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

Ford pulled out all the stops and has blown the competition
including
the Cadillac Escalade and Infiniti QX80 away with this one.

3.5L twin turbo, 450hp, over 500 lb ft of torque, 10 speed
transmission,
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. Starts at $76K. $96K typical.

Mrs.E. loves Navigators. 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.





You probably are right. Pretty soon we'll be seeing one liter engines
zipping "funny cars" down the dragstrip!

Indy cars have 2.2L engines pushing 600+ HP.
