The Crown Victoria Police Interceptor (known as the P71) is the law enforcement version of the Ford Crown Victoria.
Heavy-Duty Equipment includes electrical powertrain, heavy-duty frame with reinforcements, brakes and suspension.
The car has a (PCM) including logic to work with the (ECM) & 4.6L motor, transmission and rear end.
Tuned for more aggressive transmission shift points.Â Built for firmer and harder shifts.Â They also have aluminum driveshifts.
200 amp alternator & 78 ampere hour battery.Ford has had a near-monopoly on the market for police cruisers because of a preference for its conventional rear-wheel drive, V8 power, and body-on-frame construction, all suitable for police driving techniques. As one of the few remaining passenger cars using body-on-frame, it is rugged and enables inexpensive repairs after minor accidents without the need to straighten the chassis â€” an important benefit for a car frequently used by police forces for PIT maneuvers (ramming a car to spin it out) â€” making it preferable to unibody vehicles.
Engine: 4.6L Modular v8

They come equipped with many heavy duty parts such as a revised transmission, and a 250 hp (190 kW) engine.
Body and chassis
Another difference is Ford’s “severe duty” shock absorbers that offer a stiffer ride than the standard Crown Victoria. They also have black steel wheels with stainless steel or chromed plastic hubcaps.
All Police Interceptors also come with T-409 stainless steel dual exhaust systems without resonators. Standard Crown Victorias come with a stainless steel single exhaust system, while the Handling and Performance Package and LX Sport-equipped Crown Victorias have the same exhaust system as the Police Interceptor, with the resonators. The resonators further reduce noise, vibration, and harshness without adding any restriction to the exhaust system. Police Interceptors have higher-rate coil springs, approximately 0.8 inches (20.3 mm) of additional ground clearance, and thinner rear antiroll bars (shared with the LX Sport) than the Handling and Performance Package Crown Victorias; the base Crown Victoria does not have a rear antiroll bar.
Engine and drive train
The Police Interceptor is equipped with an external oil-to-coolant heat exchanger to reduce engine oil temperatures, allowing the vehicles to idle for extended lengths of time without overheating. The engine oil coolers are notorious for seeping oil from the O-ring seals after extensive use.
The Police Interceptor engine calibration comprises a slightly higher idle speed (by approximately 40 rpm) and minor changes in the emissions settings. The computer is tuned for more aggressive transmission shift points, and the transmission itself is built for firmer and harder shifts.
Ford used an aluminum metal matrix composite driveshaft for the 1993â€“2005 Police Interceptors as a measure to allow safe operation at over 150 mph (241 km/h), but it was more expensive than the regular aluminum driveshafts. Ford reintroduced the 3.55:1 rear axle ratio in the 2006 model year Police Interceptors, and set the speed limiter at 120 mph (193 km/h) to reduce the risk of driveline failure.
Police Interceptors also have a reinforced frame and body mounts, an aluminum drive shaft (aluminum metal matrix composite for the 1999â€“early 2001 model years), and an optional limited slip rear differential.
