While speculation over a next-generation Leaf or an all-new EV are rampant, Nissan is likely announcing Cortana integration for its cars. Microsoft has experimented with Cortana in cars for at least a year, having unveiled a Windows in the car concept in 2014. Microsoft has worked to integrate Cortana into the windshield of a car, allowing drivers to make restaurant reservations or see their favorite locations on a virtual map. Nissan previously used a special version of Windows in its cars to create its own interface and system. If the pair are working on Windows in vehicles, then we could be set to see exactly how Microsoft envisions Cortana inside cars later this week.
