Nissan leaf correct decision?

Some quick math here so it may be incorrect, please feel free to correct it.

Assumptions :
80 mile average range
£0.13 per kilowatt hour charge cost

So,
£150 * 24 = £3600
(10000 / 80) = 125 full charges per year
£0.13 * 24 = £3.12 per charge
125 * £3.12 = £390 * 2 Years = £780

Total = £4380 + Tax (If Any) + Other consumables

Doesn't seem too bad for a new car, not sure I’d want the limit of an 80 mile range however.
 
Ah OK, you were showing the Tax as a minus figure as you wont be paying it any more.

What car are you selling to replace with the Leaf?
 
Charging at work £30 per year unlimited, home has solar panels producing enough during the day. Milton Keynes rapid chargers £00.9 per Kw h. V6 mondeo ghia x , we have had it for 13 years and want to keep it

Does the M25 have quick charge points? :p

I pray OP isn't traveling clockwise - there's over a 50 mile gap between services on the M25 and the first set of services on the M1. With a ~80 mile range and having to drive past Heathrow and through several sets of roadworks there may have to be some pushing involved :D

Roadworks and traffic actually significantly boost range - generally the lower the average speed the greater the range. Ancillaries such as lights, heat or aircon use very little energy in comparison to the main motor.

Obviously this doesn't apply if you boot it from every stop though!

Hmm. The more this goes on, the less like a good decision it seems. If you keep the Mondeo then all the costs of the Leaf are additional to what you already spend (minus the saving in fuel), and its all to get a car that is less useful than the Mondeo.

The Leaf makes sense if its a second car and your selling its predecessor. It makes little sense if your keeping your current cars and adding the Leaf as an additional one, and then driving 125 miles to pick it up :p.

Sell the Mondeo.
 
If the Mondeo is worth a grand and your paying ~£500 for insurance and £235 tax, plus ~£100 a month fuel, getting rid of it "saves" you ~£4,000+. That saving covers the cost of the Leaf making the Leaf cost you £0 more than what you already spend.

If you keep the Mondeo, the Leaf costs you ~£4,000 and your only saving is the fuel (~£2,000).

Getting a Leaf, selling the Mondeo = correct decision.
Getting a Leaf, keeping the Mondeo = incorrect decision.

Driving 125 miles on a motorway in a Leaf = bad decision, whichever way you cut it :p

Yes lots, as does the M1. The M1 one has a few service stations where you can access the other side via a service road if the charge points (plural) on your side are broken/in use.

75mile on a tank of electric? And I assume these are best case lab conditions as well.

No, that's a comfortable realistic range even in this weather. NEDC range is around 125 miles, which is b******s

If you charge overnight daily on eco 7, you can expect to pay 6.5p per kWh which makes a decent difference to the sums.
 
But switching to an economy 7 tarrif, unless you already use one for heating, will mean your electric bills for daytime use will increase

I agree with most of the above, but it depends how often you'd use the petrol car as to whether it's worthwhile, and whether you would've ended up with 2 cars anyway?

Certainly on the scenario where you get the leaf and get rid of the mondeo, you end up driving a brand new car with fixed costs and a nicer drive for no more money.

Driving 125 miles on a motorway in a leaf is fine if it's not a regular thing. Charging points are plentiful and free particularly on the route the OP is suggesting.

They're not plentiful on that run though? Especially clockwise on the M25. There's no services between Cobham on the M25 and Toddington on the M1 - a stretch of 56 miles which is about twice the usual difference for services on the M1. Anti-clockwise is better at 29 miles but the M25 isn't a great road for services.

A) that's offset in this case by OPs solar panels

B) Eco 7 Tariffs can be had for Day=11.965 Night=4.806 vs Single tariff of 9.167 per kWh.

So based on the facts that the car will be the biggest consumer of electricity by a long shot, and that solar panels may very well provide all the power needed during the day for other stuff there could well be a case to go for Eco 7.

I haven't done a spreadsheet to prove it but I'd guess that's a more feasible option than thinking you'll use the solar panels to charge the car. From the top of my head, the max peak output of domestic panels is limited to 4kw with them often producing less that half that during daylight hours, which would be fine to run everything in your house (except high drain things like microwave, oven, kettle, iron etc.) but not enough to reliably charge the car without making it draw power from the grid too.

So does that mean you'll be adding an extra hour on to your journey bumming around services?

It annoys me enough that I need to refuel half way through a 160 mile journey just so I know I'm good until half way through the return without having to flap about finding a petrol station as soon as I arrive or want to leave and that takes all of 10 minutes!

What is someone is already using the charging point, the 30mins could become an hour!

Fair enough, that seems fine to me but everyone has to make their own choice about what they'd do. I would take that journey without a lot of planning and just stop when a services came by.

The OP has stated a saving of £100 a month in fuel, which suggests a couple of tanks go through the Mondeo each month currently.

The gap between services is 2/3 of the range of a vehicle which can only be topped up at specified locations - not like a standard car where you can pull off anywhere and find a petrol station or grab a jerry can.

And it runs around the busiest motorway in the country which is littered with roadworks and notorious for accidents and past one of the worlds busiest airports. If you get stuck in traffic you're going to have to switch everything off and freeze/overheat and be very bored without a radio or risk running out of charge.

It's not something I'd do without prior planning.
