Lots of great info Aerkuld.

If anyone ever gets to NY city, you'll see that it seems like most of the taxis are electric/hybrid. I have to think that's the ultimate torture test for pretty much any vehicle.

n 2005, New York introduced incentives to replace its current yellow cabs with electric hybrid vehicles such as the Toyota Prius and Ford Escape Hybrid.[57]
...The proportion of the taxi fleet made up of Crown Victorias has dropped over time. In 2010, it stood at about 60% of yellow cabs, as the number of Ford Escape Hybrid and Toyota Sienna minivans kept rising.[58] The percentage of Crown Victoria taxis in the city would be further undercut by the adoption of the similarly sized Toyota Camry Hybrids since 2010, and the Toyota Prius V. By 2015, the Ford Crown Victoria fleet would be nearly entirely replaced.

As of February 2011, New York City had around 4,300 hybrid taxis, representing almost 33% of the 13,237 taxis in service, and about 6,000 by September 2012, representing 59% of the taxis in service—the most in any city in North America.[63][64][65] By mid-2009, owners began retiring their original hybrid fleets after they accumulated between 300,000 and 350,000 miles per vehicle.[66][67]
