I agree it would be cool. Right now, there are a few GM selections that offer some V8 rear drive variety. Cadillac, the past Pontiac G8, GTO, Chevy's SS or Caprice models give some options. Dodge has the Charger and Challenger.
Maybe a V8 Lincoln or a return of the ever faithful Crown Victoria, Grand Marq and Marauder. They tried the T-bird with the retro model. That really didn't do as well as Ford thought it would. The Lincoln LS was a neat car. It would be neat to see that return. Falcon, I'm afraid, will stay an Australian model, never to return to the states.
But upon a little consideration, I don't want Ford to return all its old name plate and ruin their legacy with a something that won't go over well. Like the T-Bird all over again.
Ford is pretty in tune with the market. I think if they think they can sell it they would. As much as I love the V8, there seems to be a lot of evidence that it won't be around much longer. The rise of the turbo 4s and 6s would indicate the impending doom of the V8. I hope I'm wrong.
I don't see how a turbo 6 has any better gas mileage than an equally powered V8. Every body seems to equate turbo charging with fuel economy. Maybe its how you drive it or maybe its just a sales gimmick. I'm not drinking the Koolaid and jumping on the turbo bandwagon just yet.
Getting a little lengthy. But, yes, I would love to see more V8 rear drive Fords.
