If the Expedition had the following engine options, which would you choose?

[Alwayz]

5.4 Supercharged v8 for the feel and the extra torque from the 5.4.

I'd take either the

5.4L v8 supercharged 380hp 450 lb-ft 13/17mpg

or the

4.4L Diesel 330 hp 520 lb-ft ~16/22mpg


I'm actually doing research on supercharging my 5.4 after I rebuild it!

I have driven the Eco boost V6 F150. I think for an everyday use and for the weekend light towing and such the 3.7 would be fine. Plus, the turbos on these could be tweaked to squeeze out a few more ponies.

 

[Gary-Kq6rt]

Tough call. I picked the 6.2, but the diesel would probably be the best all around choice.

Rudolph's child. I really with we Americans would build a mid size turbo Diesel. I've got the 7.3 the in the 4 door long bed. The Excursion in not much smaller. THAT is the reason I bought the "small" Expedition.

im not sure how you came up with the MPG ratings but i think a twin turbo v6 and the diesel would both do far better, at least on the highway mileage.

The Cayenne Turbo S is a 4.8L V8 and does 12/19mpg. so i think it would be safe to say a twin turbo 3.7l v6 SHOULD be able to do like 18-22 mpg city. especially if tuned properly.


HOWEVER i would take ANY mpg had it came with the a twin turbo 6. Ford is supposedly releasing an ecoboost model for every car they sale by 2012...so itd be cool to see them do it to the truck/suv.

should ammend the options for a Twin Turbo V6 tuned for Bio Fuel(E85).

tuners are tuning forced induced cars with E85 because states are banning race fuel for global warming reasons....cali especially. however e85 is super cheap compared to 91 and higher octane plus the e85 has better cooling properties allowing tuners to use more advanced timings and more boost without encountering detonation.



edit:
just realized ford does have an ecoboost f150. now that i think about it, i think its ridiculous that ford just threw the sho motor into a truck. they should have retuned it for the application...that being said, ive always been a turbo guy. only with a turbo can you use a purge valve as a diy boost controller and instantly double your boost...of course fuel needs to be added appropriately, but 450hp shouldnt be hard to extract from the 3.7liter. more efficient exhaust, intake, and a intercooler(not sure if has one equipped) with a boost controller always is good for an additional 100ponies on most turbo vehicles....

While I love the idea of the diesel, I've had an interest in the 2003-04 Mustang Cobras and Lightnings with the supercharged engines. I'd love to hear the whine of an Eaton or Whipple supercharger from under the hood of my Expedition!!

 

[sgtowing]

I'd take the diesel all day long. I would have bought an excursion people want outragous money for an 05 excursion 4x4 diesel. 25k to more than 30k. Horsepower don't do you any good without torque to get you going. especially when you are talking about a vehicle that weighs 5,000#'s plus.

 

[jannypana]

I like the mpg's of the V6, but i'd be embarrassed to say I had it. If the 6.2 and the 5.4 both get the same mileage, and more power goes to the 6.2 I'd say 6.2L.

 

[jacket250]

diesel is the best choice but less people would buy it due to the $7000 it would add to the price of the vehichle. the epa has ruined diesels by putting limits on emissions equipment and even the fuel itself
