The center console features generously sized, chrome-ringed cupholders and an armrest that slides forward to accommodate drivers that may have moved his or her seat forward on its tracks. Outward vision through the windshield is good in spite of the tall dashboard. Vision out the sides is decent, aided by big, heated outside mirrors. The rear shelf, however, is so high that it blocks a fair amount of rearward vision through the mirror and increases the size of the blind spots.

Ergonomics are quite good, even if the Zephyr's highly stylized, formal dashboard treatment is a bit imposing. The deep-set, electroluminescent speedometer and tachometer are on the small side, but are clearly legible nonetheless. A trip computer/vehicle information display is nestled between the two primary gauges, as are warning lights and the coolant temperature and fuel level indicators.

All gauges and controls feature cool white nighttime illumination that conveys an appreciable sense of class. However, driving at dusk, we noticed that the white back-lit script blended into the silver dashboard and steering wheel trim, making the buttons somewhat difficult to read. That said, all controls, buttons and knobs have a genuine upscale feel in their operation. An elegant analog clock located high in the center of the dash further contributes to the Zephyr's air of sophistication.

Leather upholstery is standard, and while it does not feel as buttery smooth as that in, say, the Cadillac CTS or Lexus ES 330, it feels better than that of the BMW 3 Series or Mercedes-Benz C-Class. Front seat heaters are standard, while seat coolers are available. Both offer three settings. Ordering the cooled seats brings with it perforated leather upholstery in place of the non-perforated leather on all other Zephyrs.

Interior trim is remarkably nice, with padded materials covering the dash top and door panels. The silvery metallic plastic trim looks attractive, offset as it is by generous swaths of genuine wood trim and chrome accents. We wonder, however, about the long-term durability of that silver stuff; we've seen similar material on other cars get scratched easily and often over time.

Zephyr's steering wheel is a particularly good-looking part of the interior. The four-spoke wheel is rimmed most in leather. Two lovely wood pieces, at 8 o'clock and 4 o'clock where one's hands belong, match the wood trim elsewhere in the vehicle.

Controls for the standard, six-speaker stereo, as well as those for the optional thundering THX Audiophile II system, are straightforward and clear. The optional, easy-to-use touch-screen navigation system unfortunately gobbles up the dashboard real estate usually reserved for the radio, thus most audio functions have been incorporated into the touch screen. At least a conventional volume knob has been retained even with the navigation system option, which includes the THX sound system.

The navigation system itself is about par in terms of ease of operation and reliability, capable of speaking English, French and Spanish, and it even vocalizes the names of the certain streets when giving directions. Not that it can boast perfect pronunciation, though; during a test drive through Beverly Hills, California, the navigation system's friendly female voice directed us to turn left on Rodeo Drive, pronouncing as a cowboy would when describing a cow-roping event.

The dual-zone automatic climate controls are of the button variety, rather than the preferable knobs. That said, they are quickly learned. Clearly, Ford paid attention to the quality of feel of all buttons inside the Zephyr, as all are pleasant to operate and far from cheap-feeling.

Rear seat occupants enjoy generous accommodations, provided there are no more than two of them; three is a squeeze. Rear seat comfort is good, and a fold-down armrest with two cupholders adds comfort. Outboard headrests are fixed into the tall, but nicely contoured seatback.

Interior storage space is average. The glove box is modest, but the center console and door panels can hold several CDs and other items. One 12-volt power point is mounted alongside the fold-out ashtray, with another located in the center console. During our test, we found ourselves longing for some sort of console cubby that could hold cell phones, wallets and other small things. At least the cupholders are large and accommodating.

Trunk space is generous at 15.8 cubic feet, one cubic foot larger than that of the Infiniti G35 and two cubic feet larger than the trunk of the Audi A4. Liftover height is low, and the cargo floor is wide and flat. We only wish there was an assist grip somewhere inside the decklid lining to allow one to close the trunk without touching dirty sheetmetal.

All told, the Zephyr's interior feels elegant and modern. And while it doesn't quite match the refinement of, say, the BMW 3 Series or Acura TL, but it is a huge accomplishment for Lincoln and one that should more than satisfy its owners.
