Subaru Viziv: All-wheel-drive for tomorrow

Date:4 May 2013 Tags:

A whole new take on Subaru’s symmetrical all-wheel drive is featured in this concept, which embodies the company’s new approach “Four-wheel management”.

VIZIV – “Vision for Innovation” – points the way to Subaru’s new design direction and future technologies. Besides being a pretty funky looking crossover, it incorporates green cred in the form of a diesel hybrid drivetrain.

The interior features innovative display tech, with an instrument panel that displays the operation status of Subaru’s driving assist “EyeSight” system, a rev counter and speedometer in a unique cylindrical design and custom information displays in front of the front passenger seat and in the rear seating area so other occupants can share the thrill (or the terror) of being in the driver’s seat.

The powertrain is a plug-in hybrid system that combines a 2,0-litre Subaru Boxer diesel engine and Lineartronic (CVT) transmission. The front motor drives the front wheels and generates electricity.

Because the rear wheels are separately driven by two independent electric motors, there is no need for a propshaft, freeing up more legroom via a lower floor. The system also allows handling to be optimised. Turning the steering wheel increases the drive power applied to the rear, creating a specific handling characteristic biased towards agility. Unwinding the steering wheel biases the drive power frontwards, emphasising stability. The individual rear wheel motors also allow torque to be distributed left-to-right, countering yaw and helping improve cornering stability.

On planet-friendly note, the Eco-Cruise “intelligent driving” mode combines EyeSight driving assistance with Intelligent and Sports modes. This fine-tunes power output according to driving conditions, detected by EyeSight’s stereo camera.
