The culture of innovation at Nissan has helped to fuel one of the most dramatic corporate turnarounds in the past two decades and the company is still pushing boundaries – particularly in the clean technology space. Nissan’s 15-year old strategic partnership with Renault (the two companies are cross-shareholders and share a CEO) has provided a model for technological collaboration in the auto industry. But Nissan is also eager to work with competitors; it has been jointly developing fuel cells with Ford and Daimler AG since 2013, and when Tesla announced it would not initiate litigation against companies that used its patents in good faith, Nissan reportedly jumped at the opportunity to discuss technology sharing. With the Leaf’s status as the top-selling electric car on the market, Nissan will surely help to shape the next generation of green automotive technology.
