To help differentiate the upgraded 2007 Lincoln MKZ from the one-year-only Lincoln Zephyr, a redesigned grille, a refreshed front fascia, and new 17-inch wheels with a machined finish mark the new car – no pun intended.

Everything else about the 2007 Lincoln MKZ is carried over from the Zephyr, including its impressive 600-watt THX-II Certified audio system with 14 speakers.
