Subaru’s renowned Symmetrical AWD platform and its core tenets of horizontal symmetry and low centre of gravity are now available in their full potential in a hybrid package. The system features compact, high-performance motors and batteries mated to the Symmetrical AWD. The drive motor has been built into Subaru’s “Lineartronic(*1)” next-generation transmission system positioned low in the car’s body. The Hybrid Lineartronic has been newly developed while retaining the inherent benefits of the Lineartronic system, as well as optimising each and every component and improving fuel economy. A Boxer Engine has also been specially engineered to suit the hybrid platform, featuring the Subaru Boxer Engine with a modified compression ratio and reduced friction levels to deliver better fuel economy and operate with less noise. Fuel efficiency on the road is even better with “SI-DRIVE(*2)” and “ECO Cruise Control(*3)” functions designed for optimum control to suit the driving conditions. The hybrid platform not only delivers outstanding fuel efficiency and impressive performance, but also brings a well-balanced design to all aspects of the car, including the driving power, interior comfort and ease-of-use that Subaru is famous for.
