For the past 18 years, the cop car of choice for North American police forces has been a modified version of the Ford Crown Victoria. And here’s an interesting fact about the Crown Vic: it hasn’t been available to the general public since 2008. Here’s another: it looks like something your grandpa would drive. While police forces like the cars because of their V8 engines, rear-wheel-drive, and easy-to-repair body-on-frame construction, they have become aesthetically and technologically dated. It’s time for a change, so the Ford Motor Company is offering one - last Friday, they revealed a new purpose-built Police Interceptor, which will take over when the Crown Victoria goes out of production in late 2011. The Ford Taurus-based sedan is said to exceed the durability, safety, performance and fuel economy of the Crown Vic.
