Here in the Netherlands, we'd translate 31mpg to "1 per 11". One can drive 11km on 1L of fuel. 1 per 11 is a joke. It's associated with heavy petrol cars from the 80s and 90s, before anybody even attempted efficiency. Even my 15 year old diesel car had an efficiency of 1/22. Adjust you driving style and I'd get 1/25. Range: 1000km, with an ordinary sized tank. It seems Americans haven't even started with efficiency,…

What's with these weird, grandiose generalizations I've been seeing about America on this site, based on single data points? Do you realize that other brands and models exist in the USA? Do you realize Tesla is and American company? Did you even check look into Chevy Cruze's mileage? Here's a guy getting 70mpg in a Chevy Cruze by driving 55mph on the highway. That's 30km/l. https://www.caranddriver.com/news/a15341744…

Tesla is not an efficiency king either though... My 2016 ioniq does ~12kWh/100km whereas tesla is closer to 22kWh/100km

You may not have a choice in the matter as more and more countries are thinking of/implementing ICE bans in the near future.

I’m afraid these bans get systematically sabotaged by well funded ice lobby groups. Just look at what happened to the EU’s ice ban for personal vehicles. Spoiler: while new gasoline burning cars are technically banned after 2035 it will be completely legal to sell new gasoline burning cars by labelling them e-fuel only…

With Sodium batteries, range and infrastructure improvement and BYD showing they can make EV as cheap if not cheaper than ICE. I'm convinced a EV future in Eurasia is secured, how it will be handled in the west im not so sure given how they are Isolating themselves more and more becoming fortress NATO.

It's the main problem, as far as I can tell. I guess charging / "pump" time is an issue for cross-country road trips, but my personal needs would be entirely met by home charging.

Home charging isn't a thing for vast majority of car owners

Anyone with a house and an EV can do it. I don't have an EV yet but some friends just stayed for a week with a rented Tesla, and charging it up in the garage every night worked great, even with just a regular 120V outlet available.

"Half the efficiency" is highly optimistic. Afaik making synfuels loses about 70% of the energy and then you burn the stuff in an engine that is at best 40% efficient. Meanwhile EVs have >70% wind turbine to wheel motion efficiency.

You can do better than that if you use the waste heat from thermal plants. Both for hydrogen production and co2 capture.

Do you have any papers about this? How much better is it? How much waste heat is available that can't be used for something better?

I just realized how much energy efficiency is being squeezed out of a Tesla. It's incredible. A normal diesel fueled sedan such as the Chevy Cruze diesel runs at about 31mpg, which is 13.2 km/l or 15.3 km/kg. Diesel has a mind-boggling 12700 Wh/kg energy density[1], which translates to an efficiency of ~827 Wh/km for the Chevy. By contrast, the Tesla Model S, has a ~540 kg battery[2]. At 272 Wh/kg (from the posted ar…

The Aptera gets 1000 miles on a 100 kWh battery. Porsche Taycan: 2 miles per kWh Tesla Model 3: 5 miles per kWh Lightyear Zero: 7 miles per kWh Aptera: 10 miles per kWh Source: https://www.youtube.com/watch?v=mpiH-Y-HOvE

> The Aptera gets 1000 miles on a 100 kWh battery.

The Aptera gets 0 miles on a 0 kWh battery because they've shipped 0 cars, right? Can I go buy one and drive it today?

My plan to buy an EV in the next five years may be realistic after all. Happy!

That's great but it seems prices of all new cars and especially EVS even with rebates are astronomically high.

I don't need launch control, giant screens, self drive etc. just a basic EV under $30K with standard dash gauges.

My 2021 volkswagen e-Up can easily do 10kWh/100km, but then it's pretty small and light.

Engineering first results.

Engineering first? From the company with 1 inch gaps between panels? From the company that had no mechanical handles in the back, so if the electrical stuff stopped working (say, because the battery was on fire), passengers in the back had to finish a puzzle to find out how to get out of the car?

My panels look great. i also never look at the outside, because I am inside enjoying it.

I guess if you care about panels gap and not performance, go ahead and get a Brokeswagon?

So how many people is that? Don't estimate house ownership or house rents on your circle of friends. What about cities, apartments with no means to install chargers? World is not urban sprawl where houses have garage and power available for charging cars.

"CATL has announced a new “condensed” battery with 500 Wh/kg which it says will go into mass production this year" This is a lot more credible than most of the battery stories, because CATL is already producing a ton of batteries, lending them some credibility. This is a little under 2x the density of current batteries.

>This is a little under 2x the density of [the best] current batteries. [brackets mine] But the best batteries contain unacceptably high levels of cobalt. Practical EV batteries are made with nickel or iron, maybe vanadium someday, and have lower density than pure LiCoO2. >CATL is already producing a ton of batteries, lending them some credibility. A couple of years ago CATL claimed that they had figured out how to m…

What makes the Cobalt unacceptable?
