A combined cycle gas turbine electric plant will be closer to 60% at peak efficiency at 55-57% average around the world.
48.3% in the UK so why aren't we investing more money in bringing the efficiency of our gas powered generation into line with the rest of the world?
You also have some gas generators that don't have the secondary heat exchange phase, plus there are specially built 'diesel farms' which are used when extra capacity is required.
Thing is, if we don’t transition to EVs then we will never have decarbonised personal transport.
100% agree but I'm questioning whether we should be more aggressive on the 2050 date. For example, the biomass generator at Drax generates 11% of the UK's 'renewable' power and gets £832m a year from the government in subsidies but still pumped out 13-16 million tonnes of CO2 emissions in 2019 - equivalent to the emissions from 6-7 million cars and is the largest CO2 producer in the UK.
I did two big trips Yorkshire to Fort Augustus last year without issue. I didn't bother with the Tesla superchargers in England because Tebay and Gretna had previously always been rammed. So just stuck to the other charger providers that have a good rep (instavolt, osprey, ionity). It was all good tbh. The ionity charger at Gretna had my car battery management system going crazy to cope with the kw it was pumping, something I'd never experienced before ( before anyone starts bleatings about prices, I get free charging on all the networks I've mentioned). What I'm concerned about is if if will get worse to make long journeys in future with infrastructure not keeping up with adoption
What I’m concerned about is if if will get worse to make long journeys in future with infrastructure not keeping up with adoption
Yeah I'm concerned too. There is a lot of interest and planning for charger infrastructure but there are likely to be problems that might delay rollout. Like for example the state of the grid in rural areas.
I do wonder though how many families have an EV as their only car, or their main car?
Our i3 is our main car. The other car is my 18y old 3 series estate which is most definitely into the Trigger’s broom stage. 6500mi/y in the i3, 1500mi/y in the 3 series. I now pay more per year in VED tax than I do in fuel for the 3 series.
My soul is my only car.
Our i3 is our main car. The other car is my 18y old 3 series estate
But do you use the 3 series for the trips that don't work in the i3?

Free free ? Or someone else paying ?
Our main family car is my Tesla M3P and my wife has an ID3. We’ve done a few longish trips in the Tesla but can count on two hands the amount of times I’ve used the public charging infrastructure. We drove to Glasgow and back from Newcastle last year and charged at the super chargers just outside the city - a bank of 12 150kW chargers and not a single other car in sight 🙂. I’m glad we topped up there as we stopped at Gretna further down the road for food and as above it was rammed!
Real test will be this summer when we have a week in Cornwall booked so thick end of 1000 miles round trip. Even with the supercharger network I still get a little anxious and also worry more generally that adoption will outstrip infrastructure improvements.

free at point of use, but no doubt I'm paying for it in the deal. It's BP Pulse, instavolt, Shell Recharge (incl ionity, osprey and geniepoint) and Tesla superchargers when I had a Tesla. As a result I use the public infrastructure 100% of the time (I do have a home charger for emergencies, installed when they were cheap, but never use it). Luckily there's 2 very reliable Osprey 50kw a short walk from work and lots of Geniepoint 50kw in the local area.
The supercharger rank at Keele on Friday looked like a Model 3 owners club rally.
Interesting goings-on - continuing developments in battery tech
https://www.independent.co.uk/tech/battery-electric-car-lithium-sulfur-b2015456.html
Wow. If they can commercialise that, it will be a game changer. Less reliance on rare earth elements, 3 times the capacity and able to withstand more charge cycles before degradation compared to lithium ion. Seriously impressive stuff!
Interesting goings-on – continuing developments in battery tech
Li-ion batteries have only been around for 37 years vs 150 years for the ICE so we're only at the start of their development. Hopefully plenty more improvements coming.
What I’m concerned about is if if will get worse to make long journeys in future with infrastructure not keeping up with adoption
Lots of rapid charging hubs are now being installed by the likes of Instavolt, Orpey, MFG and Gridserve but even so I reckon the next year or two are going to be difficult especially at holiday times. Best to plan your journeys well and have a plan B, C and maybe even D for charging.
I do wonder though how many families have an EV as their only car, or their main car?
We sold our old diesel Merc last July so our e-Niro is our only car.
