted £3k for it. Sadly the batteries etc would cost upwards another £10k.

I'd love to build electric for the torque delivery and general performance but lack of range, cost and let's face it they don't sound that good

Considering that petrol has more energy than TNT and we're still allowed to put the tank behind the axle I'd say batteries are a lot safer. Besides there are new batteries that you can crush and cut without catching fire these will become the norm. The whole idea of filling your car with many liters of explosive chemicals will soon seem utter madness.


David Jenkins - 15/11/20 at 06:34 PM

Imagine if the internal combustion engine had never been invented - I often wonder what sort of reaction there would be if someone tried to introduce petrol-engined cars as a new thing these days!

"What?! You want to put 50 litres of petrol in a metal box and strap it under a passenger-carrying vehicle that will travel at 70mph? With loads of other vehicles around you? Giving off all sorts of nasty fumes as it goes along? No way!"

Don’t panic, the infrastructure to charge electric cars is not in place, this is propaganda piece because we are hosting the world climate change conference next year.
It is a little known fact that the power limit in most houses is only just up to the job as it stands, if every house in the UK had to charge a huge electric car power pack overnight the cables in the roads would melt ( at t to he same time your houses burst in to flames) and the national grid would collapse.
Now extrapolate the increase in world electrical use and in a few hundred years the earth will glow red because all that electrical power has to ground to earth

Sorry but that's just wrong. Home charging points work at 220-240 volts, typically at either 16-amps or 32-amps. A 16-amp charging point will typically charge an electric car from flat to full in around six hours.

My house has electric heating, electric cookers, showers, washing machine, dryer all of which I can run at the same time and not blow my house up. Even the fastest home charging is only about 15% the rating of an average house. Just converting your home to LED lights is enough of a saving to charge your car.


David Jenkins - 15/11/20 at 09:59 PM

As he said - quite a few experts have stood up and said that the infrastructure isn't a problem. It will need managing, but it will cope.

What really does sound interesting is the proposal to put the cars' storage capacity on the grid; the technology already exists to use a car's battery in the same way as a Tesla battery (but not in the UK yet - soon though), but the idea is for all cars to store surplus energy to feed back into the grid in periods of high demand. Presumably there will be incentives to do this, otherwise most owners will give 2 fingers! Nice idea, but not sure of the practicality.

The only thing I had to do to my house was to get the main distribution fuse changed from the old 40A to the current standard of 100A, and the 'tails' that go to the meter changed to a greater thickness. Neither job cost me anything. I'm surprised the old fuse didn't blow, considering the stuff I use in the house, without considering the charger!


BenB - 15/11/20 at 10:25 PM

40 amp main fuse? That's mean! I didn't know that was even a thing. My supply is from about 1920 and is 100a!


peter030371 - 15/11/20 at 10:31 PM

They are on about banning NEW IC powered vehicles not petrol... For a few years taking a pre IC banned car and rebuilding it into a kit car might be a boon to the industry. Fuel will be available for decades, up until 2018 my local specialist garage still sold 4* complete with full fat lead.

I bet we can still build and run IC engines under a classic car scheme for another 30 years. I'll be to old to drive by then.

I'm more worried about banning human drivers than how we power our cars


Irony - 15/11/20 at 10:58 PM

16amp socket charges a Tesla to the tune of 18 miles in 8 hours. I know as every time I call a engineer out at work. He arrives at 9 and leaves at 5. He always, always comments at my measly 16amp socket charging his car only 18 miles. Then he sends me a invoice for £600 a day.


Theshed - 16/11/20 at 08:53 AM

I cycle to work. When I am coming home in the evenings the pizza delivery boys blast past me on converted electric biles with about three extra batteries strapped to the cross bar. They do not even pretend to pedal. Which has got me thinking...about a 7 style car with 4 driven wheels from electric bikes. If kept really light (say sub 300kg) it should be as fast as an electric bike which for around town is fast enough (says a man with a spreading conviction for doing 24mph!)

