The 2011 Subaru Advanced Tourer Concept is the follow up to the original 2009 Subaru Hybrid Tourer Concept and once again demonstrates the Japanese automaker’s hybrid technology set to debut in production form in 2013.

Subaru describes its Advanced Tourer as a mid-size wagon designed to combine sporty driving, utility, and environmentally friendliness.

Power comes from a turbocharged and direct-injected horizontally-opposed ‘boxer’ engine displacing just 1.6-liters and matched with Subaru’s own Hybrid Electric Vehicle (HEV) technology. Drive is then channeled to all four wheels via a symmetrical all-wheel drive system and CVT.

A single motor system is used for its simple structure and light weight. The system has an Electric Vehicle (EV) mode, which allows all-wheel drive motion using only the motor at start-up and on low-speed drives. When decelerating, the regenerating mechanism uses the motor as a power generator.
