The company does have plans for a stronger lineup, although you won't see these new models for a while. It just introduced the EC6 (shown above), a "coupe SUV" that boasts a 0-62MPH time of 4.7 seconds and a claimed 382-mile range with a 100kWh battery pack. It also revamped its larger ES8 SUV with up to 360 miles of range. The updated ES8 won't ship until April, though, and the EC6 isn't slated to arrive until September. In the near term, it's counting on a sharp spike in deliveries that could see it move over 8,000 cars in the fourth quarter.

However, the Chinese car market isn't static. Tesla just started delivering its first cars made in the country, giving customers 15 Model 3 sedans made at its Gigafactory 3 in Shanghai. While there isn't a lot of overlap between the two lineups (the Model X is as close as Tesla gets), there's still a concern that Tesla could offer fierce competition for Nio and lure away EV customers who are more interested in aggressive pricing and a well-known name than the form factor or a homegrown brand.
