Den Einen oder Anderen interessiert vielleicht der Unterschied zwischen Police Interceptor und normalem Crown Vic. Der ist ganz beachtlich:

Comparison with the Crown VictoriaThere are few notable differences between the Police Interceptor and standard Crown Victoria or Grand Marquis. Both cars use the same Flex Fuel 4.6 L 2V SOHC V8, Ford Modular engine, and Ford 4-speed automatic transmission.
Engine and drive trainThe Police Interceptor is equipped with an external oil-to-engine-coolant oil cooler to reduce engine oil temperatures, allowing the vehicles to operate at high rpm/high loads for an extended period of time without the risk of engine oil overheating and subsequent engine damage. This engine oil cooler can be prone to seeping oil from the O-ring seals after the high mileage operation encountered by Police Interceptors, particularly where damaged by road salt.
The Police Interceptor engine calibration includes 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. The engine has slightly higher compression over the stock 4.6L used in non-police vehicles, at 9.6:1 vs 9.5:1. The EGR system is controlled differently on 03+ vehicles than on 03+ non-police vehicles.
The 2006–present Police Interceptors are mostly equipped with a 3.27:1 rear axle ratio and are electronically limited to 140 mph (225 km/h) due to critical driveline speed limitations, (an optional 3.55:1 trac loc rear axle ratio with 120 mph speed limiter was available but is rare). Pre-2006 Police Interceptors equipped with the 3.27:1 rear axle ratio were generally limited to approximately 131 mph (211 km/h). This is compares to the standard non-P71 2.73 rear axle ratio with a speed limitation of 110 mph (177 km/h) for all "civilian" Crown Victorias.
Ford used an aluminum metal matrix composite driveshaft for the 1993–2005 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 a 3.55:1 rear axle ratio for the 2006 model year Police Interceptors with a 120 mph (193 km/h) speed limitation to reduce the risk of driveshaft failure.
Police Interceptors also have a reinforced frame and body mounts and an optional limited slip rear differential.
Body and chassisAnother 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.
On 2004 and newer models, P71s have a 200 A alternator and a 78 A h battery.
Ford also offers trunk packages for equipment storage (see below), and as of 2005, has added an optional fire suppression system to the Police Interceptor.
The bulk of police car modifications, such as installation of emergency lights, sirens, passenger seat dividers, and plastic rear bench seats, are offered as aftermarket modifications by third parties.
InteriorMost Police Interceptors have a break in the front "bench seat" despite having the shifter on the steering column. This gap between seats is generally filled by a console holding radios, controls for emergency equipment, large firearms, and often a laptop computer or mobile data terminal (MDT). The Police Interceptor also has a calibrated 140 mph (225 km/h) speedometer.
