chrome "V8" emblem; the oil filler cap was moved to the passenger-side valve cover and the power steering fluid reservoir was moved off of the engine block onto the radiator shroud. For 2006, revisions to engine tuning added 4 hp to both versions of the Modular V8, for a total of 224 and 239 hp, respectively. In 2007, the engine was given flex-fuel capability (E85). After the 2007 model year, the 239 hp version of the Grand Marquis was sold exclusively for GCC export. All versions of the Grand Marquis were sold with variants of the AOD 4-speed overdrive automatic transmission. From 2003 to 2005, the 4R70W was used. In 2006, it was replaced by the 4R75E shared with the Ford truck lineup. Exterior As part of the redesign, Lincoln-Mercury stylists were tasked with giving the Grand Marquis a more contemporary look, bringing it in line with other Mercury-division vehicles. While largely evolutionary, a number of changes modernized the exterior. In a change similar to the 2003 Town Car redesign, the heavily rounded bumpers seen on the Grand Marquis since 1992 gave way to a squared-off lower look. The trunk and taillight trim was simplified with more contemporary badging. In the front, to improve cooling, a larger grille introduced the Grand Marquis to the Mercury waterfall-style grille trim.

To ease production, the Grand Marquis adopted body-color trim for the B-pillars, similar to the Crown Victoria. In 2005, for a single year, the radio antenna became externally mounted, to the rear fender. After years of declining sales, chrome wire wheel covers were optional from the factory for the last time. For 2006, the Grand Marquis was given a mid-cycle exterior update, in what would be the last styling update for the Panther vehicles. The trapezoidal grille seen since 1995 was replaced by a rectangular one with a waterfall pattern similar to the Montego; the headlight clusters no longer extended to the sides of the grille, in a fashion similar to the 1988-1991 Grand Marquis.
