According to industry experts, German car manufacturers will have to work harder to keep up with the rapid development of electric cars in China.

"As far as electromobility is concerned, you have to say that they hardly drive at all," said the independent German management consultant Peter Hage at the international motor show in Beijing.

Overall, German manufacturers have "so far had very few models really on sale".

German car manufacturers enjoy a high reputation in China.

"You could do a lot more business with your brand, but so far you don't have the products," said Hage, who has worked in the auto industry in China for 16 years and founded the Beijing-based consulting firm Districom Group.

"The longer this situation prevails, the more it is possible for other providers, especially Tesla, to occupy this field," warned Hage.

"You have to be very careful not to be left behind if you don't invest," said expert Stefan Bratzel from the Center of Automotive Management in Bergisch Gladbach.

"The lead market for electromobility is China - and by a considerable margin."

China's government is doing a lot for the promotion. There are subsidies and other incentives for buyers.

Metropolitan areas restrict the registration of gasoline vehicles.

Charging stations would be expanded.

The Chinese are also open to technical innovations, usually lead in the city and shorter distances across the country.

China is considered to be the largest market for electric cars in the world.

Volkswagen recently announced that it would significantly increase its investments in electric mobility in the country.

VW plans to deliver up to 1.5 million electric cars in China by 2025.

According to a McKinsey study, a total of around 1.2 million electric vehicles were sold in China last year.
