I would like to know if anyone out there can give me any feedback pros and cons on the 3:27 rear end v's the 3:55. I currently own a 1999 CVLX with every option, but due to a drivers door problem ford is replacing my car with a new 2000. I was told by my dealer that the 2000 would have the 3:27, but everything I have read indicates that it will have a 3:55. I am happy with the performance of the 3:27. Is the 3:55 performance worth the loss of gas mileage? Also what kind of mileage should I expect?

the tire size would be helpful. Maybe the 3.27 has a smaller diameter tire & wheel than the 3.55. Some Ford products usually have a 215 X ?, but the "Touring" option has the 225 X ? with a higher ratio. IMO, not much difference. Rather than fit a replacement driver's door on your 99, the factory is replacing the entire automobile? What other facts are we missing here? Pray tell.

If you have a 99 with all options, you have a 3:55 rear axle ratio. It is standard in 99 with the performance package.

When you compare 3.27 with 3.55 you're talking about perhaps a 9-10% loss in gas mileage. Don't know if it's worth the extra acceleration - I've only driven a CV w/3.55 ratio - perhaps it's worthwhile in emergency situations . Oh well, it's not bad if you can get a free upgrade to a new model year.

From what I've seen in the Edmunds spread, in the current model year the speed rating seems to be the only tire difference between the different axle ratios in the hdlg/perf & non-hdlg/perf pkgs. You're looking at 225/60SR16 vs. 225/60TR16...same diameter/width.

#105 of 3292 Axle ratios & Gas mileage

Actually the standard axle ratio in the CV and GM is 2.73. The handling and performance package has a 3.55 axle, which was increased from 3.27 for the '00 model year.
I have a '00 GM GS w/handling package, and so far am averaging around 22-23 mpg, 75% of which is highway. This may improve, as the car is barely broken in yet.
Anyway, I do have a question for the folks that know: what is the life expectancy of the rear air suspension? Has anyone had any major problems with it? Just wondering..

For what it's worth. Our 94 Towncar has 80,250 miles and the only parts we've replaced are the rear brake pads, coolant in the A/C, and tires. Not to worry about the air suspension and we often tow a 3500 lb boat/trlr. We are keeping this car until the Mercury Marauder appears.

My 99 cv does have a 3.27 axle. Not a 3.55. And does have the performance handling pkg. The 3.55 did not come on the 99. It is on the 2000. The door problem which caused ford to replace my vehicle was due to the drivers door not closing properly. This was due to a factory defect and could not be fixed without major repairs. The dealer tried to fix this problem 4 times without success. Ford did not want to admit that there was a problem, so I filed a Lemon law suit against ford, and won.

For what it's worth, I have the 3.55 axle on my '96 police interceptor with 100K miles on it. I get a consistent 18 mpg. That's driving in town or commuting on the freeway in very heavy (often stop and go) traffic. I also get the same mileage pulling a 1000 pound trailer on the interstate. I think my regular highway mileage (no trailer) is about 22. I would think a newer, civilian car with the 3.55 would do at least as well, but probably a little better.
