@glos guy Wow, if you are only getting 479 miles and spending £17 on charging, you are doing something wrong, or your sums are incorrect. If you vehicle has a battery and an electric motor, like my one does…i get 900 miles out of £17 of charge. A few guys on here have only used one tank of petrol in 6 months of ownership. Granted. Ot everyone can run their phev purely on charging, but some can. Your figures for 479 miles are horrible.
Good morning. I’m not doing anything wrong and my sums are correct. You have to keep in mind that the economy from a PHEV will vary massively depending on the sort of journeys people make. I have already established that round trips which I can make entirely in EV mode are working out at less than half the price of those journeys in my previous X1, even though I have a standard tariff and pay 21p per kWh. For many PHEV drivers that’s pretty much all their driving. However, I also do regular journeys that are in excess of the EV range, which puts the car in the far less efficient (cost wise) HEV mode.
In order to compare my running costs to an ICE car I am doing the following calculations;
1) Keep a log of the cost of all charges between refuels (I repeat, I am paying 21p per kWh so my charging costs will be much higher than others)
2) Add the total charging costs between refuels to the cost of refuelling the car with petrol to give a grand total running costs.
3) Divide that total cost by the miles driven to give a cost per mile
4) In order to provide a comparison to an ICE car, divide that cost per mile into the price of a gallon of petrol. This gives the true mpg equivalent had all that expenditure been on petrol only.
Using this calculation, my true mpg equivalent had all my charging and fuel costs been spent on petrol gave me an ICE mpg equivalent of 51.3 mpg. This compares to my 3 year average in the X1 of 42.1 mpg. I expect the gap to widen further as I had more journeys that were in excess of the EV only range over the last few weeks than I would usually have, so I don’t think that result was bad at all, especially given my electricity charge. @kezo has also told me that fuel economy of the Tucson engine improves over time, which will also help.
Incidentally, the calculation I am using is exactly the same one that Harry’s Garage use to compare the charging costs of BEVs to an mpg equivalent. Others may disagree and have different ways of expressing their costs, and that’s fine. We are all entitled to do as we wish. However, in my case I wanted to see how the costs compared to my previous petrol car to see if I’d made the right decision and this seems the best way. Admittedly I can’t make an assessment on the first 479 miles alone, but there’s already a 9mpg equivalent improvement and I expect that gap to widen (hopefully considerably) over time, so I’m quite relaxed about it.
