First generation (2006)
Lincoln presented the 2006 Zephyr in concept form at the 2004 New York International Auto Show, featuring Lincoln's signature split-wing/waterfall grille and quad projector beam headlights. Chrome trim extended along the Zephyr's beltline while the car's rear fascia featured LED taillights and dual chrome exhaust tips.
Lincoln introduced the production Zephyr in the fall of 2005 for model year 2006, sharing Ford's CD3 platform with rebadged Ford Fusion, Mercury Milan and Mazda 6. The Zephyr's powertrain was a 3.0 L DOHC Duratec V6 with an Aisin 6-speed automatic transmission. Featuring an instrument panel unique to the Lincoln along with other details, the 2006 Zephyr started at a base MSRP of $28,995 USD, ranging up to $35,340 USD.[5]
Though slightly smaller and front-wheel drive, the Zephyr was marketed as a replacement for Lincoln's previous entry level mid-size, the rear-wheel drive Lincoln LS. To facilitate a smooth transition, the Zephyr and LS were sold parallel to each other during the 2006 model year, the first model year of the Zephyr and the last for the LS. For 2007 the model was renamed MKZ, and took over the LS' market with sales beginning in September 2006. Lincoln had previously used the Zephyr nameplate for a smaller car competing with the Packard One-Twenty, and the LaSalle, a smaller Cadillac.
The Zephyr featured interior detailing and an instrument panel distinct from the Fusion and Milan, using genuine ebony or maple wood inserts along with chrome-bezeled gauges, circular, chrome-finished vents and a satin-nickel center stack with the radio and climate controls. The steering wheel was leather-wrapped with genuine wood grips and satin-nickel audio, climate, and cruise control buttons. White LED backlighting was used for the Zephyr's controls and instrumentation. Leather seating surfaces were standard in all models.[6]
Other standard features included cruise control, automatic headlights, fog lights, power door locks, "global" power windows (all windows can lower simultaneously at the push of a button), power adjustable and heated mirrors with puddle lamps, remote keyless entry, a tilt and telescoping steering wheel with redundant audio and climate controls, dual-zone automatic climate control, a universal garage door opener, 10-way power driver and front passenger seats, rear-seat reading lamps, and a six-speaker audio system with an AM/FM stereo radio and a six-disc, MP3-compatible CD changer. Optional in the Zephyr was a power moonroof, a DVD-based satellite navigation system and HID headlights. All Zephyrs featured low-profile tires on 17x7.5-inch wheels with painted aluminum versions standard and chrome versions optional. HID headlights were available.
Safety features included standard dual front-side airbags, front seat-deployed side airbags, and curtain airbags that extend from the front to rear seats.[7]
Beginning with the Zephyr, Lincoln offered and an industry-first THX II-Certified audio system with a six-disc, MP3-compatible CD changer and ten speakers and digital signal processing. For the 2007 MKZ, Lincoln subsequently expanded the THX specifications to include THX II Premium Certified Audio System, 5.1 Surround Sound, 12-channel amplifier, 600 watt power, and 14 speakers, the latter with two subwoofers and a center channel speaker array with THX Slot Speaker(TM) technology. The system included a 10 GB hard drive marketed as a jukebox, that could hold up to 2,400 tracks.[8]
Lincoln offered the Zephyr with standard heated seats and optional and cooled front seats. With the MY 2008 MKZ, the climate controlled front seats, heated and cooled, became standard equipment, pioneered in the 2000 Lincoln Navigator and provided by Amerigon. User-controlled by dash-mounted switches, ambient cabin air was drawn into the system, either heated or cooled by a solid-state heat pump using a thermo-electric device (TED) and then circulated via a fan through seat cushion and seat back ducts.[9]
Co-developed withe the Fusion and Milan, the Zephyr used Ford's CD3 platform, itself derived from the natively front-wheel drive (FWD) Mazda 6, employing a coil-over damper, short- and long-arm (SLA) front suspension with double-ball-joint control arms and independent multi-link rear suspension with lower control arms and a 17 mm stabilizer bar. Spring rates, bushings, and dampers were specially tuned for the Zephyr to provide excellent ride comfort without compromising handling. The Zephyr featured standard four-wheel anti-lock disc brakes with traction control. The sole engine was an all-aluminum 3.0 L DOHC Duratec V6 producing 221 hp (165 kW) at 6250 rpm and 205 lb·ft (278 N·m) of torque at 4800 rpm. This engine was mated to an Aisin 6-speed automatic transmission and had a final drive ratio of 3.46:1. This powertrain was identical to the V6 powertrain available in the Fusion and Milan from 2006 to 2009.[10] With this powertrain the Zephyr could accelerate from zero to 60 mi/h in 7.5 seconds.[11] The FWD Zephyr came with a 17.5 usgal fuel tank and is rated to deliver 17 mpgus in city driving and 26 mpgus on the highway based on the revised 2008 EPA fuel efficiency measurement standards.[12]
Zephyr to MKZ transition (2007)
For 2007, Lincoln reintroduced the Zephyr as the MKZ — as the brand, following a broad market trend toward alphanumeric nameplates, across its model range. At its 2006 introduction, Lincoln originally suggested pronunciation of the nameplate MKZ as "mark-zee," subsequently shifting to "em-kay-zee" ("em-kay-zedd" in Europe) after noticing focus groups and dealership personnel naturally using the latter pronunciation.[13]
The 2007 MKZ was presented at the Chicago Auto Show in February 2006. Revisions included optional all-wheel-drive along with Ford's then-new all-aluminum 3.5-L DOHC Duratec 35 V6, tuned to produce 265 hp (196 kW) at 6250 rpm and 249 lb·ft (337 N·m) of torque at 4500 rpm — using regular-grade gasoline.[14] and achieving 17 mpgus in city driving and 25 mpgus on the highway in front-wheel-drive models.[15] Revised Standard and optional variants of the MKZ's 17 × 7.5-inch wheels were offered.
For 2008, the MKZ received as standard equipment Sirius satellite radio, perforated leather seats, a reverse sensing system, a tire pressure-monitoring system, and
