Jaguar Gets Out the Wagon Marketplace

Interesting, according to the website your Navigator has a 23 gallon tank compared to the 32 gallon tank my escalade has. Looked up the certified fuel pump filling speed, 23 gallons take 7 min. The gas industry has stated that the average 20 to 24 gallon fuel fill up take on average 8 minutes due to temperature, pump speed, how clean the fuel filter is in the pump equipment, etc. of course they also say the larger the tank the longer the fueling. So depending on how much gas you have in your tank it could be much shorter. So if you have a quarter tank of gas and are filling up, I can see this taking 5 min.

We live in different worlds, brother. It does not take more than 5 minutes at a pump to fill my Navigator. If I decide to walk inside and grab something to eat or drink, sure the time goes up. Just filling a tank though, 5 minutes. 

Refill time is only true if your driving a Subcompact or compact, much longer for mid size and especially full size ICE fuel tanks and then if you fuel at Costco or Walmart with their fuel discount, plan to spend 10 to 15 min in line if not longer before getting to the pump. Published paper from Standford University shows the average EV battery will also last 38% longer than current expected life as stated by the auto industry with the University requesting that auto companies test more realistically their battery packs.

I get that some are worse than others but a general 30% is pretty standard for the industry, as a whole. Yes, I'd need independent research for something I'd actually be buying, but most of those numbers aren't all that great.  Yes, I also realize that ICE vehicles lose about the same efficiency in the winter months as well. But, we also all know it only takes 5-10 minutes to replenish an ICE tank in the winter.

You have one problem here; your generalized 30% loss is not true for all EVs. More current testing shows that depending on the maker the range can be big like you stated but also very small. Hyundai and Kia showing the smallest battery loss in winter extreme weather and Tesla showing some of the largest loss. Even other stories where extreme testing was done in some of the most extreme Northern European countries showed at most around a 20% range hit on the latest EVs and of course up to 57% hit on 5-year-old EVs. Which brings up the value of a Heat Pump over traditional ICE heater, enhanced insulation of the battery pack, liquid temp managements and so many other new technologies that have been applied to the latest models. We have changed in 10 years what took Ice 50 years to do. This will continue to improve.
