Milan replaced the Sable as Mercury's midsize sedan for 2006. Built on a front-wheel-drive platform like the Sable, the Milan shared its basic architecture with the Ford Fusion and Lincoln Zephyr. All three were based on the Mazda 6 from Ford Motor Company's Japanese affiliate, but were slightly larger. Aimed at more youthful buyers, Milan was the most affordable car in Mercury's lineup. Mercury also said it was the first car in this segment in a decade. Milan was offered in base and uplevel Premier models, both available with either a 160-horsepower four-cylinder engine or a 221-horsepower V6. The four-cylinder came with a five-speed manual transmission or an optional five-speed automatic. V6 versions used only a six-speed automatic. Antilock four-wheel disc brakes were optional for the base Milan, standard for Premiers. Traction control was available on V6 versions. Base models had 16-inch wheels, versus 17-inch for Premiers. Standard equipment included a six-way power driver's seat, CD player, remote keyless entry, and power heated mirrors. Front torso and head-protecting curtain side airbags were optional, as was a sunroof. Premiers came with leather upholstery and offered a choice of metal or wood interior trim at no extra cost. Two-tone leather was available, too, as were heated front seats. Milan's rivals included the Honda Accord, Nissan Altima, and Toyota Camry.
