By mid-2010 hybrid taxis accounted for nearly 50% of Vancouver's taxicab fleet.

The hybrid taxis began operating in February 2008, allowing EnviroCAB to become the first all-hybrid taxicab fleet in the United States.

In October 2009, a fleet of 26 Toyota Prius began operating in Phoenix, Arizona, becoming the country's second all-hybrid taxicab fleet after Arlington, Virginia.

Harry Heller, owner of a taxicab fleet, died of cancer Sunday at the Columbia-Presbyterian Medical Center in Manhattan.

Many of the major cities in the world are adding hybrid taxis to their taxicab fleets, led by San Francisco and New York City.

Cities require taxicab fleets to buy locally produced cars and foreign companies to purchase locally made parts.
