An Atlanta based start-up, Carbon Motors, wants to build police cars from the ground up. Currently, a city police department buys a passenger car, then has it modified by one or more after market shops in order to turn it into a police car. Carbon Motors say they can build a hi-tech "purpose-built police car" for about the same cost as a fully outfitted, modified car.
They will use a European built (my guess Mercedes-Benz) diesel capable of propelling the car to a governed top speed of 155MPH. It'll do 0-60 in 6.5 seconds and a quarter-mile in 14.5 seconds. It is specially designed to do PIT maneuvers. It also can come with license plate cams that read the plates and tell the officers in the car if the car is reported stolen or expired. You can read the spec sheet here.
They haven't yet got a factory built, but they say they've narrowed the site to five states.
I bet cops all over the country are in drool mode over this car. Can't say as I blame them.
