Consisting of four vehicles for 2010, the Mercury product lineup offers a mosaic of old and new American automotive philosophies. Representing the old guard, the Mercury Grand Marquis is a rare breed in 21st century car dealerships as a large rear-wheel sedan. Along with the Mountaineer sport utility vehicle, the Grand Marquis is unchanged for the 2010 model year. The Mercury Milan has received an extensive exterior and interior redesign for 2010. One major addition to the 2010 Milan is an available hybrid version combining momentum of a four-cylinder engine and electric motor to generate up to 41 miles per gallon fuel economy in city driving. The Milan Hybrid joins the Mariner Hybrid as two Mercury products using advanced powertrains to achieve high efficiency. For 2010, the Mercury Sable sedan has been cut from the model lineup.
