You are in the Lincoln Navigator
What is this discussion about?
Lincoln Navigator, SUV
#476 of 1637 Navigator Motor is the Weakest
May 18, 2003 (9:13 pm)
I believe the 4V motor was for 2000, not 1999. Try towing with it at altitude, and the need for a bigger motor becomes evident quite quickly:
2003 Lincoln Navigator
Premium 4WD 4dr SUV (5.4L 8cyl 4A)
300 hp 5000 rpm
355 ft-lbs. 2750 rpm
2003 Cadillac Escalade (6.0L 8cyl 4A)
345 hp 5200 rpm
Torque 380 ft-lbs. 4000 rpm
2003 Ford Excursion Limited (6.8L 10cyl 4A)
310 hp 4250 rpm
Torque 425 ft-lbs. 3250 rpm
2003 GMC Yukon XL Denali
320 hp 5000 rpm
Torque 360 ft-lbs. 4000 rpm
2003 HUMMER H2
Lux Series 4WD 4dr SUV (6.0L 8cyl 4A)
316 hp 5200 rpm
Torque 365 ft-lbs. 4000 rpm
2003 Mercedes-Benz G-Class
G55 AMG 4WD SUV (5.5L 8cyl 5A)
349 hp 5500 rpm
Torque 387 ft-lbs. 3000 rpm
2003 Porsche Cayenne
Turbo Tiptronic 4WD 4dr SUV (4.5L 8cyl Turbo 6A)
450 hp 6000 rpm

Give us a supercharger or V-10!
#478 of 1637 trouble with DVD navigation screen...
May 19, 2003 (4:26 am)
I recently bought an '03 Navigator with the new DVD based navigation system, and I find it nearly impossible to see the screen when the sun is shining and the sun roof is open. If I put sunglasses on, I can't see it at all unless I get within inches of it (not a great option while driving...). Unfortunately, I didn't discover this problem until after delivery because of all the rain and cloudy weather we've been having in the southeast.
I called Lincoln about the problem, and they said no one else had reported anything. I went back to the dealership and drove another '03 with a navigation system and it was identical to mine. The salesperson and the customer relations person at the dealership both agreed completely with me about the difficulty in seeing the screen. I am waiting for the next sunny day to show it to the service manager and hopefully get something in motion that will resolve the problem.
I am wondering if anyone else has had a similar experience with his/ her screen. Any input would be extremely appreciated.
#479 of 1637 Lets do a little figuring

Lets do a little figuring.
If a weight to horsepower ratio is good enough for a Aviator, it certainly should be good enough for a Navigator.
A Lincoln Aviator weighs in at 4957 pounds and has 302-horse power with 300 pounds of torque.
A Lincoln Navigator weighs in at 6041 pounds and has 300-horsre power with 355 pounds of torque.
To end up with the same weight to horse power and torque ratio that an Aviator has, a Navigator’s horsepower will need to be increased to 368, and the torque would need to be increased to 366. (400 lbs of torque would be better)
Can you imagine what we would kind of horsrpower we would have if we used the Porsche Cayenne weight to horse power ratio.
#480 of 1637 I never argue with the facts........guys.

Look, I'm just saying, I've never felt the car was underpowered, that's all. I have dragged heavy cars in tow up Baker grade in California, which summits at 5000 feet, with no strain at all. And, please notice, e350, that none of the cars you listed were on my list of cars I felt were underpowered (Old Tahoes and Sequoia). Like you would tow with a Porsche anyway..... For the record, the 300hp 4V intech 5.4 was put into the 1999 Navigator mid year, or actually, in about December 1999. I know, because I got one of the very last 2V equipped models 260hp, and it did fine as well. Admittedly, I don't pull a house with it, just trailers with cars on them, but it's satisfied me. I'd be interested in a Power Stroke option though......but not a V-10. Unnecessary for me. I would certainly defend your rights to drive one though, if they were available.
#481 of 1637 More Power Continued . . .
May 19, 2003 (4:05 pm)
Perhaps the Ultimate could feature a bigger engine, as many of these models have different engine options.
The Toyotas (Landcruiser and Sequoia) only have tow ratings of 6500 lbs.
With the new F-150 getting 300 hp (and thus the 2004 Excursion), I'm sure more power is in the works for the Navigator.
Incidentally, I'm in Denver, so towing STARTS at 5280 feet!
#482 of 1637 CAFE ratings
May 20, 2003 (5:00 pm)
may influence the engine options, IF, these trucks are subject to them, and I'm not sure which side of the line they fall on.......
May 20, 2003 (8:55 pm)
6000 lbs - the 'Gator is not included
#484 of 1637 Just Wondering,
May 21, 2003 (1:50 pm)
How much Horse Power and torque, do you believe, would be produced with the following?
1) Supercharged 4v 5.4
2) 4v v10
3) Supercharged 4v v10

Is the NAV really DVD-based? Last I read, it was CD-based. I'm about to buy a Navigator myself, and I'm deciding on the NAV.
