Do you have a new EV? My 2015 Model S 70D has a nominal range of 330 km and as far as i can tell it does pretty close to that unless I am running at high speed (110 km/h or more) or doing a lot of hill climbing. So I'm pretty sure that a newer EV, especially a lighter one or one with a larger battery and lower power motor would have a longer range.
140 km/h and above is not a normal highway speed in any country except Germany and even there it is not really that common. I returned from the UK to Norway last week. It was about 26 hours of driving through France, Belgium, Netherlands, Germany, Denmark, the amount of time I spent at more than 130 was just a couple of hours.
my vacation this year was 1500 km one way, at least 80% of which was done at 130km/h or more (both ways). i was one of very many doing a trip of this length judging by license plates at the destination.
So you were exceeding the speed limit almost all the way? My journey was a similar distance and only the German stretch had any roads with speed limit higher than 130 km/h. Perhaps next time I do it I should record the speed as I go. The average speed was probably about 60 km/h so the amount of driving above 130 must have been quite small, some of it was a lot faster than that though, just for fun on the autobahn.
And of course the vast bulk of traffic on the roads is very much slower. Also quite a lot of ICE cars are not built for sustained driving at high speeds anyway.
I'm my above story, speed limit was generally 100/110kph and involved constant hill climbing. It would have been a test for any Tesla. Lots of point-of-no-return driving where the links between chargers was more than 1/2 of total range, which is scary in avalanche/fire/flood country.
Thanks, I misremembered it, I thought it was 130 km/h. But that still doesn't change the fact that most driving is at far lower speeds, even on the motorway.
Also 140-160 km/h aren't normal highway speed. They are in fact illegal in almost all countries.