Four of these perhaps?

just a pipe dream to keep me going as I pedal uphill

Strikes me that with narrow wheels it might be a welcome move back to the Chapman ideal of low weight etc.

My 'granny charger' plugs into a domestic socket - that will give me a charging rate of about 3KWh. It works out to an input power of 15A, so you have to be very confident in your socket writing back to the consumer unit! That equates to roughly 20 hours from empty to fully charged.

My proper domestic charger gives 7.2KWh and takes 35A, so that has its own feed from the consumer unit. That will give a full charge in 6 - 7 hours. However, I rarely let it discharge that far (I've only reached minimum charge once in 3 years). Normally I'm just charging from 40 or 50% up to 80%.

Teslas run about 3 miles per kwh. Your guy is yanking your crank. Or you're mis-hearing him and he's saying 80, which is pretty close to the real number.

By the time this proposed nonsense comes around, self driving car technology will almost certainly be better than the average driver and maybe all drivers. A lot of big companies are throwling a poo load of money at this.

I don't like it and am very much a luddite, I won't have an automatic gearbox as I want to decide when to change gear, LOL.

I'll miss the noise, smell and fire of the ICE but mostly likely by then I will be sitting on a wee soaked seat on mobility scooter at the care home.

Yes, Batteries take almost half of that budget. You could run a Chevy LS v8 on that budgety for a few years on race gas

With regards to battery legisation:
quote:
The ECE R100 approval process involved a first test by KBA concerning the compliance of quality and production systems, followed by the examination of the characteristics required for the manufacture of lithium batteries for electric vehicles.

After successfully completing the first phase, the second required safety testing to subject lithium batteries to the main stresses found during their use with vehicles:

Vibration test, 3 hours with variable frequency between 7 and 50Hz
Acceleration test, to simulate the deceleration in case of impact, up to 28G longitudinal and 15G transverse
Crushing test, 100kN = 10 tons laterally
Thermal stress test, from + 60 ° C to – 40 ° C
Fire resistance test, battery exposed to direct flame for 70 seconds reaching 700 ° C
Short circuit test
Test at maximum temperature, operation at 60 ° C
Test of internal security, overload test and over-text
Compliance with electrical safety



So quite a few destructive tests in there.

Not worried about the tech, it will be safer than humans. But I enjoy driving and fear the day we are not allowed to drive. By then who cares how the auto-car is powered.


JC - 17/11/20 at 07:08 AM

There is a big difference between an aircraft autopilot and a self driving car. An autopilot responds to simple commands and has limited, if any ability to react to its environment. In fact it is constantly receiving inputs from the pilots. Even so called drones are the same and largely reliant on ground station input. Trials are just beginning on fully autonomous ‘sense and avoid’ versions.

My Kia has a range of so called driver aids. Frankly, most are terrible! Lane assist: Works ok. As long as the road is well marked and dry. It doesn’t detect the white lines in damp or wet conditions and many Lincolnshire roads don’t have them. auto emergency brake: triggers when a car is turning left in front of you and is clear of your carriageway. Didn’t stop me rear-ending a woman who randomly stopped at a junction on a clear road having already set off! Distance cruise control. It’s great. Until it isn’t! If someone intrudes on the gap between you and the car in front and there is any sort of closure speed, it jams on the breaks. It’s only a matter of time before I collect someone in the rear.

Yes, these are 2019 Tech and there is a long way to go but my fear is that autonomous cars will introduced before they are fully ready. The boss of thatcham has already warned of this and the dangers of the semi-autonomous cars that are the stepping stone.


ettore bugatti - 17/11/20 at 12:32 PM

As stated, plane autopilots are a different beast and the level of risk acceptable with a plane full of 300 people vs an average of 2 car occupants means the risk vs reward tradeoff is very different. Plus, of course, there's only a handful of plane autopilot manufacturers and fewer that are large enough to do it, vs quite a few very well equipped auto manufacturers and their supply chain.

