Nio has revealed a new concept car that previews its first saloon model at the Shanghai motor show.

The ET Preview is said by insiders at the Chinese firm to be around 80% representative of an electric large saloon that’s due in production before 2021. It has a fastback bodystyle with an all-glass panoramic roof and alloy wheels inset with carbon fibre inserts for improved aerodynamics. Adaptive matrix LED headlights are said to mimic human eyes, while the rear lamps pulse to replicate a heartbeat. 

Inside, the car uses electromechanical door latches instead of traditional handles, and includes Nio's NOMI digital assistant to help the driver with infotainment and navigation. The always-connected system uses voice recognition for hands-free operation.

The ET acts as a demonstration of Nio's high-density nickel-cobalt-manganese battery pack and 220kW electric motor powertrain, which the company claims will deliver a cruising range of up to 317 miles under China's NEDC-based tests.

It will use high-efficiency permanent magnet motors to drive its front wheels, in conjunction with high-performance induction motors at the rear. It is understood to be closely related to the ES6 SUV. 

Nio has solely made SUVs to this point, after launching with the limited-edition EP9 electric hypercar.

The ES6 will enter production this June, joining the Audi Q7-sized ES8 in Nio’s range. It gets an NEDC range of 317 miles from its 84kWh battery pack.
