There is fierce competition for the world's fastest police car with the Italians and Germans vying for the title.
Up until now the fastest police car is the Lamborghini Gallardo which an Italian police patrol is using.
It is capable of hitting a top speed of 192mph, which is probably ample to keep up with the most reckless of motorists.
But the Germans have their eye on a car which would leave the Lamborghini trailing in its wake.
It has placed an order for a Mercedes Brabus CLS V12 S Rocket, 730HP which has a top speed of 225mph. It is currently the world"s fastest street legal Sedan.
