CHANGCHUN - Hongqi, a brand under China's leading automaker FAW Group, launched two new concept models -- the S9, a supercar prototype with butterfly-doors, and the electric SUV E115.

Both of the models were unveiled at the ongoing Frankfurt Auto Show on Tuesday.

The S9 is the company's first super sports model, which boasts a maximum speed of 400 km/h and a 100-km acceleration within 1.9 seconds. It is equipped with a newly-developed V8T hybrid system with a maximum power of 1,400 horsepower.

E115 is Hongqi's smart electric SUV. The four-wheel-drive off-road vehicle with a single range of 600 km boasts an autopilot system and 0 to 100 km/h acceleration time in less than four seconds.

Hongqi, which means "Red Flag," was established in 1958, and has been used as the vehicle for parades at national celebrations.

The company has sped up a market-oriented reform in recent years through diversifying its product mix. It now sells six models including two sedans, two SUVs, an EV and a customized limousine.

In the first eight months of this year, it sold more than 52,000 vehicles, up 231 percent from a year earlier. In August it sold more than 10,000 vehicles.

The company has planned to boast 17 varieties of car models by 2025, including a number of new energy vehicles and SUVs.
