New York City could possibly be the best place in the world for a
Hybrid Police car. NYC is obviously a dense city, where speed and
power of the old Crown Vics would be wasted energy. Apparently I'm
not the only one who thought so, so the NYPD has just purchased a
fleet of 40 hybrid cars.

This is the first step in an effort to reduce the Manhattan green
house gases by as much as 30% by 2017. A very lofty and worthy goal
for any city, but especially one as large and trend setting as New
York. Furthermore, this first step to reduce emissions will only
benefit a portion of NYC. The 40 hybrid police cars are expected to
only handle a handful of precincts. Namely the precincts with the
most stop and go traffic or long patrol areas.
