Can you please explain your comment as I don't understand it.Don't forget the phev probs has a lot more power

You will have to ask the car or battery manufacturersYes, But the batteries are the same. Or are they? The battery manufacturers say their products are good at -20 deg C. Just curious.
Do you mean your Touareg? 4Motion is just VW's generic term for 4wd, covering the Haldex system on transverse-engined cars as well as the full-time 4wd used on Touareg and uses a Torsen centre diff to vary the front-rear split from it's nominal 40:60Not sure about % time in 4x4?
My last three were TODs. Torque on Demand. Very clever electronic stuff. The VW uses 4 Motion. Another clever electronic driven system which senses as and when drive to all four wheels is required. Most of the time it is 2WD
Just a general point to explain the variations. The Fiat Panda 4x4 was something els3 😉Do you mean your Touareg? 4Motion is just VW's generic term for 4wd, covering the Haldex system on transverse-engined cars as well as the full-time 4wd used on Touareg and uses a Torsen centre diff to vary the front-rear split from it's nominal 40:60
The variations of 4wd/AWD are very wide - and many models have had major changes over their production run.Just a general point to explain the variations. The Fiat Panda 4x4 was something els3 😉
The generation 5 haldex system is never 2 wheel drive.Not sure about % time in 4x4?

It has ice power and electric power.Can you please explain your comment as I don't understand it.
Whilst PHEV's do indeed have both ICE and Electric power, the way the power/torque can be delivered they're often less powerful than many pure EV's and some pure ICE versions.It has ice power and electric power.
It's increasingly difficult to use a system like "mile's per £" as one of the major components is the cost of fuel, or energy, so any such calculation is only accurate on the day the data was collected.As an aside I see Parker’s, the car guide people , now quote MPP. A very useful and meaningful tool imo.
Used as a yardstick for comparing how much fuel or energy all types of cars use, the miles per pound (mpp) figure helps people decide between different options by showing in simple terms how far you can go for your money.
I like the idea of normalising the energy used to kWh. It would allow a real comparison of ICE and EV, as well as petrol and diesel.It's increasingly difficult to use a system like "mile's per £" as one of the major components is the cost of fuel, or energy, so any such calculation is only accurate on the day the data was collected.
In fact all the common methods used to assess the fuel efficiency of any car are so affected by variables non of them will be accurate, and as we have seen with some of the figures from manufacturer's many are almost cloud cookooland optimistic, especially for hybrids. Look at how they often quote the fuel efficiency of PHEV often over 100 miles per gallon, but it's only achieved by using mains power to charge the battery, and the effect of that interms of energy used and it's cost is not included !
The best we can hope for is to use economy figures as a basis for comparison, assuming the methodology used is consistent.
I would much prefer to see a calculation which is based on a common set of factors such as energy used per unit distance or distance per unit of energy. I get the impression that the public are getting the hang of kWh, and it is fairly easy to convert a measure of petrol diesel or any fuel and to express it's energy content in the same way, so it should be possible to know how much energy has been put into a vehicle, and therefore what it's energy economy is even for multi-fuel vehicles such as hybrids, and express it. These figures won't change with prices. It would be up to the owner to work out the cost of the energy they use.
However this would still require the consumer to understand they are still only any value as a means of comparing vehicle efficiencies, and it's highly unlikely an average driver could match them in real driving conditions.
Similar issues surround the other running costs, Insurance and VED, these are all variables, and as a result the magazine's published figures will rarely match your personal experience.
It is useful, but SOOO dependant on prices. I looked at my Polestar. They quote 6 to 13.2 miles per pound, based on (I believe) WLTP figures and household vs public charging. That makes some sense. 6mp£ is about right for my 3.1 mpkWh charged at 49p per kWh in public. Public rapid chargers are indeed around that price. But last week, I was public charging at 30ppkWh or arround 10ppm or 10mp£. At home, I pay 7.5ppkWh overnight, or 2.5ppm or 40mp£. for 13.2mp£ you would need to pay 24ppkWh. Still possible.Cost per mile has been around for a long time, but it covers things such as depreciation, along with fuel costs for a fixed mileage.
Still the miles per pound is another useful tool.
I don't blame you Dusty, all the conversions are a nightmare. Quoting an EV in MPG equivalent in another way of doing it. For mine it is 318mpg when charged at home, 47mpg when charged on a public rapid, based on £1.70 a litre for petrol.Good scripts chaps but sadly lost on me. I’ll stick to MPG and Ilbs and ozs
I don't see the value in MPG equivalent for an EV - if I ever get an EV, I'd work in Miles per Kwh - but then I disregard NEDC and WLTP MPG figures as useless for IC cars anyway.I don't blame you Dusty, all the conversions are a nightmare.

Yep - comparing EVs via MPG is pointless (as it relies on cost of petrol or diesel to be useful). But if you want to figure out how an EV will (or wont) fit your use case, knowing how much it might cost you (or save you) in todays prices can be useful. Thats what Parkers miles per pound is attempting.I don't see the value in MPG equivalent for an EV - if I ever get an EV, I'd work in Miles per Kwh - but then I disregard NEDC and WLTP MPG figures as useless for IC cars anyway.
The American EPA City and Highway figures are much more useful - no point changing now for IC cars but they're useful for EVs, at least useful where the same model is sold in the UK.
Tobes, Thank you . The ordinary man in the street can relate to that even with the 0.001 variations 😜I don't blame you Dusty, all the conversions are a nightmare.

I believe if you call or message Octopus (rather than look at the web page) they will offer you a go! Tariff. If you are not already with them, I have a referral you can use.I always convert our Mini to MPG equivalent based on the current cheapest petrol in our area and our pretty awful unit cost for electricity which has now rocketed. Makes me know I'm saving and it has always been ingrained in me by my dad from birth! At Current prices for both electricity and petrol are giving us 140mpg ; we rarely charge away from home. We've only just got a smart meter so couldn't have any ev specific tariffs and of course, now they won't even quote you to change so we'll have to wait till hopefully things settle down a bit!
That great news i am with Octopus customerI believe if you call or message Octopus (rather than look at the web page) they will offer you a go! Tariff. If you are not already with them, I have a referral you can use.
