Interior design is stronger. The retro-themed cabin of the Zephyr concept did not translate to the production model, but at least the dashboard is not identical to the Ford Fusion's. The control panel is dominated by a center console with aluminum trim, while strips of real wood run horizontally to divide the upper and lower dashboard sections. Round chrome-ringed gauges are simple and classy, and the switchgear comes right out of the Ford parts bin, with controls for climate, stereo, and other features identical in design and operation to many contemporary Ford and Mercury products.

The 2006 Lincoln Zephyr but comes fully equipped with the luxury conveniences that make a Lincoln special. Leather upholstery is standard, and the gauges are electroluminescent with Lincoln's signature white lighting. The company is particularly proud of the optional THX II-certified audio system that is available on the 2006 Zephyr, and is quick to note that a DVD-driven, touch-screen navigation system is also offered.

A full complement of standard safety gear includes side-impact airbags, side-curtain airbags, and "roll-fold" technology for the side-curtain airbags that is designed to inflate the airbag between the window and an occupant's head if the head is resting on or near the glass. Antilock brakes and traction control are standard, but there's no sign of a stability control system for the 2006 Lincoln Zephyr.
