Evergrande Auto, the car-making arm of China's largest real estate developer Evergrande Group, presented its Hengchi lineup at the Shanghai auto show in late April, and now patent drawings for the Hengchi 1 showcase the model's design.

The patent drawings appear in the China National Intellectual Property Administration's (CNIPA) database and include design details of the Hengchi 1 from all angles.

The Hengchi 1 was designed by former BMW design director Anders Warming, and the coupe-like short rear end adds to the car's sporty atmosphere.

According to previously announced data, Hengchi 1 is 5,320mm long and has a wheelbase of 3,170mm, which is longer than the new Mercedes-Benz S-Class.

Evergrande Auto previously said that the Hengchi 1 is equipped with a one-touch summoning function, which allows users to summon the car via a cell phone app and let the driverless Hengchi 1 drive to a designated location automatically.

The new car is also equipped with a "transparent" A-pillar, which reduces the blind spot of the A-pillar and facilitates driving safety.

Evergrande Auto announced on June 6 the launch of summer calibration testing for five Hengchi vehicles.

The test was conducted in Turpan, Xinjiang, where the average summer daytime temperature is above 40°C. The five Hengchi 1, Hengchi 3, Hengchi 5, Hengchi 6 and Hengchi 7 vehicles were subjected to a series of extreme tests.

The test comprehensively verified the reliability and durability of Hengchi's battery, motor and electric control system, thermal management strategy, braking performance, battery performance, air conditioning system, and interior and exterior components.

In the fourth quarter of this year, the Hengchi series will start trial production, and next year will start deliveries, said Liu Yongzhuo, president of Evergrande New Energy Vehicle Group, at the launch ceremony.
