You mixed up between EREV and PHEV. Li Auto cars are so popular in China is because Li cars are mostly EREV Extended Range EVs.
Does toyota even offer EREV?
I clearly wrote EREV referring to Li.
The difference is just engineering. The consumer doesn’t care whether the gasoline engine drives the car or not. BYD PHEV sales are still quite significant.
EREV gasoline efficiency is actually bad relative to a hybrid drivetrain in highway conditions, I showed the comparison many pages before between Li L9 and Grand Highlander. It doesn’t make it bad overall (it is cheaper to implement), but it’s a trade off to consider.
