Dunno. The Ioniq 5 is one of the best towers so maybe.

Whoosh. I should have used one of these 😉

Ioniq 6

Hmmm.

So behind the back wheel was styled by Porsche and between the wheels by Merc, but who did the front of the car?

Yes I thought it a cross between a Mercedes CLA and a Porsche.

Whilst we're waiting for that to come out there's another new model on the market:

until there is a step change in battery cost and/or achievable energy density.

Judging by my news feed that's coming, and fairly soon. That's why I'll hold off getting another; either the new bsttery tech will be cheaper, or it'll demolish used prices of current tech. People seem to be pretty obsessed with being able to drive 300 miles or more without a stop.

Dunno where you are getting your news from but if you are waiting for solid state batteries the opinion from an expert at the Battery Cells and Systems Expo I attended today is you'll be holding off until after 2030. Yes pilot scale solid state exists but getting it commercialised at scale is going to take many years.

Lots of it from phys.org, about developments in battery tech. Sure the stuff they report isn't going to be on the shelves next week, but the numbers of people solving long-standing problems for different battery chemistries seems quite high. Lithium-air, lithium-metal, lithium-sulphur etc not just solid state.

Nissan is opening a prototype solid state factory and is aiming for a car on sale by 2028.

Id quite like to jump on the hype train some point next year when my current car will be 8 years old and owe me nothing finance wise. I'm not a bad candidate for charging at home since have a driveway and garage but currently work involves driving some fairly long distances. I tend to be fairly regular at stopping for a piss break anyway so to be honest I don't see it affecting much there.

Just wish they weren't so expensive to purchase or lease, I don't get any fancy company car salary sacrifice tax hack schemes just a straight up 3k a year (fairly shite) allowance, taxable at 20%.

How are you reimbursed for using your car on business? If you get the HMRC rate of 45p per mile then if you use an EV with decent efficiency that’s a nice little earner. Combined with lower maintenance and zero vehicle excise duty might make the total cost of ownership more competitive for you.

Nowhere near 45p a mile, more like 21p but it might be less than that for those using an EV. All I can do is claim tax relief on the difference.

Our company policy states 15ppm and I believe it follows HMRC.

This is me, just had to “refresh” a euro 4 diesel to keep it another year until perhaps costs and availability calm down. With the news that gov.uk is failing big time on he 2050 climate target I feel very dirty, but not prepared to hit the family financially in the current climate. I don’t think they are doing anything much to promote green travel IMO. I will though take trains where I can.

Judging by my news feed that’s coming, and fairly soon.

Going from success in a lab to commercial/domestic scales is a HUGE step. There are technologies that have been "solved" for lab and small scale tech use 10 or 20 years ago that are still 10 years off for true volume production.

I suspect the early Solid State cars will be much like fuel cell, low volume for a few years then quietly shelved, i mean, we've had fuel cells for a decade and there were still only something like 75-100000 sold globally, and that's over 10 models and 5 or 6 manufacturers, 3 of whom have discontinued development.

Unless they can actually solve the current issues on a production line, turning out 5000 units a day. Each one of which is almost fit and forget/minimal servicing for several years.

I was at the same show - albeit for the Advanced Materials bit - I has a wander around the battery expo for interest 😃

I get to deal with the people writing the articles, trying to sell their "fully industrialised process".

"We built a production line that can make 5 units an hour, scrap rate is 20%. I think we're ready for the big time now."

If they are giving you a car allowance then there is no compulsion to give you the 45p (and iit would be taxed if they did).
They can set their own milage rate that can vary between fuel types/engine sizes etc.
If you are doing long trips and need to use motorway chargers 5ppm probably isnt going to cover it.

Fortunately I'm also aware of how these things get written 🙂

My comment is about the number of different groups of people doing it, not what they are actually saying.

Not to mention that business mileage rates should cover total ownership costs on a pro rata basis rather than just fuel; in my experience, (on our second leased EV now, but also run two IC cars in our household) costs are not very dissimilar between electric and IC for reasonably new, like for like vehicles. They aren’t cheap to own, they just happen to have cheap fuel (for now).

which is why he gets the £3k car allowance

You either get car allowance + "fuel cost" which would be the ~15ppm ICE or 5ppm EV

Or you get 45ppm tax free (up to your first 10000 miles) and nothing else which is meant to cover, proportionally, your running costs, depreciation etc.

