About the technology behind the world’s best selling electric vehicle, called the Nissan LEAF. It’s a car to drive across town with the thought that you’re not pumping pollution, or adding to the traffic noise as you do. We speak with Nissan’s Vehicle Evaluation Manager Steve Groves to hear about the science of its battery and of the innovative technology in this car.