I can see the safety side of this being forced through and people being taken out of the chain sooner than we expect. Governments and industry are trying to push the "oh you will be able to relax and be driven, it's a luxury" side of them. And that's because lots of people hate driving and see it as a chore, or at best see it as a necessary inconvenience. Those of us who enjoy driving will become the minority and naturally, as our minority view is likely to be seen as less progressive and less safe, we will be removed from the equation.


craig1410 - 18/11/20 at 11:26 AM

Hi all,

Just to add my tuppence worth to the discussion on self driving cars...

Speaking as a software engineer, electronics engineer and petrol head, I strongly believe we'll be waiting a very long time (several decades at least) before cars are fully autonomous. Yes, we have some driver aids already plus Elon Musk would have us believe that full autonomy is just around the corner. Absolute nonsense though!

What is "around the corner" is a driving scenario that even the most advanced autonomous driving systems (not Tesla btw) aren't equipped to handle whereas a human driver would handle such a situation pretty well. Where humans tend to fall down is in areas such as tiredness, inattention and not taking account of road and weather conditions and those are certainly areas where autonomy has a role to play. (eg. detecting someone falling asleep and automatically pulling the vehicle over safely)

Coming back to Tesla/Musk, don't you find it interesting that it is easier to land two spent rocket stages simultaneously than it is to create a fully autonomous vehicle?

It's not rocket science....it's much harder than that!


coyoteboy - 18/11/20 at 11:21 PM

Landing two rocket engines is a slightly more advanced inverted pendulum problem, genuinely baffling it took so long.

I don't believe it's as far away as you feel, but I will agree to disagree.


nick205 - 19/11/20 at 09:10 AM

Autonomous cars?

My personal view here BTW

Personally I can't see the point in getting more cars onto overcrowded roads, especially empty cars. So many cars only have one person in them already it's laughable. I'm not a motorcyclist, but if we're really just trying to move single people around motorcycles do seem a better option. I'm sure if the manufacturer's put their minds to it we'd have motorcycles with better weather protection for damper colder climates.

For those that may have seen a Renault Twizy, I don't mean that. IMHO that didn't take off sales wise, because it didn't actually provide any proper answers. IIRC they were expensive as well.

Could kit building going over to cycle-car type vehicles? Morgan trike-like with a single powered rear wheel?


nick205 - 19/11/20 at 09:46 AM

Thinking further...

Encouraging employers to provide staff changing rooms and showers on-site would be another step forward. Before we moved premises we had a changing room and shower at work. It made cycling to work feasible. Yes you got there hot and sweaty, but a shower and fresh set of clothes soon sorted that and you're VERY wide awake for the day ahead.

Again, my personal views...

Help humans change their behaviour!


steve m - 19/11/20 at 10:51 AM

I believe that public transport should be an awful lot cheaper, and more reliable
My Daughter in law spends 10k a year to get to and from work on trains to London, and that represents 20% of her earnings just to get to work ?
Well it did, as she works from home this year, and has saved a shed load!

My take on Electric cars, is that Hybrids are the way forward, Petrol /Electric seem to be the best option, although the Prius is possibly the worst car ive ever ever driven! and as ive said before, i "used to work delivering brand new cars" the only fully electric car ive driven many times, is the Nissan leaf, and thankfully the longest drive i had to do was around 100 miles, just as well, as at motorway speeds it wouldnt of done many more,
I believe the figures say 160-180 mile range, but ive never experienced any thing close to those figures

Imho electric vehicles need to have a minimum range of at least 250 miles before being introduced on our roads in 2030

steve


David Jenkins - 19/11/20 at 11:43 AM

The Nissan Leaf is not a good example - it's mileage estimates are rubbish, they lose miles rapidly if you go fast, and there are problems with repeated fast charging (a.k.a. RapidGate) . My e-Niro has a quoted range of 285 miles, but with constant 70 mph motorway driving with heating on, in rain and wind, that drops to 225 miles roughly. If I am going cross-country at the usual 50 - 60mph (which most people average, whatever car) in summer I can achieve somewhere around 300 miles (I have done this).

