I’ve had my I4 since 1st March 2024 and have driven over 27000 miles. Just like petrol or diesel your efficiency is governed by your driving style. If you put it in sport and floor it then you can get as low as 2 miles per kwh and if you take it easy you can get over 4 miles per kwh withouttrying. On long journeys travelling at 70/75 mph with 4 people plus luggage in the car I normally average between 220/240 miles on a full charge. However in normal city driving it’s between 200/220 and that’s enjoying the car, I don’t see the point in having an I4 and driving everywhere constantly looking at my miles per kwh. If I do need to charge I use Tesla superchargers which cost between 23 to 37 pence per kwh with a membership at £8.99 a month so it isn’t an issue, especially as virtually all my charging is at home for 7 pence per kwh. The savings I’ve made are astronomical, less than £5 for a full charge and over 200 miles. I’ve never driven a car before that I can throw around country lanes and it still only cost at most 4 pence a mile. I had twst drive in lots of ev’s before picking the I4 and non compared to the comfort and driving experience. I would definitely recommend the I4 to anyone, if due to their disability it’s suitable.
