Define "car". Why wouldn't it be a car from super mileage competition? https://en.wikipedia.org/wiki/SAE_Supermileage_Competition https://en.wikipedia.org/wiki/SAE_Supermileage_Competition 3788 miles per gallon. 1610 km/L for the sane folks.

The video defines "car".

  Strangely, the definition from the video seems to be: * it can't have covered wheels (apparently the Gen 1 Honda Insight is not a car) * it can't be too small (apparently the Smart car is not a car) * it doesn't matter if it's defective due to a lack of active cooling (a battery defect which forced Nissan into a settlement with Leaf owners[1]) A weird definition IMO, but there it is.

    Nothing strange about paying attention to commercial realities. > it can't have covered wheels (apparently the Gen 1 Honda Insight is not a car) Yes, it doesn't look good and precludes rear wheel steering. > it can't be too small (apparently the Smart car is not a car) Yes, need to fit people in it. > it doesn't matter if it's defective due to a lack of active cooling You're presupposing new battery chemistries will require active cooling. These aluminium-ion batteries, for example, don't mind getting hot: https://www.forbes.com/sites/michaeltaylor/2021/05/13/ev-range-breakthrough-as-new-aluminum-ion-battery-charges-60-times-faster-than-lithium-ion/ https://www.forbes.com/sites/michaeltaylor/2021/05/13/ev-ran... https://graphenemg.com/gmg-battery-performance-graphene-production/ https://graphenemg.com/gmg-battery-performance-graphene-prod... https://www.youtube.com/watch?v=5B6icvUBNzE https://www.youtube.com/watch?v=5B6icvUBNzE The main point of the EQXX is this is what you can achieve in a Mercedes with a 100 kWh battery. It's pretty good.

People still fit in small cars. It's obvious that all people don't fit in all cars (even this one). > You're presupposing new battery chemistries will require active cooling So apparently, what you really meant to say is "what you can achieve if I assume future battery technology." This is quite the about-face from your earlier position.

        What are you even trying to argue? "The vast majority of vehicles" won't achieve these levels of efficiency because they won't have active aero, glass fibre reinforced plastic springs in the suspension for weight reduction, or solar panels on the roof. Even the Lightyear 0 is less efficient. Here's your homework: show me the four door, four seater econobox that achieves the same levels of efficiency and range as the EQXX. Mercedes has thought this through more clearly than you have.
