Another German carmaker BMW is showing six imported models this year, including its flagship iX and the first-ever i4.

The carmaker said the iX will be launched within this year, and the i4 will be available in the Chinese market soon.

"The CIIE is the world's first national-level expo with the theme of imports, demonstrating the determination and confidence of China's opening-up and the great potential of the Chinese market," said Jochen Goller, president and CEO of BMW Group Region China.

He said BMW will promote open cooperation for a win-win result, and make continuous contribution to the community.

"Apart from offering diversified products and seamless customer experience for our Chinese customers, we will continue our investment on the Chinese market and fully support China's low-carbon economy," said Goller.

GM, the largest carmaker in the United States, is showing its electric GMC Hummer, the Chevrolet Corvette Stingray Convertible and the Chevrolet Silverado pickup.

"The positive feedback we received for our halo products shown at the first three CIIE has been tremendously helpful to our business planning," said Blissett, GM executive vice-president and president of GM China.

"We are making steady progress in introducing the displays at CIIE to the domestic marketplace to satisfy the increasingly diversified needs of local consumers in the era of high-quality development," he said.

The carmaker is also showing its Ultium platform for electric vehicles. GM said Ultium provides the power, range and flexibility to make almost every vehicle an EV and also offers an ideal technical pathway for intelligent and connected driving.