There are loads of developments like that on the way. See also solid state batteries.

Happy to see this but I'm worried they are installing them where they can, not where they are needed.
What's needed for widespread adoption is on-street charging in towns, particulaly residential areas. Doesn't need to be high speed, 7kw/11kw should suffice for an overnight charge every few days, or weekly/less for many people. Unfortunately, you just know that some people will insist on topping up every night, after getting back at 4pm an preventing anyone else from using them! I'm not sure what can be done to prevent that....
Long journeys yes, stick them at service stations etc but its teh day-to-day charging that most will struggle with when they don;t have a driveway.
Oh, and does anyone yet make an EV than can comfortably seat 5? Including child seats? Isuppose the eBerlingo, but that has a range of about 150miles I think, so not ideal...
Happy to see this but I’m worried they are installing them where they can, not where they are needed.
The Gridserve ones appear to be being built in useful locations- as long as you don't live in Scotland or Wales 🙂

Actually not sure. None on the M6, only two in the entire Midlands, one south of the M4. Looks a bit thin tbh. They need to be on the main transport corridors and going by that map they aren't except for the M4.
None on the M6
Perhaps I've misunderstood. I just looked on the Gridserve website and counted 13 on the M6.
I'm talking about the new 'charging hub' things with loads of high speed chargers. The existing ones labelled Gridserve are the old Ecotricity ones and are a bit shit.
But the point is that the fancy hubs seem to be going in (for now) where they can put them, not necessarily where they are needed strategically.

Bloody hell give them a chance they've only started. Gridserve have a big rapid hub on the M1 at Moto Rugby MSA which has been open for more than a year now. Other networks are expanding also. Osprey, Instavolt and MFG are all installing charging hubs. Instavolt have just doubled the size of their hub on the M40 at Banbury and Osprey have opened a hub near Instavolt at Banbury. MFG have a hubs open at Crow Orchard on the M6 and Filton on the M5.
I’m talking about the new ‘charging hub’ things with loads of high speed chargers. The existing ones labelled Gridserve are the old Ecotricity ones and are a bit shit.
Not so. Since they took over Electric Highway Gridserve have replaced 80% of the old Electric Highway chargers at MSAs with new rapids and the have only Welcome Break and EG MSA's to upgrade. There are very few old Ecotricity units left now.
They still seem to be in place in the M4 or they were 2 weeks ago anyway.
Evening gents, anyone got a Merc EQC ?
There are very few old Ecotricity units left now.
Are they also increasing numbers at each place?
Evening gents, anyone got a Merc EQC ?
No, but.. I have read that the EQA and EQC are Merc's first efforts at EVs, they are batteries stuffed into an ICE body and consequently not that good. The EQS and E are the purpose built EVs and apparently rather good. Although at that price they ought to be. EQE supposed to be released.. today, I think?
Any rumblings of a caddy maxi sized panel van with decent range yet?
Are they also increasing numbers at each place?
Only at the MSAs which will become charging hubs. Current list is Swansea (Moto), Heston West (Moto), Severn View (Moto), Wetherby (Moto), Burton in Kendall (Moto), Exeter (Moto), Woolley Edge North (Moto), Woolley Edge South (Moto), Thurrock (Moto), Leigh Delamere Westbound (Moto), Reading West (Moto).
Evening gents, anyone got a Merc EQC ?
No but Bjorn Nyland has tested one in winter in Norway. He's a bit long winded but he seemed pretty pleased with it despite its lack of interior space vs size of the car.
That EQE looks interesting. If you can get near predicted range i would imagine that will sell really well. I wonder how much it will be once you start speccing it up with the funky dash etc though.

Someone rents their car through Onto.
Good service to be fair, we've got an ID3 as a temp till at some point in 2025 our car is built.
I wonder how much it will be once you start speccing it up with the funky dash etc though.
On the EQS the fancy dash is a SIX GRAND option. That's a car designed to get as much money as possible from people with too much though, so it might be different on the E.
In other news, I got an email from Hyundai saying my car needed a 1yr service. Not exactly sure why, but at least it's only £72. They also offered to fit new windscreen wiper blades for £150. Lol, cheeky ****ers.
Had a look round an Ioniq 5 today. Looks great and was pretty decent inside.
