Subaru Previews Plug-in Diesel Hybrid Boxer Engine With Viziv Concept

POSTED BY admin ON 05 March 2013

The Subaru Viziv Concept is Subaru’s interpretation for a future-generation crossover concept. Viziv, short for “Vision for Innovation” will be unveiled at the Geneva Motor Show later today.

Highlight of Subaru’s two-door, four seater concept is a lithium ion battery plug-in hybrid 2.0-litre Subaru Boxer diesel engine paired to a high torque compatible Lineartronic (CVT). The Viziv’s hybrid powertrain has three motor, including one installed within the transmission that provides both propulsion and regenerative braking functions. Two independent rear motors combine to provide Subaru’s trademark symmetrical AWD function.

The two independent rear motor setup to fine-tune control of the four wheels to match the travel environment and road surface conditions.

By actively varying the power split between the front and rear wheels, Subaru says the setup is able to deliver an “on-the-rail” like cornering ability. When cornering, the rear drive system provides more torque to the outside rear wheel and less to the inside rear wheel to generate inner-directed yaw momentum on the vehicle.

Besides improving dynamic abilities, the system also provides a safer handling. For example, when a driver turns the steering wheel towards a corner, the system increases drive power split to the rear, creating a handling characteristic that responds nimbly to driver operations. Returning the steering wheel to the centre position increases the power split to the front, creating a handling characteristic that emphasizes stability.