Ah, fair enough, didn’t spot that bit. To be honest, the way that running costs are going, both figures are pretty derisory.

This is what Molgrips is referring to I assume. A battery that's very thermal efficient so can maintain a max charge rate for much longer than current batteries

CATL LAUNCHES CTP 3.0 BATTERY
– CATL released more details on its new module-less battery packs called Qilin, which are expected to be mass produced and come on the market in 2023.
– The VCTP (volumetric cell to pack) ratio is 72 %, which is the percentage of the total battery pack volume dedicated to the active material that actually stores energy (cells), leaving 28 % of the total volume to the passive material, responsible of assembling and protecting the cells. For comparison, the popular BYD Blade battery had an estimated VCTP ratio of 62,41 % when released.
– CATL will use multiple metal plates between the cells multiplying the heat transfer surface area by 4, making the TMS (Thermal Management System) very fast and efficient in heating or cooling the battery. This will not only enable to heat the battery in just 5 minutes when there are freezing temperatures, but also cool down the battery so it can be charged at a constant 4 C-rate and only take 10 minutes from 10 to 80 %.
– CATL claims that the NCM packs will enable a range of 1.000 km, probably in China Light-Duty Vehicle Test Cycle (CLTC), which is around 782 km in WLTP.
– Imagine an efficient electric car with a 60 kWh LFP battery that can be charged at a constant 240 kW rate, do you really need more battery capacity?

No, but with more energy-dense batteries you could have the same range with half the weight and cost, e.g. with a lithium sulphur battery.

whatgoesup - the Model 3 will take two bikes (with front wheels off) and two people, and all their stuff. There's a surprising amount of storage if you use the froot and bloot as well as the boot.

I think you'd get three people and their bikes in. Would be uncomfortable though.

Model Y is the same price as the 3, isn't it?

@flaperon / yep, they’re pretty much the same price now I believe. I just like the way the 3 looks (simple vanity).

Realistically two adults and their bikes on a towbar rack (or roof mounted - plan to have both) is what I want to be able to do.

The bigger challenge is probably me plus two nine year olds and their stuff - scooters, luggage, a tent and sleeping bags and etc. I know it won’t be as “easy” as a big estate but do-able is good enough. If I have to put a roof box on regularly it will get annoying really quickly - ideally the roof box is for 2-3 trips a year etc.

Saw my BiL at the weekend. He’s picked up an old C1 EV’ie and a really old fiat 126. He’s stripping the guts out of the EV’ie and transferring into the 126.

looks like an awesome little project and my 10yr old son is itching to help.

I’ve been driving an MG 5 EV for 3 months and had an Audi A6 estate for 4 years before. I’m looking forward to the fast charging capabilities of the I5 as the MG would only pull 50KW

charge speeds tend to be overlooked and its just (if not more) important as over all capacity, the Niro tops out at 75kW and only for the first 50ish percent of battery, its 50 after that. doubling that would make a massive difference when charging out and about.

Charging speed dependence in starting capacity is a significant factor in planning a trip. It drops off after 50% and even more after 75%. If you could rely on chargers not being broken or occupied you could plan to charge at a lower state, saving time, improving battery longevity and freeing up the charger sooner. The percentage of chargers showing on zap-map as unreliable is quite high, and depending where you are it can be a long way to the next one with a reasonable speed.

In optimum conditions the MG5 should go up to about 95kw until about 50%, then gradually fall from there.

A problem is that "optimum conditions" are so rarely met that the claimed charging speeds of cars are worse than broadband speeds... it takes a warm battery (normally a good chunk of fast driving beforehand on a warm day), a mostly empty battery, and a charger that can actually provide what the car can take... most chargers are still 50kw ones anyway.

How are you getting on?

4 months in on AWD version and it's a great car. Looks amazing (IMHO), V spacious front and back, comfortable riding and seats on our rubbish local roads, fastest thing I've ever owned, handles pretty decently (with one proviso below), charges really quickly on the odd occasion I've needed to away from home, to the point where you only have time for a wee and it's back to 80%. Regen tech is quite complex but v configurable and clever. Loving not having to pod out for diesel - just wish I had the cash for solar panels. OTA updates now started for infotainment. Apple carplay is great but I also like the onboard sat nav.

