Volkswagen has assembled the final VR-6 engine, marking the end of its production after nearly 34 years.The VR-6 engine was first introduced in 1991 and has been used in various VW models as well as non-VW vehicles.The rise of turbocharged inline-four engines with better fuel efficiency and power made the VR-6 obsolete.VW's decision to discontinue the VR-6 engine is driven by the need to achieve economies of scale with modern four-cylinder engines.
