Boy I sure hope that the 3.5EB buyers got the 7yr/125k warranty..

I hope that start/stop is something that the owner can turn off.
I drove a Mercedes b class in Belgium that had auto stop/start and a manual trans, no less. It worked far better than I ever could have imagined. I couldn't outsmart or attempt to get going too fast for it. And you can bet the starting system is built to a higher duty due to the obvious added use.

What about an extra 50-80 ft-lb, a lower rpm range, and more mpg's? Really, the exact same set of advantages the eb has on the 5.0.

I read yesterday that if you tow or use 4wd it's automatically disabled and that you can turn it off.

I remember when I took the starter out of my 92 F150 to have it rebuilt and how disappointed I was in how small it was. That truck had a 351 and the starter wasn't much bigger than a large can of beans. In the 13 years that I had the truck the starter had to be rebuilt twice - so I am leery of Ford saving bucks whenever possible. Plus I am used to starters on my high compression diesel engines that are 3" in diameter and weigh 15 lbs.

Start/stop technology hasn't been in cars that many years. Just from a wear standpoint, the idea of being in a traffic jam each morning where I start and stop 20? 50? times. Taking an engine from 0 rpm to 2000 rpm during a start event over and over and over just on the morning commute? What happens after 100k miles, 200k miles, ...

This is one "feature" I would find a way to flash out of the truck. I'm really not a luddite (afraid of new tech) I just don't like being a mine canary.

It isn't like it would be a cold start each time though. I like this idea a lot more than shutting cylinders off while driving.

Seems like trading wear on the motor for wear on a starter.

Im guessing 2.7L hp to be in the low 300's with tq around 400 ft/lbs. 5.0 unless DI it will stay around teh same maybe a 10-15hp bump and the 3.5TT with 400hp and 475 ish ft/lbs.

I seriously doubt it's that big of a deal. Most cars sold in Europe have it already and the starters are beefed up to handle the increased duty cycle. Nothing engineers can't design around.

So we gotta take the tune from the 2015+ trucks and put it in the 11-14 ecos is what your telling me?

Ill assume its the same motor.