Internet is awash with ID Buzz first drives today. Looks nice, proper launch in a couple of weeks. No price info yet but I'm guessing too much for me.
My VW Tiguan 2.0d DSG is due to go back in may (motability vehicle) and I’m considering getting a Hyundai Kona electric performance/ultimate as my replacement vehicle. It’s £1100 upfront payment and £260/month for 3 years, seems to have a very decent range and the level of equipment is a match for my current Tiguan so I’ve been browsing online reviews and can’t really find a bad word said against it apart from limited leg room which is not an issue as I very rarely carry anyone in the rear, anyone on here got experience of driving the Kona?.
No price info yet
Johnny Smith reckons circa £50k but I can't remember if that's the MPV or the cargo van.
Looks great apart from the under bumper grill - would love one but not at that price
Gonna watch that Late Brake tomorrow morning, been waiting for buzz details. Would love a cargo one if range is OK. Would have to be a pcp type arrangement and prob out of my range, but we can dream!
Would prefer a caddy size van, but...
anyone on here got experience of driving the Kona
I had one for 4 months. Good EV. Well priced- or at least it used to be. Efficiency is outstanding and performance is fantastic for what is a small family crossover. Downsides are very small boot, restricted space in the rear, cheap interior, jiggly ride and press button forward/reverse selector that drove me mad as I had to look down every time to use it.
I now have a Kia e-Niro which is built on the same platform but is better in every way. Better ride, better interior, more interior room, more boot space and it has a rotary gear selector which just falls to hand.
Cheers, I’ll phone Arnold Clark in Glasgow tmorn and see if they have a demo vehicle I can try out. The group are also dealers for pretty much all other makes so I’ll see what’s available around the same price.
Any rumblings of a caddy maxi sized panel van with decent range yet?
Can't help you with that but the guy who fitted our charger yesterday was driving a Vauxhall Vivaro E and was complaining he was only getting about 90 mile range compared with the claimed 200. And British Gas were thinking of putting ladders on the roof. He was also on a standard tariff so was paying £200 in electricity every month which he can claim back but still a lot of money.
anyone on here got experience of driving the Kona?.
I test drove one, ended up with the Ioniq EV, so the below is only relevant if the Kona is similar to the Ioniq which I am guessing it will be as it appeared the same. As a car the Kona was good, compact and roomy. Nothing to complain about in the driving experience at all. Comfy and not wallowy. The electronics are a bit of an irritation though. It bongs loudly and insistently at you as soon as it starts if you haven't already got your seatbelt on. Over the top of the startup jingle. Coupled with the beeps from the backup beepers to tell you you're still quite close to your garage door where you left it last night and sundry other beeps it's a bit of a cacophony. There's even one two-tone ba-bong, ba-bong sound that sometimes happens and is quite loud but I still don't know what it's actually for.
Whether or not this annoys you is down to your level of toleration for bongs, it didn't bother me much until my wife started complaining about it. The infotainment isn't particularly helpful or intuitive at times when trying to navigate either, and the UI for it is a bit rubbish. But other gadgets are great - the adaptive cruise is spot on, in my view for example. Oh, the only mild irritation in driving is that Eco mode limits power all the way through the throttle range until right at the end. So if you want to pull out of a junction on a slight hill, you can't do it quickly at all unless you mash the pedal to the floor. So you get either 60% power or 100% which is too much. However, it's fine in normal mode, and if I am in busy traffic I switch to normal. The modes are configurable though so you can set normal mode to have the eco air-conditioning setting and then you will still get the benefits of lower power consumption whilst being able to pull out of junctions quickly.
Give me a buzz with 350 mile range , option of removable rear seating and a payload of at least 750 kg and I’ll bite their arm off
Scared to even ask, but any rumours on price and date for a Kombi IDbuzz?
Cant blame them for prioritising the commercial version in the current climate though
I only watched the Late Brake Show video, which didn't suggest one would be prioritised over another - is that the case?
If so, works for me, as it'd be the panel van I'd want, but...
Keen to hear pricing on the 9th...
Revs - the 77kw battery has that WLPT of 200+ish range, so the 100kw battery option (alluded to, i gather?) should be 250-270ish?
