Nissan has been selling a hybrid version of its Altima sedan for the past two years but the core technology of the vehicle, the petrol-electric hybrid drivetrain, is based on technology borrowed from Toyota.

Nissan has always promised to deliver a vehicle using its own proprietary hybrid drive system, and the company has now previewed that technology in the form of two new prototypes.

Under the ‘Nissan GT 2012’ business plan, the company has committed to zero-emission vehicle leadership, and has announced plans to introduce an electric vehicle (EV) in 2010.
