I usually just listen to the audio version of this show, but I ended up going back for the video version this time.

Jump to about minute 33 to get into the presentation of the new CTS.

Jump to about minute 39 to see comparison shots between components of the 2013 and 2014 versions to see how they cut down 250lbs between generations.

All in all, some pretty good car porn:
