       | A) Even true

       | B) Not just them putting a huge gas tank in it

       | I mean there are no specs in this document at all

         | They claim it does 2.9L\100Km [1] or 34.5km\l, that would mean
         | it need a 61l tank to be able to reach 2100km.

         | Bragging about maximum range on a phav is stupid at least for
         | the next 10 years because there's going to be plenty of gas
         | stations

           | hit.

         | The range claimed by chinese car companies is usually accurate
         | (every article I've seen where a driver is interviewed includes
         | a reported range that matches the manufacturer claims) maybe
         | it's something about not wanting to run afoul of a government
         | that will kill you for abusive capitalistic behavior. No value
         | judgment either way is implied.

       | All gas cars can get big range numbers like the headline with a
       | bigger tank. It is 81mpg with an empty battery though which is
       | the more impressive stat.

         | My first car had a 300-400 mile range, because it had a factory
         | option 33 gallon (US) tank and up to 12 mpg. If there was room
         | for a 33 gallon tank on my C-MAX PHEV, I'd have range in line
         | with this announcement; cannonball run in maybe one gas stop
         | here we come; although I don't think the efficiency holds up at
         | cannonball run speeds which are awful close to the c-max
         | maximum speed and recent runs have used 65+ gallon tanks.
         | 
         | IMHO, in reality, anything between 300-600 miles of reliable
         | range is fine for a car that uses readily available liquid
         | fuel. That seems to be where the US market seems to have
         | optimized for in the past few decades.

         | 81mpg is extremely impressive. The best MPG cars available in
         | North America top out at the high 40s and low 50s. 81mpg is +30
         | over the Prius.

           | My car is nearly 10 years old, so either I somehow managed to
           | obtain the world's best Prius (with no loss of hybrid battery
           | capacity over time), or you're underestimating the
           | capabilities of today's hybrid gas-electric vehicles.

           | Well, my TDI got 60 mpg+ on the highway, which was better
           | than the EPA estimate, but then everybody got mad at VW.

       | Nice. And it's not even about the battery. BYD uses mostly
       | lithium-iron phosphate batteries, which are cheap and safe but
       | heavier than lithium-ion.
       | 
       | On the all-electric front, CATL has announced a battery with a 10
       | minute charge time for 600km.[1] It's an incremental improvement
       | on lithium-iron phosphate batteries, not a new battery
       | technology. CATL is the world's largest EV battery maker. They're
       | from Ningde, close to the necessary minerals. So this is probably
       | for real.
