Just been reading the various reviews on the 2018 Lincoln Navigator.

Ford pulled out all the stops and has blown the competition including
theÂ* Cadillac Escalade and Infiniti QX80Â* away with this one.

3.5L twin turbo, 450hp, over 500 lb ft of torque, 10 speed transmission,
Â*6 adaptive performance settings, premier seating for all and an
interior fit and finish that is superior to any of it's competition.

Quite a price tag though.Â* Starts at $76K.Â* $96K typical.

Mrs.E. loves Navigators.Â* She has had three of them in the past.
Gotta keep her away from this one.





Heheh...what does that barge weigh, three tons?, and with a 3.5 liter
engine, the same size as in my little truck and a Toyota with V6? With
twin turbos? Not an engine that is going to last long, pushing an
aircraft carrier.

It does 0-60 in a little over 6 seconds. That doesn't seem to be
underpowered. I doubt Mrs E will keep it long enough to wear out the
engine.


I wasn’t questioning the horsepower output, but the wisdom of powering a
three ton car with a small engine.


I don't know enough about cars to comment intelligently however I don't
think today's engines suffer from the "worn out" issues of those of the
past. Geared properly (10 speed transmission) I don't think the
Navigator V6 is working much harder than the V6 in my Canyon that has an
eight speed transmission or the V6 in your Tacoma. The twin turbo makes
it more complex for sure but modern turbos have a decent reputation for
longevity. Lots of cars and trucks have them.

In the old days the main reason an engine "wore out" (except for a
catastrophic failure) was due to worn rings, cylinders and valves.
Their condition was manifested by burning oil, leaving blue clouds of
smoke and running rough with a cylinder or two missing due to lack of
compression. You don't see that much anymore due to advances in
material sciences and hard coatings on the cylinder walls, rings and
valves. Lots of cars and trucks are used daily now-a-days with 150K to
200K miles on them and they don't burn any oil.
