In the first quarter of 2020, Chinese EV automaker Nio had almost gotten knocked out of the auto scene. But, thanks to an investment of $1 billion from the local government, Nio managed to get a second lease on life. It revealed the updated version of its electric, the ES8, and theres no looking back ever since. Nio is growing leaps and bounds and the launch of its latest EV is a testimony to that. The new electric sedan is called ET7. It will be offered with three different battery sizes, with the biggest of them all claiming to deliver 620 miles on a single charge! With pretty decent performance figures and tech features, can the ET7 take on the Tesla Model S successfully?
