Shanghai (ZXZC)- NIO, a Chinese electric car start-up, announced that its seven-seater SUV model ES8 will be launched on December 16th, which is set as NIO Day. On that day, the company will release the model’s price, performance and the battery swap system, etc.

The official definition for NIO Day is that it’s a party for NIO and its friends, not a kind of traditional enterprise conference. The annual event will be held at Beijing’s Wukesong Stadium this year.

As the company’s first mass-market model, ES8 was officially revealed at the Shanghai Auto Show. Its whole length is over 5 meters with a wheelbase of over 3  meters. ES8 is said to be powered by two electric motors and boast adaptive air suspension. Its swappable battery model may be its most outstanding feature and will bring users brilliant experience. Both its body and chassis are made of aluminium to reduce its weight.

At the beginning, ES8 was said to be slated for 2018. At the International Forum (TEDA) on Chinese Automotive Industry Development, William Li, founder and chairman of NIO, said ES8 would be launched in December. As to the manufacturing, NIO has established cooperation with JAC, which will produce vehicles for the start-up.

Though established only three years ago, NIO has set up a total of 19 offices around the world, including Shanghai, San Jose, Munich and London. Qin Lihong, one of the company’s co-founders, once revealed that it aims to be a global company and have ambitions to enter into America market.
