I think it is all a matter of presentation. Porsche and Jaguar choose to display the quoted range on the GoM when fully charged. I assume they then decrement the value at a higher rate than that suggested by the power consumed, to achieve more realistic values as the journey progresses. It would be interesting if you were able to compare the reduction in GoM readings to the trip change in SoC and the average m/kWh. to see if this, indeed, is the case.Good morning, I do indeed feel that the car should indicate 199 miles when fully charged. I am abundantly aware that there are many factors which will influence the actual mileage achieved, but I rather foolishly presumed that 199 would be the optimum starting point.
I run a Porsche Taycan Cross Turismo here in The UK, and it does at least show the manufacturers maximum claimed mileage range when fully charged. I have also run a Jaguar I-Pace in America since 2019, which also indicates the manufacturers claimed mileage range when fully charged. Both vehicles only achieve between 88% and 90% of the claimed maximum driving range, but I find this acceptable.
