Ultra Cadillac rumors go round and round

...and round and round. At this week's SAE World Congress in Detroit, GM's head of global engineering, Jim Queen, hinted that rumors of an Australian developed Cadillac flagship and V-12 engine might not be as out of the question as we've heard. What I'm seeing is an unintentional leak at first, followed by an over-zealous denial that backfired, and now Mr. Queen giving Cadillac fans a wink and a nod that this product is coming. I'd expect a Cadillac flagship, with a V-12 as an optional powertrain by 2010.
