Charging losses? confused
Yep. Charging isn't 100% efficient, so to fill a 46kWh battery is going to take round 50kW of power.

What sort of deal are yiu getting on am electric Berlingo van?
Where are you getting those numbers from?

A quick check confirms a VW e-Up or Fiar 500e can be leased on 12k miles per year deal for £300-350 a month, so 30-35p per mile.

.
50kWh of energy.

And yes. If you ever use a public destination charger you'll often see the amount delivered at the charge post is higher than what you needed. I frequently empty my 10.5kWh battery and use 11.5-12kWh at the post.

If you bought that A4 and ran it for 5 years and 50k miles it’ll cost you significantly more than £17k, no?

Nearly ten grand in diesel alone.
Bit late getting back to you, this is what i am wanting to figure out. I have 3 choices, keep what I have, buy an electric family car or buy another equivalent to my current car (probably wouldn't bother with that option tbh as nothing wrong with my car). It's really between electric and keeping what I have given fuel prices have risen substantially, I'm interested now whether making the switch to an electric car of equivlanet spec would now make sense.

If I kept my current car for another 5 years and 50k miles (it would be on 140k at the end of that) it would continue to cost me approx 34/35p per mile all in. So I feel 34/35p per mile is a fair bench mark on what I could expect out of the car.

Cost to date £30,600 for 90,000 miles / 9 years (a)

Costs for 5 years
Diesel = £11000 (added a bit on)
Repairs, servicing, cambelt, tyres = £4950
Ins/Tax = £1725
Residual value = £2000
= £15675 (b)

a + b / 140000 miles = 33per mile.


If I could get an electric car all in for 35p per mile I would be breaking even which would be great as the perception is they are "cheaper to run". I don't think I can though but admit I don't fully understand the costs involved in charging. I can pick up say a Skoda Enyak 80kwh/Audi Etron 82kwh, c6mths old for approx £60,000.

Assuming it costs me £7,500 to 90,000 miles (I buy to keep, no point throwing it away after 2 or 3 years and creating carbon output on having another built) then, and are these assumptions fair:

Car = £60k
Electricity = £7.5k (90,000 miles)
Servicing and repairs £5k
Tyres = £2.5k
Insurance = £2k
Residual value = -£15k (?! who knows it will be old tech at 9 years old).

=£62,000/ 90k miles = 68 pence per mile so substanitally more expensive than my current car.

If I was to go down the ICE route, it seems the cost would be similar:

Car = £35k
Fuel = £25k ( added on to current prices but it is guess)
Service and repairs = £3.5k (based on current experience)
Tyres = £1.4k (current experience)
Ins + tax = £3k (current experience)
Residual = -£5k

=£62,900 = 69 pence per mile

Now there is some flexibility and the calcs are rough but with fuel prices as they currently are or a touch higher the cost of an electric car, all in, is very similar to buying an ICE car becuase the ICE is cheaper to buy in the first place. I'm concluding to just keep my current car for another 5 years, as it is circa half the cost per mile, and re-assess the situation in 5 years where hopefully the cost to buy an electric car will be less than a petrol/diesel, or such that it makes the deal more attractive.

I'm confident electric car prices will come down in the future as mass market forces bring the cost of manufacture down i.e ICE cars are far more complicated in parts but volume of manufacturer has bought the price down.

Good thread and I can see the switch to electric would make sense for the 24/36 mth lease type owner and that is great, they can bank roll the reduction in cost to manufacture through volume for me. Note for me a family car to me is a just a tool to do a job with some requirements and cost of ownership is important to me as I have 3 other classics I'd rather spend money in non sensible ways.

One magazine (Autocar?) used to have a cost per mile against their model summaries at the back of the magazine. That including everything, including depreciation, tax, fuel, service, VED, insurance. Yes, they were all ICEs at that point, but there was little below 50p a mile, the good stuff was up to and beyond £1 a mile. That was a good 8 years ago.

I’m still not sure I follow. Can you buy and run a nearly new EV for the same price as a 10 year old car? No, obviously not.

The 80kWh Enyaq starts at £41k, not £60k - not sure why you’d buy a used one for well over list.

… and in depreciation terms, it all depends if you count in residual value, or replacement cost. A BIG, BIG, difference.

Not that I'm aware of. Will have quite a few variables to it. Currently it's not considered a huge cost overhead.

Those figures are well off and not just by a small amount. Electricity for 90,000 miles would be more like £2k or less. Most EVs do about 3.5 miles per Kwh and overnight charging is about 7.5p per Kwh or less in some cases. Allowing for losses that's about £2k. Servicing again is much lower, a lot cheaper in fact than a petrol or diesel.

My home energy spend went up over £3000.00 per year if I switched to an EV tariff and that's before I even added the extra car charges.

I'm now on a Standard Variable rate at 28p

Apparently the Zoe is clever in using the motor as part of the charging circuit so saves some weight and hence kwh

£7.5k for electricity seems reasonable for an 90k miles in an eTron to be honest. Maybe more when prices go up in October.

The decision for me is I have run my car for 10 years at a rate of 34 pence per mile and I can continue to run my car at a rate of c34pence per mile. It should have been less from here on as it has done its depreciation but fuel prices have increased and with extra bills factored in I am thinking is it time to wave goodbye and get something else.

I thought an electric car may well offer a similar ownership prospect (financially) as I have had over the last decade for the next decade but actually on doing the sums it is going to be around double the cost (34p vs 68p per mile). Perhaps it will be a little less if the cars on autotrader are overinflated and it's better to buy new but it will still be considerably more. I would need the electric car to cost c£25-28k for the numbers to stack up to match or be close to my diesel ownership experience over the last 10 years and expected cost for the next 10 years.

I fully appreciate if you're a person already on the PCP/Lease hook then the cost of buying the car is almost irrelevant; you need a car, you're coming to the end of your term and you're used to the rental payment so in that case the petrol pump savings to switch to electric would seam beneficial ignoring the cost of the car. But I can't ignore it as it's still a cost to me.

Yeah I think 7.5p/kWh is a good best-case rate, but not everyone can and will get any better than circa 30p/kWh and over several years it'll likely be higher.

There was a good point made by a poster above me, which then urges me to seek opinions from you fellas….

I work as a sub-contractor (Courier). I drive around 40-45 miles a day. My current van is 17 years old and is past its best. It’s time for new.

Spurned on by the point of how much / little old tech is going to be worth in 10 years time, do I buy or do I lease? I’m a sole trader, not LTD and I’m not VAT registered.
