New York City Mayor Michael Bloomberg announced that he will order the city’s entire taxi fleet be converted to gas-electric hybrids by 2012. Bloomberg has instructed Matthew Daus, the commissioner of the New York City Taxi and Limousine Commission, to begin a cycle of replacement that will see 20 percent replaced each year until all of the city’s approximately 13,000 taxis are hybrids in 2012. The commission has approved eight models of hybrids for use on city streets: the Toyota Highlander, Lexus RX 400H, Ford Escape, Saturn VUE Green Line, the Toyota Prius, Toyota Camry, Honda Accord and Honda Civic.