A very well-known YouTuber's recent video shows him driving a Kia e-Niro from Canterbury to Lands End, then on the John O'Groats, then back to Canterbury - in one weekend. He was driving most of the time at normal speeds for whatever road he was on. Recharging as he went, of course, plus an overnight stop, but it was a hell of an achievement.

Another group of people have got over 600 miles from an e-Niro like this - but that was at 25 - 30 mph constant, with all accessories off. On a test track, of course!

The nearest equivalent to a petrol/diesel car is the hydrogen fuel cell vehicle. Unfortunately there are very few cars available, and none in this country. Also there are hardly any hydrogen stations in the UK. They've got a long way to go yet...

I'm sure if the manufacturer's put their minds to it we'd have motorcycles with better weather protection for damper colder climates.

For those that may have seen a Renault Twizy, I don't mean that. IMHO that didn't take off sales wise, because it didn't actually provide any proper answers. IIRC they were expensive as well.


Nah not IMO, motorcycles have 33x the fatality rate of cars because of a host of reasons, not least the lack of protection. Sure most of the time I move one person with my car, but most days I move one person, then pick up another and go somewhere. Most weekends I fill it with stuff to go do sports. Given how much cheaper motorbikes are both on fuel and purchasing, if there was any real user base it would be expending rapidly already due to austerity and easy availability of moped/scooter types.

Self driving cars will not be owned by people, it'll just be a rented fleet like taxis - you'll hail one when you want one, not own it and have it sat on your drive, and at that stage they'll start to ban human drivers because of their increased risk. That in turn will simplify the autonomy process. It's certainly not progressing as fast as I expected back when I was doing robotics research, but it's ramping up now and there's some very big companies with very deep pockets looking to generate the next disruptive technology. As these things become closer to reality, governments will start to adapt infrastructure to help them become reality.

I've got to disagree with the notion of hybrids being the way forward. They combine the complexity of both internal combustion and an electric powertrain while being neither a good IC vehicle nor a good BEV vehicle. It's a compromise plain and simple. The only reason they are popular is because Toyota have done a damned good job of their hybrid platform at a time when a full BEV was technically difficult. That time has now passed.

However, with EV ranges now exceeding 200 miles and charging infrastructure improving, it is fast approaching the point where there is no perceivable downside to EV ownership. We've owned a BMW i3 since January 2017 and my wife commutes around 60 miles a day in it an absolutely loves it. Granted, our i3 only has a range of around 120 miles as it's a 2017 model but that is almost never a problem and we have the 535d as our long range cruiser. I realise, not everyone can justify two cars but for those who can, a separate BEV and Petrol/Diesel car are a far better option than a hybrid. We mostly charge the i3 at home but our electricity provider Octopus have a tariff where you get electricity at 5p/kWh for 4 hours each night. That's more than enough time to charge the car each day and results in a full charge for less than £1.50. That's something like 1.25p/mile!

Then there is servicing, which for the i3 is very cheap since you only need to change brake fluid and cabin air filters every couple of years. No oil/filter changes, spark plugs, fuel filters, engine air filters, belts, water pumps, coolant, thermostats and even the braking systems last forever due to regenerative braking. The i3 is made of aluminium, plastic and carbon fibre so rust isn't a problem either. It does tend to chew through tyres quite quickly but that's mainly due to the 170 BHP and the fun factor of zooming around.

I know that things have moved on a lot since we bought our i3 and in many ways there are better cars available out there depending on what you are looking for. The i3 certainly doesn't excel in terms of range but honestly I couldn't care less if some cars can do 300 miles on a charge because nobody should be driving 300 miles at a time without taking a 20-30 minute break during which time you can recharge. I personally love to just keep moving but I'm usually travelling with others who like to stretch their legs every couple of hours. Why carry the weight and cost of battery capacity you rarely need?

