I'm wanting to get something with some serious oohmp under the hood, and haven't been able to find an 5.0 XKR in a color combo that just nails it for me.

However, I am seeing some 2013-2014 XF 5.0 Supercharged in appealing color combinations.

What I can see is that 2013+ XF superchared have a possible advantage of an eight speed gear box.

A google search shows the weight between the two as being about 50-100lb's. XF is 6" longer and 6" taller.

The performance of the two after re-chipping the XF should thus be similar.

Is there any one with experience with both to chime in?
