The Nissan NV 200 Mobility Taxi, built for New York City taxis, on display during the first press preview day at the New York International Auto Show March 27, 2013 in New York. - 

New York gets a new mayor this week -- Michael Bloomberg is being replaced by Bill De Blasio. And one of the things the new mayor will be looking at is the Taxi of Tomorrow:  a fleet of Nissan vehicles* that launched this fall, fitted with some custom technology absent in the usual yellow cab.

Former mayor Bloomberg pushed hard for the new cars, but their future is uncertain.

Nonetheless we hopped into one recently for a ride from Manhattan to the boro of Brooklyn, accompanied by Ted Mann, who covers transportation for the Wall Street Journal's greater New York section, to help detail some of the new cab's features.

CORRECTION: In an earlier version of this story we incorrectly described the new fleet of Nissan taxi cabs. The text has been corrected.
