The Chinese automotive market is not usually short on manufacturing rivalry. Tensions between local brands and traditional European giants are becoming increasingly visible, especially in the field of electrification.

This time, the protagonist is Volkswagen, which has just taken a significant step in a technology it viewed with some skepticism for years.

The German brand recently celebrated an industrial milestone with its Chinese partner SAIC. The first EA211 range extender motor destined for the new ID. 9X SUV rolled off the production line.

The announcement had a celebratory tone, but it quickly provoked reactions from local manufacturers who already master these types of systems.

One of the most striking comments came from Li Auto, a company that specializes precisely in extended-range electric vehicles, known as EREVs. The company's social media manager reacted ironically, leaving a message that quickly went viral: "Congratulations on an obsolete technology."

An old debate reignites

The criticism didn't come out of nowhere. The debate between pure electric vehicles and electric vehicles with range extenders has been raging in China for years.

In 2020, several Volkswagen executives in that country expressed doubts about the future of EREVs. At the time, they considered it a technical solution with limited potential and not the ideal path to full electrification.

The market landscape ultimately told a different story. Chinese brands like Li Auto achieved remarkable growth by focusing precisely on this hybrid formula that combines an electric battery with a small generator motor.

The commercial success of these models demonstrated that many drivers value having an alternative when the battery runs out.

especially in regions where charging infrastructure is still under development.

The new engine that changes Volkswagen's strategy

The system that Volkswagen has just presented marks a change in its approach to the Chinese market. The new generator is based on the EA211 1.5T EVO II engine, a well-known engine in the Asian country.

Since its launch in 2011, more than 20 million units of this engine family have been installed in China. For its new role as an electric generator, the engine block has been extensively adapted.

Instead of directly driving the wheels, this engine works as a power plant that charges the vehicle's battery when needed. The result is a model that functions primarily as an electric vehicle, but with the possibility of extending its range thanks to the generator.

Volkswagen incorporated several technologies to improve the system's efficiency. Among them is a variable geometry turbocharger that optimizes airflow and improves power generation.

It also uses a deep Miller cycle that promotes more efficient combustion.

The injectors operate at a pressure of 350 bar to achieve very precise fuel atomization, allowing for better use of every drop and reducing emissions.

Over 1,000 kilometers of range

The new ID. Era 9X SUV will be the first model to use this technology. According to initial data, the combination of battery and generator will allow for a total range of over 1,000 kilometers.

Much of that distance can be covered in all-electric mode, while the generator motor will kick in when necessary to maintain the battery charge.

The popularity of this type of vehicle in China is largely explained by the peace of mind they offer drivers. Many buyers see EREVs as an intermediate solution between traditional hybrids and pure electric vehicles.
