I think it's funny they felt the need to completely redesign a motor that is still fairly young and new and suppose to be indestructible. I like the transmission though. I would love to see a ten speed in the HD line ups with a 2 speed rear axle option.
Take a truck like my 2013 Ram. It would be the cat's meow if I could have 3.42:1 for my everyday ventures and then when I hook to my rig push a button and have 4.11:1.
Not sure why you consider making improvements on an engine that has been vehicles for over decade is funny. I would think it would be more funny or odd for a manufacturer in this technology driven age to wait for the competition to pass them and react.
The 3.5 Ecoboost has been in the F150 towing heavy loads (for a 1/2 ton series truck) for decades? Huh, new one for me. I thought it was an all new engine and technology for the F150.
:) Hi, I believe that he said for over a decade, which could mean eleven years. "for decades? Huh, new one for me." This engine started in the Taurus before the F-150.
It's not the same engine that was in the Taurus. Same displacement and has turbos yes but not the same.
:) Hi, other than having less torque, and being in a front wheel drive vehicle, what makes this a different engine? As far as I'm concerned, a few minor differences doesn't make it a different engine.
This is what I copied from Popular Mechanics webpage:
"While it might be convenient to think that this is simply the Taurus SHO engine turned 90 degrees and dropped into the truck's cavernous engine bay, that would be completely wrong. The aluminum block is all new because it bolts to a different transmission from the front-wheel-drive applications. The engine also has stronger main bearings. Like all 2011 F-150 powertrains, the 3.5 liter is matched to Ford's six-speed automatic. Additional major differences between the engines include unique heads that feature individual cam phasers for both intake and exhaust; the fixed-geometry turbochargers flow more and produce more boost (13 psi versus 10.5 psi); the main cooling system is upgraded.
These changes enable the F-150's version of the EcoBoost to deliver:
• 365 horsepower at 5000 rpm (on regular fuel)
• 420 lb.-ft. of torque at 2500 rpm (up to 90 percent of peak torque from 1700 rpm to 5000 rpm)
• 11,300 pounds maximum trailer-towing capacity "
From my own understanding the ecoboost in the F150 had to be built "stronger" for the increased duty-cycle or durability for the truck that would not be seen in the car.
