Milan replaces Sable as Mercury's midsize sedan for 2006. It shares its basic architecture with the Ford Fusion and Lincoln Zephyr. All are based on the Mazda 6 from Ford Motor Company's Japanese affiliate, but are slightly larger. Milan offers base and uplevel Premier models, both available with a 160-hp 4-cyl engine or a 221-hp V6. The 4-cyl comes with a 5-speed manual transmission or optional 5-speed automatic. V6 versions use a 6-speed automatic. Antilock 4-wheel disc brakes are optional for base, standard for Premiers. Traction control is available on V6 versions. Front torso and curtain side airbags are optional, as is a sunroof. Premiers come with leather upholstery, offer a choice of metal or wood interior trim at no extra cost, and are available with heated front seats. Milan's performance and accommodations mirror those of similarly equipped Fusions.
