Had a Tesla Model Y for two months now and almost 6,000 miles. Total cost for charging £204.40 (home) £123.70 (Tesla Supercharger) and £121.57 (work) Previous car averaged £1,118 per month in petrol....
Looked at the Mercedes E diesel hybrid and with my maths still worked out £300 per month more than a Tesla. Didn't really want either, so went for the cheapest that way helps pay for a Super 3 😀
I've had the 3 for a year and 8,184 miles.
In the last 31 days I've pulled 170 kWh from the grid at a cost of £13.60, using Intelligent Octopus.
At 4.3 miles/ kWh that is about 731 miles or to put it another way 1.8p/mile...
Nothing else is that cheap: I know Neilda had the same sort of data.
They are so cheap to run it is hard to logically argue that any other care makes sense. Mine is wonderful, but at the same time not something that engages the driver.
What happens next depends as much on the next phase of the Plus 8 than anything else.
