BMW:

The transition will see even the company’s top-selling 3 Series sport sedans turned into plug-in hybrids.
 
 The company is weary of the stringent European Union regulations that greatly reduce the average carbon emissions permitted from road vehicles. They are said to be tougher than either North American or Chinese emission levels.
 
 The current EU limits extend only to 2021, and is expected to be pulled down further lower through 2025. Under the pressure of regulation, BMWs of the future will be smooth, powerful-and largely electric.