I only watched the Late Brake Show video, which didn’t suggest one would be prioritised over another – is that the case?
I think its me thats wrong. That video above actually talked about the nice spec multivan type thing for the £50k.
The MEB platform can apparently do up to 111kWh packs which I'm guessing they can do on a cargo van, at the expense of a bit of payload. Would be 300+ miles easily.
If they stuck a caddy body on that, I'd order one today..!

Sounds about right . I heard them say on a different YouTube channel that they would be doing longer wheelbase models. The cargo model as it is, is not long enough to carry an 8x4 sheet . I suppose they will struggle to get a decent payload / decent size battery / decent internal size and keep it under 3.5 ton
About 7mins into that vid above they park it next to a T7 swb. 20cm shorter, and 20cm longer than a caddy, so its split the difference. Just eyeballing it some of that comes from a reduced bonnet? although the sloping windscreen may be tricking me here.
clearly what we all want to know is will a 6ft adult be able to sleep in it?
There's a decent video on the Guardian today.
I suspect most of us are aware of the messages it's trying to portray, but it's well put together.
https://www.theguardian.com/environment/video/2022/feb/24/how-green-are-electric-cars-video
decent internal size and keep it under 3.5 ton
I’m sure I’ve read something about an exemption to allow Electric vans to be 4T?
Not much out there on the ID Buzz Cargo, but looks ideal for my usage. Reported £42k starting price with 77kw battery, 250ish mile WLPT, 170kw CCS
https://insideevs.com/news/572425/vw-id-buzz-cargo-arrives-haul-stuff-style/
Looks well smart. wonder how much it'll be to lease 🤔
My caddy is in the garage for the third time this year already (knackered pads/discs, wheel bearing, coolant system) and is doing my head in!
Also was reading about the new Toyota platform, the bz4x. It'll have a towbar option, still waiting to find out how much it can pull.
Think that’s an optimistic view on ID Buzz pricing. I’m thinking mid (77kwh) battery will be high 40s, early 50s.
I’d love one but not at that price. Great to see more boxy MPV options though.
On friday I got a new Nissan Leaf through my work's salary sacrifice leasing scheme. It's only 40kw but 99% of the driving I do that's absolutely fine. Coming from a 2005 diesel Golf all I can say is wow, modern cars are so comfortable and nice to drive! The E-pedal mode is super cool as well.
Only slight worry is fitting two bikes in the back with the seats down looks like it will be a challenge, but I'm sure I can figure it out with the wheels off. I know the leaf isn't the fanciest EV but I am really liking it.
First real challenge will be a trip to Dyfi in a few weeks time from the FOD. Will need to charge once on the way there and back but there are fast chargers on the way from what I can see on zap map, I'm quite excited!
I know the leaf isn’t the fanciest EV but I am really liking it.
It was my favourite of the cheaper ones, but Ioniq's range was better which made a difference to us.

Yeah that's fair. I initially wanted to get an ID.4 but the leaf was literally the only one on the scheme without a 50 week wait, so that made the decision for me.

£42k quoted for the ID Buzz Cargo - so panel van, not MPV base. Think the ID Buzz will be closer to 50k for sure. But, prices not confirmed.
So, how much is a 2 year lease on a £56k EV (given i'd want a cargo but not base model!) with 10k miles PA?
£46k, not 56k!
WLTP Vs. real world post:
I had a pretty appalling journey in my Tesla M3P week before last from an efficiency perspective.. WLTP for the performance is 329 miles. It was showing 295 miles on 100% charge when I left due to the unique way Tesla calculates range (near perfect conditions). Journey was 105 miles from Newcastle to Leeds and it was raining heavy on the way down maybe 40% of the journey and snowing heavily for maybe 15 minutes. When I arrived at the office in Leeds it had gone from 295 to 125..
Now I do have a roof rack (Yakima aero bars) and 2 Thule 598s up top but even capping my speed at 70 mph other than maybe 2-3 times the battery was draining at a rate of knots. Pulled into Scotch Corner superchargers on the way home with about 20 miles in the battery in order to get home.
Pretty bad that a car advertised as having 329 miles range can't manage a 210 mile round trip (even with the rack and weather).
I'm driving thick end of 500 miles to Cornwall in June so the rack/carriers will be coming off for sure!!
