There's nothing new in the 5.0, dual VVT and DOHC V8s have been around and proven. Forced induction on gas engines have historically been unreliable and DI is still maturing. Couple that with trying to prove a V6 can do the work of a V8 and its just a long, uphill battle. If I was in the market though I'd strongly consider one though, but I always like the new gadgets.
its new in anything domestic... Find a Ford dodge or gm with dohc and vvt on the same motor. I will concede on it being just a v6 but my point was fords new 5.0 is just as new and fancy. so the argument of fearing something holds little weight. And why is di maturing? It's Been in diesels for 16 in fords alone.
Even in the case of these two engines, you still have a competitor that has it's roots in traditional V8 design. You want to call them both apples so bad you're missing the point. Are they both new, yes. Are they both new concepts, given the platform in which they are being installed and the loads they'll be taking on, no. V8's have been used for hauling and towing for a long time. V6's, not so much.
