When the driver chooses the first mode, the car is under hybrid mode with work shared between the engine and electric motor, which is good for driving on expressways.

The driver can press a button to select the MAX eDrive mode, which means the car will be under pure electric drive, suited to driving in traffic heavy urban areas.

BMW's eDrive technology is specifically designed for new-energy vehicles.

Its electric driving mode can achieve zero emissions and its internal combustion gas engine allows for long distance driving.

The know-how comes from the BMW i family, which is the world's first premium new-energy vehicle brand.

BMW believes that the plug-in hybrid cars with eDrive technology are the most pragmatic solution to environment-friendly mobility.

In terms of fuel efficiency and emissions, the BMW 530 Le model boasts the lowest fuel consumption in the premium business sedan segment, according to the automaker.

Fuel consumption can be as low as 2 liters per 100 km depending on driving conditions, according to the company.

The plug-in hybrid car will reach more cities by the end of this year, according to the company.

BMW will offer and install a power box free of charge for 530 Le owners, which can charge the car by 80 percent in about three hours.