Lots of good EV options out there now and it'll only get better in the next decade. Nothing to fear IMHO and I would seriously consider converting my V8 Locost into an electric one if it didn't cost so much!

ok lets have a think about this .

lets look at a motorway service station , we will need to refuel more due to ltd endurance , so say i need to go from Manchester to London
for the foreseeable future that's at least 1 full recharge possibly 2 , south coast even more ,
so lets do some sums
it takes 40 mins to 1 hr to charge i believe

so lets say 1 car 1 hr charge ( maybe using super capacitors ) 100kwh
now times that by say 100 cars per hour probably fair , now that's 100,000 kwh per hr per motorway station
now that's some feed cable / substation infrastructure there to start with
feel free to correct my numbers ps: now add in commercial vehicle's who need what 800 kwh battery packs !

now lets look at home charging
each house has 1 to 2 electric cars ( this is a low average figure )
so they have to recharge over night say
now every one down your street has to do the same thing plus run Electric Heating / cooking !

so houses are loaded on the street supply now tacking into account not every one needs electric at the same time BUT " now they do"

so Ladies and Gentlemen and every one else , we now have world cup switching on the kettle at half time x a factor of 20 - 30 ?

so we have to rewire every street in the uk every substation and the grid , build probably 2 to 3 times as many power stations without green house emission's.

any one else here see a problem ?????

What if the motorway service station were to become a thing of the past? What if charge points were distributed along the length of the motorways and trunk routes? Or if travellers were encouraged to venture into local villages and towns to spend their cash instead of funnelling it all through the large services companies? Would that be so bad?

What if people have Solar PV at home with a battery pack (recycled vehicle battery pack) and it gathers solar energy all day ready to charge your car back up when you plug in at night with no load on the grid? What if people charge their cars while at work instead of when at home?

I have no doubt that energy management will become important as more and more people move to EVs but it doesn't have to happen overnight so there is plenty of time for the network to adapt to the needs of the consumers. The World Cup kettle analogy falls down in that not everyone needs to charge at the exact same time.

The simple truth is that, if you need to burn fossil fuels then it's more efficient to burn them in a constant RPM large generator than in millions of individual vehicles. Combine that with renewables and some nuclear and we will have more than enough electrical power to get the job done. Yes, distribution networks will need some upgrades but that's been the case for many years and will happen.


SteveWalker - 20/11/20 at 12:52 AM

The trouble is that electric cars cannot do some things that petrol ones can. For instance, one Friday night, I arrived home from work at the same time as my wife found an answerphone message that a relative had died and was being buried the next day. We were too late to get a plane that night and the earliest in the morning would be too late to get us there. We had a couple of hours to get ready and get the kids to my parents, before we drove from Manchester to Holyhead; Onto the ferry; From Dun Loaghaire to Sligo, arriving 15 minutes before the funeral. We attended the mass, drove to the graveyard for the burial, then to a hotel for the reception. Stayed about an hour, drove to Belfast, ferry to Cairnryan, back to Manchester and picked the kids up. Almost 24 hours start to finish, 5 to 10 minute stops for petrol, toilet and driver change only.

Another time, after driving home from another part of the country, a friend phoned asking to be driven from Manchester to Nottingham - his mother had just died, he did not feel safe to drive, but he needed to get there quickly - a sudden, unplanned for journey, immediately after another long journey.

If electric cars switch to standardised, replaceable battery packs (maybe one for small, short distance town cars), one (or more when required) for longer distance, larger vehicles. Each manufacturer to detail location, angle of movement, etc. to remove and insert and stations that can swap the batteries in minutes, using robot arms - then they will be a suitable replacement.


craig1410 - 20/11/20 at 01:05 AM

There will always be exceptions, and solutions will emerge to deal with them. I know this wouldn't have helped in your case but BMW already have a scheme for EV drivers where you can hire a petrol/diesel car at good rates for those times when an EV isn't appropriate. I'm sure in future it'll be possible to drive into a facility in your EV and drive out in a diesel. Or perhaps just drive the EV onto a train like on the channel tunnel and then drive off at the other end. Lots of possibilities which are probably preferable to driving non stop for 24 hours.

