The v6 is supposedly going to have more torque and more importantly it will come on a lot lower in the rpm band.
OK, been ignoring all the pissy 6.2 vs 3.5 arguments- but this is just a bunch of BS that keeps being thrown out there.
At wide open throttle- yes, a smallish turbo engine will produce more torque than a big N/A V8, and do it lower in the RPM band. However, if you drive it like a normal person on a normal day- ie light throttle 99.999% of the time, the big V8 will have a massive torque advantage over a small V6 that is not in boost.
Hell I can tell a huge difference between my friend's Corvette with a high compression 346 V8 engine and my 03 Cobra with a low compression 281 V8. Just cruising around town, taking off from a stoplight- the Vette feels so much more powerful and responsive. However, crack the throttle and get some boost in the Cobra engine, and there is no comparison. The Cobra produces hundreds of HP and Ft-lbs of torque more than the Vette and just smokes it.
So bottom line- everyone quotes the numbers and looks at the curves, but that is all measured at WIDE OPEN THROTTLE. Who drives around with the pedal on the floor until it's time to brake? Now, I know that Ford has small, responsive turbos on the engine and it'll get into boost at way less than WOT, but then the fuel economy goes to hell- which is the main argument for the using the smaller, more complicated and expensive to repair engine in the first place.
