Mercury's rear-wheel-drive full-size sedan shares its design with Ford's Crown Victoria and is among the few body-on-frame automobiles. Grand Marquis groups models under GS and LS labels, and also offers the performance-oriented Marauder. Front side airbags are standard on Marauder and available on the others. ABS is standard; traction control is standard on all but the base GS, where it's not available. Front side airbags are standard on Marauder, optional on LS. The only engine is a 4.6-liter V8 teamed with automatic transmission. GS and LS models have 224 hp. An optional LS Handling Package includes dual exhausts for 239 hp. Marauder has 302 hp, plus a sport suspension, monotone exterior appearance, and 18-inch alloy wheels vs. 16s on other models. It comes with front bucket seats, center console, and floor shift. Other models have a front bench seat. All but the base GS have standard power-adjustable pedals. Optional laminated side-window glass is designed to reduce wind noise, limit breakage in a collision, and improve security against "smash-and-grab" theft. Also sharing this basic design is the Lincoln Town Car. Grand Marquis' performance and accommodations mirror those of similarly equipped Crown Victorias.