There’s a video on the CarWow YouTube channel about the real life differences that roof racks, bike on roof, towing etc makes to an EV. Your numbers seem about right from the testing they did. Aerodynamic changes make a huge difference to EV range. They also tested the car (Enyaq) will all electronics off vs on, again a marked difference. I’m guessing all electronics off Will be the ‘perfect’ range conditions manufacturers quote.
I’ll have to give that a watch, thanks @stingmered.
It’s interesting how acutely aware you become of just how much energy it takes to move around a big metal box when it’s powered by electricity and not hydrocarbons.
I dread to think how much additional fuel I squandered when I was tooling about in my M135i with racks/carriers for 5 years. Shocking really when you take a step back..
As much as EV driving requires more planning and time I still don’t think I’ll ever go back to ICE unless it’s some very special sports car doing 1k a year as a 2nd car.
Why would you keep the rack/carriers on when you’re not using them anyway?
Lack of storage perhaps?
Also, all of your old ICE cars were advertised to do Xmpg, but in reality did Ympg which was 20-30% less. This is little different. Remove the racks, drop the speed by 10% and I’d bet you’re a lot closer to that predicted 295mile range.
Why would you keep the rack/carriers on when you’re not using them anyway?
Guess it depends how much you use them cause putting them on and off 2-3 times a week would be a misrable experiance.
I've just given up thinking about an Electric Car. I ordered an Audi Q4 in September last year with an expected delivery date in March. It then almost immediately got put back to April. Then again to May. Just after Christmas I was told not to expect delivery until August. That then stretched to January 2023. Then I found out last week that the majority of looms for VAG cars are manufactured in Ukraine.
My dealer basically told me they hadn't a clue regarding delivery but they weren't expecting any EV cars other than those currently in transit until next year, date unknown.
Though the price I was going to pay was fixed, the trade in value for my current car wasn't. As the delay was increasing, then the swap cost was also increasing.
I cancelled the order last week, and they're happy about returning my deposit.
What really boils my p*** is the dealer and VAG are still taking orders on cars they know they can't fulfil. Some poor punters are paying ing deposits and have expectations on something they'll probably never see.
I suspect other manufacturers are in the same boat. A combination of semi conductor shortage the Ukraine crisis and Brexit are going to make European built EV's almost impossible to get hold of.
@trailrat has it. The model 3 has no fixed mounting points* and aligning the racks per the manufacturer instructions to where they need to clamp is a king size pain in the arse. Plus the 598s don’t play particularly nice with t track and rubber seal thing.
*actually it does but they’re underneath the glass roof and the Tesla bars are £500 and lots of stories of smashed glass so I opted for the Yakima’s.
Roof rack used to slaughter the economy on my diesel car so must be 10 times worse on an EV.
Unfortunately it's weather dependent. Wet road means that you need to provide the energy to throw kilograms of water out of the tyres. Headwind is the same aerodynamically as driving faster, and so a 10mph headwind when you're doing 70mph is going to increase the consumption by ~40%.
Cold makes the air denser, and if you have a pre heat pump model that drains even more battery.
Not a huge fan of the Superchargers on the M1, they're a little too far off the motorway once you're past Birmingham to be convenient. Ferrybridge opening soon though.
Pretty bad that a car advertised as having 329 miles range can’t manage a 210 mile round trip
Well, as above racks make a huge difference as above, but Tesla are a bit more economical with truth than their cars are with electricity. Not only do they give a bit of a cheeky range figure but they also then tell you not to charge it to 100% all the time anyway. Other manufacturers cap the charge for you and take the hit in the marketing figures.
Some tests were done by What Car:
The Porsche Taycan does the best and in another US test it got an amazing 30% greater range than quoted! My Ioniq EV does a bit more than quoted around town in summer, a bit less on the motorway summer or winter.
Wet road means that you need to provide the energy to throw kilograms of water out of the tyres.
I'll qualify this - a properly wet road with standing water does indeed cost you a noticeable chunk of range or fuel; if it's just damp it's not too bad.
