Now I have heard many rumors regarding the EcoBoost (formerly know as Twin-Force) V6, but haven't seen any factual basis backing the #'s. Will wait until Ford releases more details. This EcoBoost design has also been speculated to go on the 6.2L Boss (Hurricane) motor at some point.
my point was, it's a car motor at this time, so don't expect those same numbers in a truck - not just mpg but the hp/tq numbers too. Ford, unlike toyota and chevy, will not put a motor with a 4000rpm peak torque in a truck. They'll sooner add 3 ft to the intake runners to get the low end torque and lose hp in the process rather than do that...
remember those late 80s truck version 5.0s with the foot tall intake? the ones that made 140hp cause the mustang's blistering 215 was way too much, hehe...
