Which plug-in hybrid became the world’s best-selling plug-in hybrid vehicle in 2015?

The Mitsubishi Outlander PHEV became the world’s best-selling plug-in hybrid vehicle in 2015.

Mitsubishi introduced the Outlander PHEV in Japan in 2013 and then expanded sales into Europe and other markets. Its SUV body, all-wheel-drive system and ability to travel short distances using electricity helped distinguish it from many smaller plug-in hybrids.

The vehicle uses a petrol engine, electric motors and a rechargeable traction battery. It can operate electrically in suitable conditions, while the engine provides additional range and power when required.

The Outlander PHEV is sometimes confused with the Toyota Prius Plug-in, which was an earlier high-profile plug-in hybrid. The Outlander’s distinction was its combination of plug-in capability, SUV packaging and strong international sales.