I did a 420 mile round trip today in my iX3
I covered around 230 miles and when I stopped to charge I had 42 miles left. WTLP is 281~285 so I was happy with that. That was cruise set at 65mph, aircon off. Noticed that aircon reduced the range by around 20 miles and the sat nav if turned on reduced it by around 10 miles
Amazing how many cars were going slower than me…
My ex left the roof bars (standard square ones) and 3 bike carriers (598) on her car for over 3 years, then took them off last summer. Instant addition of 150km range per tank. About 10%.
She only carries bikes on the roof about once a week (when she picks the kids up from mine). The rest of the time it's one or two bikes that usually go in the boot (for security) unless they are filthy. So maybe 200 journeys, 150 or more of which could have been done with a simple folding tow bar carrier.
Having seen the effect on the official WLTP testing with and without roof bars (Aero ones) and knowing how unrealistic these test cycles are, i use quick release aero bars and if i don't need them, they're stood in the corner of the garage!
I live in unconjested small town France, rarely use autoroutes and drive smoothly within speed limits in eco mode. I easily get what Renault claim even in Winter and in Summer I'm often around the 395km WLTP if the % battery display is accuarte - which it isn't, there is hidden capacity at the top and bottom. That suggests that in Summer my local driving is more economical than the WLTP cycle.
With my petrol car I averaged 5.8l/100km over the first few years of ownership which is what the official figures say.
Roof rack used to slaughter the economy on my diesel car so must be 10 times worse on an EV.
No the physics doesn't change just because its electric so it slaughters it by the same %. Problem is EVs have half the range of a diesel so 75% of 250 miles is 187 but 75% of 500 miles is 375 miles. Just means you have to "fill up" more often
The physics don’t change but the means by which an electric car generates power and torque do have significantly greater drawbacks at higher speed due to the lack of a gearbox to transfer power. Available torque in an EV is almost halved between 40 and 70mph, whilst available power also starts to drop between 60-70. If you add roof racks to the car and significantly change it’s CD (and the point of application) that halving point and power drop point come sooner in the curve. As such, you’re trying to use more power in an even less efficient part of the power/torque curves. ICE cars smooth out a lot of the changes in drivetrain inefficiency at varying speeds using a gearbox.
Tesla in particular have gone to significant lengths to get the best Cd figure they can. Adding roof racks ruins the secondary attachment line for the airflow and introduces turbulent air over almost 60% of the horizontal bodywork compared to 10-20% if left alone.
3 days of living with my ID4 and I'm liking it so far. Relatively easy to adapt to, although not having the gears in the middle does lead to the occasional looking list mid manoeuvre.
Mrs hoppy does seem to think she's disarming a bomb rather than driving a car for some reason but I'm sure she'll get used to it.
As such, you’re trying to use more power in an even less efficient part of the power/torque curves
Why do you think an EV less efficient at higher power?
Because they start to drop torque at round about 3000 rpm or so depending on motor and gearbox setup. Flat to that point. You gear for that , and the speed limit, or the speed you think most people will be driving.
Meanwhile , away from the keyboard I'm going climbing today in an old style Nissan Leaf, same as I have done for the last few years. No problems, works for me
Because they start to drop torque at round about 3000 rpm or so depending on motor and gearbox setup.
But why does that mean higher consumption?
Interesting article here: https://x-engineer.org/ev-design-electric-motor/#:~:text=Motor%20efficiency%20is%20up%20to,0%20%E2%80%93%20100%20kph%20acceleration%20time.
Looks like there is a fairly wide range of maximum efficiency and it's not a lot compared to aero losses of the car:
Fascinating how it is less efficient at super low speeds though. I wonder why.
Available torque in an EV is almost halved between 40 and 70mph, whilst available power also starts to drop between 60-70.
Was just about to post the same graph molgrips. None of the above affects the efficiency of the e-motor. Also EV speed is not generally power limited see below the power graph of an Hyundai Kona on a rolling road. Power is essentially flat until the limiter cuts in. I reckon it would easily do its top speed even with a roof box. The car would probably go way over the limited 103 mph with 200 bhp on tap but its probably limited to protect the battery
Ive said this before but EV's give you accurate real time efficiency numbers so any changes are immediately obvious. its a not as easy in the ICE so by the time you realise you only managed 300 miles from the last tank (rather then 400) you've kinda forgot about the things that have spanked your economy.
its probably limited to protect the battery
Yeah or to reduce the weight of cabling required.
