You can’t go by the stated petrol range @kezo as, just the same as with a petrol car, the range is based on the fuel remaining and the recent mpg average. As of when I left yesterday the petrol engine hadn’t been used, so the 350 was probably wildly inaccurate. The 313 would be a bit more accurate as the petrol engine was used a bit but still won’t be spot on. To illustrate the point I’ve just driven in EV mode only with no petrol use at all and the petrol range has dropped by 10 miles 😂🤔 I’m confident that my maths are right but there’s a small degree of guesstimating that will be tidied up when I fill up.
