I lot of interesting points by many of the posters here...two points for me are salient but somehow contradicting. As one poster mentioned, the mustang is set to outpace sales of the entire lincoln line-up; however, the market is so small in the luxury coupe segment! I heard former prod development VP Derek K reply as recently as the 1st quarter, during a Q&A session after the earnings annoucement, that Lincoln is not considering entering into this segement because the market is not large enough.
A lot of the speculation has been fueled by media outlets. Two weeks ago when Lincoln announced the new ad campaign and released a couple of teaser promotional videos on-line, viewers were given a brief glimpse of what appeared to be a mustang chassis during a scene in a manufaturing plant. This seemed to have stoke the fire. I had a conversation with a finance colleague who is working on the lincoln product cycle for the next five years. He divulged quite a bit of confidential information to me, but a rear wheel drive coupe was not mentioned. He seemed eager to share lincoln news and I think he would have mentioned confirmed this rumor had it been true.
