2015 Lincoln EcoBoost vs the Ike Gauntlet

Yes, impressive for such a heavy vehicle.
I'm sure the cold air was helpful too.

Where is the GMC half of it (Part 2)?

They are still trying to get up the hill, that thin air really strangles the N/A engines. :W

The Ecoboost is the perfect engine for the Navigator. Lincoln is doing very well these days. I was surprised to see that the Ecoboost horsepower rating (380 HP) was listed in the 2015 brochure as requiring 93 octane premium fuel. I did not realize that was a requirement. Either way, impressive numbers.

That is why we bought a 2015 Expedition with the 3.5 Ecoboost rather than a 2015 Navigator. The Navigator requires premium, the Expedition only requires regular. Just annoyed to me to have to pay a 30 cent per gallon premium just to own our previous Navigator. Did not want to do it again.

You use premium fuel for max horsepower.
With the lower octane fuel, the power is reduced.

Here's a follow up including the GMC and a drag race. :B

GMC Ike Gauntlet


Go Patriots....:p

You got suckered. Its the same engine. WHy would the surrounding vehicle determine octane requirements? It doesn't...

This sounds very similar to early 200x Acura MDX vehicles which Acura called out premium octane fuel for. A few years later Honda come out with the Pilot. Exact same motor/drivetrain only requiring 87 octane. Acura owners were like WTH, but eventually smelled through the BS and now most in the know just run 87 octane and let the knock sensors and adjustable timing do their thing.

The Navigator has a slightly hotter tune on it, though; that might be the difference.

These are 2 great looking trucks. A variant of one or the other will be our next family hauler, and it looks like either would make a fine choice. I love the EB in my F150, but the 6.2/8 spd would probably get the job done, too!

The GM 8 speed tranny seemed to do an excellent job. The GMC appeared to me to be towing quite effortlessly while the Ecoboost was on the floor more than once. The big V8 got better MPG as well although it was 11 seconds slower due to being slowed up more in traffic. Both vehicles did the job and both are ungodly expensive.
