Petrol may be the "most appealing" when you look at on vehicle cost alone, when if you consider the cost of maintenance/fuel as well, then the EV is likely to be cheaper over all. Not only would its tax be zero (petrol anything from £20 to £400), but the cost to recharge its batterly would be as low as £3.50 (50kW @ 7p kWh when charge at night on economy 7 rates) vs refueling a petrol/diesel tank for £62/£65. So if you refueled twice a month, your already nipping at the door of an EV in terms of cost of ownership. More than twice a month and the EV becomes an absolute bargain. When you add on general maintenance as well then the costs really start to spiral.
If I were in a position to buy a new car now, I wouldn't think twice about it, i'd get an electric car regardless and I live in a flat, the infrastructure is there for charging if needed in an emergency but a cable out the window would suffice for the time being.
Why not look at the total cost of ownership over the period the car is owned, rather than just the upfront cost?
What is the difference in deprecation, fuel costs, servicing and maintenance costs, between the two vehicles? Also where did you get the costs from?
The prices are taken from Peugeot's website and discounts from broadspeed (£2.5k petrol and £1k electric). Depreciation accounted for in PCP deal.
The Petrol car's first year of tax is included, but from year 2 it'll be £140, or £12 a month.
A Nissan leaf first serice is apparently £120-150 from what owners are saying. So you're saving less than £100 a year in servicing. So probably less than a tenner a month.
Fuel obviously is a big variable depending on milage. Doing 8,000 miles a year would cost about £95 a month in petrol, being realistic. That would be approximately 4 charge cycles, realistically. So Prehaps £14.
Adding all that together does save approximately £100 a month. Based on this rudamentary maths, 16,000 miles a year would see a break even point.
I would like an electric car, because I can get away with it as long as we keep our other car which is a diesel VW Touran. I just want to see something affordable that makes sense. Maybe a VW id3, but we'll have to see.