I've always wanted a Land Rover Defender fully kitted out with snorkel and extra fuel tanks and camping gear etc for when the zombie apocalypse (or next pandemic...) happens but until 2020 happened I didn't think I could justify it! Maybe time for a rethink!

I'm on Octopus Agile - the price of electricity varies every 30 minutes, according to the market price. It generally averages around 10p - 11p per KWh, which is cheaper than the usual fixed rate but it can go way below that at off-peak times, even down to a negative price. The only down-side on this tariff is that you get hammered at the peak consumption period between 16:00 and 19:00 every evening (around 28 - 30p per KWh). This wouldn't suit some people, but as there are only 2 of us in the house, and a lot of the time we cook on the gas hob anyway, this is a penalty we can cope with. We make sure to never charge the car, run the tumble drier, etc during this period. Of course, this is exactly what the electricity company is trying to encourage - levelling the load on the grid.

The result of this is that on sunny days I often charge the car during 'normal-to-low rate' times so that our solar panels take some of the load - on good days I'm only taking 4KWh off the grid, with solar providing the other 3.2KWh. And I'm getting paid for that 3.2KWh...

I believe that everybody's electricity use is going to change in the near future as many companies have seen how popular Octopus Agile has become - there are at least 2 other companies with similar schemes starting up quite soon.

Quick and shameless plug: if anyone wants to change to Octopus please get in touch with me - I can give you a referral code that would mean a significant chunk of money off each of our bills!

The specific hours vary by customer - for me they are between 00:30 and 04:30 but for other members of the same tariff it varies.


David Jenkins - 20/11/20 at 12:45 PM

Purely a coincidence, but I've just seen a picture on the Kia e-Niro facebook group that shows a car's display after a charge: 278 miles predicted range, 58295 miles on the odometer. 278 miles is pretty damn close to the 285 miles predicted by Kia. This driver uses a mixture of home (slow) charging together with high-speed charging during his working day. Slightly skewed data as I believe that the owner is a cab/uber driver in London so he would rarely do sustained long-distance/high-speed driving, but it's still impressive. This shows that batteries are no longer as delicate as they used to be, although he has gone through quite a few tyres in that period!

Note: I know I keep blowing the trumpet for electric cars, but I am very realistic about them - mine handles 99% of my driving, and I can cope with the other 1%. My wife's family lives in and around Gloucester - I can easily drive there on one charge and still have a bit of charge to spare (although we normally stop at Milton Keynes for lunch and a top-up charge while eating). My brother lives in Dornock, Scotland and that's a 2-day journey from East Anglia, if I'm going to be sensible about driving long distances. I can get to Glasgow in 2 hops, charging while we have lunch plus probably one brief extra top-up (pee break!), and easily get to Dornock in one hop the next day, with 'half a tank' remaining. Both journeys would be at normal speeds, not reduced to get more range.

With my old 40KWh Nissan Leaf I'd be lucky to get 125 miles on a full charge at dual-carriageway/motorway speeds. I certainly couldn't even get to Gloucester without a significant charge at MK.


craig1410 - 20/11/20 at 12:51 PM

I really think there is a need for some sort of drive on, drive off train, ideally with charging capability onboard for the electric cars it is transporting. If that formed a "backbone" up and down, and perhaps across the wider parts of the country so that everyone can get to within say 150-200 miles of any part of the UK, then problem solved!

It costs a single person so much to get just a rail ticket across the country that I think it would be much cheaper to drive the electric car, even taking the expensive high-speed chargers into consideration. In fact, for my Scottish trip, you could include the cost of the overnight stay and still end up cheaper!

pigeondave - 20/11/20 at 04:21 PM

Like others have said about digging up the roads, we're not making provisions now on the new builds.

I'm unlucky enough* to have worked on some fairly large London regeneration projects, and for the number of units we're putting onto a site (think tower blocks) have only a handful of charging points allowed for. Admittedly I switch off when M& E start to talk because they ALWAYS cause trouble.

If this is the future, why is there not a provision for every parking spot to be EV ready ? doesn't need a cable to it or a charging point, just a way of making it easy to hook up when needed.


