In short 0-60 times are about 9 seconds and 1/4 mile is indeed about high 15's to 16's
BUT,
The Police car in it's full size form has a few variant's for transmissions and gearing, MOST are geared for highway usage.
And
It really hauls Ass from a 65 MPH cruising speed to about 130MPH. They are Geared for highway speeds and Very Good pickup from a cruising speed to top speed.
Cop cars either the older Caprices or the New Ford Crown Vics are NOT that quick. Fast and quick are two completely different things.
The feel you get when driving one is the Torque and NOT the Horsepower. Most cop cars with the exception of the Camaro's and Mustangs have had less than even 225 WHP. When you combine that HP with a 3,500 to 4K pound car and all the equipment the acceleration numbers are not going to be too impressive.
The Fastest and highest HP cars were the 95-96 Chevy Caprice/Impala crusiers right before they were discontinued.
I have owned 2 Caprice ex police cruisers with many good experiences and the torque is there to smoke the rear tires very well, and for their size the car handles remarkably well and has tons of room inside and is rather intimidating to drive on the open roads when it is outfitted again.
Police cars are NOT designed to be the fastest car, or be the quickest to any given speed even.
They are designed to be able to speed the longest and outlast what they are chasing. They have tranny and oil coolers, heavy duty hoses and belts, heavy duty alternators and full throttle power cutoffs and lock out torque convertor transmissions with Over Drives geared to over 150 MPH, extra large brakes, balanced driveshafts for safer more constant highspeeds without issue.
What stops the car from achieving anything higher than 130 to 140 MPH or so is the lightbar which produces so much drag at speed. The Chevy speedos were calibrated to 1 MPH increments, the Fords to 2 MPH increments, so the Fords are less accurate. But, don't try to argue your way out of a ticket with that information.
You may be able to outrun the cruiser but, you can Never outrun the radio and not frequently outrun a helicopter.
If you intend or try to outrun a cop then you are just plain Stupid and endangering other innocent citizens lives. And you deserve more than the sentences that they hand out for such an offence.
Cop cars ain't that fast but, if you know how to drive they can be pretty effective.