Downsides are the boot is quite big but rake of the back window stops you piling it up. This is better if you remove the false floor. Massive with seats down eg for a bike.
If you drive it as per performance or fast on motorways the economy drops fast (same as IC!).
Loads of the infotainment is configurable but not the main driver screen that shows speed where there's lots of unnecessary visible space taken up with power/regen graphics.
When really pushing on round a corner that has undulations/potholes the traction/stability throws a bit of a wobble and you almost feel the rear hop. Strangely not mentioned in any reviews but it's definitely the electronics being over sensitive rather than the inherent chassis as it's not there when those systems are switched off. (whats the insurance situation if you spin it backwards through a hedge after turning safety systems off?!)
Charging speed is both charger power output and car-battery temperature dependent. So I have seen 220kw this summer (so quick the atmosphere is buzzing!), but often a 350kw charger only gets me 120-170kw. TBH that's fine and I'm coming to the conclusion anything 100 or more is the golden ticket for a trip top-up, to get you home. Mine doesn't have battery heating so this may be more of an issue in the winter but equally I've read people in Canada with battery heating, aren't seeing much benefit as the software isn't configured to help much.

All in a cracking car...and doesn't look like a wide mouth frog!

I thought some modern systems use some of the power from the charger to warm or cool they battery anyway?

Teslas preheat the battery as you approach a supercharger. The I5 doesn’t have that yet but it is a rumoured software upgrade in the pipeline.

Almost everything mid range or above on sale now does. If you've got smart mapping the car will start conditioning the battery for charging over the last ~10 minutes as you approach the charging location as well.
Overnight/home charging strategy on everything I've played with in the last 12-18 months starts by conditioning the battery to get to optimum (not fastest) speed as soon as possible. Then finishes off by conditioning the battery to its ready to drive state once it's at target SoC. (If you've set a departure time that is.)

Regarding batteries, Volkswagen have been involved with an organisation called QuantumScape who’ve been developing a solid-state Lithium metal battery, and they seem to have cracked the issues with dendrites growing on the cathode.

I'm going to Aviemore from Cardiff in September, debating wether or not to take the EV. It's 513 miles. Assuming 4.6m/kWh and 55mpg, assuming a full battery leaving home and 45p/kWh on-road charging versus £1.85/l for diesel that makes it £86 vs £154 round trip. I'd arrive in Aviemore almost empty so I could perhaps save some money by slow charging it when I'm there. I'm assuming the use of Gridserve chargers but some of the ones on this list are Charge Place Scotland which appear to be a fair bit cheaper.

However, I can only do it in Zap Map by setting the minimum battery to 15% and the max to 90%, because I'd need enough to get from Dunblane/Stirling ish where the last rapid chargers seem to be to Aviemore on one charge. The car can only charge at 50kW max, the quoted 20-80% time is 45 mins, and I'd need three stops. I might end up spending 3hrs stopped, which turns 8hrs of driving into an 11hr day. Not to mention the risk that chargers aren't working or are busy.

But, if I were driving diesel I'd still stop, probably for 1.5-2hrs total to eat and pee. So it might end up being only an 1-1.5hrs slower. That said, in the diesel I might be tempted to exceed the speed limit a bit on the empty sections of the A74M which could save a bit of time. I'd not dare do that in the EV.

The diesel is a much nicer car to drive all day in and a lot bigger for putting camping gear in but that's a reasonable chunk of cash saved and the time difference isn't that great when you consider the stops that humans need rather than just the car.

@molgrips - there are Ionity and BP Pulse chargers at Perth and Tesla chargers on the pilot in Aviemore.
There are free 40kw chargers in Perth at Broxden and South Inch and Dunkeld.
Some charge place Scotland places are free - make sure you sign up for an account beforehand and get the card.
Have a look at A Better Route Planner as an alternative / accompanyment to ZapMap

https://abetterrouteplanner.com/

edit - are you camping at Glenmore?

Thanks for the link OTS - once I readjusted the very conservative default settings it's given me 4 stops but each one is shorter so the total time comes down to 10h37 mins.

There are 5 options in and around Aviemore. Glenmore is my first choice because of access to the loch and bike trails. Not cheap, but location can't be beaten IMHO.