As for autopilot cars, this will happen and we'll have to lump it. They'll force you to do it by hiking up insurance or something else until only the very rich can afford to drive.




*I am lucky to be working, I know. But most days it doesn't seem fun.

Will many of us still be here in 2030 ? as with whats going on at the moment, a good percentage of us wont be!
Also, and im unemployed now since March, my annual mileage is about 1k and all local ,

Im sorry to say, but our elected govenment are f ing clowns, and should be rallying us all around to be positive , and look forward to our future and good covid free health, but oh no, the elected idiots have decided that one of their
incestuous sisters, who's a raciest and bully is innocent ??
they sack half the team that have been advising these idiots about covid ?
They invest billions of pounds to our military, money we dont have, so our kids and grandkids will be destitute
They have fucked up totally over Brexit

I am sorry, but i have no faith in these clowns ordering a cheese sandwich, let alone making a real decision that will affect ALL our lives,
This 2030 nonsense wont happen, and i doubt it will in 2040 the original dates banded about,

And then, just to make matters worse, we have a complete loon in America, with one finger hovering over "the red button"

Some years ago I was in a pub and happened to end up talking to the local candidate for the MRLP - he was actually very sensible, articulate and logical. To be fair a number of the MRLP's policies have made it onto the statute books - 24 hour licensing; lowering the voting age to 18; abolishing dog licenses; legalising commercial radio; passports for pets amongst them.

Tbh top of my list for things next year is to get an EV, nothing fancy, most likely an older Leaf. Even its 100 mile'ish range is way more than I need. I'm really looking forward to it, even being an old petrol head.

I've been in Tesla's at events, their just the stuff of dreams, well outside my price range for now, but if I won the lottery, feck the Ferrari I'll be in the Tesla showroom that same day

Been in a leaf at 30mph on grass, literally could not hear anything, it was just totally silent! Very weird.

No I'm not on the inside in any way but frankly I consider myself fiscally conservative and socially liberal which I guess in normal times aligns me pretty well with the likes of Cameron and to a slightly lesser extent Johnson. I also believe very much in the UK and one of the things that pains me most is how this pandemic has fractured the UK with all sorts of political agendas going on. I find that sad because the pandemic doesn't respect borders or political divides and should really have brought us together. It seemed to do just that back in March but by the time we got into the summer it all started to diverge. Different slogans, different number of tiers, different lockdown timing, different travel quarantine country lists, different track & trace apps etc etc.

Governments on all sides in all countries have made terrible mistakes but I honestly can't bring myself to undermine them or call them names because I am pretty sure I could not do a better job myself and honestly I don't think I would want the job because it is an utterly thankless task. The govt get criticised for moving too fast or too slow, for being too cautious or not cautious enough, for agreeing with one group of scientists against the advice of another, for trying to balance saving lives now vs saving livelihoods down the road, for restricting liberties too much or not restricting them enough. And there is no playbook for this to consult. Yes there have been pandemics before but you can't compare a post war pandemic in 1918 with Covid-19 in today's world where we all regularly fly around the globe for business or pleasure. Even the more recent SARS and MERS epidemics were not really comparable although the countries affected directly by those were probably better prepared for Covid.

So frankly I mostly give our politicians and scientists a pass because for the most part I do believe they are doing their best. They were elected democratically by us all collectively and the various top scientists and other civil servants rose to their senior positions either by merit or by the choices of previous and current elected governments. We won't really know how well each country and government did until maybe 5 years from now when we can look back with the benefit of hindsight and properly critique each key decision. In the meantime we should stop second guessing every single micro-decision that our government makes and let them get on with the job at hand. I say that from a completely non-political standpoint because I think whatever major political plans Boris Johnson had went out the window back in March.

Someone criticised the increase in defence spending but as a father of two kids who are both in the RAF, and as a citizen of a country which chose to leave the EU and has attracted provocation from Russia in recent years, I think it's a very good thing indeed for our country's security. Let's not forget that military spending will also create lots of jobs not just in the military but in industry as a whole.

