I keep seeing "Police Interceptor" on the back of the late model Crown Vic Police cars.....what engine is this? 4.6 or 5.4? is it hotter than a stock say '97 TBird 4.6?
I know the "PI" I keep hearing about on here is NOT "POLICE INTERCEPTOR" Thanks!

They have a 4.6 just like the regular CV. What makes it different engine wise is that it has an engine oil cooler and I think silicone hoses for the radiator. And probably a slightly better tune than the civilian model. Also, the cars have dual exhaust.

I think they have the suspension from the Sport model also, but not the center console.

mostly gears,i belive a slight tune on a stock PI motor, heavier duty cooling, and heavy duty suspension the sway bars are way bulkier than stock. I do oil changes on alot of the local cruisers and get to see underneath. They also have the fuel cell with feed lines from the sump from the look of it. And most of the new ones have an aluminum driveshaft but i cant remember if all the newer vics have them?

i dirve an interceptor every day:) chicago pd. the "interceptor package" is only available to municipalities. they have larger radiators, cooler thermostats, larger fans,a nd i different tune to keep them cool. the car is designed to be able to sit at idle for 8 hours in 110 degree summer heat with the hood closed, ac on, and no breeze and still not overheat. these cars are made for heavy duty driving for chases and "intercepting" violators. the new cars have the 3valve motors and the option of 3.27 or 3.55 gears. they are mor agressively tuned, have no governor, have a "calibrated" speedomoter, 17 inch rims (ont he newer models) larger alternators to handle loads from our computers, lights, cameras, etc, come prewired for optional equipment, come with bucket seats and stripped down luxery. the trunk automatically fully opens at the press of the botton to provide rear cover during shooting incidents, heavy duty shocks, and the list goes on......

cop car, cop shocks, cop brakes, cop motor. we got a full tank of gas, half a pack of ciggarettes, its dark and we're wearing sunglasses. (blues brothers)

It's a model made before catalytic converters so it'll run good on regular gas.

Then again, that's back when cars were built like an M1A1 Abrams. Some info on them can be found here:

I've contemplated picking up an old ISP car at an auction for a beater if I ever had the money. Then I figure for what they go for, I'd probably be able to pickup a decent used truck that hasn't been beat to hell and back.

the package is called P71 and there is a pretty good chance not every agency has the 05 and 06 models. Everything earlier had the 2v and they werent any different than any other 4.6. Although I have yet to see a P71 car with 17s, they all have 16s with hub caps. There are two officers in my apt complex who have brand new Vics.

I had a '98 and a '00 CVPI in sucession, and now I have a 2006 CVPI issued to me in a rather sharp looking Blue over Silver paint scheme, I have just turned 10,480 miles this morning as I came home. It has 3.27 gears where my '00 had 3.55 and my '98 had 3.27. The 2006 does have 17"x7" wheels and P235/55R17 Goodyears, which I really like for all around weather type police work on the big roads. It does have the aluminum metal matrix whatever driveshaft that does not rust a deep brown like that on my 2001 Mercury GM. The 2006 has headrest I don't like as it interfears with my trooper hat, it has side impact airbags, 2 stage driver air bag, and new for 2006 self collapsing steering collumn which must be re[placed if the drivers side air bag deploys. The 2006 shifts entirely electronically and winds it's motor to 5500-5700 in each gear before upshifts occurr. The CVPI package includes many frame reinforcements at strategic points, harder durometer rubber in the bushigs, heavy duty springs with no air aprings (unlike a sport which has rear air susp), special shock calibrations, increased effort steering, harder seat padding, special wiring harness with provisions for police equipement (light bar, strobes, radio, etc), higher output alternator, louder low restriction air cleaner (I think it's the Marauder's setup), modified tune, 2valve heads (3 valve heads are slated for 2008 or 2009 I'm told), extra trans, engine oil, and PS coolers, 2 trunk lock remotes, extra ground straps on exhaust and hood/trunk, two position red/white police dome "ticket" light, genuine AM/FM Stereo radio, bucket seats with a minimum of 7" between (for our radio console), 140 mph certified speedo (we check them every 4 - 6 months anyway and do our own certifications), tach, engine idle hour recorder, heavy duty special service engine oil drain plug sealing washer ring, and some other stuff maybe.



PS: .... Once upon a time police package cars engines were fitted with low tension piston rings, lower tension that standard which took longer to break in but which wore longer once broken in and which created less friction and heat in long periods of idling, I think now that all 4.6s are fitted thusly.

So Ford is going to continue the crown vic? A salesman at my local dealer told me they were going to cease production entirely...I only half-believe him though. Is what I heard true?

There's no difference in the engine between a standard CV or a P71 for the most part. I get a lot of people that swapped out their 4.6 for a police 4.6 thinking they are getting a HP version. Through the years there's been a lot a changes and too many to list. But the engine itself is nothing special and has nothing over the other CVs. Cooling, electronics, suspension are the main differences. They have a slightly different calibration in the EEC for higher shift points and firmer shifts. The trans has a longer output shaft so they have a shorting drive shaft to allow them to run at higher speeds so that don't vibrate. They all have speed limiters but they are just higher than the standard CV.

The 05 - 07 are pretty much the same but for some reason Ford went away from the standard MAF to the new style that is just an insert into a tube. The tube is part of the air box now so interchanging a MAF housing can be done. No 3V are yet available.

They are all rated at less hp than the Mustang's 4.6 SOHC 2V through all the years but the engines are the same. Just the upper intake is turned towards the driver's side. And in 03 they got KS.

That was just a test to see if anyone read it. :tongue:

I forgot HP is rated 250 on '06. Subjectively, the '06 drives and handles really sweet when loaded with all the cop stuff like flares, riot stuff, books, files, other gear (though, I liked my '98 and '00 as well when I had them as they were improvements over the '97 whichh I drove once and which scared the hell out iof me at 100 mph,, I was borrowing it while having work done on my '94 Caprice that day).

Great brakes too.

That's all .......... ;)

yes there was talk about the discontinuance of the cv. since the 96 caprice left the scene, there is no longer a 4 door full size frame rear wheel drive car to take over the market for police, fire and taxis. the dodge intrepid, impala, and now charger are all competeing, but still can not come close to the cv platform.

where the hell is Shenandoah Valley?

*cough*You've got to remember that the company that ruled the police car market for years (usually held anywhere from 45% to 60% of the market) has made its return to the V8, 4 door, RWD market.


It can outperform the Vic in Hemi form, and can hold its own with the 3.5 version.

I'm sorry, but I don't recognize the black and white cop car in the last picture, I'm getting the idea that it is a Chrysler product??
