Ecoboost engine question

My guess is that the 3.5 is maxed out with the 11,300lb tow rating in an F150. Add the extra weight of the F250/350 and the 3.5 would have a hard time reaching the 15,000+lb tow rating offered with the 6.2. It works fine in it's own element.

The 3.5 Ecoboost has 15 lbs. more torque than the 6.2, not to mention the 6.2 develops max torque at a relatively high 4500 RPM vs. the 3.5 Ecoboosts's much lower, diesel-like, 2500 rpm. I would think the limiting factor (ref tow capacity) for the 3.5 Ecoboost F150 is the 1/2 ton drivetrain and suspension.

Concerns about the 3.5 Ecoboost duty-cycle and fuel economy aside, I believe the 3.5 Ecoboost's torque characteristics would provide much better realworld performance (to include towing) than a 6.2 in a F250/350 chassis. Torque does all the work. The 3.5 Ecoboost has more and at a much lower RPM than the 6.2.
