Info on the Humberside car from UK Speedtrap guide.

"The Ford Escort RS Cosworth., was currently in use in Humberside, is a development vehicle based upon the standard model available to the public. Members of the Vehicle Crime Unit teamed up with Ford Motor Sport and Ford Special Vehicle Engineering, to develop one of the most sophisticated Police cars ever to be constructed.

The end product of the research and development is a 250 brake horse power, 16 valve, turbo charged 'Super Car', which is fitted with permanent four-wheel drive. The acceleration rate of this vehicle is shatteringly quick 0 to 60 miles per hour (mph) in 5 seconds, with a top speed of 150+ mph.

This level of performance, coupled with the safety of four-wheel drive and brakes which are almost as incredible as the engine, make the Cosworth one of the safest vehicles available for this type of application. Other special components fitted to the vehicle include competition suspension, competition wheels, under-body protection and specially developed tyres. "