Yes, Brexit is looming and as a remainer I approach it with trepidation but unlike my Scottish nationalist friends, I have come to accept the result of the Brexit referendum and I have no doubt the UK will prosper outside the EU. There will be bumps along the way but the UK has a lot to offer other countries and further trade deals will emerge.

Anyway, I've prattled on for too long already after saying that I would refrain from comment...

Rest assured I respect opinions which differ from my own and I hope my comments above don't cause offence to anyone. I certainly don't claim to have the answers any more than our country's leaders do.

As I said before, I love driving our i3. It's a totally different driving experience but in a good way! The smoothness and instant torque must be what it's like to drive a V12 with noise cancelling headphones on!

I used to have a 40KWh Leaf - OK in many respects, but poor in others. They increased the size of the battery from earlier models, but didn't uprate things like battery heat management. This meant that you couldn't do more than 2 fast recharges on a long fast run as the battery management system limited the charge rate to protect the battery. A well-known YouTuber had a 'race' from the south of England to the north of Scotland (he imported used electric vehicles to one of the Scottish islands). Although is 40KWh Leaf had the greater range, he was the last to arrive as his last few charges took so long. The others (Ioniq and an old Leaf, I believe) got there long before him because they could charge unrestricted as often as they liked, even though they had to stop more often.

So an earlier Leaf is not a bad choice - limited range (good enough for most drivers' normal driving) but otherwise very sound. You might also consider a Renault Zoe, especially if you're prepared to pay the rental for a leased battery - because many are put off by the battery lease the cars are often very cheap (around £5K) and the rental isn't that bad. Also, Renault replace the battery if it dies at no cost to the owner (I believe).


Mr Whippy - 21/11/20 at 10:10 AM

Thanks, the leaf would be used for very specific journeys, all quite short and highly predictable. We have a volvo for long trips and towing. The Renault Zoe is a cracking car but more expensive and the battery lease too expensive for its purpose, although for higher mileages it would be my first choice.

On the topic of hill climbs, Pike’s Peak at >14,000 feet is the ultimate test. An electric car took the record in 2018 and will continue to do so. Electric cars aren’t gasping for air at that altitude.


tomprescott - 20/1/22 at 08:22 AM

My two penneth: The speed of electric sports cars will be nuts but the lack of sound will mean fewer people think it's worth it to have the compromise of a small sports car. Given the electric motors can shift chunky cars relatively quickly (like Dave's Niro) I expect the future will be sport versions of 'compact SUVs'.

Regarding costs coming down for kit car builders in the future... Possibly. However, the biggest car seller in Europe (VW) have announced they are no longer planning on making cars to be sold to people for personal ownership, only making cars that people can rent/ pay as they use. If others follow suit then the chance to pick up cheap second hand cars might just disappear entirely!

The electric single-seater hillclimb car Perksy was thinking of was probably Martin Ogilvie's (ex-Lotus F1 Chief Designer, and responsible for the PCD Saxon and Graeme Wight's Raptor and Predator hillclimb single-seaters). It was never built, due to lack of funding, but was well ahead of its time - I've got some of the CAD drawings on my computer.

Never mind Pikes Peak; on the shorter UK hillclimb courses, electric now makes a lot of sense... you don't need big batteries for a 60-second run, so the combined weight of batteries, motor (much lighter than ICE) and transmission (again, much less than ICE) means that overall weight is perfectly competitive - potentially even lighter than an ICE car - you can achieve a lower centre of gravity, and you have the massive advantage (for hillclimbing) of instant torque, everywhere.

The Luddites might bemoan the lack of noise and the smell of polluting hydrocarbons (whilst the rest of society will be glad to be rid of both), but if you actually want to go faster up a hillclimb course, electric offers a whole new world of opportunities.

Drag car thats battery powered,stupidly fast, but a range of just over 20miles iirc


Have you seen how much nitro-methane a top-fuel dragster uses on a quarter-mile run?!


The mileage I quoted is driving it normally to the drag strip!
