the 4.6L SOHC Modular V8 debuted under the hood of the Lincoln Town Car. It was the replacement for both the 302 and 351 cubic-inch Windsor V8 engines; in 1992, it became available in the Crown Victoria and Grand Marquis. Although the torque peak for the Modular V8 was 1,200 rpm higher than for the 302 V8, the 4.6L was available with up to 60 more hp (with optional dual exhaust). 1998 upgrades In 1997, Ford significantly upgraded the exterior designs of all three Panther platform cars. The Town Car received the most extensive changes with its entire body being restyled. To increase parts commonality between the two, the Crown Victoria was redesigned to share the rear roofline (and much of the exterior sheetmetal) with the Grand Marquis, which saw minor cosmetic changes itself. Underneath the sheetmetal, a Watt's linkage was added to the rear suspension (still a live rear axle) in an effort to improve handling. Third generation (2003–2011) For 2003, Ford Chassis Engineer Trever Skilnick completely redesigned the frame of the Panther platform using a hydroformed steel frame and a bolt-in cast aluminum stressed member that held the powertrain. The front and rear suspension were also completely overhauled in an effort to improve handling; rack and pinion steering replaced the recirculating-ball design. While the sheetmetal of the Crown Victoria was left alone, the Grand Marquis and Town Car both received updates to the exterior and interior in an effort to bring them in line with the rest of their respective product lineups. The "Cast Aluminum #2" frame crossmember won Casting of The Year for Tier 1 supplier CMI - Hayes Lemmerz, and the new chassis was reviewed favorably by journalist Dan Neil of the Wall Street Journal . For 2003, Mercury introduced the Marauder, a high-performance variant of the Grand Marquis. Designed in a similar fashion as the 1994–1996 Chevrolet Impala SS (with black also being its most commonly available paint color), it featured the engine of the Ford Mustang Mach 1. The Marauder sold poorly; it was dropped after 2004 after just over 11,000 were built. Models In total, twelve vehicle nameplates were produced under the Panther platform, with the Ford LTD Crown Victoria, Ford Crown Victoria, Ford Crown Victoria Police Interceptor, Lincoln Town Car, and Continental Mark VI produced exclusively on the architecture.
