New York City taxicabs purchased after Oct. 1, 2008, will be required to get at least 25 miles per gallon, and those purchased after fall 2009 will have to get 30 mpg — so, basically, will have to be hybrids, according to a rule adopted by the city’s Taxi and Limousine Commission. The city’s iconic Crown Victoria cabs currently get around a measly 10 mpg.
