Ecoboost vs Hemi

Having towed our company's 7000 lb rated utility trailer close to fully loaded with the following vehicles, 2011 Ford F150 3.5 Eco Boost, 2012 Dodge 1500 with V-8 Hemi and now a 2012 Ford F150 with 5.0 V-8. The Eco Boost towed the best when in the hills due to the turbo, then the Dodge with the Hemi then the Ford with the 5.0. All three had gears that were very close. Both Fords with 3:55 and I can not remember what the Dodge had but it was very close. The Eco Boost and Hemi both had around 65-70K on them the 5.0 currently has 68K on it.

Never had any turbo problems with it and it currently has around 156K on it. The Hemi has around 165K on it and is now used for close by stuff no long trips or towing. On every long trip or attempt to tow it throws check engine codes, and results in a trip to Dodge for more wasted dollars. It also had the softest rear springs out of the three.

Good luck on what you pick or do.

I have the same experience when I had my 2011 Ecoboost 3.73 6-speed versus my BIL's 2012 Hemi 3.92 6-speed. Our trailers at the time were very similar with maybe a 300 lb difference between them. Pulling away from a stop, you had to give the Hemi more throttle to get the rpm's up. You can immediately tell that the Ecoboost had way more torque and power than the Hemi did below 3,500 rpm. The big difference is going up hills. His dropped down to 2nd at around 4,500 rpm to pull the hills at 65 mph while mine would pull the same hill at 2,800 rpm in 4th doing 65 mph. Both will pull the weight, but they just do it differently. The Hemi just needs lower gears with more rpm's(4k-6k) to do the same work that the Ecoboost can do at higher gears and lower rpm's(2k-4k).

As far as the displacement argument goes, the Ecoboost has more effective displacement due to forced induction cramming the equivalent air of a larger engine. At full boost at peak torque(2,500 rpm) the Ecoboost has an effective displacement of a 7.0L while the Hemi is a 5.7L throughout its whole rpm range.
