School had a fundraiser today where a local Ford dealership would donate $20 for taking a test drive. Figured it was a good opportunity to help out the school and test drive a new 2015 F150. To my surprise, they had 12 different new Fords for the taking including an SCrew Lariat 4x4 5.0 and an SCrew XLT 4x4 3.5 Ecoboost. Part of the route was pulling onto a stretch of 4-lane highway which gave me a chance to get into it a bit. First, I drove the 5.0. I was expecting similar acceleration to the Ecoboost. It was smooth, but didn't offer any wow factor and seemed to shift too early before getting into it's powerband. Acceleration was kind of almost like the e-brake was partially on and required a lot of throttle to get her moving. The Ecoboost throttle response was much better and did provide that wow factor I've come to enjoy. It felt stronger than my 2013 on stock tune and seemed to have better shift points. It felt like Ford has definitely made the stock feel much more crisp. Bottom line, I was amazed at the difference in feel between the 5.0 and 3.5 Ecoboost. I was really expecting them to be fairly close in acceleration. The low end torque of the Ecoboost really separates it apart. I can't imagine the difference there would be hooked up to an 8,000 lb. travel trailer.
